✔ Focused Tensile Performance with Unidirectional 增强材料

Three single strand of high-tenacity 增强材料 yarn is embedded longitudinally within the kraft paper 基材. This configuration concentrates tensile resistance along the primary 封箱 axis, preventing flap separation under 标准 transit loads.

✔ Cost-Optimized for Light-Duty Applications

The simplified single-yarn architecture is specifically designed for light-duty parcels and 标准 carton 封箱. Operators can select the appropriate tensile grade based on actual packaging requirements, avoiding over-specification and effectively reducing unit 封箱 costs. The kraft paper 基材 and starch 胶粘剂 maintain full compatibility with 标准 corrugated recycling streams and support plastic reduction initiatives in the EU and North America.

✔ Tamper-Evident Bond & Surface Adaptability

Water activation triggers starch gelatinization, forming a permanent physical and hydrogen bond with corrugated fibers. Removal attempts cause visible paper tearing, providing clear tamper evidence. The 胶粘剂 maintains reliable performance across 标准 ambient conditions and adheres effectively to lightly dusty or recycled carton surfaces.

✔ Optimized Packaging Throughput

Fully compatible with JL3® proprietary water-activated dispensers and automated carton sealers. Precision moisture delivery ensures consistent 胶粘剂 activation and single-strip 封箱, reducing material waste and increasing line speed.
