Can you iron PVC coated fabric?

PVC coated fabric is generally not recommended for direct ironing.
This material essentially consists of a layer of plastic (polyvinyl chloride) coated onto the surface of the fabric. Because plastic is very sensitive to heat, direct contact with a hot iron can cause a number of problems. Here's a detailed explanation of why you shouldn't iron it directly and what to do if you need to remove creases:

1. Why shouldn't you iron it directly?

Easy to melt: The high temperature of the iron will quickly soften or even melt the surface plastic. Once melted, the PVC coated fabric will not only deform but also stick to the iron's soleplate like glue, ruining both your garment and the iron.
Surface damage: Even if it doesn't completely melt, overheating can make the coating brittle, lose its luster, or develop unsightly shiny spots, destroying its original waterproof and aesthetic properties.
Emits unpleasant odor: When heated, plastic produces a pungent odor, and prolonged inhalation of these heated fumes is not good for your health.

2. How to deal with wrinkles?

If you find noticeable creases in your PVC coated fabric, you can try the following gentler methods:
Natural hanging method: This is the safest method. Hang the item on a hanger and let gravity naturally smooth it out. For large tarpaulins or covers, spread them out on a flat surface and let them sit in gentle sunlight (avoid direct sunlight). As the material softens, the creases will gradually disappear.
Low-temperature ironing with a cloth barrier: If you absolutely must use an iron, set it to the lowest temperature. Place a thick, damp cotton cloth on the back of the PVC coated fabric (the side without the coating) as a buffer. Never let the iron directly touch the fabric, and keep the iron moving constantly; never leave it in one place.
Hair dryer method: Use a household hair dryer on the warm setting (not too hot), holding it at a distance from the creases. Once the material softens slightly, gently smooth it with your hand. This method is more controllable and much safer than using an iron.
Warm water wiping: Dampen a towel with warm water and wipe the creases, or use steam from a shower to naturally relax the material. This can also help alleviate minor creases.

3. Storage Recommendations

To avoid future problems with creases, proper maintenance is important:
Store it rolled up: When storing PVC-coated fabric, it's best to roll it into a cylinder rather than folding it into a square. Storing it rolled up will almost completely prevent permanent creases.
Avoid heavy pressure: Do not stack heavy objects on top of the folded coated fabric, as pressure is the main cause of deep creases.
