Description
Technical field
The utility model relates to packaging bag, is specifically related to a kind of high temperature resistant butt-ended bag with venting position.
Background technology
High temperature resistant bag is also known as foods packed in carton containers, and referring to can packaged food can stand the laminated film bag of 110 DEG C ~ 125 DEG C of pasteurization process.At present, this type of packaging bag is widely used in the packaging of all kinds of ready-to-eat food.
The coating materials of bag film is the key factor of temperature capability, and the bag film that softening point is low, mechanical strength is weak easily pollutes built-in thing after the heating; In addition, because high temperature resistant bag is generally in heat process, the moisture of built-in thing expands under thermodynamic activity, when exhaust freely may not make a bag film burst; Seal not good, built-in thing may be caused to leak.
In addition, heat because high temperature resistant bag is also often placed in micro-wave oven, because the Fast Heating of micro-wave oven produces calorific effect, Fast Heating makes gas rapid expanding, more easily make bag break, in addition, microwave heating more easily destroys bag, bag is softened makes plastics penetrate in built-in thing, causes built-in thing to be polluted; And the mode that high temperature resistant bag horizontal is placed, when bag breaks, probably overflow because bag breaks in bag, while waste, also cause unnecessary cleaning puzzlement.
Utility model content
The purpose of this utility model is to provide a kind of high temperature resistant butt-ended bag with venting position, and its bag of film properties is excellent, resistance to heating, the venting position that it has can prevent bag in heat process from breaking, and by upright mode, when avoiding horizontal, bag breaks, and makes content overflow from bag.
For achieving the above object, the utility model adopts following technological means to be implemented:
With the high temperature resistant butt-ended bag at venting position, bag has several venting positions, bag by the left bag film of symmetry, right bag film, and the end bag film heat seal forms width range is continuously the heat seal seal area of 5 ~ 30mm; Venting position is positioned at bag top margin angle, in the heat seal seal area at venting position, there is some non-heat seal discharging air pipes in straight tube-like be arranged in parallel, heat seal seal area is led in non-heat seal discharging air pipe one end, the other end leads to a bag internal cavity, and the angular range of non-heat seal discharging air pipe and bag top margin is 20 ° ~ 60 °.
Further, the number of described non-heat seal discharging air pipe is 3.
Further, the width of the described non-heat seal discharging air pipe in straight tube-like is 1-3mm.
Further, the width spaces between described non-heat seal discharging air pipe is 0.5-1mm.
Preferably, described left bag film, right bag film, and end bag film is composite structure, ecto-entad is followed successively by pet layer, Ny layer, SPE layer, has bonding coat between each layer.
Usefulness of the present utility model is, the non-heat seal seal area at described venting position, to be arranged in parallel and in straight tube-like, it is 20 ° ~ 60 ° with top margin angle, when hot water heating, because hot water heating temperature traverse is comparatively slow, the steam that in bag, content produces after the heating makes bag expand lentamente, heat seal seal area makes bag be sealing state, and the toughness of bag can prevent content from overflowing;
When microwave oven heating food, because micro-wave oven adopts shortwave heating content, the change of content calorific effect short time greatly, undergoes rapid expansion produces a large amount of steam, Self stand bag+venting position is adopted to cut off venting position, allow and be arranged in parallel and expose in the non-heat seal seal area in straight tube-like, due to bag heat seal sealing, and with certain elasticity, the straight tube-like that non-heat seal seal area is set in parallel, the tubular area high speed ejection that steam only can be formed from non-sealing loci, the width of preferred non-heat seal seal area is 1 ~ 3mm, when opening can be prevented excessive, content is sprayed from bag, simultaneously, non-heat seal seal area forms different angles from top margin, be applicable to the use of difformity bag.
The bag film of this butt-ended bag can also select this bag film film, and ecto-entad is followed successively by pet layer, Ny layer, SPE layer, and between each layer, after bonding, heat seal is made.This bag of film innermost layer is SPE layer, can come excellent ductile strength and shock resistance for bag film strips, and good resistance to elevated temperatures; And its softening point is high, can prevent bag film from softening, toxin incorporates food, makes food content receive pollution; The two-layer of outermost has higher plasticity and suitable rigidity, and this three-decker can support that bag is upright and keep high temperature resistant, shock proof effect.

Detailed description of the invention
In order to the object of the utility model, feature, content can be understood further, below in conjunction with specific embodiment and accompanying drawing, the utility model is further described:
Embodiment 1
A kind of high temperature resistant butt-ended bag with venting position, bag has venting position 21, and bag is longer than the left bag film 11 of height, the right bag film with left bag film 11 symmetry by long edge lengths, and end bag film 12 heat seal continuously, heat seal width is 15mm, forms heat seal seal area 13; Venting position 21 is positioned at bag top margin angle, in the heat seal seal area 13 at venting position 21, has 3 and be arranged in parallel, the non-heat seal discharging air pipe 22 of width to be 1.5mm be straight tube-like, and the width spaces between non-heat seal discharging air pipe 22 is 0.5mm.Heat seal seal area 13 is led in non-heat seal discharging air pipe 22 one end, and the other end leads to a bag internal cavity, and non-heat seal discharging air pipe 22 is 22 ° with the angle of bag top margin, is applicable to bag height low, the butt-ended bag that width is larger.
When hot water heating, because hot water heating temperature traverse is comparatively slow, the steam that in bag, content produces after the heating makes bag expand lentamente, and heat seal seal area makes bag be sealing state, and the toughness of bag can prevent content from overflowing;
When microwave oven heating food, because micro-wave oven adopts shortwave heating content, the change of content calorific effect short time greatly, undergoes rapid expansion produces a large amount of steam, adopts Self stand bag+venting position to cut off venting position, allows be arranged in parallel and be that non-heat seal seal area in straight tube-like is exposed, due to bag heat seal sealing, and with certain elasticity, the straight tube-like that non-heat seal seal area is set in parallel, makes the tubular area high speed ejection that steam only can be formed from non-heat seal discharging air pipe 22.
Preferably, described left bag film 11, right bag film, end bag film 12 are composite structure, and the bag film of this butt-ended bag can also select this bag film film, and ecto-entad is followed successively by pet layer, Ny layer, SPE layer, and between each layer, after bonding, heat seal is made.This bag of film innermost layer is SPE layer, can come excellent ductile strength and shock resistance for bag film strips, and good resistance to elevated temperatures.
