Weishan Zhengshuai Packaging Technology Co., Ltd.
Heat shrinkable films can be seen everywhere in life, small batteries, fruits, food packaging, large trays, more than ten meters of equipment, packaging need to use it, because heat shrinkable film is easy to use, economical and practical, has become us Packaging materials everywhere in life. There are a variety of products on the market. What if you choose a heat shrink film that suits you?
In general, the more common shrink films on the market are divided into several categories: PE shrink film, PVC shrink film, POF shrink film, different materials, different performance, the use will vary depending on the material, and different shrink films are used in different places different.
PE heat shrinkable film has good flexibility, impact resistance, large shrinkage rate, relatively insufficient transparency, pe shrinkage rate: horizontal: 15% --- 30%, vertical: 50% ---- 70%, shrinking Temperature: 120 擄 --- 180 擄, thickness can be 0.02-0.12mm, suitable for various beverages such as wine, cans, mineral water, etc., as well as heat shrink packaging for some large equipment.
POF heat shrinkable film has high transparency, good shrinking quality, high strength, and can well protect the packaged products, but the thickness of pof is limited. The thickest can only be 3 wires, and the thickness range is 0.012-0.03mm. Therefore, it is not suitable for the packaging of heavy products, and it is suitable for packaging of daily necessities such as food, cosmetics, gift stationery, and toys. In addition, there is also a requirement for the temperature of the shrinking machine. Generally, the shrinking temperature of 1.5 silk is required to be 140-150 degrees, and the shrinking temperature of 2 wires is more than 170 degrees. The shrinkage effect is better.
