Abstract
Delustring CPP film is comprised of tri-layers of A layer delustring PP, B layer homopolymerization PP and C layer delustring PP, and the formula bed thickness of A layer delustring PP, B layer homopolymerization PP and C layer delustring PP is than being 1:3:1; A layer delustring PP is comprised of 80%PGR2446 and 20% binary the third F800E; B layer homopolymerization PP is comprised of 95%T30S and 5% auxiliary agent; C layer delustring PP is comprised of 80%PGR2446 and 20% ternary third 7632; The utility model matt film outward appearance is dumb light effect, has obscuration aesthetic sense, aobvious high-grade; Surface frosted feel, and quality is soft, and texture is splendid; Compare with delustring OPP on the market, delustring CPP has two-sided splendid heat sealability, without compound, can directly seal into bag; Without compound, pliability is better, and without gluing, both cost-saving, reduced again solvent contamination; The utility model process automation degree is strong, and efficiency is high, profitable.
Description
Technical field
The invention belongs to matt film technical field, what be specifically related to is a kind of delustring CPP film.
Background technology
Along with people's living standard progressively improves, paper for daily use not only in amount demand increasing, and also improve constantly in matter, paper handkerchief packing is on the market almost transparent entirely at present, fraction is milky white, there is no difference, there is no class,
also there is fraction to beadopt BOPP matt film, BOPP matt film adds the poor material of several compatibilities by the one side at BOPP film, when stretched, and the countless micropores of incompatible generation of interfaces, these micropores make to be irradiated to this surperficial light and produce diffusion or scattering many times, thereby reach the object of delustring.
Because BOPP matt film is the incompatible generation of interfaces pore between macromolecular compound and silica or calcium carbonate fine powder and reach the object of delustring while stretching through high multiple, therefore BOPP matt film has also been caused to a lot of infringements, as the scratch of delustring layer, sticky wound, melt body the break abatjour that produces, silver point etc., cause BOPP film impact strength poor, resistance to tearing is poor, has limited it in the extensive utilization of many packaging fields.
Summary of the invention
The object of this invention is to provide a kind of flexible, delustring CPP film resistance toly pierce through, tear-resistant performance being good and preparation method thereof.
The present invention is achieved by the following technical solutions: delustring CPP film, by tri-layers of A layer delustring PP, B layer homopolymerization PP and C layer delustring PP, formed, and the formula bed thickness of A layer delustring PP, B layer homopolymerization PP and C layer delustring PP is than being 1:3:1.
Described A layer delustring PP is comprised of 80%PGR2446 and 20% binary the third F800E.
Described B layer homopolymerization PP is comprised of 95%T30S and 5% auxiliary agent.
Described C layer delustring PP is comprised of 80%PGR2446 and 20% ternary third 7632.
Beneficial effect of the present invention embodies and is: compared with prior art, matt film outward appearance of the present invention is dumb light effect, has obscuration aesthetic sense, aobvious high-grade; Surface frosted feel, and quality is soft, and texture is splendid; Compare with delustring OPP on the market, delustring CPP has two-sided splendid heat sealability, without compound, can directly seal into bag; Without compound, pliability is better, and without gluing, both cost-saving, reduced again solvent contamination; Process automation degree of the present invention is strong, and efficiency is high, profitable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is flow diagram of the present invention.
The specific embodiment
As shown in Figure 1, delustring CPP film, consist of, and the formula bed thickness of A layer delustring PP 1, B layer homopolymerization PP 2 and C layer delustring PP 3 is than being 1:3:1 3 three layers of A layer delustring PP 1, B layer homopolymerization PP 2 and C layer delustring PP.
Described A layer delustring PP 1 is comprised of 80%PGR2446 and 20% binary the third F800E.
Described B layer homopolymerization PP 2 is comprised of 95%T30S and 5% auxiliary agent.
Described C layer delustring PP 3 is comprised of 80%PGR2446 and 20% ternary third 7632.
As shown in Figure 2, the preparation method of delustring CPP film: carry out automatic blending in the feed proportioning system of extruder, raw material through preparing compares and passes through filter screen and extrude by certain bed thickness in extruder, and its extruder extruded material merges into three layers and goes out through die head lip curtain coating at die head conductance face place; The high temperature melt going out from die head lip curtain coating is fallen cold roller traction and is cast film; And at film surface, carry out sided corona treatment, its corona value is not less than 44 dyne, casts film laggard gap in the ranks rolling and cuts; Film appearance surface has not allowed cut, greasy dirt, impurity, wrinkle extremely, abnormal precipitate, obviously water wave, impression and mosquito.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
