Abstract
The utility model relates to a biaxially oriented polypropylene (BOPP) aluminum foil with polarity on both surfaces, which belongs to the technical field of the downstream processing of stretching polypropylene films in two directions; the BOPP aluminum foil with polarity on both surfaces comprises an upper surface layer, a core layer, a lower surface layer and an aluminum-plated corona layer which are sequentially composited from top to bottom, and the upper surface layer is a homo-polypropylene corona layer. According to the BOPP aluminum foil with polarity on both surfaces, the upper surface layer and the aluminum-plated corona layer are provided with polarity, so that printing, gluing and composition with other materials can be carried out directly on the two surfaces, so that the production of downstream clients is convenient, and the market share is expanded.
Description
Technical field
The utility model relates to a kind of two sides band polarity BOPP aluminizer, belongs to bidirectional stretching polypropylene film downstream processing technique field.
Background technology
Metallized film is compared the consumption that has significantly reduced aluminium with aluminium foil, saved the energy and material, has reduced cost; Have good folding resistance and good toughness simultaneously, become the NEW TYPE OF COMPOSITE film of a kind of function admirable, economy and beautiful appearance at present, replaced aluminum foil composite in many aspects.But also there is certain defective in existing metallized film: the face polarity of aluminizing after aluminizing weakens, and directly printing or gluing can't be realized on aluminium coated; The another side of metallized film does not have polarity.Therefore, the downstream client buys and to go back also need carry out corona treatment, makes its surface have polarity and is beneficial to following process (compound, printing, gluing etc.), increases client cost greatly.
Summary of the invention
In order to address the above problem, the utility model provides a kind of and can directly on two surfaces, print, gluing or carry out compound two sides band polarity BOPP aluminizer with other material.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of two sides band polarity BOPP aluminizer comprises from top to bottom compound successively upper epidermis, sandwich layer, following top layer, the corona layer of aluminizing, and wherein upper epidermis is a HOPP corona layer.HOPP corona layer is formulated by HOPP, antitack agent, and through corona treatment.Through the HOPP after the corona treatment, has stronger polarity.The corona layer of aluminizing has stronger polarity for the aluminium coated through corona treatment.
The thickness of said upper epidermis is 1 μ m, and the thickness of sandwich layer is 12-16 μ m, and the thickness on following top layer is 1 μ m, and the thickness of the corona layer of aluminizing is 400.
Said sandwich layer is the HOPP layer, is processed by 100% HOPP.
Said down top layer is the HOPP layer, and is formulated by HOPP, antitack agent, terpolymer.
A kind of two sides band polarity of the utility model BOPP aluminizer is compared with common aluminizer, and major advantage has:
1) need not follow-up corona treatment and just can on the upper epidermis and the corona layer of aluminizing, print, made things convenient for downstream clients' production, enlarge occupation rate of market;
2) owing to have stronger polarity on the corona layer of aluminizing, after its surface coating, can carry out compound with CPP, PE;
3) the shading performance of this two sides band polarity BOPP aluminizer is good, and metal luster is high, and the mechanical property of film is good.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; A kind of two sides band polarity of the utility model BOPP aluminizer comprises from top to bottom compound successively upper epidermis 1, sandwich layer 2, following top layer 3, the corona layer 4 of aluminizing, and wherein upper epidermis 1 is a HOPP corona layer; Sandwich layer 2 is the HOPP layer, and following top layer 3 is the HOPP layer.
The thickness of upper epidermis 1 is 1 μ m, and the thickness of sandwich layer 2 is 12-16 μ m, and the thickness on following top layer 3 is 1 μ m, and the thickness of the corona layer 4 of aluminizing is 400.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
Claims (4)
1. two sides band polarity BOPP aluminizer is characterized in that: comprise from top to bottom compound successively upper epidermis, sandwich layer, top layer, the corona layer of aluminizing down, wherein upper epidermis is a HOPP corona layer.
