Stretch Film for Machines

It lowers labor intensity, has great adaptability, high efficiency, low consumption, and is appropriate for quick transit or storage.

A microprocessor is used as the control core of the fully automatic tray-type stretch wrapping film packaging machine. It can automatically perform the wrapping film packaging activities necessary to meet different process requirements using the packaging materials. Its features include dependable use, easy operation, and steady performance. The film packaging machine is appropriate for packing large pallets and transporting bulk items in containers. often utilized in hardware tools and glass items.

Sticky Control Edit Broadcast：

Good viscosity makes the packaging film layers and layers outside the goods stick together to make the goods firm. There are two main ways to obtain the viscosity: one is to add PIB or its masterbatch to the polymer; the other is to blend VLDPE . PIB is a translucent viscous liquid. Direct addition requires special equipment or equipment modification. Generally, PIB masterbatch is used. There is a process for PIB to move out, which usually takes three days. In addition, it is also affected by temperature. When the temperature is high, the viscosity is strong; when the temperature is low, it is not too sticky, and the viscosity is greatly reduced after stretching. Therefore, it is best to store the finished film within a certain temperature range (recommended storage temperature is 15 ℃ ~ 25 ℃). Blending VLDPE, the viscosity is slightly poor, but there is no special requirement for the equipment, the viscosity is relatively stable, not controlled by time, but also affected by temperature, when the temperature is higher than 30 ℃, it is relatively viscous, and when the temperature is lower than 15 ℃, the viscosity is slightly worse, and it can be The desired viscosity is achieved by adjusting the amount of LLDPE in the adhesive layer. This method is mostly used in three-layer co-extrusion.
