Application case

A new packaging that combines layers of coated bio-material and compostable paper

Coathink™ provides the high-performance barrier to oxygen and moisture.

  •  OTR < 0.5 cc/m2 24h | WVTR < 1.8 g/ m2 24h
  •  Paper outer layer
  •  Certified compostable according to EN13432
  •  High quality printing

At the heart of the high-barrier packaging is SAES Coated Films’ BXM product, a heat-sealable compostable film coated and metallized with patented Coathink® technology. The film is used as an inner layer and is laminated with an outer layer of compostable paper, giving consumers the distinctive touch&feel of a natural material.

Thanks to Coathink™, the packaging has exceptional barrier properties that meet the requirements for the protection of long shelf-life food products:

  • OTR (23 °C, 0% RH) below 0,5 cc/m2 24h
  • WVTR (22°C, 50% RH) below 0,5 g/m24h.

The packaging has received certification according to EN 13432 for industrial compostability, and after use can be safely and conveniently recovered in the organic waste bin.

Want to learn more about compostable packaging?

  • BXM film is OK Compost INDUSTRIAL certified.

The OK Compost certifications guarantee the compliance of packaging with reference standards in terms of biodegradability and industrial compostability.

The certificate is issued by an independent control body to those packaging products that prove to be compostable and suitable for organic recycling. The certification constitutes a documented and recognizable guarantee able to orient the industry and consumers towards more responsible choices.

To obtain OK COMPOST certification, the product must meet the strict requirements of EN 13432 and be subjected to accurate tests of chemical analysis, biodegradability, disintegration and ecotoxicity.
