Description
Technical field
The utility model relates to the packing film that a kind of macromolecular material is made, particularly a kind of film for blister package for packing medical equipment and high temperature resistant sterilization.
Background technology
Medical equipment is very high to the requirement of packaging material; except need satisfy the basic packaging character such as conventional protection and isolated external environment; more emphasize continuation, the stability of material property, and by sterilization require to extend and come with the adaptability of sterilization method, microorganism barrier and the avirulence of material.
The medical equipment sterilization packaging belongs to the flexible package category take the paper material as main body.The better packing method of generally acknowledging at present be first with the plastic uptake film that meets medical standard through melting, by the concrete shape plastics sucking moulding of medical equipment, put into after various medical equipments and the dialyzing paper heat-sealing, the finished product after then encapsulating is sterilized.
The medical equipment of generally using is now produced in the cleaning shop usually, however, before dispatching from the factory, its packing still must thoroughly sterilize, the most frequently used method of sterilization for the medical equipment after packing is high-temperature sterilization, namely spend left and right high-temperature sterilization 30 minutes 131, perhaps be penetrated into oxirane and kill bacterium residual on medical equipment in film.Put in ethylene oxide sterilizing cabinet fully sterilization, because the penetration of oxirane is very strong, can be penetrated into the dialyzing paper the inside and kills bacterium on medical equipment, the pernicious gas after killing bacteria can volatilize away by the pore in dialyzing paper again.Wherein said dialyzing paper is by the wood pulp manufacturing, the longer permeability of paper fiber is better, air can freely pass in and out, so residual oxirane toxic gas can discharge at leisure, but the unholiness thing such as bacterium, dust can't pollute sterilized medical equipment by dialyzing paper, so reach and can kill the bacterium on medical equipment after packing, and when operation is used without the residual purpose of oxirane pernicious gas.But, the dialyzing paper that generally uses at present both at home and abroad, the heat sealability of itself and above-mentioned blister plastic packaging film is bad, and must be coated with one deck PUR on dialyzing paper increases its heat sealability.But after being coated with one deck PUR on dialyzing paper, equal major part is played chemosmotic paper fiber hair hole plug, the penetration of dialyzing paper descends like this, makes oxirane infiltration difficulty, sterilize not thorough, and the discharge of pernicious gas is also very difficult; Also there is the difficult problem of toxicity migration in PUR simultaneously, also has potential safety hazard.(131 ℃, 30min) the packing film performance easily changes, and the packing film dimensional stability occurs relatively poor, seal the wider remaining limit problem such as more serious that bounces back and use high-temp steam sterilizing.
In addition, when raising the plastic uptake film of external packing and dialyzing paper, because intermembranous peel strength is very high, there is the paper scrap phenomenon in medical supplies in use after pushing aside.
For above problem, development of new medical equipment packing is necessary with the plastic uptake film.
The utility model content
For overcoming deficiency of the prior art, the purpose of this utility model is to provide the packing plastic uptake film that combination property still can well keep after a kind of excellent combination property, particularly high-temperature sterilization.
Sandwich construction is often favored because having multiple performance concurrently.Representational sandwich construction is that every one deck all has special characteristic, and this structure can be used to preparation packing plastic uptake film.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the utility model provides a kind of medical equipment packing plastic uptake film, form from material and be divided into seven-layer structure, from top to down, ground floor are hot sealing layer 1, and its composition is: the block copolymer of polypropylene and polyisobutene; The second layer is internal layer 2 for the first time, and its composition is: polypropylene block copolymer; The 3rd layer is internal layer 3 for the second time, and its composition is: HOPP; The 4th layer is the first adhesive linkage 4, and its composition is: the polypropylene of modified by maleic acid anhydride graft; Layer 5 is barrier layer 5, and its composition is: nylon copolymer; Layer 6 is the second adhesive linkage 6, and its composition is: the polypropylene of modified by maleic acid anhydride graft; Layer 7 is weathering layer 7, and its composition is: the copolymer nylon material, it is by making with amorphous nylons and the anti-stick nylon copolymerization that connects the master batch modification.
Preferably, described packing plastic uptake film, wherein said hot sealing layer 1 use polypropylene is metallocene polypropylene, described metallocene polypropylene and the polyisobutene addition in described hot sealing layer 1 mixture is 35%～50%.
Preferably, described packing plastic uptake film, the addition of wherein said amorphous nylons in described weathering layer 7 mixtures is 10%～20%; The described anti-stick even addition of master batch in described weathering layer 7 mixtures is 0.5%～2%.
preferably, described packing plastic uptake film, the thickness of wherein said hot sealing layer 1 accounts for described packing 15%～20% of plastic uptake overall film thickness, the thickness of described internal layer for the first time 2 accounts for described packing 10%～20% of plastic uptake overall film thickness, the thickness of described internal layer for the second time 3 accounts for described packing 10%～20% of plastic uptake overall film thickness, the thickness of described the first tack coat 4 accounts for described packing 5%～10% of plastic uptake overall film thickness, the thickness of described barrier layer 5 accounts for described packing 10%～15% of plastic uptake overall film thickness, described the second tack coat 6 thickness account for described packing 5%～10% of plastic uptake overall film thickness, described weathering layer 7 thickness account for described packing 10%～15% of plastic uptake overall film thickness.
The disclosed packing of the utility model plastic uptake film, its weathering layer 7 use copolymer nylon materials make packing with the vitrification point of plastic uptake film higher than 131 ℃, thereby can avoid the adhesion of make-up room after plastic uptake film high-temperature sterilization and the retraction problems of hot edge seal; Secondly, contain polyisobutene in described hot sealing layer 1 material composition, make the heat seal strength of involution between described plastic uptake film and dialyzing paper be stablized, even obviously do not descend after high-temperature sterilization yet, and make the fissility of plastic uptake film and dialyzing paper improve, very smooth between two-layer when peeling off, can not produce paper scrap.
The medical equipment packing that the utility model provides is more aobvious stable with the existing plastic uptake film performance of plastic uptake film, and particularly after high-temperature sterilization, its combination property still can be stablized maintenance.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below will enumerate specific embodiment of the utility model and coordinate accompanying drawing to be elaborated.
