No, polyvinyl chloride acetate (PVC acetate) does not exist because it is chemically impossible.

Polyvinyl chloride (PVC) is a polymer made from the monomer vinyl chloride (CH₂=CHCl).
Polyvinyl acetate (PVA) is a polymer made from the monomer vinyl acetate (CH₂=CHOCOCH₃).

These two polymers have completely different chemical structures and properties. They cannot combine into a single polymer called "polyvinyl chloride acetate." However, there are blends or composites where PVC and PVA are used together, but this is a physical mixture, not a chemical compound.

PVA (Polyvinyl Acetate) is a material we know as glue, often used for wood, paper, and other materials.

As for PVC (Polyvinyl Chloride), it is used as a plastic and can be a component of a mixture containing cellulose acetate.

Cellulose acetate is a biopolymer derived from cellulose, often added to PVC mixtures to improve properties such as flexibility, transparency, and mechanical strength. As a result, such a mixture can contain more cellulose acetate than PVC itself.

The primary substance in the mixture determines its properties, even if the polymer matrix is PVC.

Cellulose acetate in its pure form is transparent and brittle, and it cannot be used on its own for playing cards.

Therefore, it can reasonably be stated (as far as possible without performing a chemical analysis) that these are "acetate cards."

Thanks for your very informative insights!

The only PVA i know is Polyvinyl-alcohol = water soluble.
Definately nothing that should be in plastic playing cards ; )

As the resident animation nerd, the transparent sheets that animated characters were drawn on (to allow the non-moving background to be seen through) were called "cels", after the cellulose acetate* they were made from.

Early in the game, these were expensive, so the inked and painted drawings on them were washed off so the cels could be re-used.


Odds are, your favorite single frame from a Bugs Bunny or Tom and Jerry cartoon existed long enough to be photographed and checked before being washed into the Burbank sewers so it could be re-used incredibly high.


* the predecessor was cellulose nitrate which was quite flammable. This was also used for film stock and was partly responsible for the loss of many early movies and films when that caught fire, destroying the media.

Hahaa - i don‘t want to stress you, but thanks!

OK, finally dug out my Club Angel deck. Some observations -

1. The packaging does not say Acetate (nor PVC) for that matter.
2. The cards show zero signs of bowing considering its age (easily 6+ years old)
3. Texturing is smooth on the card back with a very visible (faux?) linen type finish on the face, similar in looks to an OG Bicycle card.

On this forum, such posts without additional photos are a crime.

They used old movies for explosive special effects for a while. Simply drill a hole in the tin holding the movie, insert a fuse, and instantly you have a land mine

Stuff with chlorine in it - kills you
Stuff with nitrogen in it - blows up great

If cards could spontaneously combust or decks explode at the table, it would give new meaning and gravitas for bomb pots.

It would be like opening canned biscuits at high altitudes. You flinch the entire time because you don’t know when it’s going to literally explode.

We learned not to buy them at low altitudes and then bring them here. They usually explode in the car on the way up.
