Do You Know What's Inside?
CelluLiner is an innovative paper-based insulated packaging material that’s curbside recyclable and protects shipments for up to 72 hours. Our paper material is compostable and bio-degradable.
Introducing our innovative paper insulated box liner that’s made of 100% curbside recyclable materials and designed to protect frozen and refrigerated shipments between 48-72 hours.
Made of an advanced multi-layered paper material that’s designed for maximum insulating performance, these paper insulated packaging products can be fully collapsed to a flat format for space and cost savings during transit and storage.
Made with 100% biodegradable cellulose insulation panels and outer casing, CelluLiner contains thousands of small air pockets per cm3 that substantially slow heat transfer, while the outer shell is also naturally insulating. The combination of these materials results in an insulating liner that provides protection against even the most extreme ambient conditions.
Our high-performance paper insulated box liner comes as two separate three-sided panels that interlock to form a box shape. The panels can be placed into a box shape in just a few seconds, after which they are ready to be loaded with your temperature-sensitive goods.
After use, the panels can be conveniently flattened and placed in a curbside recycling bin or used for compost.
Our CelluLiner insulated box liner is very consumer oriented making it a perfect option for Meal Kit Delivery
Not all paper packaging products are the same
Unlike some paper packaging products that use low quality, non-recyclable material such as newsprint and cornstarch, at IPC we only use post-consumer paper materials that are valuable to recycling companies.
