Consumers and companies alike are interested in sustainable and recyclable packaging made from renewable materials, such as wood. Using cellulose and fatty acids — two completely renewable substances — VTT has developed Thermocell, and development work is currently underway.
Thermocell is a 100% biobased thermoplastic that, like conventional plastic, can be refined into packaging films. Food and beverage companies can use existing plastic converting equipment to apply heat and mould the material: the process steps are straightforward and can be up-scaled with business-as-usual engineering.
