Description
Technical field
The invention belongs to packaging material field, it is related to a kind of aluminium-foil paper, specifically a kind of aluminium-foil paper being combined without glue.
Background technology
Aluminium foil has that light weight, ductility are good, barrier is high, nontoxic, lower-price characteristic, is widely used as all kinds of compound
The barrier layer of packaging material.Aluminium foil paper packing material can give full play to the advantage of aluminium-foil paper, can increase substantially packing timber
The performances such as the barrier of material, waterproof and dampproof property, printability and heat sealability, thus receive packaging industry and the favor of user.So
And traditional aluminium-foil paper needs to use the intermediate layer with bonding force that aluminium foil and aluminum foil backing paper are bonded together to form aluminium
Foil paper.
The method commonly used on current aluminium-foil paper combination process is that dry laminating and wet method are compound.Compound so-called wet method is to glue
Mixture is uniformly coated in aluminium foil or aluminum foil backing paper substrate, is then combined aluminium foil and aluminum foil backing paper under pressure, so
The solvent in adhesive is vapored away by baking oven afterwards.And dry laminating refers to adhesive being spread evenly across aluminium foil or aluminum foil lining
In paper substrates, will under pressure it be combined again after solvent volatilization in adhesive by baking oven.However, either dry laminating
Or wet method is compound to be required for using substantial amounts of organic solvent, huge pollution is caused to environment, increasingly focusing on low-carbon, be good for
Health, safety and environmental protection, today of resources conservation and green ecological, to consuming the negative effect that so substantial amounts of organic solvent is brought
Increasingly paid close attention to by people.Aluminium-foil paper is compound due to the volatilization of no solvent without glue, environmentally safe, thus enjoys
Concern.However, up to the present, the preparation method of the relevant compound aluminium foil of aluminium-foil paper and the report of technology are very few, and this is also to lead
Current aluminium-foil paper is caused without the compound also key factor without large-area applications of glue.Therefore, a kind of aluminium-foil paper is invented without the compound use of glue
The preparation method of aluminium foil is for promoting fast development of the aluminium-foil paper without glue composite industrial, reduction aluminium-foil paper laminating production to environment
Influence has very important significance.
