What chips packaging called?
A typical potato chip bag is made up of multiple layers of polymer materials: Biaxially Oriented Polypropylene (BOPP) on the inside, low-density polyethylene (LDPE) in the middle, another middle layer of BOPP, and an outer layer of Surlyn®, a thermoplastic resin. Each layer performs a specific function.
What type of packaging is used for potato chips?
A typical potato chips bag is made up of multiple layers of polymer materials. The materials are Biaxially Oriented Polypropylene (BOPP) on the inside, low-density polyethene (LDPE) and BOPP in the middle, and an outer layer of Surlyn®, a thermoplastic resin.
