Abstract
The utility model discloses an environment-friendly adhesive modified polyester-aluminum-polypropylene composite film for medicine/food packaging, which comprises a polyester film layer, an aluminum foil layer and a casting polypropylene film layer, wherein the polyester film layer is an external surface layer; the aluminum foil layer is arranged between the polyester film layer and the casting polypropylene film layer; and an environment-friendly adhesive layer is respectively arranged between the polyester film layer and the aluminum foil layer, and between the aluminum foil layer and the casting polypropylene film layer. The polyester-aluminum-polypropylene composite film for medicine/food packaging, which is produced by composite bonding and modification of the alcohol-water environment-friendly composite adhesive, can enable the production of the polyester-aluminum-polypropylene composite film product for medicine/food packaging not to pollute the environment any more, and greatly enhances the sanitary safety of the composite sheet product; and the ultraviolet absorption quality index of the composite sheet product is lowered many times, thereby greatly enhancing the quality maintenance of the composite film for the packaged medicine or food.
Description
Technical field
The utility model relates to a kind of drug and food composite packing film, particularly relates to a kind of environmental protection glue modified poly ester-aluminium-polypropylene drug and food composite packing film.
Background technology
Between existing used for packing foods composite film and the layer with adhesive bonding be composited moisture, oxygen and smell are had the composite soft packaging material of good comprehensive barrier, mainly as the printing soft packaging bag of Chinese formulated products and food.Because the production of this compound soft packing material need be adopted the adhesive of cementability more anti-boiling (for sterilization), and the adhesive that can reach this requirement in the past has only toluene or the ethyl acetate solvent borne polyurethane hot setting adhesive of non-Environmental Safety, when producing the drug and food composite packing film, just used the non-Environmental Safety adhesive of this class like this, cause poisonous toluene or the pollution of ethyl acetate solvent gas discharging and inflammable and explosive potential safety hazard to production environment, more seriously make higher the exceeding standard of the toxic Determination of Residual Organic Solvents of composite membrane product easily, its sanitary toxicology is affected.
The utility model content
The purpose of this utility model is that environmental protection glue modified poly ester-aluminium-polypropylene drug and food composite packing film that a kind of production cost is low, moisture, oxygen and smell had good comprehensive barrier is provided in order to address the above problem.
The utility model is achieved through the following technical solutions:
A kind of environmental protection glue modified poly ester-aluminium-polypropylene drug and food composite packing film, comprise laminated polyester film, aluminium foil layer and cast polypropylene film layer, described laminated polyester film is outer surface layer, described aluminium foil layer places between described laminated polyester film and the described cast polypropylene film layer, between described laminated polyester film and the described aluminium foil layer, be provided with the environment-friendly adhesive layer between described aluminium foil layer and the described cast polypropylene film layer.
Further, described environment-friendly adhesive layer is made up of aqueous polyurethane tackifier layer grafting, copolymerization and modification spirit solvent type polyacrylate adhesive layer.The environment-friendly adhesive layer can not only make laminated polyester film, aluminium foil layer and cast polypropylene film layer be bonded together securely, and can not produce toxic and harmful in the composite sheet process, so do not pollute the environment.
As preferably, the thickness of described laminated polyester film is 0.05-0.1mm.
As preferably, the thickness of described cast polypropylene film layer is 0.1-0.2mm.
As preferably, the thickness of described environment-friendly adhesive layer is 0.02-0.05mm.
The beneficial effects of the utility model are:
Adopt the modification of alcohol-water type environmental protection composite adhesive compound sticking to produce polyester-aluminium-polypropylene drug and food composite packing film, the production that not only makes polyester-aluminium-polypropylene drug and food composite packing film product is contaminated environment no longer, and the wholesomeness of composite sheet product is improved greatly; Also make simultaneously the ultraviolet absorptivity quality index of composite sheet product reduce several times, strengthened the guaranteeing the quality property of this composite membrane to the packaging medicine greatly.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments:
As depicted in figs. 1 and 2, the utility model environmental protection glue modified poly ester-aluminium-polypropylene drug and food composite packing film 1, comprise laminated polyester film 2, aluminium foil layer 3 and cast polypropylene film layer 4, described laminated polyester film 2 is outer surface layer, described aluminium foil layer 3 places between described laminated polyester film 2 and the described cast polypropylene film layer 4, between described laminated polyester film 2 and the described aluminium foil layer 3, be provided with environment-friendly adhesive layer 5 between described aluminium foil layer 2 and the described cast polypropylene film layer 4.In the present embodiment, described laminated polyester film 2 is biaxially oriented polyester film.Biaxially oriented polyester film has characteristics such as intensity height, good rigidly, transparent, glossiness height; Do not have smell, tasteless, colourless, nontoxic, outstanding obdurability; Its hot strength is PC film, nylon membrane 3 times, and impact strength is 3-5 times of BOPP film, and excellent abrasion resistance, folding resistance, anti-pin hole and tear resistance etc. are arranged; Heat-shrinkable is minimum.
Described environment-friendly adhesive layer 5 is made up of aqueous polyurethane tackifier grafting, copolymerization and modification spirit solvent type polyacrylate adhesive.Environment-friendly adhesive layer 5 can not only make laminated polyester film 2, aluminium foil layer 3 and cast polypropylene film layer 4 be bonded together securely, and can not produce toxic and harmful in the composite sheet process, so do not pollute the environment.
The thickness of described laminated polyester film 2 is 0.05-0.1mm.The thickness of described cast polypropylene film layer 4 is 0.1-0.2mm.The thickness of described environment-friendly adhesive layer 5 is 0.02-0.05mm.In the present embodiment, the thickness of described laminated polyester film 2 is for being 0.08mm, and the thickness of described cast polypropylene film layer 4 is 0.15mm, and the thickness of described environment-friendly adhesive layer 5 is 0.03mm.
