Description
Technical Field
The utility model relates to the field of sterilization packaging of medical instruments, in particular to a medical sterilization breathable packaging bag.
Background
At present, most of the top breathable packaging bags on the market have structures as shown in fig. 1 and 2, wherein a first polyethylene film 1 and a second polyethylene film 2 are used as an upper sheet and a lower sheet, and are connected along three sides in a sealing and ironing manner to form a cavity, wherein a part of adhesive-coated Tyvek (Tyvek) 4 is used as a breathable part at the tail end of the first polyethylene film 1 at the bottom of the bag, the adhesive-coated Tyvek 4 comprises a Tyvek material 41 and an adhesive layer 42, a bottom sealing and ironing connecting part 6, a first side sealing and ironing connecting part 8 and a second side sealing and ironing connecting part 9 are formed after the adhesive-coated Tyvek 4 is in ironing connection, a breathable part material sealing and ironing connecting part 7 is formed between the adhesive-coated Tyvek 4 and the first polyethylene film 1, the other side opposite to the bottom of the bag is a bag opening 5, and the edge of the adhesive-coated Tyvek 4, which is close to the bag opening 5, is used as a peeling opening 3. The packaging bag meets the requirements that sterilization factors can enter and separate out when the ethylene oxide is sterilized by using the gummed special strong material. The glued special guard material is a medical special Wei Jianggai material prepared by combining medical paper with medical glue in DuPont in the United states, and because the glued special guard material has higher cost, only a small part of the glued special guard material is generally used as a ventilation part to reduce the cost. However, the medical sterilization packaging bag needs to meet the requirement of safe opening while meeting sterilization, namely, the sterilization packaging bag needs to meet the requirement of safe opening when the sterilization packaging bag is opened for use after the sterilization of the instrument. Thus, the ventilation site is also the passage for opening the bag to remove the instruments from the bag. The glued special strength just meets the requirement that the glue has certain sealing and scalding strength after being sealed and scalded with polyethylene film material, and fiber paper scraps are not generated by easy stripping, but new problems are also derived at the same time.
In order to facilitate peeling and opening, and meet the requirement of taking out medical instrument articles, the ventilation part must be at one end of the sterilization packaging bag, namely the bag opening or bag bottom part, while any one end of the packaging bag needs to bear relatively large force relative to other parts of the packaging bag, but the peeling strength of the adhesive coating special guard and the polyethylene film seal is relatively low, and the phenomenon that the adhesive coating special guard seal is exploded easily occurs in the sterilization or transportation process, so that the sterilization fails; in addition, when the adhesive-coated special-shaped material is peeled off and opened, although the fiber-free paper scraps fall off, after the adhesive is coated on the adhesive-coated special-shaped material, the risk of pollution of products caused by the generation of the adhesive-free scraps is difficult to be avoided hundred percent, and meanwhile, the air permeability of the adhesive-coated special-shaped material is greatly reduced, so that the entering and exiting of sterilization factors are influenced.

Thus, the firmness of the bag bottom is greatly enhanced, the air permeability is increased, and the risk of pollution of articles during opening is reduced.
Therefore, the medical sterilizing and ventilating packaging bag provided by the utility model has the following advantages compared with the prior art:
1) The sealing and scalding strength of the bottom of the bag body is improved, the bottom of the bag is not exploded due to insufficient sealing and scalding fastness, and the risk of bag explosion is reduced;
2) The adhesive-coated special-shaped material is changed into a non-adhesive-coated special-shaped material, so that the cost consumed by adhesive coating is reduced, the original air permeability of the special-shaped material is maintained, and the better air permeability can bring convenience to the entry and the exit of sterilization factors;
3) When the plastic film is opened, the stripping and uncovering layer is stripped between the strippable and easy-uncovering polyethylene film and the polyethylene film, so that fiber paper scraps and glue scraps can not appear, and the risk of pollution to articles is reduced.
According to the utility model, the medical sterilization and ventilation packaging bag with good ventilation property, bag bottom firmness and high safety is provided, and the medical sterilization and ventilation packaging bag is particularly suitable for sterilization packaging of larger instruments and has wide application prospects in the field of sterilization packaging of medical instruments.
