BOPLA e na le melemo e meraro ts'ebelisong ea 'maraka.
Taba ea pele, BOPLA ke filimi e tšepisang ka ho fetesisa e thehiloeng linthong tse phelang 'marakeng.Ka lebaka la litšobotsi tsa thepa le machinability ea PLA, BOPLA e na le mehato e fokolang ea tlhahiso le bothata bo fokolang ba ho sebetsa, 'me e na le melemo ea ho thibela metsi le ho hatisoa ha filimi ea setso ea polymer, e etsang hore e be le tebello e kholo tšimong ea kopo ea filimi e tšesaane.
Ea bobeli, BOPLA e na le litšobotsi tse laolehang tsa ho senyeha.Tlas'a maemo a tloaelehileng a polokelo, BOPLA e ka boloka ts'ebetso e ntle ho netefatsa bophelo ba sethala sa lihlahisoa le ho qoba ho khutsufatsa sethala sa lihlahisoa tsa lihlahisoa ka lebaka la lebelo le feteletseng la ho senyeha.Tlas'a maemo a manyolo, BOPLA e ka finyella botenya ba filimi e mosesaane tlas'a thepa e tšoanang ea mochine, e le hore e ka senyeha ka potlako tikolohong ea manyolo.
Ea boraro, BOPLA e fihlela litlhoko tsa lipalangoang tse tloaelehileng tsa polokelo ea thepa le thepa, 'me e na le motheo oa ts'ebeliso ea indasteri.Tekong e potlakileng ea botsofali ea BOPLA (FIG.2), matla a ho tiea a senyeha feela ka 4.5% ka mor'a selemo se le seng le 5.2% ka mor'a lilemo tse peli.Matla a ho tiisa mocheso a fokotsa 12.8% ka mor'a selemo se le seng, se finyellang litlhoko tsa ts'ebetso ea ho tiisa mocheso.Litekong tsa leoatle tsa BOPLA (Xiamen-Antwerp, FIG. 3), ho ne ho se na phetoho e kholo ea thepa ea lifilimi le ponahalo.
