Block bottom bags with sealed bottom are made of OPP 40 my, transparent (unprinted). Thanks to the sealed bottom, the bags are 100% closed so that they are leak-proof. A sealed bottom is stronger than a stuck bottom.
Polypropylene was developed in the fifties and is resistant to chemical solvents, alkali, acids, and also against the growth of bacteria.
