Abstract
The utility model relates to a microwave packaging bag which comprises a bag body. The microwave packaging bag is characterized in that a thermal contraction film is arranged between two combination films outside a sealing edge of the bag body, and the two combination films and the thermal contraction film are integrated through thermo-compression. The thermal contraction film is arranged on the sealing edge position of the packaging bag, the opening is sealed through the thermo-compression, and therefore loading strength is large and leakage is difficult. Due to the fact that no weak points which can influence edge sealing are arranged, the microwave packaging bag is safe and reliable to use. When the packaging bag is heated by microwave, the thermal contraction film outside the sealing edge of the bag body is heated and contracted, and holes are formed on the sealing edge position of the bag body, and therefore automatic discharge of air inside the bag through the holes is achieved. The microwave packaging bag has the advantages of being convenient to use and low in manufacture cost.
Description
Technical field
The utility model relates to a kind of packaging bag, particularly a kind of microwave package that is suitable for the weight packing.
Background technology
During with the food in the microwave heating sealing bags, the moisture vaporization in the food can cause packaging bag to expand, and produces explosion when reaching certain pressure, therefore, common food pack can not be directly used in microwave heating, usually needs in advance opening, prevent the packaging bag explosion, it is convenient not to use.At present, developed the packaging bag of energy automatic open when microwave heating, these sack major parts are to use the intensity that hot melt adhesive or hot knife design or other modes change the edge sealing point, make edge sealing heat seal strength thin spot, the gas that microwave heating is produced is easily gone out from this thin spot, reaches the purpose from opening.Because the intensity of packaging bag edge sealing thin spot is lower, heavier or when being subject to certain external impacts at the food weight that takes up, packaging bag is easily run-down at the thin spot place, cause packaging bag to be leaked, affect food security, reliability is relatively poor, so this class microwave packaging generally is only suitable for the lighter food of package weight.
Summary of the invention
The purpose of this utility model be to provide a kind of safe and reliable, load capacity large, the microwave package of the automatic open that is heated.
Technical solution of the present utility model is: a kind of microwave package, comprise bag, and it is characterized in that being provided with heat shrink films between two binding films at bag edge sealing place, be integral by hot binding between the three.
Described bag is provided with heat shrink films between two binding films at its edge sealing place, top or bottom edge sealing place or middle edge sealing place or two side sealing places, be integral by hot binding between the three.
Characteristics of the present utility model are: heat shrink films is arranged on the edge sealing place of packaging bag, and hot-press sealed, loading strength is large, is difficult for run-downly, does not establish the thin spot that affects edge sealing, and is safe and reliable.During microwave heating, the heat shrink films at bag edge sealing place is subjected to thermal contraction, produces hole at bag edge sealing place, realizes that gas passes through the hole automatic-discharging in the bag, and is easy to use, low cost of manufacture.
