Embodiment 1

[0020] Embodiment 1: A kind of partial aluminized packaging film does not need to be aluminized on the BOPP plastic film at first

[0021] The parts are coated with water-based composite glue. The water-based composite glue is the water-based composite glue H-33 produced by Houjingsheng Industrial Co., Ltd., followed by vacuum aluminum plating, the thickness of the aluminum layer is 0.03-0.05um, and then the film is placed in the washing tank In the middle, rinse with water, because the water-based composite glue is under the part that does not need aluminum plating, so when washing with water, the water-based composite glue will dissolve in water, and will be washed together with the upper aluminum layer to achieve the purpose of partial aluminum plating . Finally, offset printing technology is used to print the required text pattern on the film.

Abstract

The invention discloses a partially-aluminized packaging film and a manufacturing method thereof. The partially-aluminized packaging film structurally comprises a transparent plastic film, an aluminizing layer and a printing ink layer, wherein the plastic film is made of any one material of OPP, BOPP and PET, and the aluminizing layer is provided with at least one opening. The manufacturing method of the partially-aluminized packaging film includes the following process of coating of a water-based complex adhesive, vacuum aluminizing, washing and printing, wherein any water-based complex adhesive for food packaging can serve as the water-based complex adhesive, and any of offset printing, intaglio printing and silk-screen printing can be adopted as the printing mode. The partially-aluminized packaging film has the advantages that the manufacturing process is simple, cost is low, and no pollution is generated.

Description

technical field [0001] The invention relates to the field of packaging films, in particular to a partially aluminized packaging film and a manufacturing method thereof. Background technique [0002] Vacuum aluminized film is widely used in today's high-end and high-end food packaging because of its noble and beautiful metal texture, as well as its functions of moisture resistance and oxidation resistance. However, the current vacuum aluminum plating technology has not been able to directly complete partial aluminum plating, resulting in consumers being unable to see clearly the quality of the goods inside the packaging film when purchasing goods, thereby reducing consumption desires. Therefore, using partial aluminized packaging film to package food can protect the interests of manufacturers and consumers to the greatest extent. At present, the existing partial aluminized film production process adopts pickling or alkali cleaning technology, which is not environmentally fri...
