What are the main price differences between wicker pattern celluloid film and regular celluloid film? Is the texture process more expensive, or is there a difference in the raw materials used?

The price difference primarily reflects the cost of the texturing process.
Wicker brushed celluloid film requires additional processes like embossing and etching to create a three-dimensional texture. These specialized molds and processing steps increase production time and cost. Standard celluloid film, on the other hand, is mostly flat and basic, requiring simple processing.
The difference in raw materials has little impact on the price, as the base materials for both are essentially the same.
