Ko te muka polyethylene taumaha-rahi rawa te rauemi ātete-matū mama rawa atu o te ao, he nui te ōwehenga kaha-ki-te-taumaha, he teitei te modulus. Nā te kaha mimiti, ka taea te whakaiti i te kino kore-whakauru. Haunga, ka taea e te papanga UD te mimiti i te ru o te matā me te aukati i ngā wahi matā pakaru hei whakakore i te whara tuturu me te ārai i ngā whara tuarua. Nō reira, koinei te rauemi hiato ātete-matū ngohengohe tino matatau.

He maha ngā painga o te hangarau ahurei o tā mātou papanga, arā, he tino pai te mahi ā-poro, he kounga pono, he whakamarie te mau, he mama, he ārai i te hihi UV, he kaha te pakari, he pai te āhua o te ngāwari, he nui te mimiti pūngao. He tino pai te tiaki i te waikura, te ātete ki te makuku, te pumau o te wera me te ātete ki ngā taiao whakaeke. Whakamahinga: He koti pukupuku tinana, he pereti pukupuku mārō, he whakangungu ātete pahū, he paraikete pehi pahūtanga poma, he tiaki ātete poro me te pānga, he taputapu tiaki tūmatanui pēnei i te hanga pukupuku o ngā waka, tāke, waka rererangi, kaipuke moana, anga tiaki radar me te pere, me ētahi atu.
