Berstorff line arrives ready-to-roll in China
Berstorff Corp. of Florence, Ky., has built and shipped a complete compounding system for a new company in China.
The Chinese company, North Degradable Plastics Factory, is based in Gaobeidian, Hebei Province. The company converted its building from a military factory to an additives manufacturing plant, manufacturing additives for making plastics degradable.
Berstorff developed the skid-mounted compounding system with Willow Ridge Plastics Inc. a company in Erlanger, Ky., that makes additives used in degradable plastic bags and films.
The skid-mounted compact compounding system integrates a Berstorff ZE twin-screw extruder and auxiliary equipment, including a vacuum pump, three feeders, and one crammer feeder. The system was shipped entirely assembled, fully pretested and ready for production.
Berstorff President Nelson Hopcus and Willow Ridge President William Hogan both point to the ease of setup as a huge factor in the sale to the Chinese company. Hogan said that the skid-mounted system was ``the best way to convert [the building] from a military factory to peacetime usage.''

Presto's new zipper curbs contaminants
Presto Products Co. has introduced a contaminant-resistant zipper with a design the company says keeps out particles from the closure, a factor which may have kept some customers from looking at flexible packaging.
The Fresh-Lock zipper-style 140 has reconfigured male and female closures that channel particles outward and away from the zipper track. It also has a low, wide interior base that keeps stray particles from entering the locking mechanism.
The bag has a two-layer coextruded low density polyethylene structure with an ethylene vinyl acetate sealant. Presto, in Appleton, Wis., is a subsidiary of Reynolds Metal.

Firm touts low cost cross-linked PE foam
Sentinel Polyolefins has developed a cross-linked polyethylene foam with a density of only 1.5 pounds per cubic foot, letting it offer the mechanical properties of cross-linked foams at prices comparable to noncross-linked foams.
The SSP-15 material is made with a nonflammable blowing agent, rather than isobutane in traditional applications. As a result, no special conditions are required for handling and storage.
The foam is available in bun form of 60 by 96 inches, and 4 inches thick, without lamination. It is designed for packaging applications where an exposed part must remain in the same condition as when it was originally produced, such as an automotive interior. Sentinel is based in Hyannis, Mass.
