Icey Hot Puts Scent in the Varnish, Not on a Sticker: Packaging World · Through the Line: Packaging and Processing

• 0:03
  SPEAKER_03: Welcome to Through the Line, the podcast exploring innovations and information across the packaging and processing landscape.
• 0:11
  SPEAKER_03: From topics impacting consumer packaged goods and healthcare packaging to the latest technologies in food processing operations.
• 0:22
  SPEAKER_00: Hey everyone, Matt Reynolds here, chief editor at Packaging World magazine, and this is another edition of the Through the Line podcast.
• 0:29
  SPEAKER_00: Today we're looking at Icy Hot, specifically why the brand put scratch and sniff on its new revive and recovery cartons.
• 0:36
  SPEAKER_00: And it's not just nostalgia, although there is an element of nostalgia for this 80s kit.
• 0:40
  SPEAKER_00: Shoppers in aisles at CVS and Walgreens and just retail settings were tearing open sealed cartons at the shelf level just to smell what's inside.
• 0:49
  SPEAKER_00: I mean, that often happens for any kind of scented or fragranced product, but this is an all-new one, so consumers would be curious.
• 0:56
  SPEAKER_00: And every time that that happened and somebody tore into one of those cartons, that was a unit that nobody could sell.
• 1:02
  SPEAKER_00: So that's not good for the retailer.
• 1:03
  SPEAKER_00: That's not good for the brand.
• 1:05
  SPEAKER_00: So it's an interesting story.
• 1:06
  SPEAKER_00: I hope you enjoy it.
• 1:08
  SPEAKER_00: One quick note before we get into it, though, what you're about to hear is an AI-generated podcast built from my reporting and my interview with Heidi Graham at Opelup, that's the brand owner behind IC Hot.
• 1:18
  SPEAKER_02: Imagine trying to safely transport a really delicate glass vial of perfume inside a heavy, vibrating industrial cartoner and expecting it to survive the entire manufacturing and shipping journey completely flawlessly.
• 1:33
  SPEAKER_01: Literal nightmare to anyone working in packaging and processing.
• 1:36
  SPEAKER_02: Exactly.
• 1:36
  SPEAKER_02: You have the brute mechanical force of high-speed equipment on one hand, and then this absolute fragility of a sensory experience on the other.
• 1:43
  SPEAKER_01: They just don't mix.
• 1:44
  SPEAKER_02: But today, that's exactly our mission for this deep dive.
• 1:48
  SPEAKER_02: We're going to look at how Opella actually achieved this with their new icy hot revive and recovery no-mess roll-on.
• 1:54
  SPEAKER_01: Yeah, and we have some incredibly detailed sources to pull from for you today.
• 1:59
  SPEAKER_01: Notably a really highly technical interview between Packaging World and Heidi Graham.
• 2:03
  SPEAKER_02: She's Opella's packaging innovation lead, right?
• 2:05
  SPEAKER_01: Exactly, along with their product spec sheets.
• 2:08
  SPEAKER_02: Okay.
• 2:08
  SPEAKER_01: So what we are looking at is the successful integration of a friction-activated scratch and sniff sensory technology directly into a folding carton.
• 2:17
  SPEAKER_01: Which is huge.
• 2:18
  SPEAKER_01: It is.
• 2:19
  SPEAKER_01: And the real kicker here is that they executed this without slowing down their standard production equipment, without compromising the repulpability of the substrate, and without obscuring the regulatory drug facts printed on the package.
• 2:33
  SPEAKER_02: It's honestly kind of mind-blowing, but I think to really understand the engineering choices they made, we first have to look at the market realities, the things that forced this packaging evolution in the first place.
• 2:43
  SPEAKER_01: The business problem.
• 2:59
  SPEAKER_02: Exactly.
• 2:59
  SPEAKER_02: And the product itself is this no-mess rollerball sitting inside a glued folding carton.
• 3:05
  SPEAKER_02: Now, if you spend any time analyzing retail behavior, you know the dilemma here.
• 3:09
  SPEAKER_02: Curious consumers occasionally open paperboard cartons to sample new scents.
• 3:13
  SPEAKER_01: Yeah, they really do.
• 3:14
  SPEAKER_01: And in the over-the-counter topical pain category, scent is just a massive purchase drug.
• 3:19
  SPEAKER_02: It's because no one wants to smell like a medicine cabinet, right?
• 3:21
  SPEAKER_01: Right, exactly.
• 3:22
  SPEAKER_01: Consumer data consistently shows that while people desperately want the relief of the menthol, they are highly averse to that medicinal smell.
