What is an aluminum foil bag, and how does it differ from an aluminum-plated bag?
Release time:2019-10-30
A washed aluminum bag is also called a partially hollowed-out metallized bag. It is a composite bag made by laminating plastic film with a partially hollowed-out metallized film (or a partially de-metallized layer), resulting in partial transparency. Washing aluminum refers to removing or washing off the partial metallized layer on the film. Currently, washed aluminum bags are packaging bag products with high printing requirements and beautiful design effects both domestically and internationally. They are also a popular and advanced type of anti-counterfeiting packaging globally.
Below, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will explain the differences between washed aluminum bags and ordinary metallized bags, drawing on years of experience in producing high-quality washed aluminum bags.
Washed aluminum bags have a clear distinction from ordinary laminated metallized bags. Ordinary laminated metallized bags are entirely, or their entire front (or back), laminated with metallized film. Washed aluminum bags are different; any part of the bag that you want to have an aluminum gloss effect or a transparent visual effect can be designed and produced, without being limited to a specific location or a particular regular pattern.
From a printing perspective, washed aluminum bags have better printing effects than ordinary laminated metallized bags. In terms of decoration grade, they are more aesthetically pleasing and beautiful than ordinary laminated metallized bags. Currently, there are many different practices and operational experiences for the aluminum washing process, but relatively few enterprises can achieve large-scale, high-efficiency production. Now, some users have evolved this process into a transfer printing process, such as the metallized film washing process, which applies the aluminum washing process to cold-peel transfer printing to achieve new anti-counterfeiting and packaging display effects.
In summary, washed aluminum bags feature clear graphics, high precision, strong three-dimensionality, distinct layers, vibrant colors, smooth surface, and high wear resistance. From a commercial security perspective, it is also a packaging form with strong anti-counterfeiting properties, which helps improve product grade and added value, possessing stronger product market competitiveness.
