In week two, the previous idea of using strictly starch-based polymers for the garbage bag polymer film was reconsidered. A decision was made to develop a composite material made of PLA and food starch for a more durable product. This would result in a stronger bag, and the combination of the two materials would help to alleviate several issues of concern, such as the lack of durability of starch polymers and high cost of PLA alone. Going into week three, a reasonable time table was developed, and the specific materials necessary to further pursue the project were considered. A design proposal was developed based on previous research and detailed project plans.
Below is a link to the Design Proposal for the project:
