Background
The hard transparent PVC sheet is prepared by adding impact modifier and stabilizer to PVC, mixing, plasticizing, and rolling. It can be made into thin-wall transparent container by using thermal forming process or used for vacuum plastic-sucking package, and is an excellent packaging material and decorative material.
