Renewliner: Curbside Insulated Shipping System Made From PET Part 2

Welcome to part 2 of our series on PET. You can catch up on part 1 here.

Once we investigated the environmental benefits of PET, we moved on to identify some of the characteristics we knew our customers required: thermal performance, food contact safety, cushioning and protection, and, of course, aesthetics.

PET is used in various insulation applications worldwide, and after conducting testing in our lab we were able to quickly confirm Renewliner would be able to offer customers a solution that provides the thermal protection necessary to keep products unspoiled and within spec, even for transits exceeding 72 hours.

Because insulated packaging has a good possibility of coming in direct contact with foods and medications, we had to be sure that whatever material we settled on would be safe. PET is naturally inert and contains anti-bacterial properties, which is why it is used widely in direct food contact packaging products. PET is completely safe both for human and food contact.

When it comes to protecting delicate items, from medications and electronics to a perfectly ripe tomato, it was crucial to ensure Renewliner would protect them during an often-tough journey to the end consumer. PET contains cushioning capabilities that are unlike most other insulating materials, and we conducted real-world tests by sending out sample materials to national parcel carriers, all of which determined that it passed our crush test standards.

Finally, we understand the unboxing experience is an impactful moment. This is why we wanted Renewliner to “just look right” inside a box. PET not only looks fresh, it also looks professional, sanitary, and aesthetically pleasing.

It was a long research process, but we are confident that PET is the best material for a packaging solution that minimizes waste at all stages of the product lifecycle without sacrificing affordability, accessibility, or aesthetics. PET and Renewliner allows us to move toward a truly circular economy without the need to harvest any new materials, while also achieving the important goals associated with any high-quality packaging—which is why companies like L’Oréal, Nestle Waters, PepsiCo, and others are choosing PET solutions and investing into the PET closed loop circular economy.
