| Résumé : |
Vast quantities of food are thrown away every year. Modern plastic packaging keeps food fresh and preserves its flavor for longer, so it reduces the amount of valuable produce that is wasted. At the same time, politicians are calling for more environmentally friendly packaging. Kuraray provides key barrier materials for this, including biodegradable polymers that are impermeable to gas. |
| Note de contenu : |
- Protection against oxidation
- Environment-friendly printable barrier layers
- Biodegradable packaging with a gas barrier
- Fig. 1 : A layer of only four micrometers of Eval barrier copolymer prevents impurities such as mineral oil from recycled cartons contaminating food
- Fig. 2 : Softpack’s coffee packaging is biodegradable and impermeable to gas. The biodegradable barrier polymer Plantic is used in this packaging to keep out oxygen and make sure the coffee.
- Table 1 : Oxygen permeability of a PE film coated with Exceval and metalized, analyzed at 23°C and 65% relative humidity in100% oxygen. The barrier layer shows good properties even after 20-fold torsion of the film. |
