Abstract
The utility model discloses a polyethylene aluminum-coated composite film with metal luster of the diffuse reflection surface of an aluminum foil. The composite film comprises a function layer in the interior and an outer layer on the surface, wherein the function layer is a polyethylene aluminum-coated layer; the outer layer can be a biaxially oriented polypropylene layer, a polyester layer or a biaxially oriented nylon layer; a core layer is arranged between the function layer and the outer layer; and the core layer can be a polyethylene layer, an ethylene vinyl acetate copolymer layer, the polyester layer or the biaxially oriented nylon layer. The utility model further discloses a polyethylene aluminum-coated composite bag with metal luster of the diffuse reflection surface of the aluminum foil. The composite bag comprises a packaging film. The composite film or bag has the characteristics of very good metal luster of the diffuse reflection surface of the aluminum foil, high water resistance, high oxygen resistance, high composite strength, high aluminum-coated adhesion force, high stripping strength at the heat-seal part after the heat-seal treatment, low heat-seal temperature, good cost advantage and the like, and can be widely applied to the fields of food packaging, drug packaging, decoration, industrial product packaging and the like.
Description
Technical field
The utility model relates to and a kind ofly has aluminium foil diffuse surface metallic luster and contain composite membrane and the complex pocket that polyethylene is aluminized.
Background technology
Flexible package field worker makes minimization of cost and proprietaryization of performance and constantly develops various packaging material and mechanism, to satisfy different field client's demand in order to improve the outward appearance diversity of flexible package.
Aluminizer be adopt special process plastic sheeting plated surface last layer as thin as a wafer metallic aluminium and a kind of composite soft packaging material of forming, wherein the most frequently used processing method is when the vacuum aluminum-coated method of number, be exactly by high temperature, metallic aluminium to be melted evaporation under high vacuum state, the steam precipitation of aluminium is stacked on the plastic sheeting surface, thereby makes the plastic sheeting surface have metallic luster.Because it had both had the characteristic of plastic sheeting, have again the characteristic of metal, be a kind of attractive in appearance, function admirable, practical packaging material.
Use at present maximum metallized films and mainly contain polyester aluminizer (VMPET) and polypropylene aluminizer (VMCPP).The effect that film surface is aluminized is shading, resisting ultraviolet radiation, both extended the shelf-life of content, improved again the brightness of film, replaced to a certain extent aluminium foil, also has inexpensive, the attractive in appearance barrier property preferably that reaches, therefore, the application of aluminizer in composite packaging is very extensive, is mainly used at present that biscuit etc. is dry, in the external packing of dilated food packing and some medicine, cosmetics.
Existing aluminized complex film and complex pocket exist also that cost is high, combined strength bination is not high, the not high defective of heat seal strength.
The utility model content
The purpose of this utility model is for above-mentioned situation, provides a kind of and has aluminium foil diffuse surface metallic luster and contain composite membrane and the complex pocket that polyethylene is aluminized.
The purpose of this utility model realizes by following technical proposals:
A kind of have aluminium foil diffuse surface metallic luster and contain the composite membrane that polyethylene is aluminized, and comprises the skin on inner functional layer, surface, and described functional layer is the polyethylene aluminium coated.
As optimal way, described skin is the Biaxially oriented polypropylene layer.
As optimal way, described skin is polyester layer.
As optimal way, described skin is the biaxial tension nylon layer.
As optimal way, be provided with sandwich layer between described functional layer and skin.
As optimal way, described sandwich layer is polyethylene layer.
As optimal way, described sandwich layer is the ethylene-vinyl acetate copolymer layer.
As optimal way, described sandwich layer is polyester layer.
As optimal way, described sandwich layer is the biaxial tension nylon layer.
As optimal way, described complex pocket is made of above-mentioned packaging film.
The beneficial effects of the utility model are as follows:
The utlity model has extraordinary aluminium foil diffuse surface metallic luster; High water resistant performance and high oxygen resistance; High combined strength bination; The height adhesive force of aluminizing; Heat-sealing post heat-seal place high-peeling strength; Heat-sealing temperature is low; The good characteristics such as cost advantage.Can be widely used in the fields such as packaging for foodstuff, medicine packing, decoration, industrial goods packing.
The utlity model has with polypropylene aluminize VMCPP and polyester aluminize the same level of VMPET other block water and oxygen resistance.Also have simultaneously following characteristic:
1 appearance characteristics.Use composite soft packaging film of the present invention, bag, in non-printing place, have aluminium foil diffuse surface metallic luster.Appearance is very high-grade.
2 Cost Problems.A. the composite soft packaging that can see this appearance on present market can only use aluminium foil, but the cost of aluminium foil is very high, and not environmental protection, can't recycling.If flexible package uses this novel, cost is than original structure cost savings 10-30%.B. use the present invention, can replace the BOPP/VMPET/PE structure, be used for dried foods and light-weight packed, cost savings 20-40%.
3 compound peel strengths are high.Aluminize (VMCPP) with polypropylene relatively, aluminum transfer rate of the present invention is extremely low, has high combined strength bination characteristic.
4 heat-sealing post heat-seal place high-peeling strengths.Aluminize (VMCPP) with polypropylene relatively, aluminium coated of the present invention is very good in the peel strength at heat-sealing post heat-seal place, can not decay and improve on the contrary.Prevented that greatly the packing that causes because of the material delamination from destroying.
The balance of 5 heat-sealing temperatures and cost.With the polypropylene film material compared, polyethylene has lower rising and seals temperature, wider heat-sealing window, and its cost is lower than same level polypropylene film simultaneously.
