Abstract
The utility model discloses a novel polypropylene film has corona layer, sandwich layer and the heat -seal layer of superpose in proper order, the corona layer is homopolymerization polypropylene layer, and the sandwich layer is for adding the homopolymerization polypropylene layer that has antistatic auxiliary agent, and the heat -seal layer is ternary random copolymerization polypropylene layer. This novel polypropylene film mainly provides reasonable institutional advancement to three -layer crowded altogether, and homopolymerization polypropylene, homopolymerization polypropylene and ternary random copolymerization polypropylene are adopted respectively to corona layer, sandwich layer and heat -seal layer, and the sandwich layer among this three adds moreover has antistatic auxiliary agent, has herein given polypropylene film excellent anti -static function, can use and use in the occasion of antistatic requirement, it is further originally novel still through reasonable structural design, make the film still have concurrently and be equipped with ultraviolet resistance and/or the antifog performance of person to this range of application of widening polypropylene film greatly.
Description
Technical field
The utility model relates to a kind of packing film, specifically refers to a kind of Novel polypropylene film.
Background technology
Polypropylene film is a kind of packaging bag material conventional at present, and it has high transparency, good thickness evenness, low-temperature heat-sealing, low cost and other advantages.The packaging material used at the product such as food, medicine at present mainly adopt polypropylene film, polyethylene film is according to use occasion, its various performance requirement is also not quite similar, such as be applied in the comparatively special packing of product, much require that packing film has antistatic lamp effect, base vinyl common at present easily accumulates electrostatic, cannot use with this in the occasion of antistatic requirement.
Utility model content
The purpose of this utility model is to provide a kind of Novel polypropylene film, and main imparting polypropylene film antistatic property, the occasion that can be applicable to antistatic requirement uses, and also can have other performances standby further concurrently, widen the range of application of polypropylene film with this.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of Novel polypropylene film, has stacked successively corona layer, sandwich layer and hot sealing layer; Corona layer is HOPP layer, and sandwich layer is the HOPP layer being added with antistatic auxiliary, and hot sealing layer is ternary atactic copolymerized polypropene layer.
The outside of described corona layer is also provided with uvioresistant layer.
The outside of described hot sealing layer is also provided with anti-fog layer.
After adopting such scheme, this Novel polypropylene film, mainly to three layers of co-extrusion, the improvement of rational structure is proposed, corona layer, sandwich layer and hot sealing layer adopt HOPP, HOPP and ternary atactic copolymerized polypropene respectively, and the sandwich layer in this three is added with antistatic auxiliary, impart the antistatic property of polypropylene film excellence in this, the occasion that can be applicable to antistatic requirement uses; Further basis is novel also by rational structural design, makes film also have standby uvioresistant and/or anti-fog performance concurrently, greatly widens the range of application of polypropylene film with this.

Fig. 1 is the structural representation of this Novel polypropylene film first embodiment;
Fig. 2 is the structural representation of this Novel polypropylene film second embodiment;
Fig. 3 is the structural representation of this Novel polypropylene film the 3rd embodiment.
Label declaration
Corona layer 1 sandwich layer 2
Hot sealing layer 3 uvioresistant layer 4
Anti-fog layer 5.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of Novel polypropylene film, as shown in Figure 1, has corona layer 1 stacked successively, sandwich layer 2 and hot sealing layer 3.
Corona layer 1 is HOPP layer, namely adopts the thin layer that HOPP material is made.Sandwich layer 2, for being added with the HOPP layer of antistatic auxiliary, namely adopts the thin layer that the HOPP material being added with (can be internal reference or laminar adhering mode) antistatic auxiliary is made.Hot sealing layer 3 is ternary atactic copolymerized polypropene layer, namely adopts the thin layer that ternary atactic copolymerized polypropene material is made.
This Novel polypropylene film, mainly to three layers of co-extrusion, the improvement of rational structure is proposed, corona layer 1, sandwich layer 2 and hot sealing layer 3 adopt homopolymerization material, homopolymerization material and ternary material respectively, and be especially only all added with antistatic auxiliary in sandwich layer 2 in this three, in making, this antistatic auxiliary can spread toward the corona layer 1 of both sides and hot sealing layer 3, impart the overall excellent antistatic property of polypropylene screen in this, can be applicable to the occasion separately with antistatic requirement.
Preferably, this Novel polypropylene film, as shown in Figure 2, is also provided with uvioresistant layer 4 outside corona layer 1.Isolate between this uvioresistant layer 4 and sandwich layer 2 and have corona layer 1, can not influence each other between both this, and make this Novel polypropylene film with excellent antistatic and uvioresistant effect.
Preferably, this Novel polypropylene film, is also provided with anti-fog layer in the outside of hot sealing layer 3, and this anti-fog layer and sandwich layer 2 isolation have hot sealing layer 3, can not influence each other between both this, and makes this Novel polypropylene film with excellent antistatic and anti-fog effect.
Preferably, this Novel polypropylene film, as shown in Figure 3, is also provided with uvioresistant layer 4, is also provided with anti-fog layer 5 in the outside of hot sealing layer 3 outside corona layer 1.Isolate between uvioresistant layer 4 and sandwich layer 2 and have corona layer 1, can not influence each other between both this; In like manner, anti-fog layer 5 and sandwich layer 2 isolation have hot sealing layer 3, can not influence each other between both this; Finally bring this Novel polypropylene film with excellent antistatic, uvioresistant and anti-fog effect.
The foregoing is only the preferred embodiment that this is novel, all equalizations done with this novel right change and modify, and all should belong to the scope of this novel claim.
Claims (3)
1. a Novel polypropylene film, has stacked successively corona layer, sandwich layer and hot sealing layer; It is characterized in that: corona layer is HOPP layer, sandwich layer is the HOPP layer that surperficial laminar is attached with antistatic auxiliary tunic, and hot sealing layer is ternary atactic copolymerized polypropene layer.
2. a kind of Novel polypropylene film as claimed in claim 1, is characterized in that: the outside of described corona layer is also provided with uvioresistant layer.
3. a kind of Novel polypropylene film as claimed in claim 1 or 2, is characterized in that: the outside of described hot sealing layer is also provided with anti-fog layer.
