PE Coated Woven Fabric is a functional composite material consisting of a woven base fabric coated with a Polyethylene (PE) layer.
Base Fabric Layer: Typically woven from PP (Polypropylene) or PET (Polyester) flat yarns, providing tensile strength and tear toughness.
Coating Layer: A PE layer extrusion-coated on one or both sides of the base fabric, providing water resistance, impermeability, UV resistance, and edge-sealing properties.

Waterproof & Moisture-proof: The PE coating effectively blocks the penetration of water, moisture, and liquids.
High Strength & Tear Resistance: Thanks to the internal woven mesh structure, it can withstand heavy tension and is resistant to puncture or tearing.
Weather & UV Resistance: UV stabilizers are typically added during production to prevent aging and degradation when exposed to sunlight outdoors.
Chemical Resistance: Exhibits good resistance to most acids, alkalis, and chemicals.
Lightweight & Cost-Effective: Offers an extremely high strength-to-weight ratio compared to other heavy-duty engineering materials, providing excellent cost-efficiency.
Roof Decking & Attic Insulation: Installed under roof tiles, metal sheeting, or rafters as a secondary waterproof and radiant barrier membrane.
Wall Wraps & Thermal Breaks: Placed behind exterior cladding to manage condensation and block radiant transfer.
Industrial & Agricultural Sheds: Frequently used as an exposed interior roof and wall liner for large-span steel buildings, warehouses, and poultry farms to regulate internal temperatures.
Used as a facing or jacketing material for thermal insulation blankets, glass wool, rock wool, and flexible air conditioning ducts to prevent energy loss and vapor ingress.
Export Tarpaulins & Machinery Covers: Utilized to wrap large industrial machinery, steel coils, and moisture-sensitive goods during maritime or long-term outdoor storage.
Container Liners: Sewn into custom shapes to line shipping containers, protecting bulk products from sweat, moisture damage, and radiant heat shifts.
The production process of PE coated woven fabric is mainly divided into two core stages: base fabric manufacturing and lamination (coating).
Blending & Mixing: Thoroughly mix HDPE/LLDPE resin with additives such as UV stabilizers and masterbatches.
Extrusion & Slitting: Melt and plasticize the mixture at high temperatures to extrude a film, then cool and slit it into fine "flat yarns."
Stretching & Annealing: The flat yarns undergo high-ratio longitudinal stretching via heating to achieve molecular orientation, which significantly increases tensile strength, followed by heat-setting.
Weaving: Interweave the flat yarns using circular looms or water-jet/flat looms in warp and weft directions to form PE woven greige cloth with a specific density.
Melt Extrusion: Heat and melt LDPE resin, then extrude it through a T-die to form a continuous, high-temperature molten film.
Compound Pressing: Synchronously feed the high-temperature molten PE film and the PE woven fabric into the nip rollers. Under pressure, the molten PE penetrates into the mesh of the woven fabric and bonds tightly (available in single-sided or double-sided coating).
Cooling & Solidification: Cool through cooling rollers to allow the PE coating to solidify rapidly and integrate seamlessly with the base fabric.
Trimming: Cut off redundant selvages on both sides of the composite fabric.
Winding & Slitting: Slit and rewind into rolls according to the specifications required by customers.
Quality Control: Test the weight (GSM), thickness, tensile strength, coating adhesion strength, and waterproof performance before packaging and shipping.
Adhesion Strength: The temperature of the molten PE, extrusion speed, and roller pressure are critical factors determining whether the coating is prone to peeling. Temperatures that are too low lead to poor bonding, while temperatures that are too high can deform or break the flat yarns.
Thickness & GSM Uniformity: Precise control of the extrusion speed and base fabric traction speed is required to ensure consistent coating thickness and total weight per square meter (GSM) across the entire roll.
Anti-Aging Performance: For outdoor applications, the dosage and uniform dispersion of UV stabilizers directly determine the product's lifespan under prolonged sunlight exposure.
PE is lighter, more eco-friendly, and has good weldability, though its temperature resistance and wear resistance are slightly lower.
With the addition of the woven layer, puncture resistance and longitudinal/transverse tensile strength are dramatically enhanced, preventing it from easily tearing apart.
