It is a flat bag or also known as a "Pillow Pack" that can be manufactured with 2 or up to 3 seals. They can be manufactured in small sizes for products that need to be hung on the shelf by adding a "punched hole" or "Euroslot", which are tools that we already have for our standard size bags, or they can also be manufactured in larger sizes for the Food Service market including vacuum packing. The type of bag allows them to be used to pack a wide variety of dry, wet or liquid products. They can be manufactured in different types of laminated materials depending on the needs of each product. They can be manufactured with or without zipper.
