Gas buffer packaging bag capable of preventing gas leakage

Abstract

The invention discloses a gas buffer packaging bag capable of preventing gas leakage, and relates to the technical field of gas buffer packaging bags. The gas buffer packaging bag is characterized inthat a gas guide cavity is arranged in the inner space of a packaging bag body at the upper sides of dividing strips, and the gas guide cavity is communicated with a gas inlet pipe; a plurality of square cavities are arranged in the packaging bag body through transverse parting strips and vertical parting strips in a matrix mode, gas guide hoses are fixedly arranged in the middles of the square cavities in the same column in a penetrating mode, the upper ends of the gas guide hoses are inserted into the gas guide cavity, and gas outlet nozzles are fixedly arranged on the outer side walls, extending into the square cavities, of the gas guide hoses; check valves are fixedly arranged at the inner end of the gas inlet pipe, the lower ends of the gas guide hoses and the interiors of the gas outlet nozzles; plastic bags are fixedly arranged on the front side walls of the interiors of the square cavities, the interiors of the plastic bags are filled with blocking glue, and a gas column is divided into a plurality of small squares, the contact area between a gas buffer bag and the outer surface of a product is increased, the product is better protected, and meanwhile, after the gas bufferbag is damaged and leaks gas, the inflation conditions of other gas column cavities are not affected.

Description

technical field [0001] The invention relates to the technical field of gas buffer packaging bags, in particular to a gas buffer packaging bag capable of preventing gas leakage. Background technique [0002] Gas cushion bag, also known as air column bag, is widely used in the packaging field of materials because of its good shockproof and drop-proof performance, especially for the packaging of some fragile products, which can play a very good role in protection; gas cushion bags are generally made of The gas cushion is folded and heat-sealed on both sides. The gas cushion is composed of multiple air column cavities, and all the air column cavities can be inflated at one time through the inflation port. This kind of gas cushion bag is safe and can protect the The packaged items are well protected for a long time; but the gas buffer bag in the prior art, after damage and air leakage, will appear difficult to inflate between other air column cavities, and at the same time, affec...

[0002] Gas cushion bag, also known as air column bag, is widely used in the packaging field of materials because of its good shockproof and drop-proof performance, especially for the packaging of some fragile products, which can play a very good role in protection; gas cushion bags are generally made of The gas cushion is folded and heat-sealed on both sides. The gas cushion is composed of multiple air column cavities, and all the air column cavities can be inflated at one time through the inflation port. This kind of gas cushion bag is safe and can protect the The packaged items are well protected for a long time; but the gas buffer bag in the prior art, after damage and air leakage, will appear difficult to inflate between other air column cavities, and at the same time, affect the impact of the gas buffer bag on the items. The protection needs to be improved urgently
