Description
Technical field
The present invention relates to food pack to seal field, and in particular to one kind can deflation type sealing microwave bag and its sealing side
Method.
Background technology
In food packaging applications, food pack is often used.Food pack refers to directly contact with food, uses
In the membrane container for containing and protecting food.Food pack is one kind of package design, for the ease of fresh-keeping, storage in life
Food.
In order to further facilitate people's life, microwave bag starts to occur.Microwave bag full name microwave stove heat special packing bag,
Refer to can in the lump be put into the food pack that micro-wave oven carries out food heating with food in the state of not sealing off.
In the heating process of micro-wave oven, the temperature in packaging bag can gradually rise, therefore can produce air pressure.Air pressure is gradual
Rise, in the case of without exhaust, packaging bag, which is easily bursting at the collision, explodes.Therefore, existing microwave bag is sealing mostly
Discouraged road is reserved when being sealed at mouthful, is vented to be heated in micro-wave oven during expansion.But the presence in the road that loses heart can make microwave bag
Inside connected with ambient atmosphere, it is thus possible to can in microwave bag food produce pollution, influence food security.
The content of the invention
The purpose of the present invention is：There is provided one kind can deflation type sealing microwave bag and its mouth-sealing method, overcome drawbacks described above.
To achieve these goals, the present invention provides following technical solution：
One kind can deflation type sealing microwave bag, including bag body and heat-sealing impression, the heat-sealing impression be located at the sealing of bag body
At position；Be provided with leakage port on the heat-sealing impression, the heat-sealing impression includes seal area and buffering area, the seal area with
Buffering area close proximity, the seal area are located towards the side outside bag body, and the buffering area is located towards the internal portion of bag
Side, the leakage port relative to the line of demarcation of seal area and buffering area in symmetry shape set, the leakage port be fully located at by
Seal area and buffer set into heat-sealing impression region in.
Further, the width of the buffering area is more than the width of seal area.
It is a kind of can deflation type sealing microwave bag mouth-sealing method, comprise the following steps：
Step 1：Respectively selection with heat-sealing impression the corresponding first scald knife of seal area, the indentation width of buffering area and
Second scalds knife；
Step 2：By first scald knife and the second boiling hot knife, arrangement position simultaneously fix by clamping on machine；
Step 3：Machine drives first scald knife and second to scald knife at the same time to bag body progress heat-seal operation, and in heat-seal operation
During knife scalded to first scald knife and second carry out temperature control and pressure respectively and control, obtain by seal area and buffer set
Into heat-sealing impression；
Step 4：Leakage port is gone out using the intersection of seal area of the punching die on bag body and buffering area.
Further, in step 3, the temperature control of first scald knife is 155~170 DEG C, and pressure control is 20~30N/
cm2, the width of obtained seal area is specially 0.4~0.8cm；Second temperature control for scalding knife is 145~155 DEG C, pressure control
It is made as 12~19N/cm2, the width of obtained buffering area is specially 0.8~1.2cm.
Beneficial effects of the present invention are：One kind can deflation type sealing microwave bag and its mouth-sealing method, heat is being carried out to bag body
Feng Shi, is controlled with pressure by the way that two boiling hot knives are carried out with different temperature respectively, obtains seal area and buffering area, and in seal area
The intersection of buffering area is provided with leakage port；When microwave bag heats in micro-wave oven in the lump with food, it is heated in microwave bag
Start produce gas expansion, after the air pressure for reaching certain, buffering area will be softened so that the gas in microwave bag from lose heart
Mouth discharge, avoids the excessive bad phenomenon exploded of air pressure in microwave bag, while the discouraged road of existing microwave bag can be avoided to lead
The defects of being connected in the bag of cause with outside atmosphere and then being possible to produce food pollution, ensures food security.
