Non-woven laid scrims laminated for flex duct packaging

Non-woven laid scrims Introduction

This product is a Laid Scrim​ (glass, polyester, or hybrid), a cost-effective, open-mesh reinforcement fabric engineered for lamination into flex duct packaging and HVAC flexible-duct composites​ — where the scrim sits as the hidden tensile grid between aluminum foil, PE, and non-woven / fiberglass tissue layers that form the duct facing or outer wrap. It is manufactured by chemically bonding continuous filament yarns (Glass, Polyester, Carbon, Cotton, Flax, Jute, Viscose, Kevlar, Nomex, etc.) into a flat-laid open mesh (square or tri-directional), with binder options (PVOH, PVC, Acrylic, or customized) to match foil–non-woven laminating and flex-duct wrapping lines. Thanks to lightweight, high strength, low shrinkage/elongation, and corrosion resistance, the scrim offers measurable value versus conventional reinforcement concepts and bonds readily with many material systems common to flex duct and packaging converters. 

Non-woven laid scrims Characteristics

Non-woven laid scrims Application

Primary Use: Laminated reinforcement in Flex Duct & HVAC Duct Packaging

The core application of this laminated laid scrim is as the hidden tensile grid laminated between aluminum foil / PE face and the non-woven or tissue backing​ in flex duct jackets, duct-wrap facings, and insulated duct packaging sets. It is sandwiched into the duct composite to:

Prevent Tear During Duct Bending, Handling & Installation

Flex ducts are bent around elbows, compressed into cartons, and handled on-site. The scrim absorbs winding and handling stress, arrests tear propagation at seams and grommet zones, and keeps the vapor-barrier facing continuous — critical for HVAC thermal efficiency and condensation control.

Maintain Dimensional Stability on Wrapping Lines

The scrim’s low elongation keeps the foil–non-woven facing flat through winding, compression packaging, and in-service thermal/humidity cycles, preserving lap-seal integrity on spiral-wrapped ducts and packaged sets.

Extend into Broader Packaging Composites

Beyond flex duct, the same laminated scrim platform also feeds envelopes, cardboard containers, transport boxes, anticorrosive paper, air-bubble cushioning, paper bags with windows, high-transparent films​ under the Packaging category — wherever a converter needs a lightweight tensile grid laminated into paper, film, or non-woven stacks.

Secondary Applications

a) Aluminum Foil Composite

b) PVC Flooring

c) None-woven category products reinforced

d) PVC Tarpaulin

Laid scrim can be used as basic materials to produce truck cover,light awning, banner, sail cloth etc.

Due to lightweight, high strength, low shrinkage/elongation, corrosion preventive, laid scrims offers tremendous value compared to conventional material concepts. And it’s easily to laminate with many kinds of materials, this makes it has an extensive fields of applications.
