How to solve the PE bag sticking problem

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.

What kind of bags are pe bags?

What kind of bags are pe bags?

pe bags are polyethylene bags. In industry, also includes copolymers of ethylene and a small amount of alpha-olefin, is a transparent plastic bags, can be used for clothing, bags, electronic products and other packaging. Polyethylene according to the polymerization method, molecular weight high and low, chain structure of different, divided into high density polyethylene, low density polyethylene and linear low density polyethylene. The advantages of pe bags: 1、Good sealing. Experimental data show that the new OPP film is more than double the sealing of its traditional film, thus making its products moisturizing, freshness and longer preservation time. 2、Strong anti-counterfeiting. The synthesis technology and special printing technology used in the new film have a high technological content, and only Germany and Japan have mastered this technology, so it is impossible to imitate the production, which provides a strong guarantee for the anti-counterfeiting of goods. 3、The raw materials used in the new OPP film are degradable materials, so it is fully in line with the international standards in terms of environmental protection.

Do new food undershirt bags have a shelf life?

Do new food undershirt bags have a shelf life?

Food bags are normally valid for 3-5 years, depending on the extent of your food bags, and its quality is different, is probably so long to keep time. Undershirt bags are very widely used in our lives, whether in supermarkets or wholesale markets we can see their silhouettes, which in a large part of Chengdu are because the material of this plastic bag has a very good performance.

Undershirt bag making bag crack bottom how to do

1, first of all, the bottom of the undershirt bag bag-making process when the jump tear size inconsistencies, you need to deal with in a timely manner. 2, followed by the size of the rift is affected by the nature of the material, equipment conditions, operating skills and other factors, the need to analyze the specific causes. 3, and finally, if the problem is the material, you can replace the material of better quality; if the equipment condition caused by the need for timely repair or replacement of equipment; if the problem is the operating skills, you need to train or adjust the operating methods.

Polyethylene material for making undershirt bags

Polyethylene material for making undershirt bags

The polyethylene material for undershirt bags is milky white before processing, but after some primary processing, its form will be changed, for example, the material is translucent in the thin section state, which is also the pre-working state of plastic bag forming. 　　The polyethylene material used to make the undershirt bags has a very good durability, and it can also have its own characteristics for life and chemical products within a certain Chengdu and range. As we can find in the process of use, the material of the undershirt bag has a very good non-hygroscopic properties, and can well prevent water vapor, which also greatly extended its field of use. Very special is that the material for making the undershirt bag has very good electrical properties, while its dielectric strength of insulation is also very high. It is worth mentioning that this material can be well used in different temperatures, which also improves the ability to use the undershirt bag in a large number of Chengdu.

Introduction of the material of undershirt bag material

Introduction of the material of undershirt bag material

What we all know is that HDPE material is a very high density material, and it also happens to be one of the main materials for making undershirt bags. This polyethylene material (HDPE) has a very good hardness, although there are certain difficulties and strict technical requirements in the production process, but the product has very good properties, and very good performance. 　　HDPE material itself has a very good stability, so this also to a large extent to ensure the use of plastic bags in the case. The material used to make the undershirt is a highly crystalline and non-polar thermoplastic resin, which is very safe and convenient for the user, both in the storage and production phases of the material.
