Abstract
The present invention adopts the conventional blow moulding process, under the condition of a certain temp. and pneumatic pressure range uses several kinds of materials and makes them into tubular blank film through the process of co-extrusion, and makes the obtained tubular blank film undergo the process of single-side sealing treatment so as to obtain the invented vacuum packaging bag with the strong functions of isolation, isolating oxygen, resisting moisture, resisting high temp., resisting cooking and keeping freshness. It can save raw material, and can reduce cost.
Description
The invention belongs to packaging bag, particularly a kind of by the multilayer method for making of the single side sealed vacuum cooking packaging bag that forms of agent film altogether.
The present invention does not all adopt the vacuum packaging bag splendid attire for assurance food does not lose fresh, delicious, easy preservation in certain time limit in the past.Vacuum packaging bag in the past then adopts bilayer film monolithic calendering Compound Machining slabbing film, roll over again through after three heat seal edge sealing cut, cutting edge processes, and causes the production complex process therefrom, waste material, the barrier and the Keeping life of dress food in reducing.In addition, as quote the tubular base film that the plastics packed blow molding process of present making tubular makes, owing to adopt the thin and insufficient strength of bilayer film, thus can not boiling and monolateral heat seal, still can not satisfy the demand in user and market.
Purpose of the present invention aims to provide a kind of saving in material, cost-cutting, raising product barrier employing blowing manufacture craft, by multiple material time processing moulding tubular base film, is encapsulated as vacuum cooking and packaging bag through monolateral heat seal.
The objective of the invention is to realize with following scheme:
A kind of method for making of single side sealed vacuum cooking packaging bag is characterized in that, its adopts blowing manufacture craft commonly used, is 220-280 ℃ in temperature, by the multiple material tubular base film that is co-extruded, makes vacuum cooking and packaging bag after monolateral encapsulation.
Above-mentioned tubular base film can be processed by three kinds of raw material co-extrusions, and it is arranged in order from the inside to the outside and proportioning is (percentum %):
Polyethylene or polypropylene 45-55, adhesives 5-10, nylon resin 40-45.
Above-mentioned tubular base film can be processed by five kinds of raw material co-extrusions, and it is arranged in order from the inside to the outside and proportioning is (percentum %):
Polyethylene or polypropylene 35-45, adhesives 8-10, nylon resin 10-15, adhesives 8-10, nylon resin 28-30.
Processing makes color vacuum boiling packaging bag can add Masterbatch in above-mentioned various raw materials after.
Characteristics of the present invention are: owing to adopt multi-layer co-extruded film to form tubular base film, its intensity height, blowing is easy, the general layout of monolateral encapsulation has changed the complicated technology of three bandings dresses, and the barrier of product, fresh-keeping property, shelf-life and high temperature resistant anti-boiling have been improved, therefore can be widely used in fresh and dried fruit, the packing of pickles, meat product, fresh milk and liquid beverage and replace old-fashioned packaging product.
Below in conjunction with embodiment in detail the present invention is described in detail:
Embodiment one: with the vacuum blowing packaging bag that is composited of three-layer co-extruded film is example:
The three-layer thin-film raw material is arranged in order from the inside to the outside and is polypropylene 50%, adhesives 10%, homopolymerization nylon resin 40% respectively is divided in corresponding three blowing complex extruders commonly used, be heated to 220 ℃, 200 ℃, 240 ℃ respectively and can be combined in compound in the lump extruding in the same runner after becoming melt, its thickness is followed successively by 40,8,30 microns, make tubular base film through gas blowing, cooling and shaping, again vacuum cooking and packaging bag is made in the monolateral heat seal encapsulation in base.
Embodiment two: forming vacuum cooking and packaging bag with the five-layer co-squeezing film is example:
Five layer film raw materials are arranged in order from the inside to the outside and are polyethylene 42%, adhesives 8%, homopolymerization nylon resin 12%, adhesives 8% again, homopolymerization nylon resin 30% respectively is divided in five blowing complex extruders, be heated to 220 ℃, 200 ℃, 240 ℃, 200 ℃, 220 ℃ respectively and can be combined in coextrusion in the lump in the same runner after becoming melt, its thickness is followed successively by 30,5,10,5,25 microns, through gas blowing, typing makes tubular base film, again vacuum cooking and packaging bag is made in the monolateral heat seal encapsulation in base.
If need to make color vacuum boiling packaging bag, then, adopt above-mentioned manufacture craft with adding suitable Masterbatch in each raw material, can make color vacuum boiling packaging bag.
