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.
