Abstract
The invention relates to a composite film which is prepared by carrying out plastic-plastic thermal compounding on a plurality of layers of thin films. The composite structure is composed of an upper biaxially oriented polypropylene film, a middle printing ink film and a lower biaxially oriented polypropylene film, wherein the upper biaxially oriented polypropylene film comprises at least two layers, namely, an upper polypropylene substrate layer and a heat-seal layer arranged at the interior of the upper polypropylene substrate layer, and the heat-seal layer is prepared from a biopolymer or terpolymer or mixture of ethylene, propylene and butylene at an initial heat-seal temperature of less than or equal to 95 DEG C; and the lower biaxially oriented polypropylene film comprises at least two layers, namely, a lower polypropylene substrate layer and a function layer directly contacted with printing ink, and the function layer comprises the following compositions: 1) an ethylene-butylene copolymer; or 2) an ethylene-octylene copolymer; or 3) an MAH (maleic anhydride) grafted modifier of the ethylene-butylene copolymer; or 4) an MAH (maleic anhydride) grafted modifier of the ethylene-octylene copolymer; or 5) any mixture of the compositions 1), 2), 3) and 4); or 6) the mixture of the composition 5) and hydrogenated petroleum resin.
Description
Technical field
The present invention relates to a kind of moulding-plastic composite structure, specifically, relate to a kind of by plural layers by moulding-mould the laminated film that makes of the compound mode of heat.
Background technology
By moulding-mould the flexible packing material that film that compound mode produces is used as article more, this laminated film carries out multiple film by the mode of having complementary advantages compound, thereby satisfies the demand of packing of product aspect between the plastic sheeting.
The complex technique of moulding-mould of existing film is mainly undertaken plural layers compound by adhesive.Generally be by online coating method, earlier on a kind of polarity treatment surface of film, be coated with glue, through to carry out heat under uniform temperature and pressure condition compound with another film or the film that is printed on ink lay after the drying tunnel drying.The laminated film that this mode obtains often contains a certain amount of residual solvent, and packed article or consumer are had a negative impact.
Summary of the invention
The present invention relates to a kind of novel moulding-plastic composite structure, the superficial layer of the thin film in this structure---bidirectional stretching polypropylene film can directly combine with ink lay, and by printing ink and other thin film---heat sealable bidirectional stretching polypropylene film, directly hot pressing is compound and need not to use adhesive under the certain temperature and pressure condition.
Of the present invention moulding-plastic composite structure has thoroughly been removed and has been used in the conventional composite membrane structure or negative effect that residual solvent causes, has simplified combination process.It not only has energy-conservation effect, and is particularly conducive to the health and the environmental protection of flexible packaging food.
Moulding among the present invention-plastic composite structure is to realize by the compound mode of hot pressing.This composite construction is made up of a upper strata bidirectional stretching polypropylene film, middle ink lay and lower floor's bidirectional stretching polypropylene film, its upper strata bidirectional stretching polypropylene film is at least double-layer structure, it comprises base layer on the polypropylene and is positioned at the heat sealable layer of its inboard, and this hot sealing layer is that initial heat-sealing temperature is less than or equal to 95 ℃ ethene, propylene, butylene two yuan or terpolymer and composition thereof.Lower floor's bidirectional stretching polypropylene film is at least double-layer structure, and it comprises polypropylene lower substrate layer and the functional layer that directly contacts with printing ink, and the composition of this functional layer is:
1). ethylene-butene copolymer
Or 2). ethylene-octene copolymer
