Mokhoa oa ho etsa lifilimi o lokela ho ela hloko lintlha tse latelang:
1. Tekanyo ea thepa e tala: ho ea ka litlhoko tse sa tšoaneng tsa mekotla ea PE, ho lokisoa ha likarolo tse fapaneng tsa thepa e tala. Mohlala: anti-static, anti-rust, ho fokotsa, conductivity ea motlakase, biodegradation le litlhoko tse ling, eketsa mefuta e fapaneng ea li-additives mohlala: ho sebelisa mebala e khubelu, e ntšo, e mebala le mebala e meng, eketsa mefuta e fapaneng ea li-caps tsa mebala. Ho latela pepeneneng, ho tiea, matla a ho tabola, ho ntšoa ha vacuum le litlhoko tse ling, ho nkela mefuta e fapaneng ea mefuta kapa mefuta ea thepa ea PE. Ka mohlala: ho ea ka litlhoko tse khethehileng, hatisa litlhoko tsa ponaletso e phahameng, ho taboha ho matla, ho buleha hantle, e le ho fetola karolo ea lihlahisoa tse tala.
2.mokhoa oa ho phunya khatiso ea filimi, tlhokahalo ea ts'ebetso ea elektronike, ka nako ena ho ela hloko matla a ts'ebetso ea elektronike, ho etsa bonnete ba hore PE drum material processing electronic processing strength (DAYIN) e lekaneng ho etsa bonnete ba ho khomarela enke.
3.ka mokhoa oa ho phunya filimi, ho ea ka litlhoko tse khethehileng tsa filimi, ho bula ha 'ngoe, ho bula habeli, ho phutha, ho senya khatello, ho khabisa, ho atolosa le mesebetsi e meng.

2. Letlapa la khatiso: ho ea ka litlhoko tse ntle tsa litaba tsa khatiso, khatiso ea gravure (copper plate) le flexography (offset) khatiso e sebelisoa. Mekhoa ena e 'meli e fapaneng ea khatiso.
3. Ho ea ka ho rarahana ha litaba tsa khatiso le ho rarahana ha mebala, khetha mokhoa oa khatiso: khatiso ea monochrome, khatiso ea monochrome ka mahlakoreng a mabeli, khatiso ea mebala e le 'ngoe, khatiso ea mebala e mabeli.
4. Ho ea ka litlhoko tse khethehileng tsa mekhoa ea khatiso, ho ea ka litšoaneleho tsa ho feto-fetoha ha mebala, li-anti-counterfeiting, conductivity ea motlakase, li-adhesives joalo-joalo, khetha enke e fapaneng kapa li-additives.
