Abstract
The utility model discloses a novel polyethylene film has heat -seal layer, sandwich layer and the corona layer of superpose in proper order, the heat -seal layer is for adding the metallocene polyethylene layer that has the ultraviolet resistance auxiliary agent, and the sandwich layer is for adding the linear low density polyethylene layer that has the ultraviolet resistance auxiliary agent, and the corona layer is for adding the low density polyethylene layer who has the ultraviolet resistance auxiliary agent. This novel polyethylene film mainly provides reasonable combination to three -layer crowded altogether and improves, and metallocene polyethylene, linear low density polyethylene and low density polyethylene material are adopted respectively to heat -seal layer, sandwich layer and corona layer, and this three all adds moreover has the ultraviolet resistance auxiliary agent, has herein given polyethylene film excellent ultraviolet resistance performance, and is applicable in the various occasions that need ultraviolet resistance. It is further, still in rationally designing the antistatic layer between the thin layer to it still has good anti -static function to give polyethylene film.
Description
Technical field
The utility model relates to a kind of packing film material, specifically refers to a kind of novel polyethylene films.
Background technology
Polyethylene film is a kind of packaging bag material conventional at present, and it has high transparency, good thickness evenness, easily heat-sealing, low cost and other advantages.Polyethylene film, according to use occasion, is also not quite similar to its various performance requirement, such as, be applied in the packing of product such as medicine, cosmetics of everyday use, much requires that packing film has uvioresistant effect, and base vinyl common is at present difficult to reach this requirement.
Utility model content
The purpose of this utility model is to provide a kind of novel polyethylene films, and main imparting polyethylene film uvioresistant effect, is applicable to anti-ultraviolet various occasion.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of novel polyethylene films, has hot sealing layer stacked successively, sandwich layer and corona layer; Hot sealing layer is the metallocene polyethylene layer being added with uvioresistant auxiliary agent, and sandwich layer is the linear low density polyethylene layer being added with uvioresistant auxiliary agent, and corona layer is for being added with the low density polyethylene layer of uvioresistant auxiliary agent.
Also antistatic layer is provided with between described hot sealing layer and sandwich layer.
Described sandwich layer and corona interlayer are also provided with antistatic layer.
The lateral surface of described hot sealing layer is also attached with anti-fog layer.
The lateral surface of described hot sealing layer is also attached with anti-fog layer, and described sandwich layer and corona interlayer are also provided with antistatic layer.
After adopting such scheme, this novel polyethylene films, mainly reasonably improvement is combined to three layers of proposition of co-extrusion, hot sealing layer, sandwich layer and corona layer adopt metallocene PE, LLDPE and low-density polyethylene material respectively, and this three is all added with uvioresistant auxiliary agent, impart the anti-ultraviolet property of polyethylene film excellence in this, be applicable in the anti-ultraviolet occasion of various needs.Further, also reasonable design antistatic layer between thin layer, thus imparting polyethylene film also has excellent antistatic property.

Fig. 1 is the structural representation of this novel polyethylene films first embodiment;
Fig. 2 is the structural representation of this novel polyethylene films second embodiment;
Fig. 3 is the structural representation of this novel polyethylene films the 3rd embodiment.
Label declaration
Hot sealing layer 1 sandwich layer 2
Corona layer 3 antistatic 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 polyethylene films, as shown in Figure 1, has hot sealing layer 1 stacked successively, sandwich layer 2 and corona layer 3.
Hot sealing layer 1, for being added with the metallocene polyethylene layer of uvioresistant auxiliary agent, namely adopts the thin layer that the metallocene polyethylene material being added with (can be internal reference or adhering mode) uvioresistant auxiliary agent is made.
Sandwich layer 2, for being added with the linear low density polyethylene layer of uvioresistant auxiliary agent, namely adopts the thin layer that the LLDPE being added with (can be internal reference or adhering mode) uvioresistant auxiliary agent is made.
Corona layer 3, for being added with the low density polyethylene layer of uvioresistant auxiliary agent, namely adopts the thin layer that the low density polyethylene (LDPE) being added with (can be internal reference or adhering mode) uvioresistant auxiliary agent is made.
This novel polyethylene films, mainly reasonably improvement is combined to three layers of proposition of co-extrusion, hot sealing layer 1, sandwich layer 2 and corona layer 3 adopt metallocene PE, LLDPE and low-density polyethylene material respectively, and this three is all added with uvioresistant auxiliary agent, impart the anti-ultraviolet property of polyethylene film excellence in this, be applicable in the anti-ultraviolet occasion of various needs.
Preferably, this novel polyethylene films, is also provided with antistatic layer in the side of sandwich layer 2 or both sides, and namely this antistatic layer is folded between hot sealing layer 1 and sandwich layer 2, and/or be folded between sandwich layer 2 and corona layer 3, make this novel polyethylene films also have excellent antistatic effect with this.
Preferably, this novel polyethylene films, as shown in Figure 2, is also attached with anti-fog layer 5 on the lateral surface of hot sealing layer 1.This anti-fog layer 5 is positioned at innermost layer, and when packing damp and hot product, packaging bag internal layer can not form mist, and product will be made putrid and deteriorated because of water droplet, also promotes presentation effect simultaneously.
Preferably, this novel polyethylene films, as shown in Figure 3, is also attached with anti-fog layer 5 on the lateral surface of hot sealing layer 1, is also provided with antistatic layer 4 between sandwich layer 2 and corona layer 3 simultaneously.Isolate between this anti-fog layer 5 and antistatic layer 4 have hot sealing layer 1 and sandwich layer 2 two-layer, can not influence each other between both this, and make this novel polyethylene films with excellent antifog, antistatic and uvioresistant 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.
