Problems solved by technology

Known plastic bags used for clothing packaging generally adopt PE film to be formed into bags after being burnt and compounded. The structure causes the pattern printed on the surface of the PE film to be rough, and because the strength of each plastic bag burnt edge is low, its reuse rate is low, which is not conducive to the recycling and reuse of plastic bags

Embodiment

[0013] Embodiment discloses a kind of composite zipper bag production method, comprises the following steps:

[0014] 1) Preparation of PPE film: mix polyethylene:polypropylene:opening agent with a weight ratio of 75:50:0.002, then blow mold PPE film through a blow molding machine, first fully stir the rice with an automatic mixer After about 30 minutes until it is evenly mixed, the stirred rice is sucked into the hopper by the automatic suction machine, and passes through the blow molding machine's material rod, filter screen, die head, automatic circulating cooling water ring, rubber roller, nip roller, electrostatic shock, The transition roller goes to the winding machine to be wound into a tube material. The blow molding machine is equipped with an automatic rotating die head. The temperature of the die head of the blow molding machine is controlled at 240-350°C, and the temperature between the main machine and the winder is adjusted according to the thickness of the PPE fi...

Abstract

The invention provides a production method of a compound zippered bag which has high intensity and is durable, comprising the following steps: polyethylene, polypropylene and opening agents are mixedaccording to the proportion that the polyethylene: polypropylene : opening agents is 75:50:0.02 by weight parts, and the mixture is blowing-formed into a PPE membrane by a blow molding machine, and the PPE membrane carries out static shock before being rolled; non-woven fabrics with 20-40g / m<2> of gram weight and a PE membrane are compounded to prepare the compound non-woven fabrics by a dry-typecompound machine; after the PPE membrane is broken, and then is compounded with the compounded non-woven fabrics, the surface by static shock backs on the compounded non-woven fabrics, the compoundednon-woven fabrics and the PPE membrane carry out roller ending treatment by a roller ending machine, a layer of printing ink is printed on the surface of the PPE membrane which carry out static shockby a color press, and the printing ink is obtained by uniformly mixing the printing ink, isopropyl alcohol and dimethylbenzene with the proportion of 5.8:2.2:1.5 by weight parts, and then the bag is formed after trimming treatment, and a zipper head is arranged at the opening position, so as to obtain the compound zippered bag.

Description

technical field [0001] The invention relates to a production method of a composite zipper bag, which belongs to the field of production of plastic bags and non-woven bags. Background technique [0002] Plastic bags are known and are widely used in the packaging of food and small items. Known plastic bags used for clothing packaging generally adopt PE film to be formed into bags after being burnt and compounded. The structure causes the pattern printed on the surface of the PE film to be rough, and because the strength of the burnt edge of each plastic bag is low, its reuse rate is low, which is not conducive to the recycling and reuse of plastic bags. Contents of the invention [0003] The purpose of the invention is to provide a method for producing a composite zipper bag with high strength and durability. [0004] The technical scheme that the present invention adopts is such: a kind of composite zipper bag production method comprises the following steps: [0005] 1),...
