  Stretch film   is widely used in industrial production. The most effective protection of stretch film for products is its most basic function. If stretch film does not have a reliable maintenance function for packaged goods, then it will lose its application as a packaging product. The value of this is a failure in the selection of materials. The maintenance function of stretch film for goods is also diverse. Different commodities have different packaging methods, and the focus on the maintenance function of stretch film is different. Let me introduce the main functions of stretch film: 1. Good mechanical maintenance effect Good mechanical maintenance effect, avoiding the leakage of the goods in the package or the damage or contamination of the goods caused by foreign matter entering the package, which can directly reflect the mechanical maintenance function of the stretch film. The higher the strength of the stretch film, the stronger the tear resistance. The greater the pu...

  Many users who have used stretch film should know that the quality of a stretch film directly affects the user’s experience. If the quality of the stretch film is not good, the packaged product will not be firm, so that it will be transported Damage will occur during the process. What are the factors that affect the quality of  stretch wrapping  film ? Today Joypack will give you a detailed answer: In different industries, stretched film has also been widely used, usually in the three-layer co-extrusion casting process. Use imported linear low-density polyethylene as the production material. The product can reach the leading level in all indicators, and has good stretch film ability and transparency, and also has strong tear resistance. It can also be self-adhesive under normal temperature. Therefore, The scope of application is extremely wide. The use of stretch film to package products can minimize the cost and enable the use of box packaging in batches. This virtuall...

  The polyethylene blend of   pe stretch film   should be hot-filled at 100 degrees Celsius, and even if it does not break under the tension of the filling, it will have a larger stretch deformation. Usually, the liquid filling film has high temperature resistance and good strength co-extruded stretch film, such as: Although the inner layer of adhesive resin is still PE material, the outer layer is nylon film, which has high heat resistance. The strength is high, and the fuse machine cannot be used to fuse and fuse the bag. The PP/EVA/PE co-extruded film can be fused, but the heat sealing temperature is between 190-200 degrees Celsius, and the thickness should be appropriately increased to 80-90μm to ensure the strength of the composite film. Another reason for the breakage of the stretch film is caused by excessive tension. The solution is to reduce the tension of the packaging machine. In fact, after sterilization at 100 degrees Celsius, properly cool it down and reduce...

 J oypack is a professional   stretch film manufacturer , providing high-quality stretch film products and competitive prices. After we buy the stretch film, we need to store it when it is not used for a long time. However, many times we find that some stretch films have turned from the original transparent color to yellow. What is the reason? Strictly speaking, the stretch film has only two colors, colorless and colored. The main reason for the light yellow is DOV, color masterbatch and other additives or processing technology changes. If the color is light, the stretch rate and self-adhesiveness are not affected. If it affects, you can continue to use it. If the color is unnatural, the quality will be poor. The stretch film technology has developed to now have been very mature, some manufacturers will try to change the formula to produce stretch film with different properties. It is mainly reflected in three aspects: color, stretch rate and self-adhesiveness. A single color ...
