Polylactic acid (PLA) ili ndi mphamvu yolimba komanso yolimba kwambiri. PLA imatha kupangidwanso pogwiritsa ntchito njira zosiyanasiyana zochizira, monga kusungunula extrusion molding, jekeseni, kupukutira filimu, kupukutira thovu ndi kupukutira vacuum. Ili ndi mawonekedwe ofanana ndi ma polima omwe amagwiritsidwa ntchito kwambiri. Kuphatikiza apo, ilinso ndi magwiridwe ofanana osindikizira monga mafilimu achikhalidwe. Mwanjira imeneyi, polylactic acid imatha kupangidwa kukhala zinthu zosiyanasiyana zogwiritsidwa ntchito malinga ndi zosowa za mafakitale osiyanasiyana.
Filimu ya lactic acid (PLA) ili ndi mpweya wabwino wolowa, mpweya wolowa komanso mpweya woipa. Ilinso ndi makhalidwe olekanitsa fungo. Mavairasi ndi nkhungu n'zosavuta kumamatira pamwamba pa pulasitiki yowola, kotero pali kukayikira za chitetezo ndi ukhondo. Komabe, polylactic acid ndiye pulasitiki yokhayo yowola yomwe ili ndi mphamvu zabwino kwambiri zotsutsana ndi mabakiteriya ndi bowa.
Poyatsa polylactic acid (PLA), mphamvu yake yoyaka imakhala yofanana ndi ya pepala loyaka, lomwe ndi theka la mapulasitiki achikhalidwe oyaka (monga polyethylene), ndipo kuyatsa kwa PLA sikudzatulutsa mpweya woopsa monga nitrides ndi sulfides. Thupi la munthu lilinso ndi lactic acid mu mawonekedwe a monomer, zomwe zimasonyeza chitetezo cha chinthu ichi chowonongeka.
