Method for producing semicrystalline polylactic acid articles |
| 摘要 |
Amorphous sheets of PLA resins are thermoformed by heating the sheets until they become semicrystalline, and then forming the sheets on a relatively cold mold. Semicrystalline formed articles having improved heat resistance are made by the process.
