A biopolymer composition, a preparation method for the same, and a bioplastic using the same, the biopolymer composition comprising at least 83.5 weight % of a copolymer resin of lactic acid (LA) and 3-hydroxypropionate (3HP), an antioxidant, and a lubricant, and the composition having an elongation percentage of at least 90% but not greater than 500%.

Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.

Insulated shippers having vacuum insulated panels (VIPs) adhered to PLA-based bead foam are provided. The insulated shippers advantageously extend the effective thermal performance of the VIPs and enable the formation of thermal shippers capable of at least 8 days, and in some cases more than 14 days, of effective thermal performance, enabling the formation of thermal shippers capable of delivering thermally sensitive goods to more remote destinations without substantially increasing the cost of the shipper.
