Xiamen Guanhua is one of China POF Heat Shrink Wrap manufacturers, suppliers and exporters.

POF Heat Shrink Wrap has the characteristics of high surface gloss, good toughness, high tear strength, uniform thermal shrinkage and suitable for automatic high-speed packaging. It is a replacement of traditional PVC thermal shrink film. POF is the meaning of heat shrinkable film, the full name of POF multi-layer co-extruded polyolefin heat shrinkable film, it is linear low-density polyethylene as an intermediate layer (LLDPE), polypropylene (pp) as the inner and outer layers, through three extruders plasticized extrusion, and then through the die molding, film bubble blowing and other special processes.

POF Heat Shrink Wrap packaging is one of the most advanced packaging methods in the market, the use of shrink film wrapped in the product or packaging outside, after heating the shrink film wrapped the product or packaging, fully display the appearance of the item, improve the product's marketability, increase the sense of beauty and value. At the same time, the packaged items can be sealed, moisture-proof, anti-pollution, and protect the goods from external impact, with a certain cushioning, especially when packaging fragile products, to prevent the utensils from flying apart when broken. In addition, it can reduce the possibility of the product being dismantled and stolen.

Principle :

The production of POF Heat Shrink Wrap is usually produced by extrusion blow molding or extrusion casting method to produce a thick film, and then longitudinal and transverse stretching at a high elastic temperature above the softening temperature and below the melting temperature, or only in one direction of the tensile orientation, and the other direction is not stretched, the former is called biaxial tensile shrink film, and the latter is called unidirectional shrink film. When used, the shrinkage force is reliable when it is greater than the tensile temperature or close to the tensile temperature to bind the packaged goods.

POF Heat Shrink Wrap Advantages:

1. Beautiful appearance, close to the goods, so it is also called body packaging, suitable for a variety of different shapes of goods packaging.

2. Good protection, if you combine the inner packaging of shrink packaging with the transportation packaging hanging on the outer packaging, you can have better protection.

3. Good stability, the product will not stagger in the packaging film.

4. Good transparency, customers can directly see the product content.
