Why is BSTMELT’s WG series strapping often called "Synthetic Steel"? The answer lies in the rigorous material science behind it.
The core component is High-Tenacity Industrial Polyester Yarn. This material possesses a high degree of molecular orientation, giving the strap its incredible tensile strength. During production, multiple strands of polyester fibers are laid parallel and encased in a high-performance hot melt glue. This structure ensures that even if the strap is partially nicked longitudinally, it will not unravel like woven strapping.
The Shock Absorption Effect: Physical parameters show that BSTMELT WG straps have a specific elongation rate (usually between 10%-15%). This is a key advantage, not a flaw. When a shipping container receives a sudden impact, the WG strap acts like a "spring," absorbing the energy and snapping back, whereas a steel strap might snap instantly due to its lack of elasticity.
Synergy with Buckles: The galvanized buckles included in the kits are precision-engineered. When the strap is threaded and tightened with a manual tool, the hot melt adhesive layer creates massive static friction against the steel surface of the buckle. This dual mechanism of "chemical bonding + mechanical interlocking" ensures that the joint efficiency is far superior to that of ordinary plastic seals.
Through continuous R&D, BSTMELT ensures that every roll of 13mm and 16mm strapping performs reliably under extreme conditions, providing technological support for global industrial packaging.
