Abstract
The utility model discloses a bag is moulded to medical sterilization wrapping paper, a serial communication port, including surface course (1) and bottom (2), surface course (1) and bottom (2) between interconnect airtight cavity (3) of placing the content with formation, the surface course make at dialyzing paper through the airblade coating by water base type EVA dispersion emulsion, the bottom make by polyethylene and polyester complex. The utility model discloses an analysis of the factor of sterilizing after the piercing through, having sterilized of the bag is moulded to medical sterilization wrapping paper when sterilization guarantee sterilization factor, heat -seal intensity has been ensured again: do not explode the bag when sufficient heat -seal intensity has ensured the sterilization, and satisfy the fungus nature that hinders that the apparatus shelf life deposited, more can satisfy medical environment device applications and open the clean dustless of when packing, reach the requirement that the cleaning was peeled off, make the medical instrument product not receive quadratic pollution, ensure safety.
Description
Technical field
The utility model relates to a kind of sterilization bag for medical applications technical field, and especially a kind of good permeability, cleaning are peeled off and hindered bacterium property notThe medical sterilization packaging paper plastic bag of quick-fried bag.
Background technology
The effect of medical sterilization packaging material is the packagings for medicine equipment series products, can carry out sterilizing to it, can carry out asepticOperation, can provide acceptable microorganism barrier property, before and after sterilizing can to product protect and sterilizing after can be regular oneIn limit, maintain the packaging system of internal system gnotobasis.
The paper plastic bag that medical device package industry is used now mainly contains two kinds: (1) adopts the dialyzing paper of EVA PUR grid gluingThe technique of+composite membrane is made, the bonding not firm easy quick-fried bag of paper plastic bag that coating quality is low, and the paper plastic bag gas permeability that coating quality is high is poor,May there is false envelope phenomenon simultaneously, while causing sterilizing packaging bag quick-fried rotten, make sterilizing failure. (2) adopt and be coated with solvent-borne type EVA heat-sealingThe technique of the dialyzing paper+composite membrane of glue, there is the difficult control of heat-sealing viscosity, the fastness that the paper plastic bag that coating quality is low hotly joins in this series productsNot, the paper plastic bag fastness that coating quality is high is enough, but gas permeability is poor, and easy waste paper while peeling off, causes the generation of paper scrap, reaches notTo clean requirement of peeling off; The contaminative of solvent is large in addition, not environmental protection, and coating is residual large.
Summary of the invention
The problem existing for prior art, the utility model provides a kind of good permeability, cleaning to peel off and hinders bacterium property not quick-fried bagMedical sterilization packaging paper plastic bag.
In order to address the above problem, the utility model by the following technical solutions:
A kind of medical sterilization packaging paper plastic bag, is characterized in that, comprises surface layer 1 and bottom 2, described surface layer 1 and bottom 2Between interconnect to form the closed cavity 3 of placed content thing, described surface layer passes through air knife by aqua type EVA dispersion emulsionA side that is coated on dialyzing paper 11 is made, and described bottom is by polyethylene 21 and polyester 22 is compound makes.
Preferably, on described surface layer 1, scribbling the one side of aqua type EVA interconnects with the polyethylene layer of bottom (21).
Preferably, described bottom is PET/PE composite membrane.
Preferably, described surface layer is connected by heat sealing with bottom.
Preferably, described surface layer is connected along its edge 4 at least in part with bottom.
Preferably, described surface layer or bottom are provided with at least one easily handle 6.
Preferably, described paper plastic bag is provided with chemical stain cue mark 5.
Further preferably, described chemical stain cue mark is printed on the opposite side of dialyzing paper.
Further preferably, described chemical stain cue mark is ethylene oxide sterilizing cue mark.
Preferably, to disperse newborn coating weight be 3g/m to described aqua type EVA2。
The beneficial effects of the utility model:
The utility model adopts air knife type coating process that water high-quality aqua type EVA dispersion emulsion is coated on dialyzing paper, is formed withThe dialyzing paper of heat-seal coating, then form with PET/PE composite membrane involution. Medical sterilization packaging paper plastic bag of the present utility model guarantee is gone outThe parsing of the penetrating of the sterilizing factor, the complete rear sterilizing factor of sterilizing when bacterium; Ensure again heat seal strength: enough heat seal strength guaranteesNot quick-fried bag when sterilizing, and meet the resistance bacterium property that the apparatus shelf-life deposits; More can meet medical environment Application of device opens while packagingCleaning dustless, reach the requirement that cleaning is peeled off, make medical device product not be subject to the pollution of secondary, ensure safety.

Detailed description of the invention
Medical sterilization of the present utility model packaging paper plastic bag, it comprises surface layer 1 and bottom 2, described surface layer 1 and bottom 2 itBetween interconnect to form the closed cavity 3 of placed content thing, wherein, surface layer 1 passes through gas by aqua type EVA12 dispersion emulsionCutter is coated on a side of dialyzing paper 11 and makes, and it is 3g/m that aqua type EVA disperses newborn coating weight2; Bottom 2 is by polyethylene (PE)Layer 21 and polyester (PET) layer 22 compound making. Surface layer scribbles the one side of aqua type EVA and the polyethylene layer of bottom (21) phaseConnect.
In preferred embodiment as described in Figure 1, surface layer 1 and bottom 2 connect by heat sealing along its edge 4 at least partlyConnect. Surface layer 1 is that water high-quality aqua type EVA dispersion emulsion is coated on by air knife type coating process in a side of dialyzing paper, formsHave the dialyzing paper of heat-seal coating, aqua type EVA dispersion emulsion is that device is produced in the internal plasticization of polyvinyl acetate emulsion, due at poly-acetic acidIn ethylene molecule, introduce ethylene molecule chain, made acetyl group produce discontinuity, increased the rotary freedom of macromolecular chain, skyBetween hinder littlely, it is soft that high polymer main chain becomes, and the migration of plasticizer can not occur, and ensured the permanent softness of product, to purpleOutside line has good stability, mixes and coacervation does not occur with multiple filler; Aqua type EVA and poly terephthalic acid second twoThe materials such as alcohol ester (PET) and polyethylene (PE) have fine heat sealing property; Aqua type EVA has solved solvent-borne type and heat molten type coatingMany puzzlements, ensure the porous of coating and the stability of coating and quality, have both ensured gas permeability and the firm intensity of heat-sealing, can reach againPeel off to cleaning.
