Hear what I have to say:

Washed aluminum bags (also called partial hollow aluminum-plated bags or window bags) are the packaging with the highest printing requirements and the best design effects in China and even in the world. They are very popular in Japan and are widely used in the outer packaging of clothing, food, and toys. ; It is a partially transparent composite bag made of a plastic film composite with partial hollow aluminized film (or called partial aluminized layer de-aluminum). Aluminum washing is to remove or wash off the local aluminized layer on the film.

At present, the aluminum wash bag is a packaging bag product with high printing requirements and a beautiful design effect at home and abroad. It is also a popular and advanced anti-counterfeiting packaging in the world.

The aluminum-washed bag is obviously different from the ordinary composite aluminized bag. The ordinary composite aluminized bag is that the whole bag or the front (or back) of the entire bag is composited with the aluminized film. The aluminum washing bag is different. As long as you want which part of the bag has the luster effect of aluminum and which part has the transparent visual effect, it can be designed and produced, instead of being limited to a certain position or a certain regular pattern. In terms of printing, the washing aluminum bag is better than the ordinary composite aluminized bag. In terms of decoration grade, it is more beautiful and beautiful than the ordinary composite aluminized bag.

There are many different practices and operating experiences for the aluminum washing process, but there are still relatively few companies that can achieve large-scale and high-efficiency production. Now, some users have evolved this process into a transfer printing process. For example, the aluminized film washing process is to apply the aluminum washing process to the cold tear transfer printing process to achieve new effects such as anti-counterfeiting and packaging display.

In general, the aluminum wash bag has the characteristics of clear pictures and texts, high precision, strong three-dimensional sense, similar layers, bright colors, smooth surface, and high wear resistance. From the perspective of commercial security, it is also a packaging form with strong anti-counterfeiting properties, which helps to improve product quality and added value, has stronger product market competition, and is a more high-end packaging method.
