What Is PVC Coating?
Learn how PVC coating creates durable, waterproof and abrasion-resistant technical fabrics for industrial covers, bags, tarpaulins and protective textile applications.
Definition
PVC coating is a textile finishing process that applies polyvinyl chloride resin onto a woven, knitted or nonwoven fabric substrate to create a durable, waterproof and abrasion-resistant composite material. The coating forms a continuous plasticized barrier that helps block water, improve surface durability and support heavy-duty outdoor or industrial use.
PVC-coated fabrics are commonly used in tarpaulins, truck covers, industrial curtains, inflatable products, bags, luggage, outdoor covers and protective equipment. Compared with PU coating and TPU lamination, PVC coating is often selected when cost efficiency, mechanical durability and high waterproof protection are more important than soft hand feel or premium breathability.
How PVC Coating Works
PVC coating usually combines PVC resin, plasticizers, stabilizers, pigments and performance additives. The compound is applied to a base fabric and then heated so the coating gels or fuses into a continuous film.
Direct Coating
- PVC plastisol is spread directly onto the fabric surface.
- Knife-over-roll or knife-over-air equipment controls coating thickness.
- The coated fabric passes through an oven for gelation and fusion.
- Additional coating layers may be added to improve waterproofing and durability.
Dip Coating
- Fabric is immersed in a PVC compound.
- Excess coating is removed with rollers or blades.
- The fabric is heated to cure and fuse the coating.
- This method can provide strong penetration into open fabric structures.
Calender Coating
- PVC film is formed through heated calender rolls.
- The film is laminated or pressed onto the textile substrate.
- This supports smoother surfaces and controlled film thickness.
- It is often used for industrial and synthetic leather constructions.
Foam PVC Coating
- Foaming agents are added to create a softer, thicker coating layer.
- The process can improve cushioning and hand feel.
- It is used for upholstery, padding, bags and some protective fabrics.
The final material performance depends on the base fabric, coating weight, plasticizer system, curing conditions and post-finishing. Buyers should confirm performance through application-specific fabric testing.

- Chemical resistance: Many PVC systems resist oils, mild acids and common industrial contaminants.
- Weather options: UV, mildew, cold-crack and flame-retardant additives can be formulated.
- Large-format use: Suitable for tarpaulins, covers, tents and industrial sheet goods.
Limitations
- Lower breathability: PVC is generally not suitable for breathable outdoor apparel.
- Stiffer hand feel: PVC-coated fabrics can feel heavier and less flexible than PU or TPU systems.
- Cold flexibility concerns: Some formulations become stiff or crack in low temperatures.
- Plasticizer migration: Poor formulations may become tacky or lose flexibility over time.
- Environmental concerns: PVC chemistry can raise concerns around chlorine content, plasticizers and end-of-life treatment.
- Recycling difficulty: Coated textiles are difficult to separate and recycle mechanically.

FAQs
Is PVC-coated fabric waterproof?
Yes. PVC-coated fabric is generally designed to be waterproof because the coating forms a continuous barrier over the textile substrate. Final waterproof performance depends on coating weight, fabric construction, seams and testing method.
Is PVC coating breathable?
PVC coating is usually not breathable. It is best suited for covers, tarpaulins, bags and industrial textiles where waterproof durability matters more than moisture vapor transmission.
What is the difference between PVC coating and PU coating?
PVC coating is often heavier, tougher and more suitable for industrial covers or tarpaulins. PU coating is usually softer, lighter and more common in rainwear, bag linings and flexible consumer products.
What is the difference between PVC coating and TPU lamination?
PVC coating is a cost-effective waterproof coating for rugged applications. TPU lamination usually provides better flexibility, lower weight and stronger suitability for premium outdoor apparel, medical textiles and technical performance products.
Can PVC-coated fabric be welded?
Yes. Many PVC-coated fabrics can be heat welded or high-frequency welded to create sealed seams. This is one reason PVC is widely used for tarpaulins, inflatable products and waterproof covers.
Is PVC-coated fabric UV resistant?
PVC can be formulated with UV stabilizers for outdoor use. Without suitable additives, prolonged sunlight can cause fading, cracking, stiffness or surface degradation.
Is PVC-coated fabric safe?
Safety depends on the formulation and additive system. Buyers should request compliance documentation for phthalates, heavy metals, REACH and any relevant market requirements, especially for skin-contact or consumer products.
Can PVC-coated fabric be recycled?
PVC-coated textiles are difficult to recycle because the coating is bonded to the fabric substrate. Some specialized recycling routes exist, but most programs require careful material separation and controlled processing.
Why does PVC-coated fabric become sticky?
Stickiness can result from plasticizer migration, heat exposure, poor storage, chemical contamination or long-term aging. Selecting suitable plasticizers and stabilizers helps reduce this risk.
Where is PVC-coated fabric commonly used?
Common uses include truck covers, tarpaulins, tents, awnings, industrial curtains, inflatable products, waterproof bags, marine covers and outdoor protective sheets.
