The utility model discloses a microwave oven heating automatic deflation packaging bag, which comprises a bag body, and the bag body is compounded by a heat sealing layer and a non-heat sealing layer, sealed edges are disposed on the bag body, a discontinuous cutting line is arranged in the heat sealing layer for cutting off the heat sealing layer discontinuously, an uncompounded opening region is arranged between the heat sealing layer and the non-heat sealing layer, the opening region is adjacent to the discontinuous cutting line and is disposed along the cutting line, and the opening region and the discontinuous cutting line at least penetrate through one sealed edge jointly. The utility model aims to provide the packaging bag for packaging convenience food such as various desserts, steamed breads, rice, seasoning soup, seasoning sauce and vegetables, the packaging bag can be heated in the microwave oven along with the food therein under the fully sealed condition, and the flavor of the food can be fully preserved in the food, so the use is safe and reliable, meanwhile, the means is more suitable for the high-speed automated packaging.
Description
Technical field
The utility model relates to a kind of novel microwave oven heating automatic deflation packing.
Background technology
Now, along with the quickening of people's rhythm of life, various instant food become more and more popular.Present instant food no longer is confined to instant noodles, instant bean vermicelli and so on, a large amount of appearance foods such as various dessert, steamed bun, rice, seasoning soup juice, seasoning dip, vegetables, their nutrition is balanced more, abundant, more approaches daily edible food.Some low temperature of these foods or refrigerated storage and sale, some then can normal temperature be handled, and only need being placed in the micro-wave oven once more before the customer is edible, heating is an edible.
Above-mentioned food, if pack with common sealing bag (or pallet), when micro-wave oven heats, because the moisture in the food gasifies fast, make and produce barometric pressure in the packaging bag, as shown in Figure 1, the sealing part of normal packet pack bag 1 all seals to press and forms edge sealing 2, each edge sealing 2 of packaging bag is stressed even, thereby very easily causes packaging bag to be exploded in micro-wave oven, and food might be splashed in the whole micro-wave oven.Take place for fear of above-mentioned phenomenon, the food manufacturer usually advises that the customer cuts off sack before heating, perhaps simply food is taken out heating in packaging bag, can make the moisture loss in a large number in heat process in the food so again, make that the food mouthfeel is dry and astringent, simultaneously, the local flavor of food also is lost in the middle of the air easily.
At present, this field some have occurred and has had the packaging pouch for microwave oven of automatic deflation function.A kind of is to make special heat-sealing shape to make thin spot on certain edge sealing of sack, when sack expands at the thin spot automatic deflation.Another kind is the front in packaging bag, and one and half through holes are arranged, and promptly outer rigid material has been opened a hole, and the internal layer heat-sealable material is still intact, and gas broke through this half through hole and emits automatically when sack expanded.Preceding a kind of mode can only be used the pre-formed bags pattern, is not suitable for high-speed automated packaging process.In a kind of sack production process in back, the sack of different size must be made a special version roller specially, and cost is higher.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the packaging bag that has the automatic deflation function when providing a kind of micro-wave oven to heat, this packaging bag can heated with the food that is placed in one under the leak free situation fully, flavours in food products can fully be retained in food inside, and is safe and reliable; Simultaneously, manner of packing helps high-speed automated packing.
In order to reach above-mentioned technical purpose, the utility model is realized by following technical scheme:
The packaging bag of a kind of micro-wave oven heating automatic deflation, comprise bag, described bag is composited by hot sealing layer and non-hot sealing layer, described bag is provided with edge sealing, be provided with a discountinuity cut-off lines that the hot sealing layer discountinuity is cut in the described hot sealing layer, be provided with not compound open area between described hot sealing layer and the non-hot sealing layer, contiguous cut-off lines in this open area and along the setting of moving towards of cut-off lines, an edge sealing is wherein passed in the combination of this open area and discountinuity cut-off lines at least.
Be bonded by adhesives between described hot sealing layer and the non-heat-sealing, described open area is an adhesive free area.
Described discountinuity cut-off lines is by physical method hot sealing layer to be cut, and the incision form is that discountinuity cuts, and promptly one section is cut, and one section is not cut, and its line style can be the straight line or the curve of multiple discountinuity incision such as dotted line, long and short dash line.
Packaging bag of the present utility model can be middle envelope, two bottom surface edge sealing of envelope during the combination of described open area and discountinuity cut-off lines is passed.
Packaging bag of the present utility model also can be three banding bags, and two side edge sealing of three banding bags are passed in the combination of described open area and discountinuity cut-off lines.
Packaging bag of the present utility model can also be four banding bags, and two side edge sealing of this four bandings bag are passed in the combination of described open area and discountinuity cut-off lines.
Compared with prior art, effect intentionally of the present utility model is:
(1) applied in any combination of the utility model hot sealing layer cut-off lines and open area makes the interior gas of bag obtain the passage of a release to edge sealing, makes packaging bag automatic deflation function-stable.
(2) the utility model can be emitted proper amount of gas as required automatically in micro-wave oven heat process, and the loss of moisture and local flavor can be stayed moisture and local flavor in the bag better in the minimizing food.
(3) the utility model packaging bag both can provide pre-formed bags to use, and also can provide the volume film, produced on high-speed automated baling line, and production efficiency is higher.
