Abstract
The utility model relates to a new layered material, in particular a layered polymer packaging material with high barrier for antibacterial liquid. The material is layered structure and divided into a polyolefin nanoparticles layer, a graft resin layer, a PA layer, a graft resin layer, a PVDC layer, a graft resin layer, a nanoparticles of polyolefin layer from outside to inside respectively. The utility model has the advantaged that the material solves the technical problem that the low-barrier of existing packaging film materials causes the short duration of the liquid packaging preservation and can be used in the medical field.
Description
Technical field:
The utility model relates to stratified material, particularly a kind of high-barrier of stratiform and antibacterial liquid packing High molecular material
Background technology:
Popular flexible package punch membraneous material is instant drink type or the plastic sheeting with certain barrier on the market now, and its Keeping life is short, must drink within 1～2 day or 30 days.The characteristic of further raising, especially resin that process technology of its individual layer to 3 layer and formula for a product have restricted barrier has determined that plastic sheeting is big to the permeability of air, so that is saved thing oxidation deterioration, breed bacteria.
General polyethylene liquid packaging film moisture peretrability is little, but the big (oxygen permeating amount 〉=2000ml/24hm of permeability to air
2Atm), grow bacterium and acidifying easily and make connection with wrapping of piece lose the fresh requirement of guaranteeing the quality, and the infiltration of oxygen also easily causes the oxidation deterioration of packing material.
The utility model content:
The utility model will solve existing flexible package punch membraneous material low-resistance every causing short technical matters of packaged fluid preservation phase.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of high-barrier and antibacterial liquid packing High molecular material, it is characterized in that: this material is a laminar texture, and it from outer to inner is divided into olefin polymerization nanometer stratum granulosum, graft resin layer, PA layer, graft resin layer, PVDC layer, graft resin layer, olefin polymerization nanometer stratum granulosum successively.
The arranged outside of this material laminar texture has olefin polymerization nanometer stratum granulosum, graft resin layer.
The inboard of this material laminar texture is provided with olefin polymerization nanometer stratum granulosum, graft resin layer.
The medial and lateral of this material laminar texture are respectively arranged with olefin polymerization nanometer stratum granulosum, graft resin layer.
Make by said structure and the utlity model has following technique effect:
The utility model high-barrier and antibacterial liquid are packed High molecular material, can apply to the packing of fresh milk.It can provide the shelf-life that often reaches 180 days (6 months), and this makes the green animal husbandry dairy products without pollution in area, off-lying province grassland pass through long distance transportation, near becoming possibility, guides the new trend of dairy products Flexible Package Market to super large urban consumption group.For advanced level user, according to its specific (special) requirements, we also can make it use in the clean field of medical height by adjusting prescription, to replace oldfashioned glass bottle and present PVC infusion bag, have solved the environmental issue of national attention.
Description of drawings:
Fig. 1 is the laminar texture scheme drawing of the utility model high-barrier and antibacterial liquid packing High molecular material.
Among the figure:
1-olefin polymerization nanometer stratum granulosum; 2-graft resin layer;
The 3-PA layer; 4-graft resin layer;
The 5-PVDC layer; 6-graft resin layer;
7-olefin polymerization nanometer stratum granulosum.
The specific embodiment:
See also Fig. 1, it is the laminar texture scheme drawing of the utility model high-barrier and antibacterial liquid packing High molecular material.As shown in the figure: this material is a laminar texture, and it from outer to inner is divided into olefin polymerization nanometer stratum granulosum 1, graft resin layer 2, PA layer 3, graft resin layer 4, PVDC layer 5, graft resin layer 6, olefin polymerization nanometer stratum granulosum 7 successively.
This high-barrier and antibacterial liquid packing High molecular material make blood slurry or other liquid descend energy fresh-keeping 90～180 days at normal temperature (6 ℃), prolong the value preserving phase more than 2 times more.The gordian technique of this product is to adopt the barrier (oxygen permeating amount≤30ml/24hm of the unique formula raising material of resins such as LDPE and MDPE or HDPE, mLLDPE, PA, EVOH, PVDC to gas
2Atm), and therein mixing nano level Ag and ZnO particle increases the antibacterial functions of material.Cooperate international advanced 7 layers, 9 layers even 12 layers of plastic sheeting co-extrusion process technology simultaneously, just can make performance-oriented membraneous material like this.
The inboard of this material laminar texture or arranged outside have olefin polymerization nanometer stratum granulosum, graft resin layer, and like this, material is altogether by 9 layers.
The medial and lateral of this material laminar texture are respectively arranged with olefin polymerization nanometer stratum granulosum, graft resin layer, and like this, material one has 11 layers.
The utility model carries out improved achievement at the disadvantage of common liq packing film just, and its special functionally more can use at high-end (as medical field) belong to the product of a new generation fully.
