PU leather vs PVC: differences for bags, shoes and wallets

PU leather vs PVC is a question that comes up whenever a brand chooses synthetic leather for a finished product. A supplier writes “PU leather” or “PVC” on a note but rarely explains what that means for your bag, shoe or wallet. This note covers what can be said with a basis, what still has to be checked sample by sample and which tests are worth asking for. We use only what we read, and we mark the limits.

What PU and PVC have in common

Both are coated synthetic leathers. There is a base fabric underneath and a plastic layer on top, embossed to look like leather. A US faux leather trader’s article (2017), read on 22 Oct 2026, names polyester and polyester-cotton as common base fabrics.

So the label “synthetic leather” on a note is not enough. You need to know the coating, the base fabric and the total thickness. A note that only says “synthetic leather” leaves every one of those questions open. Reading a note line by line is covered in reading a synthetic leather supplier note.

PU leather vs PVC: where they differ

According to that article, PU is polyurethane laminated to a fabric backing. PVC is a polyvinyl chloride film, cast or calendered, layered on a fabric backing. So the formal difference lies in the coating material and in how it is applied.

The same article lists one difference in testing: PU is put through a hydrolysis test, which checks how the coating holds up in a hot, humid chamber. Its example is ISO 1419 Method C, 5 weeks at 158 F and 95% humidity, as a US upholstery reference minimum. It also warns that chamber weeks do not equal years of real use.

Beyond that we found no data sheet that sets PU and PVC side by side with figures. Workshop beliefs, for example about softness or coating life, are unproven here. Treat them as hypotheses to test on each sample.

A comparison you can fill in yourself

This table is a list of questions, not answers. Fill it with data from each supplier.

What to ask	PU	PVC
Coating material.	Polyurethane.	Polyvinyl chloride.
Base fabric.	Ask: woven, knitted or non-woven.	Ask the same.
Total thickness and weight.	Get figures and tolerance.	Get figures and tolerance.
Hydrolysis test.	Ask for the method and result.	Usually not applied, so ask.
Coating adhesion.	Ask for method and result.	Ask for method and result.
Flex and rub resistance.	Ask for cycle counts.	Ask for cycle counts.

Compare two samples only when thickness and test direction match. Figures from different methods or units cannot be read side by side.

For bags, shoes and wallets

The choice depends on how the product is used, not on the material name.

• Bags get rubbed and exposed to sweat. Ask about rub resistance and coating adhesion.
• Shoes bend repeatedly at one point. Ask about flex endurance and what the coating does after many bends.
• Wallets are folded and opened daily. Ask about flex endurance at the edge, and check the fold after a few hundred bends with simple workshop checks.

The general guide by product type is on the choosing a material page.

Why a coating peels

We have no data on why the coating on your sample would peel. What can be said: data sheets for coated material include a coating adhesion test, ASTM D751 in the example we read, and for PU a hydrolysis test. If a supplier holds neither report, ask why. A written result lets you compare, while the word “durable” does not.

When the material is neither PU nor PVC

Other sheet materials exist. According to pages read on 22 Oct 2026, Malai says its material is bacterial cellulose from coconut water and lists no thickness or test data, and Desserto says its material is cactus-based, with its BIO+ line carrying a USDA label of 65% biobased. A partner page of MoEa says GrapeSkin carries a 45% water-based PU coating on recycled fabric. So some “alternative” materials still use PU. The percentages are not equivalent across makers, and this is not a ranking.

Kora, one of the producers discussed on this site, is researching a sheet from coconut and has published no test data or layer structure. We cannot place it on the PU side or the PVC side. See the Kora material status page.

Naming the material on a label

Write “PU” or “PVC” on a label only when the supplier states it in writing, with the part it covers. Do not carry other words from a note to a label without proof. The safe claims guide covers this, and the label claim check sheet helps you draft questions. For the term vegan leather, read what is vegan leather.

Sources and limits

Read on 22 Oct 2026: the Mitchell Faux Leathers article on faux leather specifications and testing (a US trader, 2017, upholstery references), plus the Malai, Desserto and MoEa pages above. The limits: it is one trader’s article, not a standard, and its figures are not the result of any one product. We did not read a full PU or PVC data sheet with test values.
