Abstract
The present disclosure relates to food safe water resistant articles, which include recyclable cellulosic utensils having a food safe water resistant material. In addition, food safe water resistant composition used for preparing food safe water resistant articles as well as use of the same are also disclosed.
Claims18
A food safe article comprising:
- a paper substrate comprising a plurality of cellulose fibers;
- and
- a food safe water resistant material comprising an organo-silicon polymer, wherein the food safe water resistant material impregnantly covers at least a portion of a surface of the paper substrate thereby imparting a wet strength of at least 2,000 Newtons to the paper substrate.
Use of a food safe article for consuming, serving, transporting, storing, or disposing of food wherein the food safe article comprises:
- a paper substrate comprising a plurality of cellulose fibers;
- and
- a food safe water resistant material comprising an organo-silicon polymer, wherein the food safe water resistant material impregnantly covering at least a portion of a surface of the paper substrate thereby imparting a wet strength of at least 2,000 Newtons to the paper substrate.
A method for preparing a food safe article, the method comprising:
- i. providing a paper article comprising a plurality of cellulose fibers;
- and
- ii. contacting the article with a food safe water resistant composition thereby forming a food safe water resistant material comprising an organo-silicon polymer, wherein the food safe water resistant material impregnantly covering at least a portion of a surface of the paper article thereby imparting a wet strength of at least 2,000 Newtons to the paper article.
