DI Acetate

BIO-based Film

Our optimont® CDA film is a wood fiber cellulose film. This film is made from renewable resources and convinces with its ultra-clear transparency of 0.6% (haze), which is excellent for a "bio-film". Our film is certified for composting according to DIN EN :13432:2000-12 and ASTM D6400 and is suitable for own composting up to a thickness of 75my. The complete composting process takes about 14 weeks. Due to the excellent transmission rate for moisture, good antifog properties and good transparency for UV light (increased UV resistance), the film is suitable as a bio-based alternative for other plastics such as polypropylene, PVC or polyester.

The application range of this film extends from window applications for packaging to lamination and industrial applications.

Production of our optimont® CDA films:

Cast cellulose di-acetate film is produced by dissolving di-acetate flakes (wood fibers) in acetone to form a spinning solution (polymer solution). Various additives are combined to improve the processability of the spinning solution and the performance of the resulting film. These include plasticizers, antiblocking agents, release agents, colorants, etc. The spinning solution is filtered, deaerated and poured through a nozzle (the box) onto a continuously moving, highly polished stainless steel belt. Drying takes place both in the belt tunnel and in a drying cabin in a counterflow of hot air. The acetone in the solvent laden air is recovered and reused. The measuring device is controlled by the box gap, the belt speed and the dosing pump rate. The film is wound and then cut according to customer specifications, with residual pieces being recycled.
