Problems solved by technology

Traditional nylon vacuum packaging bags can only be vacuum-packed with high-cost van-type industrial vacuum packaging machines, but cannot be vacuum-packed with portable table-top or palm-type suction nozzle vacuum sealing machines. At the same time, it is also impossible to adopt direct closed microwave heating
And the microwave packaging bag that announcement number is 522123 " packaging bag and manufacturing method " invention provides also can't carry out the vacuum packaging of food with desktop type or palm type suction nozzle type vacuum suction sealing machine, makes its use limited, especially The use in the family is greatly restricted, and it is impossible to conveniently use the desktop vacuum sealing machine for general household use for food packaging

Embodiment Construction

[0032] Microwave heatable vacuum packaging bag provided by the present invention, such as Figure 1 to Figure 6 As shown, it at least includes a first film layer 51 , a second film layer 52 and an air guide layer 53 . The air guide layer 53 is interposed between the first film layer 51 and the second film layer 52 , and can also be directly combined with the first film layer 51 or the second film layer 52 . The first film layer 51 and the second film layer 52 are respectively provided with heat-resistant layers 511 , 522 and heat-sealing layers 512 , 521 . A plurality of essentially airtight microscopic gap structures 15 can also be set on the first film layer 51 or the second film layer 52, which has the following two manufacturing methods:

[0033] The first method, such as Figure 7As shown, a first film layer 51 without a microscopic gap structure 15 or an inner edge of a second film layer 52 is combined with an air-conducting layer 53 by thermal bonding and pressing, an...

Abstract

A vacuum packing bag able to be heated by microwave is composed of a bag body consisting of the first and the second film layers with refractory layer and heat-sealed layer, and a gas permeable layer between said two film layers. At least one of said two film layers has a layer of directionally extended film, and an air-tight automatic pressure regulating region in air permeable mode, in which there are multiple sealed microgap structures. Its making method is also disclosed.

Description

technical field [0001] The invention relates to a microwave-heatable vacuum-package bag and a manufacturing method thereof, which are used in vacuum-package of various foods and can regulate part of the over-high steam pressure during the microwave-heating process. Background technique [0002] Most of the traditional sealed food packaging materials are made of plastic film with low air permeability. During the heating process, especially the microwave heating process, the steam in the sealed space is often heated and pressurized rapidly, and the air permeability and strength of the packaging material itself are insufficient. The inability to support results in the inherently unavoidable bursting of food packaging materials. In order to avoid this phenomenon, general food packaging manufacturers suggest that before heating or cooking food in a microwave oven, the food packaging bag or box must be opened to allow timely adjustment of the high-temperature and high-pressure gas...
