The technical implementation of the four-sided sealing bag involves the compression bag and the preparation process, especially the technical implementation and preparation process of the four-sided sealing bag, which belongs to the technical field of compression bag preparation, so let's learn about the production process of the next four-sided sealing bag together!

Compressed bags are also called PE zipper composite bags, which can effectively prevent fleas, fungi, moisture, oxidation, etc., and keep clothes clean. They can be divided into vacuum compression bags, suction cotton compression bags, manual vacuum compression bags, and manual Vacuum compression bags, etc.

The existing compression bag has the following defects:(1) The existing compression bag is sealed on three sides, and there is a zipper on one side. The three-sided sealing will affect the actual use area of the compression bag. (2) The three-sided sealed bag is easy to detonate when putting things in the compressed bag.

The technical implementation of the four-sided bag Technical implementation elements:

The main purpose of the technical implementation of the four-side sealing bag is to solve the shortcomings of the existing technology, and to provide a four-side sealing compression bag and a preparation process.

The antioxidant described is a phosphate ester, and the flame retardant is a phosphorus-containing flame retardant or a silicon-based flame retardant.

Preferably, the light stabilizer may be titanium oxide, phthalocyanine green or carbon black. Preferably, the use ratio of the wheat straw powder, the talc powder and the potassium feldspar powder is 1:2:2.

The manufacturing process of the technical implementation of the four-sided bag includes the following steps:

First, straw ash, potassium feldspar powder and talcum powder are crushed respectively, passed through 180-190 mesh sieve, and pushed for 6-8min at a temperature of 105-120 respectively.

Two: polyethylene, polyamide, polyester, straw ash, modified silicon powder, butadiene, ultra-high

The self-contained polyethylene fiber, polystyrene, magnesium stearate, antioxidant, flame retardant, light stabilizer, and the raw materials prepared in step 1 are mixed, and then the mixture is added to the reaction section to melt at a high temperature.

Three: input the melted raw materials into the extruder and extrude them into a single piece of compressed package. Use the single chip microcomputer of the compressed package to add two sides and seal the edges on the left and right sides of the package.

Four: Use the self-supporting knife mold and point sealing knife grinding to realize the bottom sealing of the bag. After the point sealing of the double-tooth zipper, a perfect arc shape appears, and the four-sided sealing bag is ready.

The beneficial technical effect of the technical implementation of the four-sided sealed bag: according to the four-sided sealed compressed bag and the preparation process of the present invention, both sides of the compressed bag can be sealed to increase the actual use area of the compressed bag and change the existing compressed bag Two-piece packaging method, thereby reducing explosion. The addition of polyethylene, polyamide and polyester in the preparation process of the compressed bag can effectively improve the strength of the compressed bag and avoid the thermal expansion and cold contraction of the compressed bag under different temperature conditions. Adding rice straw powder, potassium feldspar powder and supramolecular polyethylene fiber can improve the tensile strength and expansion performance of the compressed package and increase the life.
