Abstract
The invention discloses a polyolefin high barrier film processing technology. The polyolefin high barrier film employs a three-layer co-extrusion casting process, and comprises two surface layers and one middle layer; the middle layer by mass fraction comprises 7-8.5 parts of polyolefine and 1.5-3 parts of nano inorganic clay; the middle layer material is heated and extruded at 230-260 DEG C for multilayer lamination, and attached with the surface layer; the surface layer comprises, by weight, 9 parts of polyolefin and 1 part of active organic silicon; the surface layer material is heated and extruded at 230-260 DEG C, and attached with the middle layer; and the thickness ratio of the middle layer to the surface layer is 4:3. Polyolefin and nano inorganic clay are heated, extruded and mixed to form a continuous multilayer inorganic nano barrier layer, in order to enhance the barrier properties of polyolefin film, active organic silicon is added on the surface layer to change the viscosity of the surface layer, in order to reduce the surface viscosity of the polyolefin film and facilitate the coil stripping of a polyolefin film roll.
Description
Technical field
The present invention relates to plastic package material technical field, specifically a kind of polyolefin high-isolation film processing technology.
Background technology
In existing packaging material, the barrier of polyolefine material is poor, oxygen, steam, fragrance and organic molecule can have influence on performance and the life-span of packing content thing easily through polyolefin film, in order to increase polyolefinic barrier property, existing polyolefin film passes through MULTILAYER COMPOSITE, surface evaporation, surface applies and the technique such as multi-layer co-extruded increases the barrier of polyolefin film, adopt MULTILAYER COMPOSITE, surface evaporation, the method that surface applies not only will change production equipment and production stage complicated production cost uprises, although adopt multi-layer co-extruded method method simple, but barrier property is still good not.
General polyolefin film is because its surperficial viscosity can make adhesion between polyolefin film, therefore in general polyolefm film layer, all can prevent by coating active organosilicon the adhesion of polyolefin film, prevent polyolefin film uncoiling difficulty, and can the quality of packaging bag content be impacted making after packaging bag in the words that film surface scribbles active organosilicon.
Summary of the invention
The present invention is directed to prior art deficiency, a kind of polyolefin high-isolation film processing technology is provided, can produce and there is good barrier by this processing method, facilitate polyolefin film uncoiling, and low production cost.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of polyolefin high-isolation film processing technology, described polyolefin high-isolation film adopts three-layer co-extruded casting technique processing, described polyolefin high-isolation film comprises two superficial layers and intermediate layer, described intermediate layer comprises 7-8.5 part polyolefin by mass fraction, 1.5-3 part nano inorganic clay, intermediate layer material adds and hot-extrudablely fits with superficial layer after carrying out multilayer build-up at 230 DEG C-260 DEG C, described superficial layer comprises 9 parts of polyolefin by mass fraction, 1 part of active organosilicon, surface layer material adds hot-extrudable and intermediate layer laminating at 230 DEG C-260 DEG C, the Thickness Ratio of intermediate layer and superficial layer is 4:3.In heating by polyolefin and nano inorganic clay, the situation of extruding, mixing, form the inorganic nano barrier layer of continuous multilayer, increase the barrier property of polyolefin film with this, on superficial layer, add active organosilicon to change the viscosity of superficial layer, the viscosity on polyolefin film surface is reduced, thereby make polyolefin film volume film coil stripping more convenient, and the active organosilicon of being dissolved into polyolefin film inside is being made the quality that can not have influence on packing content thing after packaging bag.
The present invention compared with prior art, there is following beneficial effect: the inorganic nano barrier layer that forms continuous multilayer in the heating of the present invention by polyolefin and nano inorganic clay, the situation of extruding, mixing, increase the barrier property of polyolefin film with this, on superficial layer, add active organosilicon to change the viscosity of superficial layer, the viscosity on polyolefin film surface is reduced, thereby make polyolefin film volume film coil stripping more convenient.
