Description
Technical Field
The utility model relates to the field of medical sterilization packaging bags, in particular to a medical sterilization paper-plastic packaging bag.
Background
The traditional medical packaging bag is made of plastic film or aluminum foil composite film material, wherein three edges are sealed to form a cavity, and after the object to be packaged is put into the cavity, the fourth edge (namely a bag opening) is sealed by ironing, so that the medical packaging bag is convenient to store. However, although the packaging bag has good sealing performance, the packaging bag is not suitable for medical packaging with steam sterilization or ethylene oxide sterilization, because the packaging bag is inconvenient for the sterilization medium to enter and exit.
In order to be suitable for steam sterilization or ethylene oxide sterilization, a ventilation part must be added on a packaging bag, so that a sterilization medium can enter and exit from the ventilation part, and thus, medical paper-plastic bags (one surface of the packaging bag is medical dialyzing paper, and the other surface is a plastic composite film), full paper bags, top bags (the edge of one surface at the bottom of the full plastic bag is added with a packaging bag made of a ventilation material), middle-seam ventilation bags (the position of a joint sealed in the full plastic bag is added with a packaging bag made of a ventilation material) and the like appear in the market.
Referring to fig. 1 and 2, a conventional medical paper-plastic bag is provided, in which one side is a plastic composite film 3 ', the other side is medical dialysis paper 4', three edges are sealed and bonded to form a sealing connection part 5 ', the other edge is reserved as a bag opening 1', and the part opposite to the bag opening 1 'is a bag bottom 2'.
Although these packages can be steam sterilized or ethylene oxide sterilized, each package still has various disadvantages, such as: the middle-seam breathable bag and the top bag have small occupied area, so that the entering and exiting of sterilization media are influenced, particularly, the analysis after ethylene oxide sterilization (the residual is reduced as much as possible because the ethylene oxide is toxic and needs to be fully analyzed after the sterilization) needs a long time, and the use efficiency of products is greatly influenced; the whole paper bag has good air permeability, but has poor visibility, and the product in the package cannot be clearly seen; the medical paper-plastic bag is one of the most popular sterilization packages compared with other packages, but the medical paper-plastic bags on the market have the condition of insufficient ventilation effect, particularly the phenomenon of bag explosion caused by steam sterilization of larger articles, the phenomenon of incomplete analysis after ethylene oxide sterilization and the like.

The utility model aims to provide a medical sterilization paper-plastic packaging bag, so that the problems that the medical sterilization packaging bag in the prior art is not good enough in ventilation effect, can explode and is not completely resolved after ethylene oxide sterilization are solved.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a wrapping bag is moulded to medical sterilization paper is sealed along the three sides by first sheet and second sheet and scalds the bonding and form, and a minor face that does not seal and scald forms the sack, with the part that the sack is relative is at the bottom of the bag, first sheet is formed along bag body length direction concatenation by first plastic composite membrane and first medical dialysis paper, and the second sheet is formed along bag body length direction concatenation by second plastic composite membrane and the medical dialysis paper of second to first plastic composite membrane is relative on bag body thickness direction with the medical dialysis paper of second, and first medical dialysis paper is relative on bag body thickness direction with second plastic composite membrane.
Preferably, the first plastic composite film and the first medical dialysis paper are bonded by sealing and ironing, and the second plastic composite film and the second medical dialysis paper are bonded by sealing and ironing.
Particularly preferably, the first medical dialysis paper has a length shorter than that of the first plastic composite film, and the second medical dialysis paper has a length shorter than that of the second plastic composite film.
Preferably, in the middle of the medical sterilized paper-plastic packaging bag, a part of the first plastic composite film is opposite to a part of the second plastic composite film.
Preferably, the first plastic composite film and the second plastic composite film are PET/CPP composite films with the thickness of 0.045-0.055 mm. It should be understood that the PET/CPP composite film is a thin film formed by compounding a PET film and a CPP film in a composite assembly. The PET/CPP composite film has good air tightness, good printing and coloring, has good barrier effect on gas or moisture, and is generally applied to the fields of food packaging, medical sterilization and the like.
Preferably, the gram weight of the first medical dialyzing paper and the gram weight of the second medical dialyzing paper are 60-70 g/m2。
In order to realize that the sterilization medium can be sufficiently convected in the medical paper-plastic bag and the original performance of the paper-plastic bag is not influenced, the structure of the traditional medical sterilization paper-plastic bag is innovatively designed. The medical dialyzing paper and the composite film can be sealed and ironed for adhesion, the composite film and the composite film can be sealed and ironed for adhesion, the medical dialyzing paper and the medical dialyzing paper can not be directly sealed and ironed for adhesion, and the two surfaces of the medical paper-plastic bag are respectively ironed and connected by the medical breathable paper and the plastic composite film, so that the two surfaces are both provided with breathable materials, the visibility is realized, and the production process can be met.
Compared with the prior art, the medical sterilization paper plastic packaging bag provided by the utility model has the following advantages:
1) during sterilization, the sterilization medium can be more conveniently fed and discharged, so that the sterilization is more thorough;
2) when the pressure steam is used for sterilization, as the two sides are provided with the ventilating parts, the circulation effect is better, condensed water is not easy to generate, and the risk of wet packaging is reduced;
3) during ethylene oxide sterilization, good ventilation circulation is realized, so that the sterilization is more thorough, and the residual ethylene oxide after sterilization can be analyzed more quickly and fully;
4) the front and the back can be used for easily seeing the content clearly;
5) compared with the traditional medical paper-plastic bag, the strength is better.
In conclusion, the medical sterilized paper-plastic packaging bag provided by the utility model has the advantages that the sterilization effect is more thorough, the wet packaging risk is reduced, the ethylene oxide is fully analyzed, the visibility is higher, and the strength is better.
