Mono-material conversion raises polyester content per pack
European packaging rules and American state recycling legislation both push brand owners off polyester and polyethylene laminate structures, because a mixed-polymer pack has no recycling stream that will accept it. Replacing the polyethylene sealant with heat-sealable polyester creates an all-polyester pack and increases BOPET content rather than simply moving volume between film suppliers. Around 11% of flexible packaging has converted. Commercially this is the only mechanism in the market that grows demand instead of redistributing it, and heat-sealable grades require capability that standard line configurations do not deliver. Brand owner deadlines are fixed rather than aspirational.
