Bancroft has been a manufacturer of Woven Polypropylene IBC’s (Bulk Bags) for over twenty-five (25) years and is also a proven supplier of a wide range of WPP shipping sacks supplying the feed and pet food, as well as, horse and other large animal feed industries. We offer custom size and construction with up to eight (8) color process printing. Our bags are constructed using 100% virgin resin that is 100% food grade material.
Bancroft WPP shipping sacks have been analyzed at Rutgers University and passed their testing for palatability. Sacks were tested, as compared to standard paper multi-wall pet food bags. Testing determined that there were no off-odors or extractables and that Bancroft WPP sacks contained no inorganic (heavy metal) and are within FDA compliance standards. Further testing at Michigan State School of Packaging concluded that both reverse printed and surface printed sacks survived over 111 drops (testing stripes) with no failure and with “rub” results over three (3) times greater that printed paper multi-wall bags.
