The invention relates to a molded part made of completely biodegradable starch foamed material to be used for protecting transported articles and to a method for its preparation, wherein the starch foamed material is expanded to form starch foam profiled sections which are selfadhesive when moisture is applied and can be processed individually or so as to form single or multi-layer foam panels.

Why it's free to use
- Filed September 5, 1995 and granted December 3, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 5, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 5, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
