Abstract
The utility model provides a printing bag film, and relates to a plastic membrane structure; the printing bag film consists of a central layer and two surface layers which have the total thickness of 20mu m; and the printing bag film is characterized in that the two surface layers respectively have the thickness of 1.1-1.2mu m. The printing bag film has the advantages that experiments prove that after being thickened, silica does not excessively protrude out of the surface layer, and dust pollution is not caused in the printing process.
Description
Technical field:
The utility model relates to the plastic film structure, particularly a kind of printing and bag making film.
Background technology:
Plastic printing bag film is generally the trilamellar membrane structure, is made up of applying top layer, central core both sides.The central core material is a HOPP, and a kind of material in top layer also is a HOPP, and this skin-material can not use hot sealing process.The another kind of material in top layer is a COPP, and this material can use hot sealing process.Bag film standard thickness is 20 μ m, and each producer of prior art all is that central core is that 18 μ m, two top layers are 1 μ m.Because the end product of bag film on production line is into web-like, in order to prevent to stick together behind the coiling, therefore in skin-material, add 2% antiblocking agent masterbatch, and contain 5% random inorganic silica in this masterbatch, this silica particle diameter is 2-5 μ m.The silica particle diameter is greater than skin depth, but in the mould of injection moulding extrusion device, because two side templates are smooth flat, so silica gabarit one side is fitted on the side form wooden partition, and opposite side is extruded and mixes in the central core.And diaphragm will pass through multiple tracks cooling, heating, longitudinal stretching, cross directional stretch after extruding, thereby finished film sees that from macroscopic view outer surface is smooth smooth, but sees from microcosmic, and the partly phenomenon on outstanding top layer of silica is still arranged.
When diaphragm printed, the part silica of projection can fracture under the effect of printing guide roll mill pressure, grinding, produces powder and cause on the diaphragm; And these powder produce pollution; Make printed patterns produce leak source, pit, influence printing quality, equipment often will be shut down the cleaning maintenance.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and a kind of printing and bag making film is provided.
The scheme of the utility model is: be made up of central core, two top layers, gross thickness is 20 μ m, it is characterized in that: two skin depths are respectively 1.1-1.2 μ m.
The advantage of the utility model is: through verification experimental verification, after the top layer thickening, silica can excessive protruding top layer, in printing process, can not produce powder and pollute.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
The utility model is made up of central core 2, two top layers 1, and gross thickness is 20 μ m, it is characterized in that: two top layers, 1 thickness is respectively 1.1-1.2 μ m.
Though 1 thickening in top layer 0.1-0.2 μ m proves from test effect, can not produce powder and pollute.
Claims (1)
1. a printing and bag making film is made up of central core (2), two top layers (1), and gross thickness is 20 μ m, it is characterized in that: two top layers (1) thickness is respectively 1.1-1.2 μ m.
