PE/PE and PP/PP high-barrier structure comparison
PE/PE

Our main option. PE-based, high-barrier structures designed for recycling, suited to most dry food, pet food and snack applications.

PP/PP Premium

A premium option for demanding conditions. PP-based, high-barrier structures keep their barrier performance stable under high temperature and humidity. Higher cost, recommended for high-end products or applications where heat and humidity performance matters.

Recyclability notice

Recycling acceptance and collection methods vary by province, municipality and recycling program. A package described as “designed for recycling” has been developed with material compatibility in mind but may not be accepted in every local collection system.
