Ko te nuinga o te umanga kai e whakamahi ana i ngā takai kirihou BOPP. He ngāwari te tā, te pani me te whakakikorua i ngā putea BOPP, ā, he pai mō te tākai i ngā hua pēnei i ngā hua hou, ngā mea reka me ngā kai mātao. Haunga te BOPP, ka whakamahia hoki ngā putea OPP me PP mō te tākai. Ko te polypropylene he polymer noa i roto i ngā mea e toru e whakamahia ana mō te hanga i ngā putea.
Ko te OPP he whakarāpopototanga mō te Oriented Polypropylene, ko te BOPP he whakarāpopototanga mō te Biaxially Oriented Polypropylene, ā, ko te PP he whakarāpopototanga mō te Polypropylene. He rerekē te momo hanga o ēnei mea e toru. Ko te Polypropylene, e mōhiotia ana ko te polypropene, he polymer haurua-kiriata thermoplastic. He pakari, he kaha, ā, he ātete ki te pānga. He mea hanga ngā putea tū, ngā putea waha me ngā putea ziplock mai i te polypropylene.
He tino uaua ki te wehewehe i waenga i ngā kirihou OPP, BOPP me PP i te tīmatanga. Ka taea te rongo i te rerekētanga mā te pā atu, nā te mea he ngohengohe te PP, engari he pakarukaru te OPP. He mea nui kia mārama ki te whakamahinga o ngā putea OPP, PP me BOPP i roto i ngā taonga o te ao tūturu hei wehewehe i a rātou. Ko tePPka whakamahia ngā putea polypropene hei putea kore-whatu. Ka tukatukahia kia mimiti ai te makuku, te wai rānei.
Ko ngā nāpi, ngā tauera horoi me ngā tātari hau me ētahi atu he hua PP noa iho. Ka whakamahia hoki he rauemi rite mō te hanga kākahu wera nā te mea he ārai pāmahana. He mārama te tae o ngā putea OPP, ā, he kaha te kume. He ātete ki ngā pāmahana teitei engari ka miro mena ka whakamahia. Ka hangaia ngā rīpene piri mārama mā te whakamahi i te tauira kotahi.
He uaua ki te haehae, ā, e whakamahia ana ngā putea OPP hei tākai i te hiako me ngā kākahu me ētahi atu. He putea polyethylene mārama ngā putea BOPP. Mā te aronga rua-tuaka ka mārama te āhua, ā, he pai mō te waitohu mā te tā ki te mata. Ka whakamahia ngā putea BOPP mō ngā tākai hokohoko. Mā te aronga rua-tuaka ka kaha ake, ā, ka taea e rātou te kawe i ngā kawenga taumaha.
He ātete wai ēnei putea.
Ka tiakina ngā hua o roto i aua mea mai i te makuku mō te wā roa. Koinei te whiringa tuatahi i roto i te umanga takai kakahu. He ātete ngā putea PP, OPP me te BOPP ki te waikawa, te kawakore me ngā whakarewa waro. Koinei te take e whakamahia ai ēnei i roto i te umanga takai, ina kore e taea te karo i te rokiroki me te kawe i raro i te huringa o te hau. Ka peia e rātou te hua mai i te makuku me te puehu pērā i ngā kiriata piri.
Ka taea te hangarua, ā, he iti ake te waro e puta mai ana i te hangahanga. He pai hoki ngā putea PP, BOPP me OPP mai i te tirohanga taiao. He kaihanga putea BOPP a Rishi FIBC, ā, e tuku ana i ēnei i ngā utu mākete e taea ai te utu.
