by:HYF     2021-03-02
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 out of the machine, and then undergoing special processes such as die forming and film bubble inflation.   1. For frozen foods, the storage time is longer.   2. Flexibility and strong stretchability.  3, with self-adhesive function.   4. It has extremely high gloss and transparency.   5. At low temperatures, it shortens quickly.  6. u200bu200bExcellent sealing at high speed. Shrink film has strong bonding ability, so it is used in craft wrapping and machine wrapping.   7, safe and non-toxic: the materials used in heat shrink film are all non-toxic, and it is the only certified green packaging material in the United States.   8, 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 low.    9. High shrinkage rate: The shrinkage rate of heat shrinkable film can reach 75%, which is suitable for multiple items. Packed together, easy to transport. 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 .Tag: p0f heat shrinkable film
