New baffle container efficient with space
Bulk-Pack Inc. of Monroe, La., has introduced a CubePak baffle container that can increase packaging space efficiency over existing bulk bags and can be constructed of totally recyclable polypropylene.
The container has 25-30 percent more capacity and stacks better for warehousing, according to Andrew Mintz, national sales manager.
"The container stays square after filling, during transportation and in storage," he said.
Bulk-Pack makes the baffle container in custom sizes to hold 20-115 cubic feet of material, generally dry, flowable powders, granules or pellets for chemicals, minerals, food stuffs, farm products or pharmaceuticals, Mintz said.
Woven PP forms the paneld, and PP or polyester can be used for threads and loops.
Bulk-Pack employs 300, has annual sales of about $18 million and produces containers in Denison, Texas; Hardeeville, S.C.; and the maquiladora Mountain Bag Manufacturing Inc. in Matamoros, Mexico.
Drug companies try disposable PE bag
Several major pharmaceutical firms in the United States are sampling a sterile, disposable sampling system from NovaSeptum AB of Nodinge, Sweden.
Using NovaSeptum tooling, custom molder I.T. Pack in Gothenberg, Sweden, thermoforms and ultrasonically welds the polyethylene bag. Each bag costs $25-$30, depending on quantities.
The system can sample injectables, fermenting products and cell cultures, said Johan Westman, president of U.S. distributor NovAseptic America Inc. In Lebanon, N.J., a 70 percent-owned subsidiary of NovaSeptum sister company Novseptic Equipment AB.
