US-based Coldpack has produced a new packaging structure called the AirLiner for candies, with barrier films made by Danafilms.
AirLiner is an inflatable, insulating plastic liner that offers temperature control and protection from rough handling that delicate food items require. It protects the candies from warmer temperatures or from becoming brittle in colder climes as well.
The new AirLiner has multiple layers of film, which form air-filled baffles to insulate a shipment’s contents and the number of baffles is directly related to the structure’s thermal characteristics, and acts as much as a cushion as a temperature control.
The AirLiner offers similar insulation and cushioning properties compared to its rigid foam counterparts and the inbound freight savings, combined with raw materials savings as compared to foam, help the candy maker to realize a 96% improvement on its packaging’s carbon footprint.
Danafilms sales manager Steve Crimmin said the new structure is an extension of void-fill packaging, and by using less material versus styrofoam, the company is making the most of sustainability.
"The finished film uses metallizing technology to provide a thin, reflective barrier, which refracts heat or cold back into the package and does not let it dissipate out," Crimmin said.
