Abstract
The present invention belongs to the field of stuffing air bag producing technology, and is degradable hot cut and sealed stuffing air bag and its production process and hot cutting and sealing mold. The degradable hot cut and sealed stuffing air bag is produced with degradable LDPE plastic and through the process including the following steps: 1. co-extruding and blowing to produce double layer film of 15-25 microns each layer; 2. hot cutting and sealing to form air bag blank in a hot cutting and sealing mold; and 3. inflating and hot sealing the inflating nozzle to obtain the product. The degradable hot cut and sealed stuffing air bag has used in protecting the shape of case, bag, cap, shoes, etc, and has environment friendship, low production cost and high production efficiency.
Description
Technical field
The invention belongs to and fill the air bag production technical field, be specifically related to a kind of production method and particular manufacturing craft thereof of fervent packing filling degradable air bag.
Its inboard placement filler that needs carries out guarantor's type in the packing of product such as case and bag, shoes and hats, so that played buffering, beauty function in transportation, sales process.According to statistics, need the manufacturing enterprise of the similar filler of supporting use to reach tens0000 families, a year consumption reaches tens, and consumption is very big.The filler that present manufacturer generally uses has waste paper, foam, plastic hard plate etc., and not only there is the hygienic quality problem in these fillers, causes the pollution to environment after using, and also not satisfactory to the guarantor's type and the protection effect of products such as case and bag, shoes and hats.Also there is manufacturer to adopt the air bag of blow molding; because this air bag blow molding; the air bag wall thickness, the inflation oral pillar hard; the subject matter of its existence is that weight is big; use soft inadequately as filler; it is harder particularly to inflate oral pillar, is easy to cause to being filled contacting of product, influences the packaging protecting quality of product.Also increased the packing cost of product in addition, caused significant wastage, discarded environment and the garbage reclamation burden of having increased after filler uses.
Summary of the invention
At problems of the prior art; the object of the invention is to design the production method that a kind of fervent packing filling degradable air bag is provided and the technical scheme of particular manufacturing craft thereof; the air bag that production obtains has better guarantor's type, protection effect to Related product, and helps environmental protection.
Described fervent packing filling degradable air bag producing adopts conventional degradable LDPE doses of plastics, granulation, it is characterized in that comprising following process steps:
1) making every layer thickness through the double-layer coextrusion blown film is 1 5-25 micron bilayer film;
2) adopt the earnestly fervent press seal moulding of envelope mould, make the balloon membranes base of band charging connector;
3) the balloon membranes base is inflated and charging connector is sealed and promptly makes finished product.
Described fervent packing filling degradable air bag producing is characterized in that the every layer thickness of bilayer film is the 18-22 micron.
Described fervent packing filling degradable air bag producing is characterized in that the every layer thickness of bilayer film is the 19.5-20.5 micron.
Described fervent packing filling degradable air bag producing is characterized in that air bag inflation pressure is 0.3-0.8Pa.
Described fervent packing filling degradable air bag producing is characterized in that air bag inflation pressure is 0.4-0.6Pa.
Described fervent packing filling degradable air bag producing is characterized in that described fervent envelope mould comprises base plate and is arranged on the base plate and by the fixing heating wire of holder moulding.
The fervent envelope mould that described fervent packing filling degradable air bag producing is used is characterized in that comprising base plate and is arranged on the base plate and by the fixing heating wire of holder moulding.
The fervent envelope mould that described fervent packing filling degradable air bag producing is used is characterized in that the shape of heating wire is determined by the shape of air bag requirement.
The fervent envelope mould that described fervent packing filling degradable air bag producing is used is characterized in that base plate adopts high temperature resistant plate, and corresponding holder adopts and waters porcelain or high-temperature plastic material.
The fervent envelope mould that described fervent packing filling degradable air bag producing is used is characterized in that the height of holder in the electric heating wire type is lower than the outer height of type.
Aforementioned production method is simple for process; equipment needed thereby, mould structure are simple; the thin amount of the fervent packing filling degradable airbag wall that makes is light, and is effective as case and bag, shoes and hats inner chamber guarantor type, protection, can effectively keep product shape attractive in appearance when closed assembly, transportation and Over-The-Counter are sold.Harmless during use, the biodegradation easily of discarded back help environmental protection, and production cost is low, production efficiency is high, has further improved economic benefit.
Description of drawings
Fig. 1 earnestly seals the mould structure schematic diagram.
The specific embodiment
Adopt conventional degradable LDPE doses of plastics, granulation, making every layer thickness through the double-layer coextrusion blown film is bilayer film about 20 microns, degradable LDPE plastics compound method and prilling all adopt routine techniques, adopt the nontoxic recovery waste material of LDPE one-level, technology is equipped with biodegradation auxiliary agent, granulation routinely, can reach same technique effect.Bilayer film adopts fervent envelope mould as shown in Figure 1, and the balloon membranes base of being with charging connector is made in earnestly press seal moulding on small-sized press, and the pressing plate of installing on the press is the high-temperature resistant rubber plate, such as silicane rubber plate.This balloon membranes base is inflated and charging connector is sealed and promptly makes finished product.The every layer thickness of bilayer film adopts 18,19.5,20.5,22 microns to test and all obtain better effects respectively; Air bag inflation pressure adopts 0.3,0.4,0.6 respectively, 0.8Pa tests, and its guarantor's type effect and protection intensity all reach more satisfactory effect.
The fervent envelope mould that described fervent packing filling degradable air bag producing is used comprises base plate 1 and is arranged on the base plate 1 and by the fixing heating wire 3 of holder 2 moulding.Base plate 1 adopts high temperature resistant plate; arrange heating wire 3 in high temperature resistant base plate 1 bladder shape on request; adopt then and water ceramic material as holder 2; heating wire 3 is carried out moulding to be fixed; also can adopt the high-temperature plastic material to fix; water porcelain or high-temperature plastic fixedly the time; height in heating wire 3 types is lower than the outer height of type; simultaneously; the heating wire 3 that exposes to holder 2 surfaces is carried out grinding process, make the working surface of heating wire 3 become smooth arc surface, when the balloon membranes base earnestly seals; it is narrow to seal abutment joint; smooth; and seal butt joint intensity height, satisfy the inflation requirement of strength better, the balloon surface of making is level and smooth; soft; both to case and bag; the shoes and hats inner chamber has good guarantor's type; the protection effect has overcome similar existing product again quilt guarantor type product has been had the defective that hard thing contacts.Because this product consumption is very huge, adopt the technical program to greatly reduce production cost again, have vast market prospect and economic benefit.
Technical target of the product: 20 microns diaphragm hot strength 12mp; Yield strength is crossed 4.5mp; Air pressure is counted 0.5Pa; 90 ℃ of ageing-resistant intensity (no light source); 20 ℃ of degraded environment temperatures; Illumination is degraded after becoming polygon in 90 days.
