Abstract
The utility model discloses an environment-friendly rubber modified polyester-aluminum-polyethylene composite membrane for medicine food packaging, which comprises a surface layer, a middle layer and an inner layer, wherein the surface layer is a biaxial stretching polyester layer, the middle layer is an aluminum foil layer, and the inner layer is a polyethylene layer. Alcohol-waterborne polyurethane modified polyacrylate adhesive layers are arranged between the biaxial stretching polyester layer and the aluminum foil layer and between the aluminum foil layer and the polyethylene layer. Alcohol-waterborne polyurethane modified polyacrylate adhesives with high boiling resistance performance are adopted to replace prior non-environment-friendly and insecure toluene or acetic ether solvent type polyurethane thermosetting adhesives. A polyethylene terephthalate (PET)/ aluminum (AL)/ polyethylene (PE) composite membrane for medicine food packaging is modified in an environment-friendly adhesive bonding mode. Non-toxic nonflammable alcohol-water mixed vapor is discharged in oven drying of composite production process, and therefore the manufacturing technique quality grade of composite soft packaging material products is improved well.
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-aluminum-polyethylene drug and food composite packing film.
Background technology
Polyester/aluminium/polyethylene (PET/AL/PE) drug and food composite packing film be a kind of employing intensity, transparency and rub resistance preferably biaxial stretching polyester BOPET (be called for short PET) film do the top layer; Print soft aluminium AL paper tinsel and do the intermediate layer; Low density polyethylene (the being called for short PE) film that is prone to heat-sealing bonding is made internal layer; Between layer and the layer with adhesive bonding be composited moisture, oxygen and smell are had the composite soft packaging material of good comprehensive barrier, mainly be used 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 the more anti-boiling of cementability (for sterilization); And the adhesive that can reach this requirement in the past has only the toluene or the ethyl acetate solvent borne polyurethane hot setting adhesive of non-Environmental Safety; When producing PET/AL/PE drug and food composite packing film, just used the non-Environmental Safety adhesive of this type like this; Cause poisonous toluene or the pollution of ethyl acetate solvent gas discharging and inflammable and explosive potential safety hazard to production environment, also made the sanitary toxicology property of composite membrane product itself be affected.
The utility model content
The purpose of the utility model is that environmental protection glue modified poly ester-aluminum-polyethylene drug and food composite packing film that a kind of environmental pollution is little, the boiling resistance ability is strong, rub resistance is good is provided in order to address the above problem.
The utility model is realized through following technical scheme:
A kind of environmental protection glue modified poly ester-aluminum-polyethylene drug and food composite packing film; Comprise top layer, intermediate layer and internal layer; Said top layer is the biaxial stretching polyester layer; Said intermediate layer is an aluminium foil layer, and said internal layer is a polyethylene layer, between said biaxial stretching polyester layer and the said aluminium foil layer, be provided with alcohol-water based polyurethane modified polyacrylate adhesive layer between said aluminium foil layer and the said polyethylene layer.
Employing has stronger boiling resistance alcohol-water based polyurethane modified polyacrylate adhesive; Replace original non-Environmental Safety toluene or ethyl acetate solvent borne polyurethane hot setting adhesive; Polyester/aluminium/polyethylene drug and food composite packing film is carried out bonding modification; During compound production what dry discharging is nontoxic nonflammable alcohol-water mixings gas, not only thoroughly overcome the shortcoming of existing non-environment-friendly adhesive, the while has kept the good comprehensive serviceability of this drug and food composite packing film again; Thereby promoted the production technology quality grade of this compound soft packing material product well, obtained good environment protection modification effect.
As the utility model preferably, the thickness of said biaxial stretching polyester layer is 0.01-0.03mm.
As the utility model preferably, the thickness of said aluminium foil layer is 0.02-0.05mm.
As the utility model preferably, the thickness of said polyethylene layer is 0.01-0.03mm.
As the utility model preferably, the thickness of said alcohol-water based polyurethane modified polyacrylate adhesive layer is 0.005-0.02mm.
The beneficial effect of the utility model is:
Employing has stronger boiling resistance alcohol-water based polyurethane modified polyacrylate adhesive; Replace original non-Environmental Safety toluene or ethyl acetate solvent borne polyurethane hot setting adhesive; PET/AL/PE drug and food composite packing film is carried out bonding modification; During compound production what dry discharging is nontoxic nonflammable alcohol-water mixings gas, not only thoroughly overcome the shortcoming of existing non-environment-friendly adhesive, the while has kept the good comprehensive serviceability of this drug and food composite packing film again; Thereby promoted the production technology quality grade of this compound soft packing material product well, obtained good environment protection modification effect.
