How to solve the PE bag sticking problem

PE bags sticky solution measures. (1) control the ripening temperature to ensure that the smooth agent at high temperatures, especially high-temperature cooking bags, because RCPP originally smoothness is not good, it is difficult to control the friction coefficient after a long time ripening at high temperatures. (2) Ensure that the adhesive does not seep into the inner surface, otherwise it will affect the coefficient of friction of the substrate film surface, especially in the case of thin films and excessive corona treatment is more likely to occur such problems. (3) ensure that the film substrate itself smooth quality; if the smoothness of bad extrusion compound can not add smooth agent, extrusion PE film is very sticky, the coefficient of friction is large; I. PE bag PE is short for polyethylene, is a thermoplastic resin made of ethylene by polymerization. In industry, also includes copolymers of ethylene and a small amount of α-olefin; is a transparent plastic bags, can be used for clothing, bags, electronic products and other packaging. Second, PE bags Types According to the material: PE is divided into LDPE, LLDPE and HDPE, etc. According to the production process is divided into: PE flat pockets, self-sealing bags, chain bags, envelope bags, perforated bags, tote bags, zipper bags, PE film. 1, PE flat bag for the simplest production process, by the machine after blowing film, and then to the bag-making machine above the cut into a bag, the bottom seal. 2, self-sealing bags are blown by the machine with a bone strip, can be manually sealed. Different from the chain-locked bags, the two bags are generally easy to confuse. 3, chain-locked bags are made of PE film, plus 2 clip chain on top (this clip chain is a separate out) to make the bag, the bag generally has a relatively wide indentation on both sides, while the self-sealing bags are not. Self-sealing bags printed with fewer colors, while the clip chain bags can be printed with complex patterns. 4, envelope bag is like an envelope with a tongue, stick a strip of tape on the tongue, fold over the bag can be sealed. General clothing category with more. There are also courier bags is actually a kind of envelope bags. 5, perforated tote bag is a hole at the top of the flat pocket at the appropriate location to facilitate the lifting of the bag. 6, hand-held bags are to be added to the top of the bag plastic film strip, to facilitate the lifting of the bag, this process consumes labor, the cost is relatively high. 7、Zipper bag is to put a zipper chain on the bag closure and bring the zipper cap. 8, PE film is the machine blown out of the film is not made into a bag. Also divided into winding film and shrink film. 9, another PE material cling film can also be called PE bags, note that direct contact with food cling film must be used PE material (the other is generally PVC), the human body is safer. The difference: PVC cling film is stronger than PE cling film in terms of transparency, stretching and viscosity. PVC cling film has a black flame when burned with fire, black smoke, a pungent smell, no oil dripping, and will automatically go out after leaving the fire. PE cling film burns with a yellow flame, is odorless, drips oil, and can continue to burn after leaving the fire.