• 3:31
  SPEAKER_01: So Opelli's formulation pairs that menthol with aromas specifically designed to trigger the alertness centers of the brain.
• 3:38
  SPEAKER_02: But if a shopper can't actually experience that scent profile at the point of purchase, you get hesitation.
• 3:44
  SPEAKER_01: Opellan needed a highly functional way to let shoppers smell the actual product formulation right at the shelf, basically engineering away the urge to tamper with the paperboard cartons.
• 3:55
  SPEAKER_02: Okay, let's unpack this for a second because when I first looked at this, my immediate thought was well, if you need a scent on the outside of a package, why not just slap on a standard like 1980s style scratch and sniff sticker on the line?
• 4:07
  SPEAKER_01: You old pressure-sensitive label.
• 4:08
  SPEAKER_02: We've had that technology for decades.
• 4:10
  SPEAKER_02: It seems like the path of least resistance rather than trying to engineer a totally new coding application.
• 4:15
  SPEAKER_01: It does seem easier, but a pressure-sensitive sticker actually fails the modern packaging test on a few really critical fronts.
• 4:22
  SPEAKER_02: Sustainability being the big one.
• 4:24
  SPEAKER_01: Exactly.
• 4:24
  SPEAKER_01: Sustainability is the most prominent.
• 4:26
  SPEAKER_01: Opel operates as a certified B Corp, which means their sustainability metrics are just rigidly audited.
• 4:32
  SPEAKER_02: Oh.
• 4:32
  SPEAKER_02: So they can't just introduce mixed materials.
• 4:35
  SPEAKER_01: If you introduce a sticker with a distinct adhesive and a different substrate material to the folding carton, you're creating a mixed material package.
• 4:44
  SPEAKER_02: Which severely impacts the repulpability and recyclability of that paperboard carton at its end of life.
• 4:50
  SPEAKER_01: Exactly.
• 4:51
  SPEAKER_01: Plus, from a brand architecture standpoint, just slapping a sticker onto a premium health product disrupts this seamless visual aesthetic.
• 5:00
  SPEAKER_01: So the mandate was crystal clear from the start.
• 5:02
  SPEAKER_01: The sensory mechanism had to be natively embedded into the folding carton itself.
• 5:07
  SPEAKER_02: Okay, so they completely rule out the labeler.
• 5:09
  SPEAKER_02: Now they have to figure out how to get raw, highly volatile fragrance oils directly onto the substrate of a folding carton.
• 5:16
  SPEAKER_01: Which requires a massive shift from mechanical problem solving to deep chemistry.
• 5:20
  SPEAKER_02: So Opella brought together their regional carton converters and this specialized scent technology company called Centosphere.
• 5:27
  SPEAKER_01: And what really stands out in this collaboration is the authenticity of the raw materials they used.
• 5:33
  SPEAKER_02: Yeah, this part is fascinating to me.
• 5:34
  SPEAKER_01: Because Opella didn't ask Ctenosphere to just reverse engineer some artificial approximation of the citrus or the tropical rush.
• 5:42
  SPEAKER_02: No, they provided the actual raw fragrance oil directly from their fragrance house, the exact formulation used inside the roll-on applicator.
• 5:51
  SPEAKER_01: And handed it straight over to Cenosphere for processing.
• 5:53
  SPEAKER_02: So Ctenosphere took that raw volatile oil and microencapsulated it.
• 5:57
  SPEAKER_02: And here's where it gets really interesting.
• 5:59
  SPEAKER_02: Instead of visualizing this as a flat layer, think of it like microscopic bubble wrap.
• 6:04
  SPEAKER_01: Or microscopic structural polymer vaults.
• 6:07
  SPEAKER_02: Yes, polymer vaults.
• 6:08
  SPEAKER_02: So the highly volatile fragrance oil is injected and sealed securely inside these tiny load-bearing spheres.
• 6:15
  SPEAKER_01: And the oil stays chemically stable and protected in there until a specific type of localized pressure is applied.
• 6:21
  SPEAKER_02: Like the acute pressure of a consumer's fingernail.
• 6:24
  SPEAKER_01: Exactly.
• 6:25
  SPEAKER_01: That targeted pressure fractures the polymer shell to release the aroma.
• 6:30
  SPEAKER_01: But the truly brilliant part of Centosphere Engineering is how they design those microscopic vaults to behave on an actual manufacturing floor.
• 6:39
  SPEAKER_02: Because making it work in a lab is one thing.
