Abstract
The utility model relates to an MCP three-layer co-extrusion non-stretched polypropylene film which comprises a propene polymer. The utility model is characterized in that the film is successively composed of a heat sealing layer, a core layer and a corona processing layer, wherein, the heat sealing layer is a copolymer of propene and ethene or butylene, and added by anti-adhesion agent and slip agent; the core layer is a single crystal polymer of the propene; the corona processing layer is a copolymer of the propene and the ethene or the butylene, which is processed by high-pressure electric discharge. The utility model has the advantages of low heat sealing temperature for an aluminizing base film, large friction coefficient for the film to enhance the production efficiency of an automatic packing production line, large tension on the film surface and good maintaining property to delay attenuation speed, and favorable color printing and compound producing effects.
Description
Technical field
The utility model relates to a kind of polypropylene film, the three-layer co-extruded un-stretched polypropylene film of particularly a kind of MCP.
Background technology
The existing at present composite membrane internal layer (being the aluminium plating basement membrane that aluminizer adopts) that is applied to the packings of product such as food, medicine, adopt the individual layer co-extrusion, be that single raw material had both been done hot sealing layer, do corona processing layer again, the aluminium plating basement membrane heat-sealing temperature height that the method is produced, can't satisfy High-Speed Automatic packaging production line, and the sided corona treatment effect is relatively poor, influence aluminize between back aluminium lamination and the aluminium plating basement membrane in conjunction with fastness, additive is less in the raw material in addition, influence the coefficient of friction of film, influence the speed of production of automatic packaging production line.
Summary of the invention
The purpose of this utility model is the individual layer coextruded structure that solves composite membrane internal layer (being the aluminium plating basement membrane that the aluminizer adopts) employing that is used for the packings of product such as food, medicine in the prior art, aluminium plating basement membrane heat-sealing temperature height, the sided corona treatment effect is relatively poor, the less problem that causes the coefficient of friction of film lower, can't satisfy High-Speed Automatic packaging production line of additive in the raw material.The three-layer co-extruded un-stretched polypropylene film of the utility model design MCP, comprise acrylic polymers, it is characterized in that: film is made of hot sealing layer, sandwich layer and corona processing layer successively, wherein hot sealing layer is the copolymer of propylene and ethene or butylene, also add antiblocking agent and slipping agent, sandwich layer is the propylene monomer polymer, and corona processing layer is through the propylene of electrion processing and the copolymer of ethene or butylene.The utility model has the advantages that the aluminium plating basement membrane heat-sealing temperature is low, thus the big production efficiency that improves automatic packaging production line of the coefficient of friction of film, film surface has than hightension and good maintenance, delays the rate of decay, and color printing, compound production effect are good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, accompanying drawing is a structural representation of the present utility model,
Comprise acrylic polymers among the specific embodiment figure, it is characterized in that: film is successively by hot sealing layer 1, sandwich layer 2 and corona processing layer 3 constitute, wherein hot sealing layer 1 is the copolymer of propylene and ethene or butylene, thereby reduced the heat-sealing temperature of film significantly, can satisfy High-Speed Automatic packaging production line, also added more additive such as antiblocking agent and slipping agent in the hot sealing layer 1, improved the coefficient of friction of film, improved the production efficiency of automatic packaging production line greatly, sandwich layer 2 is the propylene monomer polymer, mainly play the supporting role of skeleton, corona processing layer 3 is the copolymer of propylene and ethene or butylene, except that a spot of antiblocking agent, do not contain other additives, has good corona effects, i.e. effect by electrion, form the concavo-convex phenomenon of microcosmic on film corona processing layer 3 surfaces, make this layer by the initial nonpolar effect that reaches polarity after treatment, increase the surface tension of film, and has good maintenance, delay the rate of decay, guarantee follow-up color printing, the effect of compound production.
