The merchants who know know that the POF contraction membrane is mainly used for products that are used for packaging rules and irregular shapes. Because of its non -toxic and environmental protection, high transparency, high contraction rate, good thermal sealing performance, high luster, strong toughness, tear resistance,, tearing, and The characteristics of thermal contraction are uniform and suitable for full -automatic high -speed packaging, which are widely loved by many industries. So what kind of material is POF shrinking film, what is its shrinking temperature? Let me explain it below!
POF shrink film material
The full name of the POF contraction membrane is called multi -layer co -squeezed polylefin thermal contraction membrane. It is processed by special processes such as formulating and film bubble swelling.
How much is the shrinking temperature of POF shrinking membrane?
The actual heat -making effect of POF contraction membrane is also different. It is about 0.015mm in about 170 ° C (1, for example, the weather is relatively cold now, and the temperature is gradually adjusted to the best. To achieve the best contraction effect. There are different manufacturers of different manufacturers. The optimal shrinkage temperature of the POF contraction membrane with different heat components of the shrinkage machine is about 150 ° C. Some may not reach the adjustment temperature. The required shrinkage temperature is higher, the temperature of the temperature of the thermal shrinking machine is different in different seasons. The greater the required shrinkage temperature, the higher the thickness, 0, and the contraction temperature should be appropriately increased. It is worth noting that this should be paid attention to when the actual contraction
The main characteristics of POF shrinking membrane
1. High transparency and good gloss, you can clearly display the appearance of the product, improve the sense of sense, and reflect the high level.
2. The contraction rate is large, up to 75%, and the flexibility is good. It can be packaged on any shape of the product, and the contraction of the three -layer co -squeezing film of the special process can be controlled to meet the contraction of different commodities packaging. Require.
3. Welding performance is good, high strength, suitable for manual, semi -automatic and high -speed fully automatic packaging.
4. Good cold resistance, which can be kept flexible at -50 ° C without crisp cracking. It is suitable for storage and transportation in cold environments.
5. Environmental protection is non -toxic, which meets the US FDA and USDA standards, and can be packed food.
