Abstract
The utility model relates to a film. The film is characterized by comprising a first sandwich layer at the top, wherein an inner sandwich layer is arranged on the lower side of the first sandwich layer; and a second sandwich layer is arranged on the lower side of the inner sandwich layer. The film is simple in structure, easy to manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of film, particularly a kind of CPP film.
Background technology
Film is a kind of thin and soft transparent sheet.Process with plastics, adhesive, rubber or other materials, more existing films all are to use raw material production, waste a large amount of raw materials like this, and production cost is high, particularly heat-sealing film.
Summary of the invention
The purpose of the utility model is to provide a kind of film, and this membrane structure is simple, makes simple and easyly, and cost is low.
The utility model is characterised in that: a kind of film is characterized in that: comprise first interlayer at top, the said first interlayer downside is provided with intraformational bed, and said intraformational bed downside is provided with second interlayer.
Further, the corona layer of first interlayer for processing by corona layer PP Pipe Compound, said intraformational bed is the polypropylene interlayer that has the polypropylene leftover pieces to process, the hot sealing layer of said second interlayer for being processed by the heat sealability plastics.
The advantage of the utility model: simple in structure, to make simple and easyly, cost is low, low-carbon environment-friendly.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Among the figure: 1 is first interlayer; 2 is intraformational bed; 3 is second interlayer.
The specific embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and cooperates appended graphic elaborating as follows.
With reference to legend, a kind of film is characterized in that: comprise first interlayer 1 at top, said first interlayer, 1 downside is provided with intraformational bed 2, and said intraformational bed 2 downsides are provided with second interlayer 3.
Among the embodiment one:
First interlayer is used as the corona layer, selects corona layer PP Pipe Compound for use, and intraformational bed is selected the polypropylene leftover pieces of recovery for use, and second interlayer selects for use the heat sealability plastics to be used as hot sealing layer, can produce the compound heat-sealing film of cost high-quality low, that do not have waste material.
Among the embodiment two:
First interlayer is selected heat sealable plastics for use, and it is carried out corona treatment, and intraformational bed is selected the polypropylene leftover pieces of recovery for use, but second interlayer is selected the plastics of low-temperature heat-sealing for use, can produce that cost is low, the compound heat-sealing film of the high-quality two-sided heat-sealing that do not have waste material.
Among the embodiment three:
Intraformational bed can be selected filler (like calcium carbonate, talcum powder) or degradation plastic (like starch) for use, not only can produce the lower but also degradable opaque CPP film of cost.
The utility model can be according to the demand in market, and different collocation can produce the film of high-quality, and cost is low, and no waste material produces, and environmental protection.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
