1. Concept introduction: Ziplock bag (also known as compact bag, free bag, sealed bag, bone bag, English: Ziplock bags, Reclosable Bag, Zipper Closure Bag, Resealable Bag), with polyethylene (LDPE) and high-voltage line type Polyethylene (LLDPE) is a kind of plastic bag that can be repeatedly sealed by blowing film molding and eagerly cutting machine-made bags.

2. Uses: Ziplock bags can be used for internal and external packaging of various small items. Ziplock bags produced with food-grade raw materials can store all kinds of small food, tea, seafood, etc., moisture-proof, waterproof, insect-proof, and avoid the scattering of goods; Ziplock bags can also be used for the packaging of clothing and other daily necessities, which are widely used. Self-sealing bags can be produced by adding anti-static masterbatch during the production of blown film to produce anti-static self-sealing bags, which are individually used in the electronics industry.

3. Production process: The production of self-sealing bags is directly blown film forming, the individual above the self-sealing mouth is 1.8CM, and the self-sealing mouth is relatively thick. The left and right sides of the ziplock bag are made into finished products by heat-cutting and sealing.

4. Printing method: The printing method of ziplock bags is absolutely simple, only 1-2 colors can be printed, and multiple colors cannot be printed. Individual ziplock bags only print text and LOGO analogy to a single color.

Ziplock bags can be used for the inner and outer packaging of various small items (ornaments, hardware, toys).

Packaging, widely used . Self-sealing bags can be produced by adding anti-static masterbatch during film blowing production, which is generally used in the electronics industry.

Types: Self-sealing bags refer to packaging bags that can be automatically sealed by pressing. Commonly there are clip-chain self-sealing bags, blown bone (concave-convex bone) self-sealing bags, etc.

Ziplock ziplock bag (also known as compact bag, there are sticker bags, sealed bags, ziplock bags, keel bags, English: Ziplock bags, Reclosable Bag, Zipper Closure Bag, Resealable Bag), with polyethylene (LDPE) and high-voltage wire Polyethylene (LLDPE) is a kind of plastic bag that can be resealed by blowing film molding and hot-cutting machine-made bags. Common materials are PE, EVA, PO, multi-layer composite zipper bags, etc.

Uses: Ziplock bags can be used for Food packaging plastic bags internal and external packaging of various small items (ornaments, hardware, toys). Ziplock bags produced with food-grade raw materials can store various small foods, tea, seafood, etc., moisture-proof, odor-proof, waterproof, insect-proof, and prevent things from being scattered; Zip-lock bags can also be used for clothing and other daily necessities. Packaging, widely used . Self-sealing bags can be produced by adding anti-static masterbatch during film blowing production, which is generally used in the electronics industry.

There are two kinds of production of zippered self-sealing bags. One is direct film blowing. Above the self-sealing mouth is generally 1.8CM, and it is thicker near the self-sealing mouth. The method of attaching the clip chain, the latter method is mainly used in the production of composite bags. The production of self-adhesive self-sealing bags is mainly made of a single film cross-cut, heat-sealed on both sides, the length of the front and back of the bag is different, one side is 3-5cm longer than the other side, and the part can be folded back. When using colloids such as sex glue, tear off the plastic cover on the colloid and fold it back to seal the bag.

The following are the common specifications and dimensions of the ziplock bag. The thickness is generally 0.03mm on one side, also known as 3 wire, 3s, and 0.03mm~0.2mm, etc., and different thicknesses can be produced according to different needs.
