Abstract

The invention provides a method for performing locally printing plate aluminum on a package film. The method comprises the following steps: a) performing graphic printing on a corona surface of a base material, wherein the base material is a transparent or semi-transparent thin film; b) drying the corona surface of the base material, performing full printing to plate the aluminum, washing the corona surface of the base material in water, and drying the corona surface of the base material after the corona surface of the base material is washed; c) compositing at least one layer of transparent material on the printed surface of the dried base material to obtain an aluminum-plated washed product. The printed patterns on the product manufactured by the method are full and bright; the problem that the aluminum cannot be completely cleaned is solved, and the rejection rate is low; no alkaline substance and no alkaline oxidized substance are stuck to a package bag; therefore, the package bag is environment-friendly, and waste aluminum is easy to recycle.

Description

The method of packaging film local printing of aluminized

Technical field

The present invention relates to packaging film print field, refer to especially a kind of method of packaging film local printing of aluminized.

Background technology

Aluminized complex film is by the metallized films such as VMPET, VMBOPP, VMCPP or VMPE and the compound and flexible packing material of a kind of barrier having had with aluminium gloss of forming of transparent plastic film, it has good metallic luster, good barrier property, convenience, the advantage such as inexpensive and is widely used in the external packing of food, health products, medicine, cosmetics, especially on dry, dilated food.

The alkali cleaning product of aluminizing: at the face of the aluminizing printed patterns of the base material of aluminizing (as VMBOPP, VMPET etc.); non-washing in aluminium place protected ink; after alkali cleaning; after the aluminium lamination and alkali oxidation reaction at not upper protection ink place; aluminium lamination is washed off, becomes transparent window, thereby solves the object that the packaging product of aluminizing can local be seen content; impel consumer's desire to buy, very attractive in appearance again.The alkali cleaning product shortcoming of aluminizing: 1. can shade after printed patterns alkali cleaning, pattern is brightless is just not attractive in appearance yet.When 2. printing occurs that cutter line, version dirt etc. are abnormal, during alkali cleaning, aluminium lamination does not wash clean, and scrappage is high.3. the material such as alkali and aluminium oxide is attached to packaging bag, unhelpful to health.4. after alkali cleaning, generate aluminium oxide, contaminated environment.
