zhiteng stretch film

  Nowadays, the reasons why many companies choose   stretch film   are mostly because of the shrinkage and fixity of stretch film. Because the characteristics of stretch film can be used in the packaging of small items, the shrinkage force of stretch film after stretching is reduced.  The product is wrapped and packaged so that the packaged product looks compact and does not take up too much space, which can effectively prevent mutual misalignment and movement during transportation. The production of stretched film requires heat treatment, so how should the stretched film be heat treated? In the heat treatment process of the stretched film, the workpiece is deformed by cold plasticity, resulting in cold hardening, which will reduce the plasticity of the stretched film, but increase the deformation resistance and hardness. In addition, the mold design is unreasonable, which requires Perform intermediate annealing to soften the metal and restore its plasticity. Note: I...

  With the continuous growth of the stretch film market, more and more products are packaged with stretch film. At present, stretch films on the market mainly use LLDPE raw materials.  Both machine stretch film and  hand stretch film  have good tensile properties , strong shrinkage and high transparency, good puncture resistance, good self-adhesion and low unit consumption. Whether it is used for collective product packaging or pallet packaging of goods, it can achieve the purpose of moisture, dust, and waterproof, reducing labor, improving efficiency and reducing costs. Generally speaking, there are two types of stretch films on the market, machine stretch films and hand stretch films. 1. Machine-use stretch film is to put the objects to be wrapped in the middle of the turntable. Through the pneumatic turntable motor, the turntable is driven to rotate, and the stretched film is naturally and evenly wrapped on the surface of the object. At the same time, the lifting ...

  As a kind of packaging material, many people don’t know how to cut it. How to cut is the tangential method to ensure the integrity of the   pe stretch film . How should our PE stretch film be cut when cutting? A: First of all, there are two ways to cut pe stretch film, one is manual cutting, and the other is saw cutting. The main tool for manual cutting is manual hacksaw to cut pe stretch film. B: The cutting of pe stretch film sawing machine is done on the sawing machine, because the sawing machine itself is equipped with high-speed steel saw blades. Some construction sites often use some easy-to-carry electric sawing machines and other machines, but Each machine has a defined thickness or diameter. C: The pressure test of the pe stretch film itself includes two kinds of pressure on the molded product and the pressure on the film channel system. Then the pressure on the film product is to check the pressure resistance and tightness of the pe stretch film itself, which ...
