Abstract
The utility model discloses a degradable composite printing film which comprises a composite printing film body (1), wherein the composite printing film body (1) is formed by sequential lamination and co-extrusion of a printing layer (11), a core layer (12) and a back bottom layer (13). The degradable composite printing film is characterized in that the printing layer (11), the core layer (12) and the back bottom layer (13) are made of polyethylene oxide resin materials. According to the degradable composite printing film, the problem of environmental pollution due to the fact that existing composite printing films are made of polyethylene or polypropylene materials and cannot be degraded in the natural environment is effectively solved.
Description
Technical field
The utility model relates to plastic sheeting technical field, is specifically related to a kind of degradable printing compound film.
Background technology
Plastics package and plastic packet product shared share on market is increasing, particularly composite plastic flexible package, the fields such as food, medicine, chemical industry are widely used in, wherein again with packaging for foodstuff proportion maximum, such as beverage packaging, quick-frozen food packaging, cooking food packaging, fast food packaging etc., these products all bring great convenience to people's life.At present, printing compound film is mainly used in the printing of various food packs, also can use for normal tape film simultaneously, but on market, existing printing compound film is mostly made by polyethylene or polypropylene material, this material is hard degradation under natural environment, thereby environmental problem is produced to certain impact.
Summary of the invention
The utility model is for the problem of above-mentioned existence, a kind of degradable printing compound film has been proposed, the utility model efficiently solves existing printing compound film and is made up of polyethylene or polypropylene material, hard degradation in natural environment, thus cause the problem of environmental pollution.
The utility model is achieved through the following technical solutions:
A kind of degradable printing compound film, comprise printing compound film body (1), described printing compound film body (1) comprises printed layers (11), sandwich layer (12), back end layer (13), printed layers (11), sandwich layer (12), back end layer (13) superpose and are made by co-extrusion to successively, it is characterized in that: described printed layers (11), sandwich layer (12), back end layer (13) are made by peo resin material.
The further Technological improvement plan of the utility model is:
Described printing compound film body (1) thickness is 20 μ m, and wherein printed layers (11) thickness is 1 μ m, and sandwich layer (12) thickness is 16 μ m, and back end layer (13) thickness is 3 μ m.
The utility model compared with prior art, there is following obvious advantage, the utility model printing compound film adopts peo resin material to make, this material has one and has water-soluble and thermoplastic nonionic linear polymeric polymer, in contact oxygen atmosphere, be easy to degraded, thereby reduced problem of environmental pollution.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises printing compound film body 1, described printing compound film body 1 comprises printed layers 11, sandwich layer 12, back end layer 13, printed layers 11, sandwich layer 12, back end layer 13 superpose and are made by co-extrusion to successively, described printed layers 11, sandwich layer 12, back end layer 13 are made by peo resin material, and printing compound film body 1 thickness is 20 μ m, and wherein printed layers 11 thickness are 1 μ m, sandwich layer 12 thickness are 16 μ m, and back end layer 13 thickness are 3 μ m.
In sum, the utility model has reached foregoing invention object.