• 6:41
  SPEAKER_01: Oh, absolutely.
• 6:42
  SPEAKER_01: They engineer the polymer shells so they could be suspended directly into a standard clear matte varnish.
• 6:49
  SPEAKER_02: Which is huge for the converters.
• 6:51
  SPEAKER_01: It is.
• 6:51
  SPEAKER_01: When Opella brought this formulation to their regional carton converters, they were basically introducing a form particulate into a standard fluid.
• 6:59
  SPEAKER_01: Usually converters push back hard on that.
• 7:01
  SPEAKER_02: Oh, yeah, because it messes with the viscosity, right?
• 7:03
  SPEAKER_01: The viscosity, the cure rates, the analogs rollers on the press, everything.
• 7:08
  SPEAKER_01: But in this case, it performed beautifully.
• 7:10
  SPEAKER_02: So by embedding the scent into that standard varnish, they completely bypassed any capital expenditure for the converter.
• 7:16
  SPEAKER_01: What's fascinating here is that the plant manager didn't have to shut down the line to install custom coating heads or retrofit the press at all.
• 7:24
  SPEAKER_02: That is incredible.
• 7:25
  SPEAKER_02: They just ran the scented varnish as a simple spot print operation during their normal flexographic printing process.
• 7:32
  SPEAKER_01: Exactly.
• 7:33
  SPEAKER_01: It acts just like another fluid in the inkstation.
• 7:35
  SPEAKER_01: It was a perfect drop-in solution for the printing phase.
• 7:39
  SPEAKER_02: So the convuters could apply the exact amount of varnish required without altering their standard line speeds.
• 7:45
  SPEAKER_01: But as anyone in processing will tell you, getting a specialized coating to lay down smoothly on a web or sheet is really only the first phase.
• 7:54
  SPEAKER_02: Yeah, the physical reality of the finishing stations is where the real stress test happens.
• 7:59
  SPEAKER_01: Oh, definitely.
• 7:59
  SPEAKER_01: The chemistry works perfectly in the fluid state, but then it hits the physical press.
• 8:04
  SPEAKER_02: And the structural design for this specific icy hot revive and recovery folding carton features some highly specific tactile elements.
• 8:11
  SPEAKER_01: Yes, Opella utilized spot gloss and crucially embossing.
• 8:17
  SPEAKER_02: On the Icy Hot logo, on the word original, and on the rollerball graphic right on the front panel to give it that premium shelf presence.
• 8:23
  SPEAKER_01: And those aesthetic choices immediately created a severe friction point during the initial full production runs.
• 8:29
  SPEAKER_02: Because embossing is essentially brute force.
• 8:32
  SPEAKER_01: Exactly.
• 8:32
  SPEAKER_01: We are dealing with an embossing station, which by definition requires a male and female metal dye to exert hundreds of pounds of localized vertical pressure, or PSI, into the substrate to physically deform and raise the paperboard.
• 8:47
  SPEAKER_02: Wait, so the press is literally applying the exact type of acute localized pressure that the microcapsules were designed to fracture under.
• 8:55
  SPEAKER_01: Yes.
• 8:56
  SPEAKER_01: The factory's own embossing dies were systematically crushing the polymer vaults before the folding carton even made it off the finishing line.
• 9:04
  SPEAKER_02: That is wild.
• 9:04
  SPEAKER_02: It's essentially friendly fire on the production line.
• 9:07
  SPEAKER_01: That's a perfect way to put it.
• 9:08
  SPEAKER_01: So the converters had to execute some incredibly meticulous calibration to resolve this.
• 9:13
  SPEAKER_02: How do they even fix that?
• 9:14
  SPEAKER_01: The press operators had to systematically dial in the embossing pressure.
• 9:17
  SPEAKER_01: They were hunting for a very narrow operational window.
• 9:20
  SPEAKER_02: Applying just enough physical force to deform the paperboard carton and create the visual pop of the logo.
• 9:26
  SPEAKER_01: But keeping the pressure gentle enough that the structural polymer vaults in the varnish layer could pass through the die intact.
• 9:33
  SPEAKER_02: I can just visualize the operators on the floor, pulling sheets off the line, checking the registration, and then literally having to scratch and sniff the paperboard carton to see if the embossing die had ruined the batch.
• 9:45
  SPEAKER_01: Oh, it absolutely required a highly iterative testing loop.
• 9:49
  SPEAKER_01: And the adjustments went far beyond just the mechanical pressure of the embosser.
• 9:54
  SPEAKER_02: What else did they have to tweet?
