Abstract
The invention discloses a film, and relates to the field of packaging supplies. The film comprises an anti-static layer, a supporting layer and a porous layer, wherein the upper portion of the supporting layer is bonded with the anti-static layer, the supporting layer is made of HDPE, and the porous layer is arranged under the supporting layer and composed of a plurality of small holes which are uniform in size and evenly distributed in a rectangular matrix mode. The film has the advantages that the film is provided with the anti-static layer which can effectively prevent pollution caused by dust and small solid particles absorbed to the surface layer of the film due to the static attraction force action; meanwhile, the porous layer is arranged, not only has the effects of sound insulation and silencing, but also has an air permeability function. The film is environmentally friendly, high in practicability, wide in application range and worthy of popularization.
Description
Technical field
The present invention relates to package packing supplies field, particularly relate to a kind of film.
Background technology
The regulation that the assortment of film is ununified.The mode classification of usual people's custom has following three kinds: (1) by the raw materials used classification of film forming: have polyethylene foil, polypropylene film, polyvinyl chloride film and mylar etc.(2) classify by thin film application: have agricultural film (here according to the concrete purposes of plastic sheeting for farm use, mulch film and awning film can be divided into again); Packing film (packaging film by its concrete purposes, food package film and various industrial product packaging films etc. can be divided into again) and for particular surroundings, the breathable films with special purpose, water-soluble film and there is the film etc. of piezoelectric property.(3) classify by the forming method of film: the film having extrusion plasticizing, then blow molding, is called blown film; Through extrusion plasticizing, then melting charge is from the film of mould mouth flow casting molding, is called cast film; The film that flattening mill is made up of several roller spreadings plasticizing raw materials, be called calendered film, if Chinese application number is that CN 103519659 A discloses a kind of light reflecting membrane, comprise High molecular material body, described light reflecting membrane also comprises coating structure, and described coating structure is coated on a face of High molecular material body, but, the film of this technology does not have good electrostatic prevention and sound insulation soundproof effect, and structure is also more single.
Summary of the invention
The object of the present invention is to provide a kind of film, to solve the above-mentioned multinomial defect caused in prior art.
A kind of film, comprise antistatic backing, supporting layer and porous layer, antistatic backing is bonded with above described supporting layer, supporting layer is made up of HDPE material, described porous layer is arranged on below supporting layer, described porous layer is made up of several uniform apertures, and rectangular array format is evenly arranged, and the thickness of described porous layer is 10-20 μm.
Preferably, described antistatic backing is made up of anti-static coatings and PMMA plate, and anti-static coatings sticks on PMMA plate equably.
Preferably, described supporting layer is made up of pc or pvc, and thickness is 30-50 μm.
Preferably, the aperture of described aperture is 100-200 nm.
The invention has the advantages that: film is provided with antistatic backing, antistatic backing is made up of anti-static coatings and PMMA plate, anti-static coatings sticks on PMMA plate equably, not only structure comparison is stable for the antistatic backing of this technology, also a saving raw material, economic and practical is strong, effectively can prevent the pollution caused because electric attraction effect causes film top layer attract dust and solid granule, simultaneously, also be provided with porous layer, porous layer not only has the effect that sound insulation is eliminated the noise, permeation functions can also be played, this film is environmental protection, the film that practicality is stronger, applied widely, be worthy to be popularized.

Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
As depicted in figs. 1 and 2, a kind of film, comprise antistatic backing 1, supporting layer 2 and porous layer 3, antistatic backing 1 is bonded with above described supporting layer 2, supporting layer 2 is made up of HDPE material, described porous layer 3 is arranged on below supporting layer 2, described porous layer 3 is made up of several uniform apertures 31, rectangular array format is evenly arranged, the thickness of described porous layer 3 is 10-20 μm, film is provided with antistatic backing 1, antistatic backing 1 is made up of anti-static coatings 11 and PMMA plate 12, anti-static coatings 11 sticks on PMMA plate 12 equably, not only structure comparison is stable for the antistatic backing 1 of this technology, also a saving raw material, economic and practical is strong, effectively can prevent the pollution caused because electric attraction effect causes film top layer attract dust and solid granule, simultaneously, also be provided with porous layer 3, porous layer 3 not only has the effect that sound insulation is eliminated the noise, permeation functions can also be played, this film is environmental protection, the film that practicality is stronger, applied widely, be worthy to be popularized.
It should be noted that described electrostatic prevention, 1 is made up of anti-static coatings 11 and PMMA plate 12, and anti-static coatings 11 sticks on PMMA plate 12 equably, and not only structure comparison is stable for the antistatic backing 1 of this technology, and also a saving raw material, economic and practical is strong.
In addition, described supporting layer 2 is made up of pc or pvc, and thickness is that 30-50 μm, pc or pvc have certain modulus of elasticity, not yielding, and design comparison is reasonable, durable in use.
Based on above-mentioned, film is provided with antistatic backing 1, antistatic backing 1 is made up of anti-static coatings 11 and PMMA plate 12, anti-static coatings 11 sticks on PMMA plate 12 equably, not only structure comparison is stable for the antistatic backing 1 of this technology, also a saving raw material, economic and practical is strong, effectively can prevent the pollution caused because electric attraction effect causes film top layer attract dust and solid granule, simultaneously, also be provided with porous layer 3, porous layer 3 not only has the effect that sound insulation is eliminated the noise, permeation functions can also be played, this film is environmental protection, the film that practicality is stronger, applied widely, be worthy to be popularized.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, being all casehistory, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
