The manufacturing craft comprises the following steps: (1) depositing aluminum layer on the base layer to form the complex of base layer and aluminum layer; (2) coating adhesive on the complex of base layer and aluminum layer to composite the outer layer. The invention improves the stripping strength and heat-sealing strength as well as pressure-resistance strength.
Description
(1) technical field
The present invention relates to a kind of compound packaging film and manufacturing process thereof, relate in particular to a kind of composite fluid packaging film of high-barrier.
(2) background technology
The material that the present common liq packaging film that uses mainly adopts is the blend monofilm of LLDPE (LLDPE) and hp-ldpe (LDPE).Though easy to process, with low cost, material environment friendly, but because the polyethylene kind film is bad to the barrier property of light, gas, the liquid substance of internal memory is easily oxidized and waited by the ultraviolet ray irradiation and influence the quality of this material, and as nutrition taste color and luster etc., the shelf-life is shorter.
For extending the shelf life, a lot of packings have been used the material of high-barrier.High barrier material is defined as: 20 ℃, 65% humidity, 24 hours every cubic metre of oxygen transit doses are lower than 10 cubic centimetres material.What meet this requirement has inorganic material such as glass, tinplate, aluminium and ethylene-vinyl alcohol copolymer (EVOH), polyvinylidene chloride minority macromolecular materials such as (PVDC).
The patent No. is that 03231312.8 utility model patent discloses a kind of " high-barrier composite fluid packaging film ", reach the effect of high-barrier by evaporation aluminium lamination in basic unit, but the complex of basic unit and aluminium lamination is the hydrostomia extrusion composite technology with outer employing, and also there is very big room for improvement in the composite membrane that this technology is made on performance.

The objective of the invention is to solve existing high-barrier composite membrane because manufacturing process causes the limited deficiency of properties of product, the manufacturing process of the better high-barrier composite membrane of a kind of performance that manufactures a product is provided.
For this reason, technical scheme of the present invention is:
A kind of manufacturing process of high barrier aluminum-plating composite film, described packaging film comprises basic unit, sandwich layer and skin, described basic unit is the PE layer, described sandwich layer is the aluminium lamination that is coated with in the basic unit, skin is the PE layer, the complex of sandwich layer and basic unit is undertaken compound by adhesive and skin, described manufacturing process comprises the steps: (1), in basic unit evaporation one deck aluminium lamination, form the complex of basic unit and aluminium lamination; (2), coating binder and outer dry type is compound gets final product on the complex of basic unit and aluminium lamination.
Further, be printed on ink lay on the described skin, be imprinted on the described outer inner surface in before in advance with described ink lay in manufacturing technology steps (2).
Outer surface is printed on ink lay on the described skin, before or after manufacturing technology steps (2) the high temperature resistant printing ink of anti-the hydrogen peroxide is imprinted on the outer outer surface.
Described outer PE is the clear PE layer.
Be coated with ink lay on the described outer field outer surface, complex protection PE layer again outside ink lay.
In manufacturing technology steps (2) before, will be coated with ink lay on the outer field outer surface in advance, complex protection PE layer again outside ink lay.
In manufacturing technology steps (2) afterwards, will be coated with ink lay on the outer field outer surface, complex protection PE layer again outside ink lay.
Described protection PE layer is transparent.
The invention has the beneficial effects as follows: the complex of basic unit and aluminium lamination adopts the dry type complex method with outer compound by adhesive, and the composite membrane that this complex method is made through evidence, has improved peel strength, heat seal strength and compressive resistance greatly; On outer field outer surface, be coated with ink lay, the composite membrane of complex protection PE layer again outside ink lay, combined strength bination is higher, and withstand voltage, anti-drop performance is stronger; Outer surface is printed on ink lay on the described skin, and the high temperature resistant printing ink of anti-the hydrogen peroxide is imprinted on the outer outer surface, and this composite membrane is suitable for all kinds of automatic packaging machines, and is applied widely.
