Top block bottom paper bags with window manufacturers for food packaging

Kolysen can produce all kinds of bags, such as paper and plastic flat bottom bags, block bottom bags, square bottom bags, box bags, coffee pouches, box bags with valves, flat bottom coffee pouches, box bottom bags, and so on. We can also add zippers to the pouch as an option.

Our pouches can be fitted with a one-way degassing valve for baking coffee packaging. We can also use this bag for dog dry food or larger packaging because the bag style allows for higher filling capacity thanks to corner braces on the sides and bottom.
