Except the large packaging bag for sauce, small satchet is also very popular for carried away sauce packaging. Such as the ketchup or mayonnaise sauce we used in KFC and Mcdonald. Its fast moving consumer goods and very cheap or free cost, so traditional premade pouch is not a good choice for it. Must using this rollstock for automatic packing machine due to fast packing speed and low cost. PET/White PE is the common use material structure. For better barrier can use PET/AL/PE.
