Information

PVC wire winding film is widely used in the field of its small volume and high viscosity, convenient for wire winding and packaging of scattered goods in a whole set instead of small storage box. Because it can reduce the cost of bulk goods transportation and packaging by more than 30%, it is widely used in the whole package of hardware, mineral, chemical industry, medicine, food, machinery and other products; In the field of warehouse storage, many foreign countries also use the packaging of stretch wound film tray for three-dimensional storage and transportation, so as to save space and occupy land.

PVC wire winding film is a new packaging material, which is of ultra thin, strong and tough, transparent, self-adhesive and low temperature resistant. It is an ideal packing material, especially suitable for packaging chemicals, electronic parts, building materials products, rubber, low brick, tile, screws, wallpaper, leather, glass fiber, non-woven fabric, paper roll, wire and wire, Good viscosity makes the outer packing film and layer stick together to make the goods firm. There are two methods to obtain the viscosity: one is to add PIB or its master material to the polymer; The other is mixing VLDPE PIB as translucent viscous liquid. Special equipment or equipment modification is required for direct addition. Generally, PIB master material is used. PIB has a process of moving out, generally for three days. In addition, it is also affected by temperature. When the temperature is high, viscosity is strong, and it is not too sticky when the temperature is low, and the viscosity is greatly reduced after stretching, Therefore, the film of finished product is best stored in a certain temperature range (it is suggested that the storage temperature is 15 ℃ ~ 25 ℃) mixed with VLDPE, which is slightly poor in viscosity. However, there is no special requirement for the equipment. The viscosity is relatively stable and not controlled by time, but also affected by temperature. When the temperature is higher than 30 ℃, the viscosity is slightly worse than 15 ℃, and the LLDPE content of adhesive layer can be adjusted, To achieve the required viscosity.
