Comparison of characteristics of POF heat shrinkable film and PVC film

POF means heat shrinkable film. The full name of POF is called multi-layer co-extruded polyolefin heat shrinkable film. It uses linear low-density polyethylene as the middle layer (LLDPE) and co-polypropylene (PP) as the inner and outer layers. It is formed by plasticizing and extruding from the machine, and then undergoing special processes such as die forming and film bubble inflation. Its English name is Polyole fin. Generally speaking, heat shrinkable film is POF, or Polyole fin Shrink Film. 1. For frozen food, it has a longer storage time. 2. Flexibility and strong stretchability. 3. With self-adhesive function. 4. It has extremely high gloss and transparency. 5. At low temperature, it shortens rapidly. 6. Excellent sealing at high speed. Because of its strong bonding ability, shrink film is used in craft and machine surroundings. 7.

Good flexibility: avoid The packaged items are impacted by external forces and play a role in protecting the packaged items. The packaging cost is low, and the quality is cheap. 9. High shrinkage rate: The shrinkage rate of heat shrinkable film can reach up to 75%, which is suitable for the collection of multiple items Packaging, convenient transportation. And can meet the requirements of different commodities for shrinkage. 10. Strong cold resistance: Even under the condition of minus 50 degrees Celsius, its physical properties will not change, so it is suitable for the packaging and transportation of frozen food. PVC heat shrinkable film is suitable for the packaging needs of products in various industries. It can be used for single or small collection packaging, or large tray packaging. It can be used for stationery, toys, textiles, paper products, beverages, medicine, Heat-shrink packaging for tongue-and-groove flooring, hardware appliances, etc. Heat shrinkable film is the most widely used and rapidly developing new environmentally friendly shrink film in the real world. It has high transparency, high shrinkage, high toughness, high heat sealing performance, antistatic, excellent cold resistance, safe and reliable soft shrinkage membrane. It is widely used in outer packaging and collective packaging in various industries such as food, cosmetics, gifts, medicine, stationery, toys, audio-visual products, electronics, plastic hardware, daily necessities, etc. It is suitable for semi-automatic and fully automatic packaging machines.