• 9:56
  SPEAKER_01: They also had to rapidly calibrate the chemistry and the geometry of the varnish application on the flexo line.
• 10:02
  SPEAKER_01: They work directly with Cindosphere to toggle the loading ratio.
• 10:06
  SPEAKER_02: Meaning the specific concentration or density of those microcapsules mixed into the varnish matrix?
• 10:12
  SPEAKER_01: Exactly.
• 10:12
  SPEAKER_01: Because if the loading ratio is too low, the scent just doesn't carry.
• 10:16
  SPEAKER_02: But if you pack too many of these polymer vaults into the varnish, you completely alter the fluid dynamics, right?
• 10:21
  SPEAKER_01: Yes.
• 10:22
  SPEAKER_01: The viscosity spikes, it won't transfer cleanly off the analog roller, and it could severely compromise how the varnish cures onto the substrate.
• 10:29
  SPEAKER_02: So finding that perfect equilibrium was critical.
• 10:32
  SPEAKER_01: Highly critical.
• 10:33
  SPEAKER_01: Furthermore, Heidi Graham detailed how they had to optimize the specific surface area of the varnish applied in line.
• 10:40
  SPEAKER_02: Oh, because you need enough space for someone to actually interact with it.
• 10:43
  SPEAKER_01: Exactly.
• 10:43
  SPEAKER_01: This was a major learning curve during their pilot runs.
• 10:46
  SPEAKER_01: If you limit the designated scratch and sniff area to a small patch, say the size of a standard thumbnail, it simply won't generate a sufficient bloom profile.
• 10:56
  SPEAKER_02: And in this context, optimizing the bloom profile means ensuring the volume and the radius of the fragrance release is potent enough to be registered by someone standing in a retail aisle, right?
• 11:07
  SPEAKER_01: But it's also about the longevity of the functionality.
• 11:09
  SPEAKER_02: Yeah.
• 11:10
  SPEAKER_01: You have to account for multiple user interactions.
• 11:12
  SPEAKER_02: Because it's not just one person testing it.
• 11:14
  SPEAKER_01: Exactly.
• 11:15
  SPEAKER_01: You are engineering for a folding carton that might sit on a retail shelf for weeks.
• 11:20
  SPEAKER_01: You need a large enough geometric surface area, saturated with a high enough density of microcapsules, so that if one shopper scratches the top left corner of the patch on a Tuesday, fracturing 10% of the volts.
• 11:32
  SPEAKER_01: Yeah, then the next shopper can scratch the bottom right corner on a Friday and still get a full robust burst of that energizing citrus scent.
• 11:41
  SPEAKER_02: That makes total sense.
• 11:42
  SPEAKER_02: So the converter was able to adjust the registration and the surface area of the spot varnish pretty quickly on the flexo line until they achieve that optimal multi-use bloom profile.
• 11:53
  SPEAKER_01: Yes, they did.
• 11:53
  SPEAKER_01: But getting a perfectly printed, embossed, and scented folding carton off the converter's line is only one part of the battle.
• 12:01
  SPEAKER_02: Because a controlled factory floor is a relatively sterile environment.
• 12:05
  SPEAKER_02: The true test of this engineering is the violence of a cross-country freight truck.
• 12:09
  SPEAKER_01: Oh, absolutely.
• 12:10
  SPEAKER_01: Once that pallet leaves the dock, it enters a highly hostile supply chain.
• 12:14
  SPEAKER_02: So what did they do to prepare for that?
• 12:16
  SPEAKER_01: The engineering team mandated really rigorous distribution testing.
• 12:19
  SPEAKER_01: The primary concern was the ambient lateral friction.
• 12:22
  SPEAKER_02: Which makes sense.
• 12:23
  SPEAKER_02: When you load these paperboard cartons into master cases, palletize them, and put them on a semi-truck, they are subjected to thousands of miles of constant high-frequency vibration.
• 12:33
  SPEAKER_01: And the expectation was that the cartons rubbing against one another would cause enough sheer force to inadvertently fracture the microcapsules, completely depleting the scent before the product ever reached the retailer.
• 12:44
  SPEAKER_02: It's his basic physics.
• 12:45
  SPEAKER_02: If a localized embossing dye can crush them, why wouldn't the sustained lateral vibration of a freight journey?
• 12:51
  SPEAKER_01: You'd think so, but the testing actually revealed the structural brilliance of using a standard clear flexo varnish as the suspension medium.
• 12:59
  SPEAKER_02: Oh, really?
