Clothing Plastic Bag Type
1. Self-adhesive bag
Self-adhesive bags are similar to flat bags, except that a sealing strip is added. Self-adhesive bags are mainly used for inventory packaging of clothing, packaging of gifts, packaging of small commodities, etc. Some self-adhesive bags have a punched card on the top, which is mainly used to hang on the shelf for sales and visits.
There are two printing methods for self-adhesive bags, one is inner printing and the other is outer printing. Different printing methods are used according to the use requirements. If you do not want the ink to fall off and adhere to the product, you will mostly use the surface printing process. If the printing surface is large or you want the surface to be smooth and bright, you will mostly use the inner printing method, because the self-adhesive bag The adhesive force of the adhesive tape on the printing surface is very poor, and it will not be affected only if it is printed inside.
Generally, there is a sticker on the mouth of the self-adhesive bag. When using it, tear off a small piece of plastic paper on it to seal the self-adhesive bag. It is usually disposable, so many e-commerce clothing brands give up. Use self-adhesive bags as packaging bags for garments.
2. Zipper bag
The widespread reason is the rapid development of e-commerce. However, ordinary PP self-adhesive bags are always not glued properly when customers return the goods, so the bags cannot be used again, and they are also prone to dust during transportation. According to data, the return rate of Taobao stores for clothing categories can even reach 40%, so plastic zipper bags are gradually being widely used by clothing brands.

After the product is placed, the frosted material is used as the background to better set off the product. Sophisticated and high-end.

3. Tote bag
Plastic handbags are usually divided into four types: bottom and side, bottom and no side, bottom and side, and bottom and side. The vast majority of customers choose the style with sides after considering the beauty and practicality. One reason is that the style with sides is more three-dimensional and more beautiful, and the bag can stand upright and will not fall down on the ground. At the same time, patterns, logos or QR codes can also be printed on the side, which increases the chances of being noticed by others.
The production process of plastic handbags is more complicated than other plastic bag styles. After printing, the two sides need to be folded out by an organ folding machine, and then some styles need to be manually bottomed, and the bottom is folded by a machine. Well sealed, the last thing is to use a machine to fix the two handles at the mouth of the bag.
Although it is a plastic bag, this style that is close to a paper bag requires 3 manual processes, so the cost is much more expensive than other styles. Therefore, many people adopt the one-piece style with a bottom and no sides in order to save costs.
4. Flat pocket
The materials used for flat bags are only PO and PE. Compared with other styles, the application range of flat bags is wider and can basically cover all walks of life.

Common ziplock bags are made of PE, EVA, etc., and there are also multi-layer composite bags, which are usually used for packaging electronic components of electronic products, and anti-static masterbatch is usually added to the material.
There are usually two production processes for ziplock bags. One is that the zipper is blown out together with the bag itself when the film is blown. Another process is to attach the zipper to the bag when making the bag, which is usually used in composite sealed bags.
The relatively high-end product words are made of EVA material. Ziplock bags of this material cannot be produced on bag making machines, but can only be manually pressed and formed by high-frequency machines and molds. Therefore, although the finished products of this type of ziplock bags are very beautiful, the production cost Relatively high, generally this kind of bag is used to pack high-end underwear.
