According to Celanese, cellulose diacetate is gaining popularity as an alternative to oil-based plastics. The company's Clarifoil thermoform film is produced from cellulose obtained sustainably from managed forestry plantations and without genetic modification, and therefore scores right across the board in terms of environmental friendliness. It also offers "outstanding clarity" and good properties for thermoforming.
"Clarifoil film is biodegradable and, up to a certain thickness, can even be composted together with domestic garden waste," says Katharina Wiesauer, market development manager for the Clarifoil product line. "The positive environmental properties do not compromise ease of use, quality and cost of good design."
The high thermal stability of the Clarifoil thermoform film means that the softening temperature is 120degC. "Clarifoil thermoform film excels over other bioplastics in this respect," says Wiesauer. "This makes it especially attractive for packaging hot foods and beverages. Additionally, this environmentally friendly film is ideal for the storage and transport of goods in hot climates."
Clarifoil thermoform film is approved for direct food contact and is also suitable for packaging cosmetics, upscale electronics devices and other luxury goods.
