Kuyesetsa kwa R&D Kupangitsa Kupaka kukhala kokhazikika, kosavuta komanso kogwira ntchito.
Kuchokera pakutentha kwa dziko, gulu lathu la R&D likuyang'ana kwambiri mtundu umodzi wa zida zomwe zitha kubwezeredwanso.
Mmodzi wa msonkhano wathu ndi polyethylene Film Kuwomba, ife kusintha chilinganizo chimene chingakwaniritse zosowa mphamvu mkulu, izo zikhoza kunyamula mankhwala 0.5-10KG. Ndi yabwino kwa Mpunga, zinyalala zamphaka, zokhwasula-khwasula, mtedza ndi zinthu zina zopakira.
Mapangidwe azinthu zamtunduwu ndi BOPE/PE, makulidwe ake amatha kuchokera ku 80micron mpaka 190micron.
Ntchito yachiwiri, yomwe tikuchita ndi yogwira ntchito, pa thumba lina lolemera timawonjezera chogwirira chakunja cha thumba la pansi, ndilosavuta kunyamula. Chiwonetsero chabwino chazopaka zolemera zapakatikati.
Ntchito yachitatu, tikupanga zotchinga zazikulu zomwe ndi zabwino kunyamula chimanga chotsekemera, masamba opangidwa kale, ndi masamba onse amchere. The OTR(Oxygen transmission rate) ndi WVTR(Water vapor transmission rate) ndi pansi pa 0.5g/(m². 24h) ndi 0.5g/(m².24h.0.1Mpa). Phukusi lotchinga lalitali lidzabweretsa moyo wautali wa alumali, sungani chakudya mumtundu watsopano, komanso zabwino kuwonetsedwa pashelufu.
