Detailed Description
The utility model will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in figure 1 and figure 2, the food bag for microwave oven cooking comprises
The bag body 2 is folded by a rolled film and is formed by heat sealing of the edges of the left side and the right side;
a zipper fastener 3 is arranged on the inner side of the upper bag opening of the bag body 2 to seal the bag cavity;
the bonding force between the two layers of the rolled films with the edges sealed at the left and right sides of the bag body 2 is C;
the left and/or right sealing edges of the bag body 2 are internally provided with valve channels 4, the adhesive force of two layers of rolled films between the valve channels 4 is C1, and C1 & lt C & gt.
Specifically, as an alternative embodiment in the present embodiment, as shown in fig. 1, the zipper fastener 3 is a double-layer zipper fastener. The inner side of the double-layer zipper fastener is opened more difficultly than the outer side of the double-layer zipper fastener, so that the bag opening can be prevented from being opened when the bag cavity is bulged.
Specifically, as an alternative implementation manner in this embodiment, as shown in fig. 1, two layers of rolled films at the mouth of the bag body 2 are connected by heat sealing.
Specifically, as an alternative embodiment in this embodiment, as shown in fig. 1, the bag body 2 is a self-standing bag. The bottom area of the self-standing bag is far larger than the top area, so that the stability in the using process can be supported.
Specifically, as an optional implementation manner in this embodiment, as shown in fig. 1, easy-to-tear openings are respectively provided on two sides of the mouth of the bag body 2. The bag opening after the heat sealing is convenient to open through the easy-tearing opening.
Specifically, as an alternative implementation manner in this embodiment, as shown in fig. 2, the roll film includes an inner layer 21, a middle layer 22 and an outer layer 23; the inner layer 21 is made of CPP, the middle layer 22 is made of PE, and the outer layer 23 is made of PET.
In this embodiment, the inner layer 21 is 2-6 filaments thick, the middle layer 22 is 3-6 filaments thick, and the outer layer 23 is 2-4 filaments thick.
The CPP, namely the casting polypropylene film, has good luster, higher tensile strength and tensile strength, and also has better heat resistance, cold resistance and oil resistance. The film is often used for packaging oily cooking sterilized food, can bear the cooking sterilization of 120 ℃ and 0.15Mpa pressure, not only maintains the shape and the flavor of the internal food, but also does not crack the film, and has little influence on the mechanical strength due to temperature change. Can resist 140 ℃ of high temperature in a short time, and ensures the safety of direct contact with food.
PE, polyethylene, has good folding resistance and little moisture resistance and permeability.
PET, polyethylene terephthalate, has excellent gas, water, oil and odor barrier properties. Therefore, in the using environment of the microwave oven, certain pressure of steam can be well ensured, the food is cured from inside to outside, and the taste is fresh, tender and juicy.
As a second embodiment of the roll film, the roll film includes an inner layer 21, a middle layer 22 and an outer layer 23;
the inner layer 21 is made of CPP, the middle layer 22 is made of PET, and the outer layer 23 is made of OPP.
As a third embodiment of the roll film, the roll film includes an inner layer 21 and an outer layer 23;
the inner layer 21 is made of CPP, and the outer layer 23 is made of PET.
As shown in FIG. 3, a plastic bag sealer 5 comprises an upper heater block 51 and a lower heater block 52 which can move up and down relatively, a notch 511 is formed in the upper heater block 51, when a laminated film is heat sealed by using such a heat gun, a valve passage 4 can be formed at the notch 511 due to a small clamping force when the two layers of the laminated film are held by the notch 511, and an edge heat seal is formed at the remaining position. Specifically, the edge heat seal bond C can withstand 20 kg of tension, and the valve port 4 bond C1 can withstand 2-3 kg of tension.
When in use, a consumer tears the easy-tearing opening, pulls open the double-layer zipper fastener, puts in the pickled raw food, pinches the zipper fastener 3 again, and puts in a microwave oven for heating and cooking. The food is heated to generate steam, the volume of the steam is increased to expand the bag body 2, and the elastic deformation generates certain pressure on the steam, so that the food is steamed and cooked and has tender mouthfeel; meanwhile, when the pressure reaches a certain degree, the pressure air valve with weaker sealing strength is automatically pushed open, steam is discharged, the dynamic balance of the internal and external pressure is achieved, and the bag body 2 is prevented from bursting; after the culinary art is finished, the external environment cooling, the sack is retracted gradually and is resumeed to normal condition, can not scalded by steam when opening the zip fastener, and the edge heat-seal mainly plays the mechanics support to the bag body 2.
In light of the foregoing description of the preferred embodiments of the present invention, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
