Plastrela creates recyclable mono-material polyethylene pet food standup pouch
Plastrela, a leading converter based in Brazil, wanted to create a snack size pet food standup pouch (SUP) for its customer, brand owner Adimax, that can be easier to recycle than traditional SUP structures. The challenge was to replace a conventional multi-layer structure consisting of a polyethylene terephthalate (PET) substrate and a polyethylene (PE) sealant with a new mono-material** PE//PE solution that could be easier to recycle.
“The biggest challenge in changing the SUP packaging from a transparent PET structure laminated with PE film into a PE//PE structure was the formatting and machinability of the film in the cutting-welding equipment,” said Chih Ming, Technical Manager, Plastrela. “Based on our experience, the production of SUP packaging requires a high sealing temperature in the sealing bar and as a result polyester film is usually used in the packaging structure.”
