Description

A kind of for vacuum-packed packaging bag
Technical field
The present invention relates to a kind of anti-puncture packaging bag for Vacuum packing processes.More particularly, the present invention relates to a kind of anti-puncture packaging bag for Vacuum packing processes, be applicable to the object packing sharp angles.
Background technology
Usually the food processed can be loaded in packaging, to facilitate transport and food and extend holding time.As everyone knows, if the oxygen content in food Package is minimum or do not have, the microbial decomposition activity of food can reduce dramatically.Vacuum packaging is widely used in food Package, to reduce oxygen content.In a Vacuum packing processes, air is sucking-off from packaging bag, and packaging bag forms vacuum packaging together with the food be loaded into.Sack is sealed subsequently, and packaging bag inside forms the environment that is close to vacuum.The food variety being applicable to vacuum packaging storage comprises the food object that some are perishable, humidity is relatively low.Vacuum-packed packaging bag, due to the high suction in Vacuum packing processes, can be wrapped in the object in bag tightly, and after packaging bag sealing, packaging bag and package object can compress by bar pressure further.But, also there are some problems in vacuum packaging.When encountering this kind of package object containing sharp angles of such as paddy, wheat, lobster, shell seafood etc., packaging bag occurs damaged sometimes and pierces through.These objects containing sharp angles may be pricked and wear packaging bag in Vacuum packing processes.Sometimes, in transportation, these packagings are subjected to impact also can cause pierce through.In order to address this problem, the method that people adopt multilayer film to pack, but this method can not be entirely satisfactory, because these sharp-pointed objects sometimes still can pierce through the thin-film packaging layer of multilayer.In order to address these problems, we launch research, develop a kind of packaging bag being applied to Vacuum packing processes, have better anti-puncture and shock proof performance, can extend again the holding time of perishables simultaneously.
U.S. Patent number 6799680 proposes a kind of vacuum sealed package, and comprise the first and second impermeable interlayers, the surfaces externally and internally of each interlayer is identical, and is closed by adjacent three bandings, forms inner space.The inside face of the first interlayer and the second interlayer has the first and second channel networks respectively, and both are not connected mutually, when two interlayers link together, can form a powerful interconnecting channels network.Air can be discharged by the channel network be connected in packaging process.In order to be connected by the first and second channel networks, these passages need, with the long limit shape arrangement at a certain angle of interlayer, when such second interlayer overlaps on the first interlayer, can form interconnected channel network.The object of this invention is to provide a kind of heat sealable packaging bag, and for anoxybiotic or vacuum packaging, the interconnecting channels network formed in packaging allows gas can discharge from package interior.
Another US Patent 7220053 proposes for vacuum-packed flexible bags.This flexible bags comprises an inner bag and one and is wrapped in outer outer bag, and inner bag forms by printing dapple interlayer, and optimal case adopts at least four interlayers, when a dapple interlayer of print covers on another interlayer, forms interconnected pipeline.Similar to the above-mentioned US6799680 patent mentioned, the interlayer of inner bag of the present invention there is the annulus of several projection, when outer bag covers on inner bag, be connected with the passage of straw shape in outer bag, form interconnected passage.The present invention be intended to propose a kind of packing on vacuum packaging mechanical, it on ectonexine pack between passage make package interior air-energy high-efficiency pump out with vacuum pump.
The common ground of above-mentioned two technology is by interconnected channels designs, promotes the oxygen sucking-off in Vacuum packing processes, but does not improve the anti-of packaging bag and pierce through performance.In addition, above-mentionedly mention that two packaging bag productive costss invented are higher, because all interlayers all need to carve passage, to form interconnected channel network in follow-up covering process.And in the present invention, do not need interconnected passage.
Summary of the invention
The object of this invention is to provide a kind of packaging bag for Vacuum packing processes.Particularly have the packaging bag of higher puncture and impact resistance.
Another target of the present invention adds anaglyph on the outside face of packaging bag, makes it extra aesthetic.This can by being filled with a certain amount of air to reach in space airtight between interlayer, the place of these anaglyphs needs just to complete before Vacuum packing processes, like this when air in bag is drawn out of, formed in the process of vacuum, the air at embossment place still can maintain between interlayer.
The present invention can meet above-mentioned target.Optimum implementation of the present invention comprises the first and second plane interlayers, and they seal along two relative outer ledges, and the confined space in the middle of being formed carrys out packaging article; Third and fourth plane interlayer overlaps the relative outer ledge of on the first and second plane interlayers two, seals, becomes the outside face of an anti-puncture at container dimensions; A top forms enclosed interior space with a bottom opening together with the edge that interlayer is closed; Be characterized in, the third and fourth interlayer is connected on the first and second interlayers by some discrete points; In Vacuum packing processes, air in inner space and the air between first and the gap of the 3rd plane interlayer, second and the 4th between plane interlayer are sucked out, until packaging is finally sealed, sealing contents wraps up by the first and second interlayers, for these article provide the packaging of ground floor, pull the third and fourth interlayer to provide overpack for article simultaneously, pack by the difference of ground floor and overpack the puncture that effect strengthens packaging.
According to an embodiment, the first and second plane interlayers are two faces of a long and flat tubular body.Namely similarly, the third and fourth plane interlayer also can manufacture in an identical manner, and also two plane interlayers are two faces of a long and flat tubular body.
In packaging process according to an embodiment, once need the article stored to load packaging bag, the opening of packaging bag top and/or bottom is closed in Vacuum packing processes, and the operation may carrying out next step afterwards improves derivation packaging.
Another aspect of the present invention is that the first and second interlayers use Low Density Polyethylenes, linear low density polyethylene, medium density polyethylene material are made, and the third and fourth interlayer uses nylon etc., and other has bubble-tight thermoplastic material or other derivative film article to make.
Another aspect of the present invention causes anaglyph, to reach extra aesthetic at the 3rd or the 4th interlayer outside face of packaging bag.The method realizing anaglyph is: before Vacuum packing processes, when the 3rd and/or the 4th interlayer is sealed on the first and/or second interlayer, a certain amount of air is first closed between interlayer at the position of design anaglyph, like this, when in Vacuum packing processes, air is sucked, at anaglyph place, air still can be retained between interlayer.