• 13:00
  SPEAKER_01: Yeah.
• 13:00
  SPEAKER_01: The varnish polymer matrix acted as a highly robust buffer shield.
• 13:05
  SPEAKER_01: Once cured, the varnish held the microcapsules so securely in suspension that the ambient lateral sheer force of transit simply wasn't enough to trigger a fracture.
• 13:15
  SPEAKER_02: Wow.
• 13:15
  SPEAKER_02: So the vaults are designed to fail under acute vertical pressure, like a fingernail, but they can easily withstand the broad distributed friction of cartons vibrating against one another in a master case.
• 13:26
  SPEAKER_01: Exactly.
• 13:27
  SPEAKER_01: That standard clear varnish turned out to be incredibly resilient.
• 13:30
  SPEAKER_02: So that answers the transit question, but what about the processing equipment at Opella's own facilities?
• 13:35
  SPEAKER_01: The packaging line.
• 13:36
  SPEAKER_02: Yeah, because we know they utilize high-speed cartoners and automated case erectors to actually get the rollerball into the folding carton and packed for shipping.
• 13:46
  SPEAKER_02: Usually, introducing a functional coating means you have to tweak all the guides and rails to prevent scuffing.
• 13:51
  SPEAKER_01: The durability of the cured varnish meant absolutely no retrofits were necessary on Opella's end either.
• 13:57
  SPEAKER_01: The folding cartons feed and run smoothly right through their existing cartoning and case erecting equipment.
• 14:02
  SPEAKER_01: The machinery treats the substrate exactly like a standard unscented paperboard carton.
• 14:07
  SPEAKER_02: That is fantastic.
• 14:08
  SPEAKER_02: So there was no drop in line speed and no loss of scent from the mechanical handling.
• 14:12
  SPEAKER_01: None whatsoever.
• 14:13
  SPEAKER_02: Let's pivot to the regulatory requirements for a second.
• 14:17
  SPEAKER_02: Because operating in the over-the-counter pharmaceutical space means the packaging is fundamentally a legally binding document.
• 14:23
  SPEAKER_01: Oh, it absolutely is.
• 14:24
  SPEAKER_02: You have the drug facts, the active ingredient percentages, the warning panels, and these are rigidly enforced by the FDA.
• 14:31
  SPEAKER_02: When you start applying functional interactive coatings to a folding carton, there is always a massive risk of obscuring that critical regulatory text.
• 14:40
  SPEAKER_01: And that's exactly why the transparency of this solution was a primary factor in its selection.
• 14:45
  SPEAKER_02: Aaron Powell Because the varnish is clear.
• 14:46
  SPEAKER_01: Yes.
• 14:47
  SPEAKER_01: Because the Sandosphere technology is suspended in a standard, clear, matte varnish, it cures completely transparent.
• 14:55
  SPEAKER_01: It does not alter or obscure the contrast of the printed ink beneath it at all.
• 15:00
  SPEAKER_02: Aaron Powell Oh, so a Pella can print their consumer call to action like a scratch and sniff text right next to an icon of a lime or an orange, lay the clear functional varnish directly over it, and the FDA mandated drug facts on the back and side panels remain perfectly legible.
• 15:14
  SPEAKER_01: Exactly.
• 15:14
  SPEAKER_01: And from a regulatory perspective, the FDA views this merely as a cosmetic claim because it does not interfere with the required medical information in any way.
• 15:23
  SPEAKER_02: That's brilliant.
• 15:24
  SPEAKER_02: Now we touched on Opel's status as a certified B Corp earlier and how that completely ruled out the use of pressure-sensitive labels.
• 15:32
  SPEAKER_02: How did this varnish solution actually perform when it came to the end-of-life metrics for the packaging?
• 15:38
  SPEAKER_01: It performed flawlessly, honestly, because chemically it remains a standard printing varnish.
• 15:44
  SPEAKER_01: When a folding carton utilizing this technology enters the recycling stream, it easily passes standard repulpability metrics.
• 15:52
  SPEAKER_02: Whereas mixed material stickers tend to gum up the screens and filters at paper mills, right?
• 15:56
  SPEAKER_01: Yeah, and that often leads to the entire carton being rejected and sent straight to a landfill.
• 16:01
  SPEAKER_02: Which is exactly what a B Corp wants to avoid.
• 16:03
  SPEAKER_01: Exactly.
• 16:04
  SPEAKER_01: But the scented varnish just breaks down naturally during the pulping process, ensuring the paperboard carton remains 100% recyclable.
