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?

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.

The main role of self-sealing bags

The main role of self-sealing bags 1、Freshness preservation: preserving fruits and vegetables, preventing dryness and locking deliciousness. 2、Freezing: freezing and thawing to ensure freshness and prevent string taste. 3, storage: home travel, easy to carry, easy to seal. 4, moisture: dry storage, moisture and humidity, isolate the odor. 5, classification: sorting, convenient storage, clean and sanitary. 6、Double-sided 5 silk self-sealing bags: generally used in the waterproof and moisture-proof role of product packaging, convenient and economic, disposable packaging supplies, such as: manuals and other documents. 7, double-sided 7 silk 9 silk self-sealing bags: mostly used in food preservation packaging, electronic product accessories and other product packaging, for example: preserves, peanuts, chargers headphone cable, etc. 8, double-sided 11 silk self-sealing bags: general household product classification, storage; hardware product accessories packaging, for example: clothes, toys, daily necessities, hardware screw accessories, etc. 9, double-sided 14 silk 16 silk 20 silk self-sealing bags: export products high-grade accessories refrigerated food packaging, for example: powder, chemicals, etc. Description of the thickness of 1 silk = 0.01mm (mm) double-sided thickness is the thickness of the two layers together, such as double-sided 20 silk, that is, double-sided 0.20mm (mm), single-sided 10 silk (0.1mm (mm)), the larger the number represents the thicker the thickness. Size of the description of the width (cm) * length (cm) * thickness (silk), for example: 8 * 12 * 5 silk, that is, 8 cm * 12 cm * double-sided 5 silk thick. Size is the outer size, the inner size needs to be in the length minus the part above the self-seal, usually 1cm-2.5cm, for example: the outer size is 8*12cm, the inner size is 8*10.5cm. The use of self-sealing bags to preserve tea benefits In daily life, most of our families have more or less stored some tea, on the one hand, they drink, on the other hand, used to entertain guests, but tea because of fear of light, fear of moisture, fear of high temperature, fear of odor and other characteristics become bad preservation, often take the time to find the tea has moldy deterioration, so the preservation of tea is particularly important, is to use self-sealing bags to preserve tea is a simple and effective The following is a simple and effective way to explain how to use self-sealing bags to preserve tea and the advantages of using self-sealing bags to preserve tea. The benefits of using self-sealing bags to preserve tea If the tea is exposed to direct light, it will destroy the amino acids and chlorophyll lost in the tea, and the substances inside the tea will be changed to produce an odor, which will reduce the quality of the tea, so the tea must be stored in a cool, dry and light-proof environment, and it is recommended to use opaque or dark-colored glass or ceramic bottles for storage, and then use food-grade self-sealing bags to divide the tea into small portions and store them in sealed containers. If you have desiccant, you can put desiccant into the container, so the effect will be better. The sealed tea should be placed in a cool, dry and ventilated environment, or in the refrigerator, and you must remember not to let the strong light shine directly on the container where the tea is stored. Because food-grade self-sealing bags are inexpensive, soft, high toughness, strong barrier, low temperature resistance, easy to use and other characteristics, so we recommend the use of food-grade self-sealing bags for tea storage, tea is particularly susceptible to a variety of flavors, so when storing tea to avoid and some stronger odor items together, the use of food-grade self-sealing bags can play a good role in sealing barrier to prevent When storing tea, be sure to use a brand new self-sealing bag for encapsulation, this is to prevent the self-sealing bag from being unclean and having residues to make the tea deteriorate. Through the above methods of storage tea can be stored for a long time, when you take only a small bag at a time, effectively avoiding the tea in the process of taking the influence of the external environment and deterioration, self-sealing bags can not only store tea, the same use of the advantages of self-sealing bags we can store a variety of food that needs to be preserved, such as a variety of nuts, food, herbs, etc. can use self-sealing bags for storage, self-sealing bags performance Excellent performance, low price, can be purchased anywhere, we can find in life to explore its more multi-purpose, so that the self-sealing bags to make a contribution to the convenient life.

How to buy air bubble bags?

Practically speaking, if you have bubble wrap on hand, cut it yourself with a knife, tape it and make a bag by hand to design a product of the right size. Why do this? Because manufacturers are generally designed on the large side, their own design size is not only more beautiful, but also can reduce costs. Note that leave some surplus, the factory production error of about 1cm, bubble bags made of bubble film, the quality of bubble film is a very important criterion. How to buy bubble bags? Some parameters of the bubble film are as follows: 1, material quality: generally divided into new and recycled materials. From the finished product, brand-new material bubble film volume color snow white, single piece of high transparency, no visible impurities, no pungent odor, feel comfortable; recycled material inside many kinds, also divided into good and bad, waste pipes and used cling film made out of a big gap, in short, the more the next color is black, the more opaque, the more impurities, the more pungent smell. Good recycled material single transparency is also very high, can be distinguished by looking at the film whether there are crystal points, recycled material melting unevenly, easy to produce crystal points. 2, bubble diameter: generally mainly 6mm, 10mm, 28mm these types, there are also 20mm (less common), there are heart-shaped bubble (special appearance, compression is not as round bubble). The most common is the 10mm bubble diameter, the pressure resistance of a wide range of applications. 6mm is characterized by a beautiful appearance, the bubble looks very neat, suitable for telephone and other products with external packaging, the main anti-wear, piggyback shock absorption. 20-28mm bubble diameter, are large bubbles, characterized by a higher bubble height, the general thickness of the film will also be made thicker, the best buffering and shock absorption effect. The following chart from left to right are 6mm, 10mm, 28mm bubble diameter. 3, thickness: this thickness is not the height of the bubble, but the thickness of the film (a few filaments of a few filaments). General newcomers are prone to ambiguity in this. Bubble film because you can not use a micrometer to directly measure the thickness, so the general use of how many grams per square meter (similar to A4 paper has 70g, 80g). The greater the gram weight, the stronger the pressure resistance, the harder the feel. In the picture below, 1, 2 pieces of bubble film of the same size, the same bubble height, is a light and a heavy. (1) 10mm bubble diameter common thickness from 35g/㎡ to 100g/㎡. Can also be made thicker, such as 200g / ㎡, but the cost is too high for the user, so rarely. By experience 65g-85g/㎡ thickness, are good choices, both good pressure resistance, and not high cost. (2) 6mm bubble diameter common thickness is also basically from 35g/㎡ to 100g/㎡. According to experience, this small bubble with 50g-70g/㎡ is more appropriate. (3) 20-28mm bubble diameter thickness, from 100g-200g/㎡ are used. The most commonly used is 200g/㎡. Because the bubble is large, the thickness if too thin, it is easy to burst. So the commonly used thickness is relatively small bubble in the bubble are thicker. 4, special processes: double-sided folder bubble, printing, color bubble film (1) double-sided folder bubble: also known as three-layer bubble film, is the two sides of the film in the middle bubble bubble film. This film of the same gram case, the compression resistance is not as good as ordinary bubble film. But compared to ordinary bubble film has certain insulation properties, and can be made into a tape seal. (2) printing: the structure is the same as the three-layer bubble film, one layer of flat film printed content, generally circular logo, the cost does not increase much, but a big step up in class. And can promote the brand and bring traffic. (3) colored bubble film: the production of adding masterbatches, you can produce the desired color, the market in addition to pink common some, other colors are relatively rare, the cost increases, the minimum order quantity increases, the product packaging is not significant.
