  Many  stretch film manufacturers  will have many bubbles in the stretch film during production, which has a great impact on the quality of the product. The quality inspection of stretch film with bubbles is definitely unqualified and cannot be sold as a finished product. This will not only waste production The material will also waste a lot of time, so avoid this situation during the production process. In order to avoid the occurrence of these situations, it is necessary to find out the cause of the bubbles. Through research on them, Zhiteng stretch film manufacturers have found some solutions. Let me introduce you to everyone and welcome everyone to discuss them together. First, select the appropriate ink to increase the coating amount Appropriate ink can be selected according to needs, increase the coating amount to strengthen the wetting of the glue to the film, and improve the defects of poor local sizing. This can increase the temperature and pressure of the axis,...

  At present,  PE stretch film   is widely used in the logistics industry and is a convenient and environmentally friendly packaging material. PE stretch film has a wide range of uses, and can also be used for damage protection and purification during food packaging, maintenance, transportation, storage, processing and application. pe stretch film production materials: 1. The pe stretched film is made by co-extruding polypropylene particles into a sheet, which is then stretched in the longitudinal and transverse directions. The transparency of polyethylene decreases with increasing crystallinity. Under a certain degree of crystallinity, transparency increases with increasing molecular weight. The melting point of high-density polyethylene is 132-135°C, while the melting point of low-density polyethylene is lower (112°C) and the scale is wider. 2. PE stretched film is a kind of stretched film made of polyethylene terephthalate as raw material, made into thick sheet by extr...

  PE stretch film  is a kind of film with relatively good shrinkage performance, which plays a very important role in product packaging in many fields, but there will be a problem in the production process of this product, that is, the shrinkage is relatively large. Although this problem does not occur frequently, once it occurs, it will have a greater impact on the use of the product. Therefore, in solving the problem of excessive shrinkage of the PE stretch film, we must first know what causes it. Reasons for large shrinkage of PE stretch film: The raw material of the OE stretch film is an amorphous polymer. When it receives a tensile force greater than its stretch within a certain temperature range, the rescue will produce plastic elongation, resulting in deformation. In the process of deformation, the polymer structural units begin to orient due to stretching. As the degree of orientation increases, the force between the macromolecules increases, resulting in an increase i...
