Abstract
Official abstract text for this publication.
A multi-layer film having a first film layer being at least partially formed from a polymer (A) and a polymer (B) and a second film layer being at least partially formed from the polymer (A), the polymer (B), a polymer (C), and optionally an opacifying agent, wherein at least one of the polymer (A), the polymer (B) and the polymer (C) is synthetic and is at least partially derived from a renewable resource such that the multi-layer film has a bio-based content of about 10% to about 100% using ASTM D6866-10, method B. Methods of forming multi-layer films are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, of forming a multi-layer film, comprising: a. providing a renewable resource selected from the group consisting of plants, animals, fish, bacteria, fungi, and forestry products; b. deriving a monomer from the renewable resource and polymerizing the monomer to form a synthetic polymer; c. forming at least one of polymer (A), polymer (B) and polymer (C) from the synthetic polymer; d. processing a first film layer having an upper surface and a l…
