Problems solved by technology
[0002] At present, aseptic prefilled agar medium plates are mainly used for microbial monitoring in clean environments. Specific medium products are used to monitor and cultivate planktonic bacteria, sedimentary bacteria, and surface bacteria in clean environments to determine the quality of clean environments. The cleanliness level meets the requirements. It is mainly used for the monitoring of microbial indicators in the clean environment of the pharmaceutical, food, cosmetics, and medical industries. After the culture medium is made, its later storage and transportation are very important. It is a paper-plastic bag structure. One side of the bag is made of an opaque air-permeable film, and the other side is a fully transparent PET / PE composite film, which makes it impossible to fully observe the internal state of the plate. Most of the opaque part of the air-permeable film is made of dialysis paper film material. , the membrane material is easy to absorb water, once condensation occurs in the culture medium, the dialysis paper material is susceptible to moisture, resulting in enlarged membrane aperture or paper damage, causing pollution and affecting the quality of the plate. In addition, the membrane material has low strength and a short service life. long
In addition, a sealing strip is provided around the middle layer or the outer layer of the medium plate, which is made by overlapping two film layers and then bonding the edges. This structure requires multiple bonding, and the manufacturing process is complicated, and the bonding is easy to cause Vacuum bag leaks, poor sealing effect, easy to cause internal pollution of the plate

The invention discloses a culture medium plate packaging bag which comprises an inner packaging bag, a middle packaging bag and an outer packaging bag. A packaging bag body comprises a closed inner packaging top bag, a middle layer multilayer coextrusion vacuumization packaging bag and an outer layer multi-layer coextrusion vacuumization packaging bag. The closed inner packaging top bag is of a double-layer bag body structure formed by pressing at least two top bag body sealing edges, a breathable film is of an opaque structure, a top bag body is of a transparent structure, the middle layer multilayer coextrusion vacuumization packaging bag is of a cylindrical integrally-formed structure, a cylindrical vacuum bag which is provided with an open top, free of seams in the middle position and used for containing finished products is defined by hot melting sealing strips and the bag body, and sterile standby paper plastic bags and standby blank pressure-sensitive tags are arranged in the vacuum bag; the outer layer multi-layer coextrusion vacuumization packaging bag is of a cylindrical integrally-formed structure, a cylindrical vacuum bag which is provided with an open top, free of seams in the middle position and used for containing finished products is defined by hot melting sealing strips and the bag body. By the adoption of the structure, sealing performance is guaranteed, external microorganisms can be well isolated, water and air can not permeate, and the culture medium plate packaging bag is resistant to puncture, tearing and abrasion.
