Ukubhalwa okuvumelanayo yikho okwenza uku-oda okuphindayo kubikezeleke esikhundleni sokuba yingozi.

Uma ufuna umthombo wempahla eluhlaza yepulasitiki ye-LDPE yokwenza ifilimu, ukubumba, ukukhipha, noma ukukhiqiza ikhebula, indlela esheshayo ukuya phambili ingxoxo yezobuchwepheshe eqondile. Yabelana ngohlelo lwakho lokusebenza, i-melt index nomthamo wokuminyana okuhlosiwe, umthamo wanyanga zonke, kanye nechweba lendawo oya kulo, futhi ithimu izophendula ngezincomo zezinga, amasampula, kanye nentengo. Abathengi abaqhathanisa abahlinzeki kufanele babuze mayelana nokulandelelwa kweqoqo, imibhalo yokuhlola, kanye nezikhathi zokuhola, ngoba lezo zimininingwane zihlukanisa umlingani othembekile kumthengisi wokuhweba nje. I-Dongguan Hanxin Plastic Technology Co., Ltd. yakhelwe phezu kwekhwalithi engaguquguquki, intengo encintisanayo, ama-MOQ aguquguqukayo, kanye namandla okuhlinzeka isikhathi eside. Noma ngabe udinga izinga lefilimu elijwayelekile, ukufanisa umbala okwezifiso, noma ingxubevange ye-virgin ne-recycled, umgomo uyafana: impahla esebenza ngendlela efanayo njalo lapho ingena emugqeni wakho. Xhumana namuhla ukuze ucele isilinganiso sentengo futhi uthathe isinyathelo esilandelayo sokuya ebudlelwaneni bokuhlinzeka nge-LDPE obuthembekile.
