Description
Technical field
The utility model relates to printing film coating technique field, and particularly the important materials pre-coating film of overlay film is a kind of pre-coating film that adopts the extrusion composite technology technology to make.
Background technology
The printed matter overlay film is the important means of post-press finishing, the final personal value of its decision print product.The coating technique of printed matter is meant with plastic sheeting and covers above the paper printing matter, the middle adhesive that uses, after the heating pressurized treatments, two kinds of materials of different nature of plastic sheeting and paper are bonded together, form paper/the mould incrustation process technology of unification.It plays protection and decorative effect to printed matter, is widely used in the packages printing field, on the Surface Machining as Front cover of book and periodical, propaganda picture album, map, advertising specialty bag, senior packing box etc.Overlay film can divide promptly films and two kinds of pre-coating films.
Promptly be coated with membrane technology and be that the international sixties rise to coating technique behind the seal of printed matter, package.But this technology is directly used in the overlay film process and is contained benzene solvent, thereby has brought the three big drawbacks that can't overcome owing to self technology:
(1) environmental issue: because the volatilization of noxious material benzene and overflowing has caused air pollution and brought very big harm for the producer and user's health; Simultaneously, the harmful substance that residues in the overlay film has harmful effect to consumer's health.
(2) quality problems: owing to still have volatile substance benzene constantly to overflow after the overlay film processing, very easily between film and paper, form bubble, make printing product surface be vaporific, influence fineness, definition and the colour vividness of printing; Sometimes because of bonding strength is not enough, even cause cracking, fold and demoulding.In addition, the production equipment automaticity of promptly filming is low, has reduced the overlay film yield rate.
(3) safety problem: owing to contain volatile organic solvent benzene in the solution, form flammable, explosive atmosphere easily around the liquid bath, and the plastic basis material that the uses generation static that rub causes disaster hidden-trouble in operation process.Such accident number had taken place, and little then the shutdown stops production, and greatly then machine burns, and factory building caves in, casualties.
The pre-coating film film coating technique is the green technology of sustainable development.The pre-coating film film coating technique also can be referred to as environmental friendliness technology or clean technologies, has realized the protection environment, protects the health, has kept the safety in production.In pre-coating film production and the use, the volatilization that toxic gas does not take place is polluted, and therefore, effectively improves working environment, eliminates the disaster hidden-trouble that production site and product are stored; Use the pre-coating film product,, can be widely used on the packing of books and periodicals (especially student textbook), food, tobacco and wine, medicine etc. the consumer not being constituted potential threat owing to wherein do not have the hazard residue material; The process procedures such as allotment, coating and oven dry of binder have been saved simultaneously, the whole film covering process can in seconds be finished, and can not produce pollution to environment, does not have disaster hidden-trouble, do not need to clean automatic double surface gluer etc. yet, can realize high speed, efficient, high-quality overlay film; Pre-coating film has promoted the color saturation of printed matter and definition, has obviously increased its artistic effect; and printed matter played a protective role; make it water-fast, moisture resistance, fast light, prevent pollution, anti-chemical corrosion; increase the service life; improve durability, collection and the ornamental value of printed matter greatly, promoted the commercial competitiveness and the added value of product.
Pre-coating film structure difference, adopt the base material difference different with hot melt adhesive layer, the performance of pre-coating film product has very big-difference, and the effect of product also has very big difference behind the overlay film, as aspects such as color saturation, brightness, tensile strength, wide degree, flatness.
The utility model content
The purpose of this utility model is: a kind of biaxial tension nylon (BOPA) pre-coating film is provided, improve the exquisite degree of printing, constant product quality, not only environmental protection, safety, convenience, energy-conservation, efficient, and can satisfy some clients to overlay film after product requirement have good barrier, puncture resistance and impact resistance, high brightness, the demand of heat sealability and hygroscopicity, impressionability preferably.Owing to not with an organic solvent, do not overcome the deficiency of promptly filming and existing.
The technical solution adopted in the utility model is: biaxial tension nylon (BOPA) pre-coating film, comprise base material, intermediate layer and hot melt adhesive layer, it is characterized in that: on the surface of base material intermediate layer and hot melt adhesive layer are arranged successively, the width of base material, intermediate layer and hot melt adhesive layer is identical.Base material is BON biaxially oriented nylon film (BOPA), and the intermediate layer is polymine (PEI), and hot melt adhesive layer is the EVA PUR.Intermediate layer and hot melt adhesive layer evenly apply successively, are compounded on the surface of base material.The thickness of base material is between the 12-20 micron, and (coated weight is 0.009-0.011g/m to the thickness in intermediate layer at the 0.01-0.03 micron
2) between, the thickness of hot melt adhesive layer is between the 15-40 micron.
Technical scheme is preferably: the thickness of base material is between the 12-15 micron, and (coated weight is 0.009-0.01g/m to the thickness in intermediate layer at the 0.01-0.02 micron
2) between, the thickness of hot melt adhesive layer is between the 15-30 micron.
The composite production line that utilizes extruder and equipment complex to form is coated in the intermediate layer on the surface of base material, at last hot melt adhesive layer is compounded on the intermediate layer production biaxial tension nylon (BOPA) pre-coating film.After the thickness of base material and EVA hot melt adhesive layer carries out suitable combination, can obtain different products.Above-mentioned extruder and equipment complex and combination process are well known to those skilled in the art.
The EVA PUR is a kind of solid meltability polymer that does not need solvent, moisture-free 100%; Be solid at normal temperatures, heating and melting becomes and can flow to uniform temperature, and the liquid of certain viscosity is arranged.EVA PUR after the fusion is light yellow or colourless.The EVA PUR is become to be grouped into by basic resin, tackifier, viscosity modifier and antioxidant etc.At present, apply level EVA PUR product and mainly rely on import, domestic no appropriate level production.
Polymine (PEI) molecular formula is: [CH
