Ca pob zaub hauv qab cov khoom noj yog ua los ntawm cov khoom siv yas ldpe, feem ntau yog cov khoom siv sib txawv ntawm cov khoom siv, kev ua lag luam hauv hnab, cua sov}}}}}
1.} Cov Khoom Xaiv (LDPE)
Tsawg-Ntawj Polyethylene (LDPE): zoo hloov, thiab cov khoom siv tau khoom noj (xws li FDA ntawv pov thawj).
Thickness tswj: feem ntau {40-120 μm, nws yuav tsum tau muab extruded tusyees kom tsis txhob cuam tshuam nrog tus nqi .
{{0 {}} bag ua txheej txheem (tiaj lub hauv qab hnab ua ke)
Cov txheej txheem tseem ceeb ntawm cov hnab hauv qab yog hauv qab kub sealing + sab folding ua kom nws sawv ntsug. Cov kauj ruam tshwj xeeb suav nrog:
(1) Zaj duab xis Unwinding & Luam Ntawv (Yws)
Yog tias yuav tsum tau luam tawm (xws li hom logo hom), flexographic machines tau siv, tab sis cov luam ntawv LDPE xav tau kev pab tshwjxeeb (corona kev kho mob txhim kho number casis).
(2) Cov kauj vab hauv qab (kauj ruam tseem ceeb)
Thaum tshav kub tuav txoj kev: Siv cov kev sib tsoo cua sov kom ua rau daim ntawv tiaj tus qauv .
Thawj zaug folding zaj duab xis nyob rau hauv ib nrab thiab kub muab lub ntsaws ob sab (los ua lub raj) .
Hauv qab yog nias los ntawm kev kub sib tsoo riam rau daim ntawv "m-puab" lossis "lub hnab ntawv-style" .
Kev tswj qhov kub thiab txias: Cov kub sib khi ntsuas kub ntawm LDPE feem ntau 110-150℃ua kom tsis txhob yaj los yog xoob ntsaws .
(3) Sab Folding (Gusset Kho, yeem)
Yog tias koj xav tau ntxiv rau lub peev xwm, koj tuaj yeem ua kom cov khoom sib xyaw ua ke (Side Gussets) ntawm ob tog
(4) lub qhov ncauj tiaj tus nqi (tsis muaj kev sib khi)
Lub hnab ntim lub qhov ncauj nyob twj ywm (tiaj tus qhov ncauj), thiab tom qab ntawd muab cov khoom siv sib khi los yog kaw los ntawm cov khoom siv sealing tom qab tus neeg siv khoom noj khoom haus.
3. Thaum tshav kub kub muab lub zog thiab kev xeem sealing
Thaum Tshav Kub Kub Lub Zuag Sij Hawm: Ua kom cov txiv ntoo hauv qab no (xws li kev sim nruj me me)} {{{1} .
4.} Kev tiv thaiv ib puag ncig thiab cov txheej txheem tshwj xeeb (yeem)
Cov neeg saib xyuas hluav taws xob tsis meej: Yog tias tus neeg yuav khoom tiv thaiv ib puag ncig, xws li D2W
Cov tshuaj tua kab mob: Siv rau Hmoov Hmoov Ntim kom tiv thaiv cov ntawv tshaj tawm zoo nkauj .
