Abstract
A kind of novel aqueously to mould-aluminium-mould structure composite film, comprise outer layer plastic film, soft aluminium foil, inner plastic film.Wherein all bond by water-base cement between soft aluminium foil layer and ectonexine plastic sheeting, Aqueous Adhesives is double-component waterborne polyurethane compound adhesive, by aqueous polyurethane dispersing liquid host with water-based isocyanate curing agent is composite forms.T-shaped peel strength >=1.5N/15mm between outer layer plastic film layer and middle aluminium foil layer, T-shaped peel strength >=2.5N/15mm between middle aluminium foil layer and inner plastic thin layer.The utility model overcome existingly to mould-aluminium-mould structure composite film producing and in use procedure, organic solvent brings that some endanger.Provide and a kind of can be suitable for existing dry laminating device fabrication, while the product performance index water-based that meets the requirement of existing use solvent-borne type composite membrane mould-aluminium-mould structure composite film.
Description
Technical field
The utility model relates to a kind of plastic-aluminum structure composite packaging film, particularly relate to a kind of water-based to mould-aluminium-mould structure composite film.
Background technology
The production method of aluminum-plastic composite membrane mainly extrudes compound and dry laminating, and composite dry process is applicable to the compound of various film substrate.Aluminum-plastic composite membrane can meet the performance requirement such as heat-resisting, cold-resistant, oil resistant, acidproof, drug-resistant, choke, transparent, wear-resisting and puncture-resistant.
Composite dry process is prepared composite membrane for solvent-based adhesive and be there is shortcoming, and a large amount of solvent volatilization not only causes environmental pollution, and the residual solvent in composite membrane also can have influence on food and medicine quality and safety.At present before America and Europe uses the compound package material of solvent-based adhesive from 10 years 80% reduces to current about 30%.What in current domestic thousands of composite packaging production lines, major part still adopted is solvent-based adhesive, China's export to Japan, European Union the food such as tealeaves, mushroom, meat, all once because safe and sanitary problem is return.Therefore, food and medicine health and packaging not only threaten the health of people, also have impact on the export economy of China.Along with the continuous enhancing of people's environmental consciousness, the greenization of food and medicine packaging material, environment-friendly type will more and more come into one's own.
For our packaging industry itself, conventional aluminum-plastic composite membrane is in production and application process, owing to being subject to technique restriction, the safety and sanitation performance requirements such as dissolvent residual, evaporation residue, readily oxidizable substance index, Solvent migration amount and primary aromatic amine are usually not up to standard.Some product dissolvent residual index is even above standard and requires several times, badly influences the quality standard of product.
Summary of the invention
Technical problem to be solved in the utility model be existingly to mould to overcome-aluminium-mould structure composite film producing and in use procedure, organic solvent brings that some endanger.Thering is provided a kind of and can be suitable for existing dry laminating device fabrication, the water-based that product performance index meets the conventional solution-type composite membrane of present use simultaneously moulds-aluminium-mould structure composite film.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of water-based moulds-aluminium-mould structure composite film, be characterized in: comprise intermediate layer aluminium foil, the outer adhesive linkage of aqueous adhesive is had at the outer surface even spread of aluminium foil, the outer surface of the outer adhesive linkage of aqueous adhesive is compounded with outer layer plastic film, the outer T-shaped peel strength >=1.5N/15mm of adhesive linkage between outer layer plastic film and aluminium foil of aqueous adhesive; Adhesive linkage in the inner surface even spread one deck aqueous adhesive of aluminium foil being compounded with outer layer plastic film, in aqueous adhesive, the outer surface of adhesive linkage is compounded with inner plastic film, the T-shaped peel strength >=2.5N/15mm of adhesive linkage between aluminium foil and inner plastic film in aqueous adhesive.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, described aqueous adhesive is by aqueous polyurethane dispersing liquid host and the composite double-component waterborne polyurethane compound adhesive of water-based isocyanate curing agent, and the surfaces externally and internally being spread evenly across aluminium foil forms inside and outside adhesive linkage.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described aluminium foil layer is soft aluminium foil layer; Thickness is 0.005-0.08mm.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described outer layer plastic film is polyester (PET) film, nylon (NY) film or Biaxially oriented polypropylene (BOPP) film, and thickness is 0.01-0.08mm.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described inner plastic film is CPP film (cast polypropylene) or PE film (polyethylene), and thickness is 0.03-0.1mm.
The utility model compared with prior art, 1, use water-base cement as moulding-composite adhesive of aluminium-mould structure overcomes composite membrane in some harm of producing and in use procedure, organic solvent brings.Meet the demand of national development environmental protection industry.2, existing dry laminating device fabrication can be suitable for, not need to transform current device, saved entreprise cost; Water-base cement is compared with solvent-borne type glue simultaneously, and use water to replace organic solvent, energy-saving and emission-reduction reduce costs.
