Primary sterilization packing valve bag in the market, basically all by each a slice paper or plastic film (monofilm or complex film) combine up and down, adopt the structure of front plastic film and back side paper, the periphery of paper and plastic film is bonded together, to constitute packaging bag.Such packing can satisfy the primary sterilization packaging bag must be possessed the microbial barrier function and can bear its sterilising conditions, but in the opening procedure of packing, can't guarantee the phenomenon that 100% no paper scrap produces.Because packaging bag simultaneously is a plastic film, one side is a paper, and two kinds of material heat seals should guarantee the involution fastness of heat seal together, does not have paper scrap when making peel-to-open again and produces, and this is the comparatively difficult problem of opposition that needs solution in sterilization packaging always.Existing technology is included in and is coated with thermosol on the paper, has avoided the direct heat seal of plastic film and paper like this, but the paper permeability to air of coating behind the thermosol has been subjected to very big influence.Change latticed gluing again into; Temperature tolerance that can this thermosol is relatively poor, in general sterilization process, the phenomenon of quick-fried bag all might occur; Occurred water soluble glue afterwards, the suitable of temperature had been enhanced.But no matter be hot melt glue, or water soluble glue, all have certain residual.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of Dispoable medical sterilization packaging valve bag is provided, and absolute no paper scrap fiber and particulate generation reduce contamination of heavy once more when opening.
In order to achieve the above object, technical scheme of the present invention is as follows:
Dispoable medical sterilization packaging valve bag comprises upper strata plastic film and lower floor's plastic film, and two-layer heat seal and has opening in a side together, its at the middle and upper levels plastic film have breather hole, the outside face of described upper strata plastic film also has one deck crimped paper.
Described upper strata plastic film and/or lower floor's plastic film are epoxy polyester (PET)+strippable complex films of polyethylene (PE).
Described crimped paper is medical crimped paper (ArjoWiggins), has taping certainly of the usefulness of sealing in the open side of plastic film.
Adopt the Dispoable medical sterilization packaging valve bag of this case of technology of the present invention, packing load-bearing effect is better, in the opening process of unpacking, does not definitely have paper scrap and produces, thereby reach safer unlatching.Can be widely used in the sterilization virus killing packing of medicine equipment, play the protective effect after the sterilization
Description of drawings
Fig. 1 is a Dispoable medical sterilization packaging valve bag structural representation of the present invention.
The specific embodiment
Below with reference to the accompanying drawings, provide preferred embodiment of the present invention, and described in detail, enable to understand better function of the present invention, characteristics.Dispoable medical sterilization packaging valve bag of the present invention is the packaging product that primary sterilization uses, and is applicable to sterilization methods such as epoxyethane and formaldehyde, can play the protective effect after the sterilization.
As shown in Figure 1, Dispoable medical sterilization packaging valve bag is made up of sheet two layers of material up and down, comprises upper strata plastic film 1 and lower floor's plastic film 2, and three lateral edges of upper strata plastic film 1 and lower floor plastic film 2 hotly join is in the same place, and what a side did not hotly join is its opening 3.
Its at the middle and upper levels plastic film 1 be equipped with breather hole in advance, the purpose that has breather hole on the plastic film is for ventilative, the turnover of the factor of being convenient to sterilize.The number of punching can be more as far as possible, but will guarantee the intensity of plastic film itself simultaneously, can not be too much.
The outside face of upper strata plastic film 1 also has one deck crimped paper 4.We have adopted medical crimped paper (ArjoWiggins) this crimped paper.On a plastic film, punch, with the plastic film of good especially crimped paper of permeability to air and punching altogether, so both solved the sealing strength of sack, solved the permeability to air problem again.Use such packing, secure context has been increased guarantee.
The material of upper strata plastic film 1 and lower floor's plastic film 2 both can be a monofilm, also can be complex film.Monofilm is exactly that this plastic film is made up of the mono-composition, as adopting as common polyethylene (PE) film.But the two-layer up and down valve bag that all is polyethylene (PE) film is made is peeling off between plastic film and the plastic film, is difficult to strip off usually.
Therefore we are designed to peelable film with lower floor of the present invention plastic film, promptly adopt the complex film of epoxy polyester (PET)+polyethylene (PE).Complex film is through the synthetic plastic film of certain processing technique by two or more material.Chang Yong peelable film great majority are PE in the market, so complex film is also used the complex film of PE.Have only two kinds of identical plastic films of material heat seal to process, meet the requirements of packaging bag otherwise can't make.Here alleged " peelable film ", just be meant in polyethylene (PE) lining and added some particular matters, its physical property is changed to some extent, again with epoxy polyester (PET) the composition complex film that combines, the character of the each side of this complex film can both satisfy the requirement of packing, and relative cost is also more moderate.Its effect is a peel-to-open of being convenient to valve bag, makes with strippable complex film and packs valve bag, even peeling off between plastic film and the plastic film also is easy to.
Lower floor's plastic film 2 is peelable complex films, and the side that does not promptly have crimped paper is the peelable composite bed of PET/PE, and the upper strata plastic film 1 that crimped paper is arranged is a PE film of having beaten the routine in hole.Certainly, also can adopt upper strata plastic film 1 and lower floor's plastic film 2 to be peelable film, be easier to open and peel off.
Upper strata plastic film 1 and crimped paper 4 be heat seal together, be to be penetrated on the paper after the nexine fusing with plastic film to be bonded together, use other any adhesives nothing but.Crimped paper has at the open side edge from taping 5, is used for sealing of packaging bag.
The one side of sterilization packaging bag of the present invention is the complex film of peelable PE, it is sir-tight window interface, and another side is the barrier that PE film punching back and crimped paper form uniqueness altogether, this two sides lumps together the form of making valve bag again, the sealing strength that had both had plastic bag, the permeability to air that has paper plastic bag again, and be again the film that is composited with special peelable PE, has strippable performance so again, when opening like this peeling off between the two layers of plastic film, never have the generation of paper scrap, thereby reach safer unlatching.Dispoable medical sterilization packaging valve bag is similar with other compares for this, the load-bearing effect of packing is better, product is widely used in the sterilization virus killing packing of medicine equipment, be applicable to sterilization methods such as epoxyethane, formaldehyde and ray, have very strong medium osmosis and bacterium barrier, the purpose that article in the bag are sterilized can be reached, the demand that the sterilization back stores the long period can be satisfied again.
The front provides the description of more detailed embodiment, so that any technical personnel in this area is understood the present invention.To this embodiment, those skilled in the art can make various modifications or conversion on the basis that does not break away from the principle of the invention.Be that every simple, equivalence of doing according to the claims and the description of the present patent application changes and modification, all fall into the claim protection domain of patent of the present invention.
