Description
Technical field:
The claimed technical scheme of the utility model belongs to the Multi-layer blown film flexible packing material, belongs to especially a kind of industrial goods inflation amortizing packaging material.
Background technology:
Along with the development of internet, this novel consumption pattern of shopping online and shopping idea are rooted in the hearts of the people, so and become the swiftest and the most violent field of development in consumer field.The thing of net purchase is multifarious, there is no lack of strange things, as long as you can be conceivable, substantially can find the seller on the net.Therefore, the arriving safely of net purchase product just becomes porcelain that focus, especially net purchase that everybody pays close attention to arrive, glassware, electronic product, small household appliances etc., can not be due to vibrations or scraping and damaged.So these manufactured goods must be used the protective package material.Be not the net purchase product in fact; any commodity in the modern life are before entering the final consumption link; usually all to pass through the links such as storage, transportation, sale; for avoiding article to be clashed in storage and transport process; usually clog some protectiveness materials in the space after the article vanning, as waste paper, plastics etc.Though can play like this buffering to a certain extent; but the inhomogeneities due to these material fillings; make it be difficult to provide uniform cushion effect to article on all directions; and these protectiveness materials were used namely and were abandoned; no longer reuse; therefore can cause environmental pollution, especially for instrument and the equipment of precision, it is unfavorable adopting this manner of packing.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of industrial goods inflation amortizing packaging material with remarkable protective buffering performance.
The technical scheme of the utility model technical solution problem: the protection of a kind of industrial goods is with the inflation amortizing packaging material, and this material is followed successively by polyamide and polyethylene coextruded film layer, three-layer co-extruded blow-molding polyethylene membrane layer (valve port film) from outside to inside.
Described polyamide and polyethylene coextruded film layer are followed successively by the first polyethylene layer, adhesive phase, aramid layer, adhesive phase, aramid layer, adhesive phase, the second polyethylene layer from outside to inside.
Preferred polyamide and polyethylene coextruded film layer are 13 μ m the first polyethylene layers, 4 μ m adhesive-layers, 6 μ m aramid layers, 4 μ m adhesive-layers, 6 μ m aramid layers, 4 μ m adhesive-layers, 13 μ m the second polyethylene layers from outside to inside.
Described aramid layer is total two-layer; the main gas barrier effect that plays excellence; prevent from filling in gas flush packaging the compression gas permeation; separately because may existing brilliant point, polyamide (PA) resin work in-process plastifies the problems such as bad; may cause gas to accelerate from the problem points seepage, thereby make the gas buffer material not have the effect of protection content.So we adopt two-layer aramid layer in project organization, can stop like this gas leakage risk that causes the local gas barrier to descend bringing due to brilliant some problem in materials processing, guarantee the obstruct validity of material gas.
Because polyamide (PA) does not belong to similar macromolecular material with polyethylene, intermolecular force is very little and can't form molecular chain action power between the two, so must reach excellent bond properties with the acidic-group graft polyolefin high molecular bonding resin two-layer generation chemical bond of bonding and physics winding performance, preferably use the blend in proportion of high-concentration acidic wastewater group binder resin and LLDPE, as jointing material between the two, prevent layers of material, cost is well controlled simultaneously.
Because the second polyethylene layer shields, must have excellent heat sealability and high low-temperature flexibility.
Described three-layer co-extruded blow-molding polyethylene membrane layer (valve port film) is followed successively by the first top layer, intermediate layer and the second top layer from outside to inside;
Preferential three-layer co-extruded blow-molding polyethylene membrane layer is followed successively by 10 μ m the first top layers, 20 μ m intermediate layers, 10 μ m the second top layers from outside to inside;
Described the first top layer, intermediate layer and the second top layer are take polyolefin elastomer as main, hp-ldpe is that auxiliary intermingling material forms, be take full advantage of the elastomeric self-adhesion of preferred polyolefm newly can and flexibility guarantee that the valve port film has the good gastight characteristics of tack under certain design, guarantee that fully the inflation padded coaming in the regular hour, does not produce the possibility of physics gas leakage after pouring compressed air.It is mainly to improve the film forming stability energy of polyolefin elastomer in extruding processing that formula adopts the hp-ldpe of a small amount of ratio of interpolation, suitably lowers simultaneously the self-adhesion of polyolefin elastomer, arrives the stability of the processability of bag operation after guaranteeing.
The utility model is considered from processing and the double-deck factor of OTR oxygen transmission rate, select polyamide (PA) as barrier layer, but polyamide (PA) and polyethylene (PE) can't be bonded together, so add adhesive phase bonding polyamide (NY) and polyethylene (PE), the two-layer polyamide of middle selection, be to consider when unpredictalbe problem such as brilliant point appears in one deck polyamide, can fully guarantee inflation performance with another layer.The film layer on both sides, the main heat-sealing effect that rises.
The utility model compared with prior art has good protective buffering performance, the characteristics of reverse leak-stopping performance.
