PU Timing Belt 150H+6APL for Packaging Machine is a specialized trapezoidal-tooth polyurethane synchronous belt exclusively engineered for medium-torque, high-frequency cyclic transmission of all kinds of automated packaging machinery. This 150H+6APL specification integrates standard 150H trapezoidal tooth profile and exclusive 6APL textured back coating structure, perfectly tailored to match mainstream fixed-size pulleys for packaging equipment. Reinforced with high-density bundled steel wire tension cores inside premium industrial-grade PU material, this professionally optimized timing belt achieves near-zero linear elongation and robust instantaneous torque resistance. Different from ordinary single-sided toothed belts that lack protective back layers and easily suffer surface abrasion in complex packaging workshops, the unique 6APL patterned backing enhances anti-slip friction and buffer capacity while resisting grease, packaging debris and dust erosion.
