Polypropylene (“poly”) bags are economical and a great value for the money.
They are suitable a variety of products, such as dried fruits, nuts, cookies, spices and chocolate. Other popular uses include photos, flower sleeves, portfolios, stationary, loudspeakers, carpets, potpourri, soap, gifts and sterile products. Polypropylene bags must be heat sealed, taped or tied for closure to protect the contents enclosed within. Unlike cellophane bags, poly bags do not have a natural dead-fold, so they are sealed by use of heat, fabric, yarn, ribbon or twist ties.
