For years Canadian pet food manufacturer Martin Pet Foods has relied on pinch-bottom bags for its 7- and 15-kg (15.4- and 33-lb) sizes of "super premium" pet food.
For smaller sizes however no supplier offered a pinch-bottom bag. So for these sizes the Elmira Ontario division of H.J. Heinz was forced to settle for a multiwall flat-bottom bag even though management would have preferred a pinch-bottom bag because of its superior stackability and its ability to stand up. Martin finally got the pinch-bottom bag it wanted for its small sizes when Bancroft Bag (W. Monroe LA) introduced its "Mini Pinch" line. Martin now packages its Techni-Cal® cat food in 2- and 3-kg (4.4- and 6.6-lb) Mini Pinch bags sold in Canada Europe and Asia. The bag is being considered for other pet food products as well. The Mini Pinch bag is made of a multilayer construction comprising inside to out 1-mil biaxially oriented polypropylene/two layers 40# kraft paper/41# clay-coated stock treated with 3M's (St. Paul MN) FC-807A Scotchban(TM)/UV lacquer. It's said to provide insect resistance and a strong odor barrier. Heat sealing provides sift-resistance says Bancroft. Martin Pet Foods president Tim Martin says heat sealing required slight modifications to the packaging line. He adds that he likes the way the bag has solved problems with wicking and infestation-serious concerns when dealing with overseas shipping. "The pinch-bottom bag in this small dimension opens up a whole new opportunity for us" says Martin.
