Problems solved by technology

[0005] The common point of the above two technologies is that through the interconnected channel design, the oxygen absorption performance during the vacuum packaging process is improved, but the anti-puncture performance of the packaging bag has not been improved.
In addition, the production cost of the packaging bag of the two inventions mentioned above is relatively high, because all the compartments need to be carved with channels, so that an interconnected channel network can be formed in the subsequent covering process

Embodiment Construction

[0016] It should not be difficult for a professional to realize that the present invention, in addition to its own characteristics, achieves the above-mentioned objects and advantages. The embodiment described here is not intended to limit the scope of the inventive solutions.

[0017] The present invention comprises a packaging bag (100) for use in a vacuum packaging process comprising first (110) and second planar compartments (120) sealed together along opposite outer edges on both sides to form a the inner space (190); the third (130) and the fourth plane interlayer (140) are overlapped on the opposite two outer edges of the first (110) and the second plane interlayer (120) and sealed to form a packaging bag (100 ) of the puncture-resistant outer surface; the top (170) and bottom openings (180) for communicating with the interior space (190) are formed by the unsealed portion of the partition edge; it is characterized in that the third (130) and the second The four compar...

Abstract

A packaging (100) for use in a vacuum packaging process comprises a first (110) and a second flat panel (120) sealed along two opposite lateral edges and forming an enclosure (190) for an article to be packaged; a third (130) and a fourth flat panel (140) superimposed on and sealed to two opposite lateral edges of the first (110) and second flat panels (120) forming a puncture resistant outer surface for the packaging (100); and a top (170) and a bottom opening (180) for accessing the enclosure (190) and formed by unsealed portions of the edges of the panels; characterized in that the third (130) and fourth panels (140) are joined to the first (110) and second panels (120) at discrete points (150); whereby during the vacuum packaging process, air can be withdrawn from the enclosure (190) and from recess between the first (110) and third flat panel (130) and second (120) and fourth flat panels (140) before the packaging finally sealed, whereby during the vacuum packaging process, the first (110) and second panels (120) wrap and enclose the object to provide a first layer of packing for the object and simultaneously pull along the third (130) and fourth panels (140) to provide a second layer of packing for the object, whereby the differential packing created by the first and second layers of packing creates a enhanced puncture resistant effects to the packaging.

Description

technical field [0001] The present invention relates to a puncture-resistant packaging bag used in a vacuum packaging process. More particularly, the present invention relates to a puncture-resistant packaging bag for use in a vacuum packaging process, suitable for packaging objects with sharp corners. Background technique [0002] Usually processed food will be packaged to facilitate transportation and extend food storage time. It is well known that the microbial decomposition activity of food can be greatly reduced if the food packaging contains minimal or no oxygen. Vacuum packaging is widely used in food packaging to reduce oxygen content. In a vacuum packaging process, air is sucked out of the bag, which forms a vacuum package with the food being filled. Then the mouth of the bag is sealed, and an almost vacuum environment is formed inside the bag. The types of food suitable for vacuum packaging storage include some perishable food objects with relatively low humidi...
