Description
Technical field
The invention belongs to packaging material and its preparing technical field, and in particular to a kind of plastic-aluminum without glue it is compound with aluminium foil and its
Preparation method.
Background technology
Aluminium foil has that light, ductility is good, barrier is high, nontoxic, lower-price characteristic, is widely used as all kinds of compound
The barrier layer of packaging material.Aluminium plastic composite packaging material can give full play to the advantages of aluminium foil and plastics, can increase substantially
The performance such as the barrier of packaging material, waterproof and dampproof property, printability and heat sealability, thus receive packaging industry and the green grass or young crops of user
Look at.But traditional aluminum-plastic composite membrane need to use the intermediate layer with bonding force by aluminium foil and plastic sheeting be bonded together from
And form aluminum-plastic composite membrane.The method commonly used at present on plastic-aluminum combination process is that dry laminating and wet method are compound.So-called wet method is answered
Conjunction is that adhesive is uniformly coated on aluminium foil or plastic sheeting substrate, then by aluminium foil and plastic sheeting under pressure
It is compound, then the solvent in adhesive is vapored away by baking oven.And dry laminating refers to adhesive being spread evenly across aluminium foil
Or in plastic sheeting substrate, will be compound under pressure 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, is increasingly being noted
Today of low-carbon, health, safety and environmental protection, resources conservation and green ecological again, brought to consuming so substantial amounts of organic solvent
Negative effect had been to be concerned by more and more people.Plastic-aluminum is compound because no solvent volatilizees without glue, environmentally safe,
Thus receive much concern.However, up to the present, the report about the plastic-aluminum combined preparation method with aluminium foil and technology is very few, this
And cause current plastic-aluminum compound also without the key factor of large-area applications without glue.Therefore, it is compound without glue to invent a kind of plastic-aluminum
With the preparation method of aluminium foil for promoting fast development of the plastic-aluminum without glue composite industrial, reducing shadow of the plastic-aluminum combined production to environment
Sound has very important significance.
