Abstract
The utility model discloses a non-gel compound film comprising a matrix layer and a function layer co-extruded and arranged on the matrix layer, and the function layer can be compounded with paper wood, pre-printing paper wood, metal slice, pre-printing metal slice or film comprises an original layer. The matrix layer is a biaxial oriented polypropylene film, a biaxial oriented polyethylene glycol terephthalate film, a biaxial oriented polystyrene film, a biaxial oriented daiamid film or a flow casting polypropylene film. The film of the utility model can be compounded with various packaging material comprising the film function layer without glue, and when compounding, poisonous gas cannot be produced. The utility model with the advantages of simple structure and high intensity of composite has great application value in the packaging and compounding industry.
Description
Technical field
The utility model relates to a kind ofly can directly not have the compound film of glue.
Background technology
At present, industrially be applied to paper or mould compound way mainly contain following several: first glue method (dry method is compound and wet method is compound), yet thereby the toxic solvent serious environment pollution that this method can be more to airborne release; 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, though this method can be without solvent, but operation is more, increases cost.In addition, said method gained joint product adhesive linkage peel strength time dependence is more obvious.Therefore, for overcoming in the prior art paper or moulding compound shortcoming, the applicant's number of filing an application once is: 200620154717.2 paper or the patent application of moulding glue-free composite bidirectional stretching polypropylene film.Yet, this technical scheme only contains one of packaging material type: bidirectional stretching polypropylene film, in the no glue complex technique field of film, necessaryly develop a kind of no glue laminated film that can be combined into various paper materials with matching materials, mould multiple packaging material such as moulding material or plastic-metal material.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of to realize that packaging material with various couplings do not have glue compound, and compound tense can not produce toxic gas, simple in structure, no glue laminated film that the product combined strength bination is high.
Goal of the invention of the present utility model is achieved in that a kind of no glue laminated film, it is characterized in that: it comprises that base layer and coextru-lamination are on base layer and can be directly and paper wood, preprint paper wood, sheet metal, preprint sheet metal or contain the compound functional layer of film of this layer.
Described base layer is the base layer of bidirectional stretching polypropylene film.
Described base layer is the base layer of biaxial tension pet film.
Described base layer is the base layer of biaxially oriented polystyrene film.
Described base layer is the base layer of two-way stretching polyamide film.
Described base layer is the base layer of cast polypropylene film.
Adopt the no glue laminated film of said structure, its beneficial effect is:
No glue laminated film described in the utility model comprises base layer and extrudes the functional layer of coextru-lamination on base layer, and at the Different Package material, base layer can be the base layer of bidirectional stretching polypropylene film, pet film, polystyrene film or various films such as polyamide film and cast polypropylene film, membrane structure is simple, the no glue of realized paper, moulding film or plastic sheeting-metal material is compound, and, compound tense can not produce toxic gas, product combined strength bination height.
Description of drawings
The structural representation that accompanying drawing 1 is implemented for the utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings shown in 1, no glue laminated film of the present utility model, it comprises that base layer 1 and coextru-lamination are on base layer 1 and can be directly and paper wood, preprint paper wood, sheet metal, preprint sheet metal or contain the compound functional layer 2 of film of this layer.When this thin film fabrication, functional layer 2 is passed through the corresponding apparatus coextru-lamination on the surface of base layer 1.Functional layer and base layer 1 are the coextru-lamination structure, and are directly obtained by flat embrane method of biaxial tension or The tape casting, have avoided the trouble operation of online or off-line painting process.Wherein, base layer 1 specifically can be the base layer of bidirectional stretching polypropylene film, or for the base layer of biaxial tension pet film, or be the base layer of biaxially oriented polystyrene film, or be the base layer of two-way stretching polyamide film, or be the base layer 1 of cast polypropylene film; And functional layer 2 can be the modified by maleic acid anhydride graft thing of ethylene-butene copolymer, ethylene-octene copolymer, ethene-butylene-octene copolymer, ethylene-butene copolymer, the modified by maleic acid anhydride graft thing of ethylene-octene copolymer, the modified by maleic acid anhydride graft thing of ethene-butylene-octene copolymer or their blend, or any composition of above copolymer, modifier, blend respectively with the blend again of hydrogenated petroleum resin.In addition, for strengthening the combination property of base layer 1, this base layer 1 also can contain one or more in antistatic additive, slipping agent, intensity strengthening agent, the antiblocking agent.Film described in the utility model all can realize that no glue is compound with the various packaging material that contain this film functional layer 2, and compound tense can not produce toxic gas, simple in structure, product combined strength bination height, has very big using value for packing compound industry.
