Itandukaniro riri hagati y'udufuka duhagaze n'udufuka duto two hasi.

DQPACK kugira ngo ubasobanurire itandukaniro riri hagati y'udufuka duhagaze n'udufuka duto, mbere ya byose, reka dusobanukirwe imiterere y'ubwoko bubiri bw'udufuka.

Udupaki two guhagarara, mu by'ukuri, hari abantu benshi kuri interineti basobanurwa gutyo: ntushobora kwishingikiriza ku bintu byo hanze by'aho ushyigikira, hamwe na two ubwatwo dushobora guhagarara ku mifuka yo gupakira, ibi byitwa udupaki two guhagarara. Mu by'ukuri, ibisobanuro nk'ibi biroroshye cyane kwitiranya udupaki two guhagarara n'imifuka umunani yo ku ruhande. Niba hasi hari aho upfundika n'impande ebyiri, impande zo hejuru n'izo hepfo akenshi ziba zifite impande zipfunyitse, nyuma yuko hasi hafunguwe, agapaki gashobora guhagarara, kitwa udupaki two guhagarara. Imiterere isanzwe yo gupakira: NY/PE, PET/NV/PE, PET/NY/AL/PE, PET/VMPET/PE, impapuro zo gushushanya.

Imifuka yo hasi igororotse, imifuka yo hasi igororotse ishobora no kwitwa imifuka yo hasi ya Qual Seal, hasi yayo igororotse, n'impande umunani zipfunyitse, bityo byitwa imifuka umunani ipfunyitse ku ruhande. Hari impande enye hepfo hamwe n'impande ebyiri ku mpande zo hasi, impande zose hamwe umunani. Ipfunyitse ku mpande umunani ifite ubuso butanu bwo kwerekana: bumwe kuri buri ruhande rw'imbere n'inyuma, bumwe kuri buri ruhande rw'inyuma n'inyuma, hamwe n'ubundi hepfo. Ubushobozi bwo gupfunyika ni bwinshi mu buryo bwo gupfunyika: PET/AL/BOPA/PE, PET/AL/PE, BOPP/VMPET/PE, PET/VMPET/PE. Imifuka yo hasi igororotse nk'iyo ishobora gutwara amakuru menshi y'itangazamakuru n'itangazamakuru, bitewe n'ubushobozi bwo kwerekana neza ibiryo n'ikirango cyabyo imbere.

Itandukaniro riri hagati y'udukapu twometseho uduce duto n'udukapu twometseho uduce duto, nyuma y'ibisobanuro byavuzwe haruguru, mu by'ukuri, itandukaniro riri hagati yatwo cyangwa rigaragara cyane. Hasi y'udukapu twometseho uduce ntabwo turinganiye, mu gihe hasi y'agapapuro k'impande umunani aringaniye; hari kandi umubare wose w'inkombe zatwo ntabwo ari umwe, udukapu twometseho uduce duto dufite bine, udukapu twometseho uduce duto dufite umunani; byongeye kandi, umubare wose w'ubuso bwo kwerekana ntabwo ari umwe, udukapu twometseho uduce dushobora kuba tubiri gusa, mu gihe udukapu twometseho uduce duto nta gushidikanya ko dufite dutanu. Muri rusange, udukapu twometseho uduce duto kurusha udukapu twometseho uduce duto, dufite imiterere myiza, duhamye, ariko dushobora no gucapa ibintu byinshi; ariko igiciro kirahenze, kuko mu bipimo bya tekiniki nabyo biri hejuru.

DQPACK imaze imyaka irenga 30 ikora imifuka yo gupfunyika, ikoresheje ikoranabuhanga rigezweho kandi ikora neza. DQ Pack, niyo ibaha serivisi nziza zo gupfunyika.
