These bags belong to advertising bags, because they are suitable for the promotion of any company, firm or brand. They are most often used because they are produced in different sizes and thus meet different conditions. Bags can be supplied in bundles and on an endless roll. By arrangement, made bags can be in different colors. Also, all bags can be with or without the press. Depending on the customer’s wishes, the size and thickness of the bag, the type of printing also depends. The most common type of printing is offset and digital printing. As a special category of polyethylene bags, we distinguish bags made of high-quality and biodegradable material (50 microns), which means that they minimally harm the environment we protect.
