The production process of four-side sealing bags

The technical implementation method of four-side sealing bags involves compression bags and preparation processes, especially the technical implementation methods and preparation processes of four-side sealing bags, which belong to the field of compression package preparation technology. So let’s learn about the production process of four-side sealing bags!

Compression 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. Vacuum compression package, etc.

The existing compression package has the following defects: (1) The existing compression package is sealed on three sides, with a zipper left on one side. The three-sided sealing will affect the actual use area of the compression package. (2) Three-sided sealed bags can easily explode when putting things in them.

Technical implementation methods of four-side sealing bags Technical implementation elements:

The main purpose of the technical implementation of four-side sealing bags is to solve the shortcomings of the existing technology and provide four-side sealing compression bags and preparation processes.

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

Preferably, the light stabilizer may be titanium oxide, phthalocyanine green or carbon black. Preferably, the usage 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 four-side sealing bags includes the following steps:

1: Straw ash, potassium feldspar powder, and talc powder are crushed separately, passed through a 180 ~ 190 mesh sieve, and pushed at a temperature of 105 ~ 120 for 6 ~ 8 minutes.

2: Polyethylene, polyamide, polyester, straw ash, modified silica powder, butadiene, ultra-high

After mixing the self-measured polyethylene fiber, polystyrene, magnesium stearate, antioxidant, flame retardant, light stabilizer and the raw materials prepared in step 1, add high temperature to the reaction part to melt.

Three: Input the melted raw material into the extruder and extrude it into a single piece of compressed package. Use the compressed package single-chip machine to add two sides to the left and right sides of the package and seal the edges.

Four: Use the self-standing knife mold and point-sealing knife grinder to achieve the bottom sealing of the bag. After point-sealing the double-tooth zipper, a perfect arc shape will appear, and the four-side sealing bag is ready.

Beneficial technical effects of the technical implementation of the four-side sealing bag: According to the four-side sealing compression bag and the preparation process of the present invention, both sides of the compression bag can be sealed to increase the actual use area of the compression bag and change the performance of the existing compression bag. Two-piece packaging method to reduce explosion. Adding polyethylene, polyamide and polyester during the preparation process of compression bags can effectively improve the strength of the compression bag and avoid thermal expansion and cold contraction of the compression bag under different temperature conditions. Adding straw powder, potassium feldspar powder and supramolecular polyethylene fiber can improve the tensile strength and expansion performance of the compression package and extend its service life.

The manufacturing process of the technical implementation of four-side sealing bags includes the following steps:

1: Straw ash, potassium feldspar powder, and talc powder are crushed separately, passed through a 180 ~ 190 mesh sieve, and pushed at a temperature of 105 ~ 120 for 6 ~ 8 minutes.

2: Combine polyethylene, polyamide, polyester, straw ash, modified silica powder, butadiene, ultra-high molecular weight polyethylene fiber, polyphenylene sulfide, magnesium stearate, antioxidants, flame retardants and light stabilizers After mixing with the manufactured raw materials, the high-temperature melt is added to the reactor.

Three: Input the melted raw material into the extruder and extrude it into a single piece of compressed package. Use the compressed package single-chip machine to add two sides to the left and right sides of the package and seal the edges.
