Abstract
The invention relates to a polyethylene film for hot-pressing compositing, particularly to a polyethylene film which can be composited with paper or ink-containing pre-printing paper directly by hot pressing. The polyethylene film at least comprises a substrate layer and a hot-pressing compositing layer, wherein the substrate layer is made of biaxially oriented film class polyethylene or ethane-1-ethane copolymer; the hot-pressing compositing layer can be directly composited with paper or ink-containing pre-printing paper by hot pressing, and made of ethane-Alpha olefin copolymer in which the weight percentage of Alpha olefin is 15-25 % or MAH (maleic anhydride) grafted modifier of the ethane-Alpha olefin copolymer or a mixture of the two above, wherein the hot-pressing compositing layer comprises the following compositions:(a) an ethylene-1-butylene copolymer; or (b) an ethylene-1-octylene copolymer; or (c) the MAH grafted modifier of the ethylene-1-butylene copolymer; or (d) the MAH grafted modifier of the ethylene-1-octylene copolymer; or e) any combination of (a), (b), (c) and (d); or (f) the mixture of (e) and hydrogenated petroleum resin.
Description
Technical field
The present invention relates to the compound polyethylene film of using of a kind of hot pressing, especially a kind ofly can directly realize the polyethylene film that hot pressing is compound with paper or the preprinted paper that contains printing ink.
Background technology
The polyethylene film production technology comprises blown film method peace embrane method, is main with the blown film method in the prior art.In flat embrane method, be divided into progressively biaxial tension and synchronous bidirectional again and stretch two kinds, wherein with biaxial tension progressively and to carry out twice stretching (cross directional stretch after promptly vertical earlier) be main.
At present, be applied to the paper composite methods in the industry and mainly contain following several kinds: first glue method (dry method is compound compound with wet method), however adopt this method can give off more toxic solvent or fugitive constituent, thus environmental pollution caused; It two is solvent-free composite algorithms, and the initial bonding strength of this method gained joint product is extremely low; It three is precoating methods, as Chinese patent number for the compound precoating of paper of ZL03278870.3 with the technology that plastic sheeting disclosed, though this method can belong to the secondary operations technology of biaxially oriented film without solvent, its cost is higher.In addition, said method, the peel strength of particularly solvent-free composite algorithm gained joint product adhesive linkage reduces in time and gradually.
For overcoming the above-mentioned shortcoming of existing paper complex technique; Disclose a kind of paper plastic glue-free composite bidirectional stretching polypropylene film and preparation method thereof among the Chinese patent ZL200710006100.5, the said Biaxially oriented polypropylene of this patent does not have the glue composite membrane can be directly and paper wood or preprint paper wood to carry out hot pressing compound.
Disclose a kind of multi-layered high-density polyethylene film of height biaxial orientation among the Chinese patent ZL 98811126.8, this film has adopted the propylene copolymer top layer, but can not be directly and paper wood or preprint paper wood to carry out hot pressing compound.The paper film-covered member resistance to tearing that this paper film coating technique is obtained is relatively poor, and the tearing strength of its bidirectional stretching polypropylene film is almost nil, when be used to account for 157 bigger grams of usage ratio/square metre or when following art paper, offset paper, its problem is more outstanding.
Summary of the invention
The compound polyethylene film of using of a kind of hot pressing provided by the invention adopts this film, has realized on the one hand with paper wood or to preprint the direct hot pressing of paper wood compound, the solvent contamination of having save coating technique, having removed traditional glue method; The aspect adopts this film more tear-resistant than the paper film-covered member of bidirectional stretching polypropylene film in addition.
Concrete technical scheme of the present invention is following.
The compound polyethylene film of using of a kind of hot pressing, this film comprise a base layer and a hot pressing composite bed at least.Base layer is biaxially oriented film level polyethylene or ethene-1-hexene copolymer; The hot pressing composite bed can realize that directly hot pressing is compound with paper or the preprinted paper that contains printing ink; Its material for the alhpa olefin weight content account for 15～25% ethylene-alpha-olefin copolymer or its modified by maleic acid anhydride graft thing or both blends or aforementioned copolymer, modifier or blend respectively with the blend again of hydrogenated petroleum resin, comprising:
A). ethene-butene-1 copolymer
Or b). ethene-1-octene copolymer
Or C). the modified by maleic acid anhydride graft thing of ethene-butene-1 copolymer
Or d). the modified by maleic acid anhydride graft thing of ethene-1-octene copolymer
Or e) any mixture d c b .a))))
Or f) .e) with the blend again of hydrogenated petroleum resin.
Be quality and the performance of guaranteeing product; The polyethylene raw material that is adopted in a preferred embodiment is the biaxially oriented film level polyethylene that molecular weight distribution has double-peak feature, and the ethene that is adopted-1-hexene copolymer is biaxially oriented film level ethene-1-hexene copolymer that molecular weight distribution has double-peak feature.
