Pogwiritsa ntchito matumba a tiyi popanga tiyi, tiyi yonse imayikidwa mkati ndipo tiyi yonse imachotsedwa, zomwe zimapewa vuto lolowa mkamwa mwa tiyi, komanso zimasunga nthawi yotsuka tiyi, makamaka vuto lotsuka mkamwa, zomwe zimakhala zosavuta komanso zopulumutsa ntchito. Matumba wamba a tiyi nthawi zambiri amapangidwa ndi nayiloni, yomwe nthawi zambiri imatulutsa fungo; MATUNGULU A TCHIPAKI CHOKHALA CHA CHIMADZI CHOPAKIDWA amachokera ku starch ya zomera, yomwe ndi yotetezeka, yaukhondo, komanso yopanda fungo.
Matumba a tiyi osalukidwa omwe amapezeka pamsika nthawi zambiri amapangidwa ndi zinthu za polypropylene (pp material), zomwe zimakhala ndi mphamvu yolowera komanso sizimatentha. Komabe, chifukwa chakuti sizipangidwa ndi zinthu zachilengedwe, nsalu zina zosalukidwa zimakhala ndi zinthu zina zoopsa zikapangidwa, zomwe zimatulutsidwa zikaphikidwa m'madzi otentha. Si thumba la tiyi labwino kwambiri.
Zinthu za PLA polylactic acid sizodziwika kwa aliyense. Ndi mtundu watsopano wa zinthu zopangidwa ndi chimanga, zomwe sizivulaza thupi la munthu komanso zimawonongeka. "PLA" imapangidwa makamaka ndi chimanga, tirigu, chinangwa ndi zina monga zinthu zopangira, zomwe zimapangidwa ndi polymer kudzera mu kuwiritsa ndi kusintha. Sizimayambitsa poizoni komanso siziwononga chilengedwe ndipo zimatha kuwonongeka mwachilengedwe. Pogwiritsa ntchito tizilombo toyambitsa matenda m'nthaka ndi m'madzi a m'nyanja, ulusi wa chimanga ukhoza kuwola kukhala carbon dioxide ndi madzi, ndipo sudzadetsa chilengedwe cha dziko lapansi utatayidwa. Ndi chinthu chodyedwa komanso chowonongeka. Matumba a tiyi a ulusi wa chimanga ndi otetezeka komanso osavulaza thupi la munthu ndipo ndi a mtundu wodyedwa.
OKPACKAGING imagwiritsa ntchito ulusi wa chimanga wa PLA popanga matumba a tiyi. Thumba la tiyi wa chimanga la m'chigwachi, kuyambira pa chingwe chokokera mpaka pa thupi la thumba, limapangidwa kwathunthu ndi ulusi wa chimanga wa PLA, womwe ndi wotetezeka komanso wathanzi. Zinthuzo zimasinthidwanso, kuyambira ulusi waufupi mpaka ulusi wautali, womwe suvuta kusweka. Ngakhale utaphikidwa ndi madzi otentha ndikuwiritsa mobwerezabwereza, palibe chifukwa chodera nkhawa za kupanga zinthu zovulaza, ndipo umalandira mphamvu zotsutsana ndi mabakiteriya komanso zoyambitsa bowa za zinthu za PLA, zomwe zimapangitsa kuti zikhale zosavuta kusunga nthawi yamtendere. Ndipo chifukwa cha makhalidwe owonongeka a PLA, chitukuko cha nthawi yophatikizana, poyankha mfundo zoyenera za boma zoteteza chilengedwe, kuti tipewe kuipitsidwa kwa chilengedwe.
