Description

A kind of packaging bag of unburned dish

Technical field

The utility model relate to a kind of storage that is used for food with or the container of transportation, be specifically related to a kind of packaging bag of unburned dish.

Background technology

Investigation from China Food Industry Association shows that along with the raising of resident living level, food consumption idea and mode quietly change, and a lot of families attempt to free from the kitchen, reduce fume pollution, alleviate housework.Unburned dish is just convenient with it, the characteristics of health, adapted to people's daily need, be subjected to people's welcome day by day, but unburned dish is when edible, usually need heating, particularly in the season of north cold, and present unburned dish adopts the packing of packed form all is to pack with common sealing bag, the normal packet pack of this unburned dish is because all unified envelope pressure of sealing part, packaging bag edge sealing place is stressed evenly, when micro-wave oven heats, because the moisture in the food gasifies fast, thereby make and produce barometric pressure in the packaging bag, very easily cause packaging bag in micro-wave oven, to be exploded, and might cause food to be splashed in the whole micro-wave oven, for fear of the generation of above-mentioned phenomenon, the customer needs food is taken out heating usually in packaging bag, but this kind type of heating can make the moisture loss in a large number in heat process in the food, makes that the food mouthfeel is dry and astringent, simultaneously, the local flavor of food also is lost in the air easily, and its operating process is loaded down with trivial details.

The utility model content

The utility model will solve the above-mentioned technological deficiency that present unburned green vegetable bun is contained in the appearance when heating in the micro-wave oven, and the packaging bag of convenient unburned dish can directly be useful in the micro-wave oven heats.

In order to solve the problems of the technologies described above, a kind of packaging bag of unburned dish is provided, include the bag that outer bag and inner bag constitute, the surrounding of outer bag and inner bag is by the edge sealing heat-sealing, and wherein, the inner bag internal layer has at least a periphery to be provided with recessed layer region.

Because the unburned dish packing box/bag of the technical program, the surrounding of outer bag and inner bag is by the edge sealing heat-sealing, and the inner bag internal layer has at least a periphery to be provided with recessed layer region.Unburned dish packing box/bag like this is provided with recessed layer region owing to periphery on certain edge sealing, in heat seal process, recessed layer region relatively the heat seal strength of other peripheral ordinary hot edge sealing under the normal temperature situation quite or low slightly, when the sealing bags that unburned dish is housed, be placed on when heating in the micro-wave oven, rising along with temperature and pressure in the bag, recessed layer region heat seal strength reduces at first, automatically at recessed layer region midway location exhausr port appears, discharge unnecessary gas in the packages sealed bag, prevent the vapours that unburned dish heating produces in the packaging bag, prevent the blast of packaging bag effectively, convenient unburned dish directly is useful in the micro-wave oven and heats.

Further, limit the recessed layer region described in the packaging bag of unburned dish and be arranged on the following internal layer of inner bag, the place also is coated with heat sealability coating at described recessed layer region.Adopt the packaging bag of such structure, because recessed layer region is arranged on the following internal layer of inner bag, conveniently heat sealability coating is coated with in the above, simultaneously, because heat sealability coating is in heat seal process, the anchoring strength of heat sealability coating is low relatively slightly, so more can guarantee when the sealing bags that unburned dish is housed, be placed on when heating in the micro-wave oven, rising along with temperature and pressure in the bag, the recessed layer region heat seal strength that scribbles heat sealability coating reduces at first, also can exhausr port occur at recessed layer region midway location automatically, discharge unnecessary gas in the packages sealed bag, prevent the vapours that unburned dish heating produces in the packaging bag, prevent the blast of packaging bag effectively, convenient unburned dish directly is useful in the micro-wave oven and heats.

Further, one of them the edge sealing inboard that is limited to the periphery of the recessed layer region of described correspondence also is provided with self-styled concave and convex strip.One of them edge sealing inboard of the periphery of the recessed layer region of described correspondence also is provided with self-styled concave and convex strip, this self-styled concave and convex strip structure makes inner bag form a kind of valve bag structure, because concave and convex strip is nothing like peripheral heat seal strength from seal structure from sealing strength, so when in micro-wave oven, heating, at first be that self-styled concave and convex strip opens earlier, recessed then layer region heat seal strength reduces at first, still exhausr port occurs at recessed layer region midway location automatically, discharges unnecessary gas in the packages sealed bag; But simultaneously, self-styled concave and convex strip like this, convenient interior when adorning unburned dish, earlier once self-styled, guaranteed the effect of encapsulation on the one hand, can guarantee also that on the other hand heat sealability coating can not contact with unburned dish, simultaneously, consider under the situation that unburned dish once do not eat up, can also adopt self-styled concave and convex strip to carry out repeatedly sealed storage.
