No. Currently, some of our products are made from biodegradable polypropylene and others are made from plastic films that are made from corn. Because these materials offer different benefits, we believe it is important to offer a choice and to help you make the choice that best fits your project requirements. More information on the materials we use are available in our materials wiki and on the product pages. If you have specific concerns that are not answered on this web site, please don't hesitate to contact us.
