Abstract
The invention relates to a medical sterilizing and packaging header bag and a preparation method thereof, belonging to an improvement on a process for processing a packaging material by using extrusion compound equipment in the flexible packaging industry and particularly belongs to an improvement on a process for processing a packaging material in the flexible packaging industry. The medical sterilizing and packaging header bag is prepared by scalding a breathable heat-sealing environment-friendly waterborne adhesive coated on a Dupont patented product Tyvek as a breathable material and a three-layer co-mixed polyethylene film prepared according to a special formula, so that the prepared packaging header bag has no film breaking when being stripped, has no secondary pollution risks, can completely meet the requirements of high resistance, good breathability, high tearing strength, puncture resistance, high moisture resistance and stripping cleanness and can also meet the requirements of packaging bags for sterilizing, storing and packaging second-class and third-class medical instruments.
Description
Technical field
The present invention relates to a kind of medical sterilization packaging top bag, relate to the improvement of Flexible-Packaging Industry to packing processing technology, in particular to a kind of method utilizing the polyethylene of modification to meet high-barrier sterilization of medical instrument and storage packaging operating needs.
Background technology
General product has the packaging bag of pure film class: pure film bag is made up of general high-molecular polythene, polyethylene is because of the non-isotactic of its molecular structure, puncture resistance and peel strength general, permeability to air extreme difference is unfavorable for penetrating of the sterilizing factor, be very large challenge to the validity of EO sterilizing and parsing, often sterilization effect difference toxic residue is large to adopt this packaging bag sterilizing; Be due to permeability to air extreme difference, the requirement that good permeability, high-tear strength, puncture resistance, high resistant are moist can not be met.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of medical sterilization packaging top bag and preparation method thereof.
For achieving the above object, the present invention by the following technical solutions:
A kind of medical sterilization packaging top bag, comprise gas permeable material, heat-sealable layer, barrier layer, described barrier layer comprises internal layer, interlayer, skin, and wherein internal layer, interlayer, skin all include and mix polyethylene film altogether.
Further, described gas permeable material is that Tyvek is coated with vapor-permeable type adhesives.
Further, Tyvek is that polythene material forms through flash spinning spray silk.
Further, described heat-sealable layer contains the copolymer emulsion of ethene-polyvinyl acetate.
Further, described mix altogether polyethylene film be with the addition of metallocene blended mix out mix polyethylene film altogether.
Further, the fusing point of described internal layer is 100 ~ 105 DEG C.
Further, the fusing point of described interlayer is 105 ~ 110 DEG C.
Further, described outer field fusing point is 110 ~ 120 DEG C.
Further, the interior poly-peeling force of packaging bag is 3 ~ 10N/15mm.
It is higher that this patent is applicable to cost, and two classes that risk is higher, three class medical device product are as the sterilizing of anesthesia packet, operation bag etc. and storage packaging.The task of this patent is a kind of packaging bag meeting the moist sterilization of medical instrument of high-barrier, good permeability, high-tear strength puncture resistance, high resistant and storage packaging and use of exploitation; The technical matters solved has: generally can meet epoxyethane, low temperature hydrogen peroxide plasma and the width penetrance according to sterilizing factor during sterilizing, after sterilizing, the sterilizing factor subtracts rare property; The high resistant bacterium property that the protection of transporting after ensureing apparatus sterilizing again and shelf-life deposit; More can meet cleaning when packaging is opened in medicine equipment application and not rupture of membranes, reach the requirement of clean stripping.Allow medical device product not by secondary pollution, ensure safety.This patent adopt Du Pont patented product Tyvek (spy defends by force) to be coated with vapor-permeable type to seal environment-friendly water-based adhesives be gas permeable material, then three layers that hotly join that proprietary formula makes are mixed polyethylene film altogether and form.Tyvek is that high-density polyethylene material forms through flash spinning spray silk, form network architecture and there is balanced physical property, not yielding, soft tough and tensile, anti tear, opaque, moisture proof, water resistant stain, skin friction force is little, elasticity is large, good permeability, resistance bacterium power is strong, combine the feature of paper, cloth and film, because Tyvek is high-density polyethylene material, open rotten film with after polyethylene film heat seal, the existing heat-sealing bonding of one deck, permeability to air need be done on Tyvek surface and can reach again clean environment-friendly adhesive coating process of peeling off.
The heat sealing agent that this patent is developed is the copolymer emulsion of ethene-polyvinyl acetate with different-grain diameter, aqueous dispersion environmental protection that heat seal strength is adjustable, this emulsion is made up of the particulate of different-grain diameter size, porous network structure is formed after coating, there is permeability, meet the requirement of this product, bond properties is by formula adjustment.
It is the new material that three layers of fusing point differs that this patent three layers of developing mix polyethylene film altogether, between lower 100 ~ 105 DEG C of internal layer fusing point, meets the operation requirements of medicine equipment producer packaging seal; Between two-layer interlayer 105 ~ 110 DEG C, between higher 110 ~ 120 DEG C of skin, meet internal layer firm involution when bag hotly joins, skin does not melt sticky equipment, ensure the continuity of production and meeting of properties of product, solve this technical barrier, develop three layers of different amount add metallocenes formula blended mix out specially mix polyethylene film altogether.
The present invention has following beneficial effect:
(1) heat seal strength >=3N/15mm of the product of this patent, and peeling off without rupture of membranes, the risk of non-secondary pollution, meets high-barrier completely, good permeability, high-tear strength, puncture resistance, high resistant is moist, the requirement of clean stripping; Also the requirement of the packaging bag that two higher classes of risk, three class sterilization of medical instrument and storage packaging use is met;
(2) permeability to air is strong, and sterilization effect table more, is resolved and remained without the property stayed completely; Moisture-resistant and water resistant stain by force, hinder bacterium excellent after sterilizing, ensure that preservation interval is pollution-free;
(3) puncture resistance and tear strength significantly promote.