• 16:12
  SPEAKER_01: For a B Corp sustainability team, achieving this sensory functionality without sacrificing the end-of-life recyclability is a massive achievement.
• 16:20
  SPEAKER_02: So the final variable we really need to examine here is shelf life.
• 16:23
  SPEAKER_02: A topical pain relief roll-on has a completely different supply chain lifecycle than, say, a perishable food item.
• 16:31
  SPEAKER_01: Oh, vastly different.
• 16:32
  SPEAKER_02: Because this product might sit in a distribution warehouse for three months, sit on a retail shelf for another two months, and then live in a consumer's gym bag for over a year.
• 16:41
  SPEAKER_01: And Opella engineers their product formulations for a minimum two-year expiry.
• 16:47
  SPEAKER_01: So the functional packaging has to demonstrate identical endurance.
• 16:50
  SPEAKER_02: Does it actually last that long?
• 16:52
  SPEAKER_01: It does.
• 16:52
  SPEAKER_01: Heidi Graham confirmed that they have sample cartons in their testing facility that are well over a year old right now.
• 16:58
  SPEAKER_01: Wow.
• 16:58
  SPEAKER_01: And when subjected to a scratch test today, the bloom profile is just as robust and potent as the day the carton came off the flexographic press.
• 17:07
  SPEAKER_01: The chemical stability of the encapsulated oil inside that cured varnish matrix is incredibly resilient over time.
• 17:14
  SPEAKER_02: So what does this all mean?
• 17:15
  SPEAKER_02: If we synthesize all these operational details, Opella and their converting partners essentially engineered a masterclass in cross-disciplinary packaging.
• 17:23
  SPEAKER_01: It really did.
• 17:24
  SPEAKER_02: They integrated a highly interactive mechanical sensory feature directly onto the substrate of a folding carton.
• 17:31
  SPEAKER_02: And they achieved this without incurring capex for new coating heads, without sacrificing line speeds on their automated cartners, without compromising the rigid FDA regulatory panels, and while maintaining 100% palpability.
• 17:47
  SPEAKER_01: If we connect this to the bigger picture, it shows that bridging deep chemical innovation, like the micro vault encapsulation from Centosphere, with legacy industrial machinery like a standard flexo press and an embosser can seamlessly solve behavioral consumer challenges at the retail shelf.
• 18:02
  SPEAKER_02: They didn't force a mechanical solution to a behavioral problem.
• 18:06
  SPEAKER_01: Exactly.
• 18:06
  SPEAKER_01: They recognized that they didn't need to reinvent the heavy machinery of the printing press.
• 18:10
  SPEAKER_01: They simply needed to reinvent the chemistry of the fluid running through it.
• 18:14
  SPEAKER_02: So to quickly recap this technical journey for you, Opella faced a critical sampling dilemma with the launch of their Revive and Recovery line.
• 18:22
  SPEAKER_02: They engineered a solution by taking authentic raw fragrance oil, microencapsulating it into load-bearing polymer shells, and suspending those shells into a standard clear flexo varnish.
• 18:34
  SPEAKER_01: And then, through meticulous mechanical calibration, they balanced the acute pressure of the embossing dyes to prevent premature fracturing.
• 18:43
  SPEAKER_02: Which resulted in a folding carton that withstands the lateral sheer forces of the supply chain, runs flawlessly on high-speed equipment, protects the vital drug facts, and meets strict B Corp recycling standards.
• 18:54
  SPEAKER_01: And this successful integration really forces you to look at the horizon of secondary packaging.
• 18:59
  SPEAKER_01: So secondary packaging is increasingly required to do the heavy lifting of consumer engagement right at the retail shelf.
• 19:04
  SPEAKER_01: The applications for microencapsulation technology are just vast.
• 19:08
  SPEAKER_01: We now know we can embed highly durable, friction-activated aromatic profiles seamlessly into a folding carton's varnish.
• 19:15
  SPEAKER_01: So the logical progression is exploring other sensory triggers.
• 19:18
  SPEAKER_03: Oh, like what?
• 19:19
  SPEAKER_01: Could future paperboard cartons incorporate temperature reactive microcapsules?
• 19:23
  SPEAKER_02: Wait, really?
• 19:24
  SPEAKER_02: Like feeling the temperature change?
• 19:26
  SPEAKER_01: Yes.
• 19:27
  SPEAKER_01: It is entirely plausible to engineer a folding carton that releases a localized cooling sensation right onto a consumer's fingertips merely from the ambient thermal transfer of them picking it up in the aisle.
• 19:39
