How thick is the POF shrink bag?

POF shrink bags have high transparency and good gloss, which can clearly display the appearance of the product, enhance sensory awareness, and reflect the product. Compliant with US FDA and USDA standards, all manufactured with environmentally friendly materials, it is an eco-friendly packaging material that can package food and can be recycled and reused. Do you know how thick the POF shrink bag is?

1. POF shrink bags have a high shrinkage rate of up to 75%, good flexibility, and can be used to package any shape of product. Moreover, the three-layer co extruded film treated with special technology has controllable shrinkage force, meeting the requirements of different product packaging for shrinkage force. Good sealing performance and high strength, suitable for manual, semi-automatic, and high-speed fully automatic packaging.

2. The thickness that POF heat shrink film can provide depends on your own needs. Generally, POF shrink bag manufacturers can provide POF heat shrink film in specifications such as 10 μ, 12 μ, 15 μ, 19 μ, 25 μ, 30 μ, and 38 μ. The thickness and raw materials of POF heat shrink film determine the shrinkage temperature and effect.

3. The optimal shrinkage temperature for POF shrink film with a thickness of 0.015mm (1.5 threads) is around 150 ℃, and the higher the thickness, the higher the required shrinkage temperature. The shrinkage temperature for a 0.02mm (2 threads) shrink film is even higher, around 170 ℃. Speed and temperature are also directly proportional. The faster the speed, the higher the temperature. Temperature and speed should be controlled according to actual operation to achieve better results.
