Description
Technical field
The utility model belongs to the soft package technology field, is specifically related to a kind of thermophilic digestion self-support bag.
Background technology
Thermophilic digestion self-support bag is meant the composite soft packaging bag that can stand high temperature (generally at 120 ~ 135 ℃) sterilization heating, because it has the effect of well standing voluntarily, Xin Ying packaged form relatively, low packing cost, promoting product specification, strengthening the shelf visual effect, carrying all many-sides such as light, easy-to-use, fresh-keeping and sealability and take advantage, begun to replace traditional can with high costs, be widely used in finished food of splendid attire such as meat, fish, bean product etc.Usually the bag of supporting oneself is made up of bag body and the bag ends two part; films such as the main polyester of its structure, aluminium foil, nylon, polypropylene are composited; the client can increase the oxygen barrier protective cover according to the needs of the different product of packing, and reduces oxygen permeability, prolongs the shelf life phase of product.
Because films such as polyester, nylon, polypropylene are high polymers, its complex film is difficult to tear, and in order to realize easy unlatching, the packaging bag both sides have tearing port usually, and then realizes easily tearing function.Although by the mode of tearing port, ratio was easier to Kaifeng when high-temperature retort bag was torn, and tore great efforts, crack propagation has no rule, breach lacks rectilinearity, causes the leakage of content easily, and therefore the used packaging film of above-mentioned packaging bag is not desirable easy Tear Film.In addition, also some uses laser rays to handle the technology of easily tearing, and laser rays carries out straight line with the polyethylene terephthalate of uppermost layer and easily tears processing, perhaps the cast polypropylene film of inside face or cast polypropylene film and nylon is carried out straight line and easily tears processing.But laser easily tears the integraty that treatment technology has destroyed film largely, cause packaging bag that this film makes in the thermophilic digestion sterilization process, barrier occurs in the laser treatment position and obviously reduce, even quick-fried bag, can't satisfy the shelf life of products demand, yield rate is low etc.
The utility model content
Technical problem to be solved in the utility model provides a kind of thermophilic digestion self-support bag with straight line easy-to-rupture energy, this self-support bag not only has the good effect of standing, and can effectively solve existing thermophilic digestion packaging bag and tear great efforts, crack propagation has no rule, and breach lacks linear problem.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of thermophilic digestion self-support bag with straight line easy-to-rupture energy, comprise bag body and be connected bag bag end of body bottom, the used packaging film of described bag body is three layers or four-level membrane, outer is the biaxial tension pet film, interlayer is that aluminum foil film and/or vertical straight line easily tear nylon film, internal layer is that vertical straight line easily tears polypropylene film, and above-mentioned film is combined with each other successively by adhesive for polyurethane;
Used packaging film is three layers or four-level membrane at the described bag end, skin is pet film or nylon film, interlayer is nylon and/or aluminum foil film, and internal layer is a cast polypropylene film, and above-mentioned film is combined with each other successively by adhesive for polyurethane;
The number of plies of the used packaging film in the described bag end is more than or equal to the number of plies of the used packaging film of bag body.
Described skin also prints and has or not benzene polyurethane or acrylic acid modified resin ink lay.
The spread of described adhesive for polyurethane is 4.0-4.5g/m
2
Have tearing port on the described bag edge sealing that the bag body is horizontal of supporting oneself.
The utlity model has following beneficial effect:
1, the vertical straight line of the utility model self-support bag bag used packaging film innermost layer of stature material easily tears polypropylene film, and the vertical straight line of interlayer easily tears nylon film, and two kinds of straight line easily tore films have longitudinal tear.
2, the used packaging film printed layers of the utility model bag body biaxial tension pet film has the molecular orientation of both direction in length and breadth, can strengthen the easy-to-rupture energy of bag body.
3, on the utility model self-support bag bag bag body transversal heat seal limit the longitudinal tear mouth is arranged, the longitudinal tear transmissibility is little, about 3-5N, rectilinear propagation is linearly propagated or approached to tearing port expansion line, tear line is regular, and tearing port has vertical rectilinear propagation, therefore has the advantage of easily openable, because tearing port is vertical straight line, the bag content of therefore supporting oneself is difficult for leaking.
4, the number of plies of used packaging film makes this self-support bag have the good effect of standing more than or equal to the number of plies of the used packaging film of bag body at the bottom of the utility model bag.
5, nylon film and the cast polypropylene film that does not adopt vertical straight line easily to tear at the bottom of the utility model bag, only the bag body uses, so cost reduces greatly.
Description of drawings
Fig. 1 has the structural representation of the thermophilic digestion self-support bag of straight line easy-to-rupture energy for embodiment 1;
