PVC Tarpaulin & Film

According to a Google search, PVC tarpaulin and film are widely recognized for their durability and versatility in various applications, including outdoor covers, tents, and protective tarps. Made from polyvinyl chloride (PVC), these materials offer excellent resistance to weather conditions and abrasions, making them a preferred choice in many industries.

PVC tarpaulin consists of a multi-layered fabric featuring a scrim sandwiched between sheets of polyvinyl film. The scrim can be made from various materials such as cotton, fiberglass, nylon, or polyester, which significantly contributes to its strength and durability. Polyester scrim is specifically measured in denier, with heavier weights indicating higher durability. For instance, a 9×9 scrim has 9 threads per inch in both directions. In terms of vinyl, measurement is based on thickness, where 1 mil equals 1/1000 inch. Additionally, the vinyl undergoes treatment to achieve special properties such as flame retardancy, antimicrobial characteristics, antistatic properties, and ultraviolet protection. The weight of PVC tarpaulin is quantified in ounces per square yard; for example, a material of 13 oz weighs 13 ounces per square yard.

Duletai offers several common embossings, including matte, taffeta, and polished finishes, depending on the application. Banner products typically feature a matte finish for smoothness, tent products benefit from a polished finish, and hospital applications utilize a taffeta finish. The material is usually rolled onto a cardboard core, with the standard size at 3 inches in diameter, though a 2-inch core may occasionally be employed. In addition to PVC films, products can be complemented with polyurethane films, silicone coatings, and acrylic coatings. All these films and coatings are reinforced with non-woven, woven, and knit nylon and polyester fabrics. The range of PVC tarpaulin widths can vary from 1.02 m to 5.10 m, and colors can be customized based on customer needs. Our manufacturing process yields durable PVC tarpaulin materials suited for various applications, all while balancing price and delivery time.

In partnership with Rondy, we aspire to be your trusted supplier and partner, offering high-quality coated or laminated PVC tarpaulin material tailored for tents, swimming pools, boats, bouncing castles, membrane structures, ventilation ducts, truck covers, medical mattresses, and beyond, with widths up to 5.1 meters.

PVC Tarpaulin Manufacturing Processes

To manufacture PVC tarpaulin, different machines based on material specifications and required characteristics are employed:

Calendering Machine

This machine is crucial for producing PVC film, transforming raw PVC materials into paste, and then rolling them into various thicknesses. The resulting calendared vinyl films are made through an intricate process that ensures proper thickness, resulting in a high-quality finish.

Cold Lamination Machine

This machine, an early industry staple, is widely utilized for laminating PVC films onto polyester fabric. It provides a fast, efficient process at lower operational costs, though the limitation in temperature and pressure can affect durability for certain low-cost applications.

Hot Lamination Machine

This more advanced machine features a lengthy process that achieves higher temperatures and pressures. It produces high-quality materials suitable for demanding applications, incorporating additional treatments such as self-cleaning acrylic coatings.

Knife Coating Machine

Unlike laminating devices, the knife coating machine directly applies PVC resin onto fabric using a doctor blade, followed by an embossing roller for drying. This method produces a variety of heavy-duty materials with exceptional tensile strength, ideal for both permanent and temporary projects.

PVC Tarpaulin Structural Types

PVC tarpaulin structures can be categorized based on the number of layers:

2-Layer Construction

• PVC Film
• Base Fabric

Commonly used for bags and gym mats due to cost-effectiveness.

3-Layer Construction

• PVC Film
• Base Fabric
• PVC Film

This structure is widely applied in banners and tarps.

4-Layer Construction

• PVC Film
• Black Layer
• Base Fabric
• PVC Film

Effective in blocking light, suitable for banners and tents.

Maintenance Guidelines for PVC Tarpaulin

To ensure the longevity of your PVC tarpaulin, adhere to the following care instructions:

1. Avoid sharp objects to preserve waterproof capabilities.
2. Unfold and dry before storage.
3. Store in a dry place, protecting from moisture and pests.
4. Handle with care to prevent damage to packaging and insulation.
5. Maintain a safe distance from fire sources.
6. Unfold on clean ground to avoid surface damage.
7. Check surrounding conditions for winds that may require reinforcement.
