Abstract
The utility model discloses an anti-ultraviolet polyethylene membrane that is formed by coextrusion and compounding of an external layer, a middle layer and an internal layer; and the membrane surface of at least one layer of the external layer, the middle layer and the internal layer is provided with an anti-ultraviolet dispersion layer. By adopting the anti-ultraviolet dispersion layer, an anti-ultraviolet polyethylene membrane can be prevented from being damaged under the irradiation of ultraviolet, and can keep excellent use performance.
Description
Technical field
The utility model relates to the uvioresistant polyethylene film.
Background technology
Polyethylene film is as the hot sealing layer material in the packaging composite film commonly used, and it is little to have density, and the quality softness is easily sealed, advantages such as low cost.At present, on the market in order to guarantee the quality requirement of packing content thing, extend the shelf life, some sterilization measures are adopted in the capital, wherein adopt the mode of the ultraviolet disinfection that lethality is strong, efficient is high more and more to be accepted by people, but ultraviolet ray can damage the combination property that weakens film to the internal structure of polyethylene film in sterilization, influences the service life of film, shortens the shelf-life.
The utility model content
Technical problem to be solved in the utility model just provides a kind of polyethylene film that can resist the ultraviolet ray irradiation, does not influence the mechanical property and the service life of film.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of uvioresistant polyethylene film, it is characterized in that: described uvioresistant polyethylene film by outer, coextru-lamination is connected with internal layer in the middle level, in described skin, middle level, the internal layer at least the film surface of one deck be provided with the uvioresistant dispersion layer.
Preferably, described skin and internal layer are equipped with the uvioresistant dispersion layer by a side in middle level, are arranged on inside and are difficult for destroyed.
Preferably, the both sides in described middle level are equipped with the uvioresistant dispersion layer.Make to go up like this and all establish the uvioresistant dispersion layer than skin and internal layer by a side in middle level and simplify more and make things convenient for.
Preferably, described skin and middle level are formed by low density polyethylene (LDPE) and LLDPE, and described internal layer is made up of low density polyethylene (LDPE), LLDPE, metallocene linear-low density polyethylene and opening agent.
Uvioresistant polyethylene film of the present utility model makes polyethylene film can avoid sustaining damage under the ultraviolet ray irradiation by the interpolation of uvioresistant dispersion layer, keeps good serviceability.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation one of the utility model uvioresistant polyethylene film;
Fig. 2 is the structural representation two of the utility model uvioresistant polyethylene film.
The specific embodiment
As shown in Figure 1, be uvioresistant polyethylene film of the present utility model, described uvioresistant film is by skin 1, middle level 2 and internal layer 3 three-layer co-extruded being integral; Described outer 1 and middle level 2 form by low density polyethylene (LDPE) and LLDPE; Described internal layer 3 is made up of low density polyethylene (LDPE), LLDPE, metallocene linear-low density polyethylene and opening agent; In described outer 1, middle level 2, the internal layer 3 at least the film surface of one deck be provided with uvioresistant dispersion layer 4.
As Fig. 2, the film surface that the auxiliary agent of uvioresistant described in the utility model is dispersed in described skin, middle level or internal layer forms uvioresistant dispersion layer 4.Concrete, the both sides that described skin and internal layer lean on a side in middle level to be equipped with uvioresistant dispersion layer 4 or described middle level are equipped with uvioresistant dispersion layer 4.
Claims (3)
1. uvioresistant polyethylene film, it is characterized in that: described uvioresistant polyethylene film by outer (1), middle level (2) coextru-lamination is connected with internal layer (3), in described skin, middle level, the internal layer at least the film surface of one deck be provided with uvioresistant dispersion layer (4).
2. according to the described uvioresistant polyethylene film of claim 1, it is characterized in that: described skin and internal layer are equipped with the uvioresistant dispersion layer by a side in middle level.
3. according to the described uvioresistant polyethylene film of claim 1, it is characterized in that: the both sides in described middle level are equipped with the uvioresistant dispersion layer.
