USE Polyvinyl chloride heat shrink packaging film is mainly applied to outside packaging of audio-video products, toys, magazines, glasswares, high-quality floor boards, dry battery and so on.. Feature: Polyvinyl chloride heat shrink packaging film is characterized by high strength, nice transparency, waterproof, damp-proof, high antipollution and sound insulation property. Being a packaging material, it cannot only simplify the packaging technology and reduce the packaging volume, but also can display the color and design of materials. There fore it is widely applied to packaging commodities. Main specification of the production line: 1. Raw Material use PVC granule or PVC powder 2. Screw Dia 75mm 3.
