Material selection is based on your specific application and ultimately where your product is to be shipped. PVC material holds several advantages over its PET counterpart. These include superior resistance to heat and flames and better overall sealing capabilities; however, many packaging industry insiders regard PVC to be an environmental concern. While the potential hazard PVC may present to the environment has been largely unsubstantiated, PET material holds an advantage in the fact that it is more widely accepted, especially in the European community, than its PVC counterpart. At Universal Protective Packaging, Inc.(UPPI), we offer packaging made from both PVC and PET materials and can make an accepted package for your product no matter where it may be headed.
