Coextruded lumber strap in use

Recently, a high quality lumber supplier, Abenaki Timber Corporation, came to us with an issue to solve. They needed extruded polypropylene profiles to be used as lumber pile reinforcements. The purpose of the plastic profile is to strengthen the stacking in containers being shipped overseas.

Initial testing of the requested product proved that an extruded profile made of solely polypropylene would be too slippery. The lack of friction allowed the load of heavy lumber to shift more easily rather than strengthening the stack.

Our team did some brainstorming and came up with a coextruded solution to meet the performance needs of the application.  Along with the base profile, we coextruded four Thermoplastic Elastomer (TPE) strips, placing two on the top of the extruded profile and two on the bottom of the extruded profile to add friction and grip. These innovative, coextruded TPE strips act successfully as a grasp to keep the load from shifting.

From brainstorming new ways to create the best product to recommending cost-saving efficiencies, the decision-makers at PBS Plastics are accessible and involved every step of the way. Flexible manufacturing processes and responsive customer service define how we work.
