By using above-mentioned technical proposal, the thickness of weakened region is less than the thickness of non-weakened region, consequently facilitating gas will subtract Weak area opens, consequently facilitating the gas in packaging bag is discharged when heated, so that the case where collapsing bag is reduced, consequently facilitating Food in packaging bag is heated, consequently facilitating being eaten to the food in packaging bag.

The utility model is further arranged to: several stripeds are offered on the weakened region.

By using above-mentioned technical proposal, the striped in weakened region can further decrease the intensity of weakened region, thus just It is washed open in by the weakened region on outer membrane, consequently facilitating packaging bag is discharged in the gas in packaging bag, to reduce packaging bag Collapse bag.

The utility model is further arranged to: the weakened region setting is fluted, the through-hole on the groove and boot section It is corresponding.

By using above-mentioned technical proposal, groove is corresponding with the through-hole of boot section, thus in swollen bag, convenient for making packaging bag Interior gas is washed open the weakened region on outer membrane by through-hole, so that the gas in packaging bag is discharged out of packaging bag, from And convenient for being heated to the food in packaging bag.

The utility model is further arranged to: the through-hole on the boot section is interconnected.

By using above-mentioned technical proposal, the through-hole on boot section is interconnected, consequently facilitating reinforcing the company between through-hole It connects, thus when being heated to packaging bag, convenient for washing the weakened region on outer membrane open, consequently facilitating by the gas in packaging bag Body discharge.

The utility model is further arranged to: being provided with anti oxidation layer on the inner layer film.

The utility model is further arranged to: the anti oxidation layer is ethylene-vinyl alcohol copolymer.

By using above-mentioned technical proposal, ethylene-vinyl alcohol copolymer has good barrier action, consequently facilitating to bag Intracorporal food is saved, and the time of food spoilage is extended.

In conclusion the advantageous effects of the utility model are as follows:

1. the food of carrying liqs is filled in packaging bag, when being heated with micro-wave oven to the food in packaging bag, packaging Water in bag is heated and can gasify, to make packaging bag swollen bag；To which gas is opened outer membrane by the through-hole on inner layer film, from And gas is discharged from boot section, the gas in packaging bag is discharged to complete to orient, so that the case where collapsing bag is reduced, Consequently facilitating being heated to the food in packaging bag, consequently facilitating being eaten to the food in packaging bag；

2. the thickness of weakened region is less than the thickness of non-weakened region, consequently facilitating gas opens weakened region, consequently facilitating The gas in packaging bag is discharged when heating, to reduce the case where collapsing bag, consequently facilitating to the food in packaging bag into Row heating, consequently facilitating being eaten to the food in packaging bag；

3. the striped in weakened region can further decrease the intensity of weakened region, consequently facilitating by the weakened region on outer membrane It washes open, consequently facilitating packaging bag is discharged in the gas in packaging bag, so that reduces packaging bag collapses bag.

Detailed description of the invention

Fig. 2 is the schematic diagram for embodying inner layer film and outer membrane.

In figure, 1, bag body；11, inner layer film；111, boot section；112, through-hole；12, outer membrane；121, weakened region；122, recessed Slot；2, edge sealing area；3, accommodating chamber.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

It referring to Figures 1 and 2, is a kind of microwave stove heating packaging bag disclosed by the utility model, including bag body 1, bag body 1 Edge be edge sealing area 2；The middle part of bag body 1 is accommodating chamber 3, the closing setting of accommodating chamber 3；The side wall of bag body 1 includes inner layer film 11 With outer membrane 12, inner layer film 11 and outer membrane 12 are bonded；Inner layer film 11 is provided with anti oxidation layer close to the side of accommodating chamber 3, resists Oxide layer is ethylene-vinyl alcohol copolymer.

Food is placed in the accommodating chamber 3 of bag body 1, the edge sealing area 2 at 1 edge of bag body seals food in accommodating chamber 3 up for safekeeping, To be sealed to food；Ethylene-vinyl alcohol copolymer on inner layer film 11 has good barrier action to reduce food The time that object is oxidized, consequently facilitating being saved to food.

Be provided with boot section 111 on inner layer film 11, offer multiple through-holes 112 on boot section 111, adjacent through-holes 112 it Between be interconnected；Outer membrane 12 is provided with weakened region 121, weakened region 121 at the position corresponding to the boot section 111 of inner layer film 11 Thickness be less than outer membrane 12 on non-weakened region 121 thickness；It is provided on weakened region 121 and the through-hole 112 on inner layer film 11 Corresponding groove 122；Several stripeds are provided in weakened region 121.

Through-hole 112 is set on inner layer film 11, consequently facilitating the gas in bag passes through inner layer film 11 out of through-hole 112, thus It is contacted with the weakened region 121 of outer membrane 12；The thickness of weakened region 121 is less than non-weakened region 121 on outer membrane 12 on outer membrane 12 Thickness, to reduce the intensity of weakened region 121, so that weakened region 121 is easy to be broken through during swollen bag, consequently facilitating Gas in bag body 1 is discharged in air, so that discharge is oriented to the gas in bag body 1, to reduce the gas in bag body 1 Body, to reduce the case where collapsing bag.

The implementation principle of the present embodiment are as follows: when the food to carrying liqs heats, packaging bag is placed on micro-wave oven In heated；During heating, the liquid gasification in packaging bag, to make packaging bag swollen bag；Gas in packaging bag is logical It is contacted after the through-hole 112 crossed on inner layer film 11 with the weakened region 121 on outer membrane 12, thus during swollen bag, it first will be outer Weakened region 121 on tunic 12 is burst, to make gas be discharged out of weakened region 121, to carry out to the gas in packaging bag Having directional exhaust, to reduce the gas in packaging bag, to reduce the pressure in packaging bag, so that the case where collapsing bag is reduced, from And convenient for being heated to the food in packaging bag, consequently facilitating being eaten to the food in packaging bag.

The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical Within novel protection scope.
