Dupont new thermal plastic packaging materials innovation disposable tableware

A consortium of Earth Shell and DuPont Packaging and Industrial Polymers is currently working on the sandwich packaging market. They have developed a new type of biodegradable thermoplastic packaging material that can be used in existing blown films and Film production on the equipment.

This new material has excellent foldability, flexibility, ease of printing, and protection against moisture. It is less expensive than EPS (Expanded Polystyrene) and has a better texture and feel. Compared with paper products, it is lighter and has better heat insulation effect. It has been in hotels in several cities and eight countries. They have been tested and are expected to replace other paper products for disposable food packaging products. However, deep molding of this composite material is a more difficult problem than other hard materials. In the vacuum forming process of the biodegradable film lining, it is necessary to maintain the same wall thickness to avoid wrinkling.

At the same time, the rigid sheet made by Earth Shell is being tested to see if it can replace the application of packaging board in the food and non-food industry. Others, such as the use of synthetic materials through the injection molding process to make disposable knives, forks, Work on spoons and coffee blenders is also in progress.
