The JLW-329 Single Sided Cross Filament Tape is an industrial-grade adhesive solution engineered for the most demanding applications. Reinforced with a continuous bidirectional fiberglass grid, this high-performance cross filament tape delivers exceptional tear resistance and high tensile strength in both longitudinal and transverse directions. Designed primarily for heavy-duty packaging, bundling and palletizing, and structural reinforcement, it features a robust synthetic rubber adhesive that bonds instantly to corrugated surfaces and metal substrates. Beyond manufacturing excellence, we provide comprehensive custom OEM services, including customized slit widths, tailored roll lengths, and private labeling to perfectly match your technical specifications and production requirements.
Product Features

JLW-329 is a transparent and high strength bi-directional filament tape. Glass fiber contributes higher tensile strength and improved synthetic rubber delivers stronger adhesion; generating bi-directionally strengthened effect; high resistance to abrasion; impact resistance and high holding power.
