Abstract
The invention discloses a paper-plastic packing bag for medical sterilization. The paper-plastic packing bag for medical sterilization is characterized by comprising a surface layer (1) and a base layer (2), wherein the surface layer (1) is connected with the base layer (2) to form a closed cavity (3) for placing contents; the surface layer is formed by coating water-based EVA dispersion emulsion on a piece of dialyzing paper by using an air knife; the base layer is made from a polyethylene and polyester composite film. The paper-plastic packing bag for medical sterilization, disclosed by the invention, can be used for guaranteeing penetration of sterilization factors during sterilization and disintegration of the sterilization factors after the sterilization is ended and is also used for guaranteeing the heat sealing strength; enough heat sealing strength can guarantee no bag explosion during sterilization, satisfy the bacteria resistance of instruments during storage within the guarantee period and further guarantee cleanness and no dust when the pack of an instrument in a medical environment is opened; therefore the requirement of clean removal can be satisfied, medical instrument products are prevented from secondary pollution, and safety is guaranteed.
Description
Technical field
The present invention relates to a kind of sterilization bag for medical applications technical field, especially a kind of good permeability, the clean medical sterilization packaging paper plastic bag peeled off and hinder the not quick-fried bag of bacterium property.
Background technology
The effect of medical sterilization packing is the packagings for medicine equipment series products; sterilizing can be carried out to it; sterile working can be carried out; acceptable germ barrier property can be provided, can protect product before and after sterilizing and the packaging system of internal system gnotobasis after sterilizing, can be maintained within certain time limit.
The paper plastic bag of present medical device package industry mainly contains two kinds: (1) adopts the technique of the dialyzing paper+complex film of EVA hot-melt adhesive grid gluing to make, the paper plastic bag bonding loosely easy quick-fried bag that coating quality is low, the paper plastic bag poor air permeability that coating quality is high, false envelope phenomenon may be there is simultaneously, when causing sterilizing, packaging bag is quick-fried rotten, makes sterilizing failure.(2) technique of the dialyzing paper+complex film being coated with solvent-borne type EVA heat-seal adhesive is adopted, there is heat-sealing viscosity difficulty and control in this series products, the fastness that the paper plastic bag that coating quality is low hotly joins is inadequate, the paper plastic bag fastness that coating quality is high is enough, but poor air permeability, and easy waste paper when peeling off, cause the generation of paper scrap, the requirement that out of reach cleaning is peeled off; The contaminative being solvent is again large, and not environmentally, coating is residual large.
Summary of the invention
For prior art Problems existing, the invention provides a kind of good permeability, the clean medical sterilization packaging paper plastic bag peeled off and hinder the not quick-fried bag of bacterium property.
In order to solve the problem, the present invention by the following technical solutions:
A kind of medical sterilization packaging paper plastic bag, it is characterized in that, comprise surface layer 1 and bottom 2, the closed cavity 3 forming placed content thing is interconnected between described surface layer 1 and bottom 2, described surface layer is made up by the side of airblade coating at dialyzing paper 11 of aqua type EVA dispersion emulsion, and described bottom is made up of polyethylene 21 and polyester 22 compound.
Preferably, the polyethylene layer (21) of the one side and bottom that described surface layer 1 scribble aqua type EVA is interconnected.
Preferably, described bottom is PET/PE complex film.
Preferably, described surface layer is connected by heat sealing with bottom.
Preferably, described surface layer and bottom are connected along its edge 4 at least in part.
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, described aqua type EVA disperses newborn coating weight to be 3g/m
2.
Beneficial effect of the present invention:
The present invention adopts air knife type coating process that water high-quality aqua type EVA dispersion emulsion is coated with exhibition on dialyzing paper, is formed with the dialyzing paper of heat-seal coating, then forms with PET/PE complex film involution.The parsing of the penetrating of the sterilizing factor, sterilizing complete rear sterilizing factor when medical sterilization of the present invention packaging paper plastic bag ensures sterilizing; Ensure again heat seal strength: not quick-fried bag when enough heat seal strengths have ensured sterilizing, and meet the resistance bacterium property that the apparatus shelf-life deposits; Cleaning when more can meet medical environment Application of device unlatching packaging is dustless, reaches clean requirement of peeling off, and makes medical device product by the pollution of secondary, ensures safety.

Detailed description of the invention
Medical sterilization packaging paper plastic bag of the present invention, it comprises surface layer 1 and bottom 2, the closed cavity 3 forming placed content thing is interconnected between described surface layer 1 and bottom 2, wherein, surface layer 1 is made up by the side of airblade coating at dialyzing paper 11 of aqua type EVA12 dispersion emulsion, and aqua type EVA disperses newborn coating weight to be 3g/m
2; Bottom 2 is made up of polyethylene (PE) layer 21 and polyester (PET) layer 22 complex film.The polyethylene layer (21) of one side and bottom that surface layer scribbles aqua type EVA is interconnected.
In preferred embodiment as described in Figure 1, surface layer 1 is connected along its edge 4 by heat sealing at least partly with bottom 2.Surface layer 1 is that water high-quality aqua type EVA dispersion emulsion is coated on the side of dialyzing paper by air knife type coating process, be formed with 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, owing to introducing ethylene molecule chain in polyvinyl acetate molecule, acetyl group is made to produce discountinuity, add the rotary freedom of macromolecular chain, steric restriction is little, high polymer main chain becomes soft, and can not the migration of plasticizer be there is, ensure that the permanent softness of product, good stability is had to ultraviolet, mix with multiple filler and coacervation does not occur, aqua type EVA and the material such as polyethylene terephthalate (PET) and polyethylene (PE) have fine heat sealing property, aqua type EVA solves many puzzlements of solvent-borne type and heat molten type coating, ensures the porosity of coating and the stability of coating and quality, has both ensured permeability to air and the firm intensity of heat-sealing, and can reach again clean and peel off.
PET+PE complex film is that pet layer 22 is formed by melting co-extrusion with PE layer 21 or pet layer 22 is bonded by other composite materials (as adhesive) with PE layer.PET+PE complex film is a kind of polymeric membrane that can adapt to and meet multiple sterilization method and hotly join bag technique.Polyethylene terephthalate (PET) and polyethylene (PE) and EVA have good heat sealing property.In addition, PET+PE complex film transparent visual, can by transparent underlayer 2 observe directly be contained in closed cavity 3 by the medicine equipment of sterilizing, facilitate medical personnel to use.Medical sterilization packaging paper plastic bag is provided with at least 1 chemical stain cue mark 5, is convenient to after sterilization process completes, confirms the validity of sterilization process, guarantee that sterilization effect meets the requirements.Chemical stain cue mark 5 is printed on the opposite side of the dialyzing paper at medical sterilization packaging paper plastic bag.
Surface layer 1 or bottom 2 can be provided with the easy handle 6 of nick shaped, to open the package time easy to use.
