摘要 |
<p>The present invention is directed to a method of producing a themoformable composite by crosslinking PHA and PLA together in the presence of an additive to produce PHA and PLA blend and resins having: (a) a Ts value of up to about 18O0C; and (b) a heat distortion index of up to about 16O0C. The themoformable composite is used to make a food or beverage cup, lid, cutlery item, foodservice item, molded tray, or food storage container. The thermoformable composite comprises from about 5% to about 95% by weight of polylactic acid (PLA), from about 5% to about 95% by weight polyhydroxyalkanoate (PHA) polymer, and from about 0.01% to about 60% additives wherein the PLA and PHAs being crosslink together by intermolecular means to enhance performance and processability</p> |
