RFIBER pitches scrim reinforcement for foil, PET and kraft composites

Shanghai Ruifiber Industry says its laid scrim products strengthen aluminum foil, PET film and kraft paper laminates for construction, packaging and industrial uses. The company is targeting manufacturers that want thinner, lighter composites with better tear resistance and burst strength.

Why it matters: - RFIBER is targeting a core problem in thin-material manufacturing: how to keep lightweight laminates from tearing, puncturing or delaminating under real-world stress. - The approach could help manufacturers use less base material while keeping composites usable in HVAC, packaging and industrial transport. - The company is positioning scrim reinforcement as a way to improve durability without major changes to existing lamination lines.

What happened: - Shanghai Ruifiber Industry Co., Ltd. promoted its scrim solutions for aluminum foil, PET film and kraft paper composites in a release dated Aug. 19, 2026. - The company says it operates a manufacturing base of more than 20,000 square meters in Fengxian, Xuzhou, and is headquartered in Shanghai. - RFIBER has focused on research, development and distribution of high-performance materials since 2018. - The company describes itself as a China leading scrim solution supplier for aluminum foil, PET film and kraft paper composites.

The details: - Laid scrim is a non-woven mesh made of glass fiber or polyester. - RFIBER says its scrims are used as an internal reinforcement layer in lamination to add tensile strength and stop tears from spreading. - Aluminum foil composites are a target for FSK and PSA tapes, where scrim reinforcement helps prevent crinkling and tearing during installation. - In HVAC uses, the scrim is intended to help duct wrap hold its shape under moving air and thermal expansion. - PET film composites are aimed at heavy-duty tarpaulins, sailcloth and automotive airbags that need higher burst strength. - RFIBER says its polyester laid scrims preserve flexibility and avoid the bulk associated with thicker woven reinforcements. - Kraft paper composites are aimed at multi-wall bags and other industrial packaging that must survive high-speed filling, dropping and rough logistics. - The company says the scrim helps paper stretch enough to absorb impact while keeping a rigid structure for stacking and palletization. - RFIBER says the open-mesh design lets adhesive penetrate through the grid, improving bond strength and reducing delamination risk. - The company says laid scrims offer a higher strength-to-weight ratio than woven alternatives and provide high modulus for dimensional stability. - RFIBER says its scrims are compatible with hot-melt, water-based coating and solvent-based adhesive lamination processes. - The flat structure is designed to feed smoothly through rollers and reduce wrinkles or jams. - The release cites other uses including roof insulation, composite bags, wrapping materials, truck side curtains and pool liners. - The company includes more information for technical specifications and application range. - RFIBER also lists social channels on LinkedIn, Facebook, YouTube and X.

Between the lines: - The release is as much a product positioning piece as a technical announcement, with RFIBER framing scrim as an enabling layer rather than a visible component. - The strongest commercial message is compatibility: the reinforcement is meant to fit existing composite products and manufacturing methods instead of forcing a redesign. - The focus on lightweighting suggests RFIBER is pitching durability gains alongside material and logistics efficiency.

What's next: - Manufacturers looking at foil, PET and kraft laminates may use scrim reinforcement to improve tear resistance, burst strength and process stability. - RFIBER appears to be seeking broader adoption across construction, packaging and transportation composites through both standardized and customized scrim solutions.

The bottom line: - RFIBER is betting that invisible reinforcement can become a visible competitive advantage for thin, high-performance composites.
