OPP bags are made of two layers of polypropylene film, which gives them excellent moisture barrier, high clarity and good tear strength. Therefore, OPP bags are ideal for packaging of various types of food products such as chocolate, pralines, cookies, tea, coffee, sugar, rice, dried fruit and many others.
They can be printed in up to six colors and produced as:
1. OPP bags with glued seam and folded bottom, which is additionally attached with glue, or
2. OPP bags with longitudinal welding in the middle of the bag and welding at the very bottom of the bag.
