Buku Lophunzitsira la GC1 Paperboard Complete Sourcing Guide: Mafotokozedwe, Kuyerekeza, ndi Mndandanda Wogulira
Bolodi la mapepala la GC1 ndi bolodi loyera lopindika kumbuyo (FBB) yofotokozedwa motsatira DIN 19303, imodzi mwa mitundu yodziwika bwino kwambiri ya makatoni padziko lonse lapansi. Kapangidwe kake ka magawo atatu — pulp ya mankhwala yophimbidwa pamwamba, pulp ya chemi-mechanical (CTMP) pakati, ndi pulp ya mankhwala yophimbidwa kapena yosaphimbidwa kumbuyo — imayesa mtundu wa zosindikizidwa, kuuma, ndi mtengo wake.
GC1 ndi yosiyana ndi kumbuyo kotuwa Bodi la Duplex chifukwa mbali yake yakumbuyo imaoneka yoyera kapena yopepuka. Izi zimapangitsa GC1 kukhala chisankho chomwe chimakondedwa pamene pamwamba pa phukusili pakuwonekabe kwa ogula, monga m’zivundikiro zophimba pamwamba kapena mabokosi odulidwa pawindo.
Mtundu Wamba wa GC1 (Mitengo Yofotokozera)

Miyezo ndi yosonyeza. Zofunikira zenizeni pa COA iliyonse ya ogulitsa. Kulekerera makulidwe a ±4%, kulekerera kuuma kwa −15% pa ISO 534 ndi ISO 2493.
Zinthu za Paperjoy Pepala la GC1kuyambira 170 mpaka 400 gsm, yokhala ndi kapena yopanda PE coating, mu mipukutu yayikulu kapena mapepala odulidwa mwamakonda.
Zochitika Zinayi Zogwiritsira Ntchito ndi Momwe Mungasankhire Giredi Yoyenera ya GC1
Ma phukusi a Mankhwala (Mabokosi Opukutira Mankhwala)
Zofunikira pa kusindikiza: makamaka zolemba ndi mitundu yosavuta, kuyera kwambiri koma kopanda kunyezimira kwambiri.
Zoyenera: 210–250 gsm. PPS pamwamba ≤ 1.5 μm kuti mupewe kusokoneza zilembo pa kukula kwa zilembo zazing’ono.
Zodzoladzola & Ma phukusi Ogulitsa Apamwamba
Zofunikira pa kusindikiza: malo akuluakulu olimba, kupondaponda zojambulazo zotentha, kusindikiza.
Zoyenera: 270–350 gsm. Mphamvu ya pamwamba ≥ 1.2 m/s (liwiro lotola IGT) kuti zisawonongeke.
Mapaketi a Chakudya Chouma (Mabisiketi, Ma Confectionery, Mabokosi a Chakudya Champhatso)
Zofunikira zosindikizidwa: zithunzi zokongola, mtundu wodalirika.
Zoyenera: 230–300 gsm. Yang’anani FDA 21 CFR 176.170 kapena malire osamukira m’deralo ngati pakufunika kukhudzana mwachindunji ndi chakudya.
Dziwani: Mbali yakumbuyo ya GC1 ndi yoyera koma sinapangidwe kuti igwirizane ndi chakudya. Sinthani ku Bungwe la C1S Ivorykapena onjezerani chophimba cha PE kuti chakudya chigwirizane mbali ziwiri.
Kuyika Zinthu Zamagetsi ndi Zogulitsa
Zofunikira zosindikiza: varnish yamitundu yambiri + UV, gloss ≥ 50% pa 75°.
Zoyenera: 250–350 gsm. Yesani kaye kuchuluka kwa kuyamwa kwa UV pamalo ophimbidwa ndi mchere musanapange.
GC1 vs GC2 vs FBB vs C1S — Kuyerekeza Mbali ndi Mbali
| Kukula | GC1 | GC2 | FBB (Yopanda Chivundikiro) | Bungwe la C1S Ivory |
| Mtundu wakumbuyo | Choyera (chofiirira) | Kirimu/zachilengedwe (zamakina) | Zofanana ndi nkhope kapena zakuda | Choyera |
| Kuphimba | Chophimba chakutsogolo + chosankha chakumbuyo | Chokutidwa kutsogolo | Palibe kapena kuwala kwambiri | Chokutidwa ndi mchere cha mbali imodzi |
| Zambiri | Wapamwamba (CTMP core) | Pakatikati | Ulusi wapamwamba kwambiri (wosaphimbidwa) | Wapakati (zamkati mwa mankhwala) |
| Mtundu wosindikiza | Mbali zonse ziwiri zosindikizidwa, kutsogolo kwapamwamba | Zosindikiza zakutsogolo bwino, kumbuyo kuli kochepa | Yogwiritsidwa ntchito m’madzi/yosinthasintha yoyenera | Kutsogolo kwapamwamba, kumbuyo kopanda utoto |
| Mitengo yosiyanasiyana | Pakati | Pakati-pang’ono | Pakati | Pakati-mmwamba |
| Zabwino kwambiri pa | Mankhwala, zodzoladzola, chakudya chouma | Makatoni opindika amtengo wapatali | Makatoni osavuta, mathireyi | Ma phukusi apamwamba, ma Albums |
Buku Lotsogolera Zosankha:
– Mbali zonse ziwiri ziyenera kuwoneka zofanana → GC1 (ubwino wa kumbuyo koyera)
– Kulimba kwakukulu pa gramu iliyonse → FBB (yosaphimbidwa, yolemera kwambiri)
– Zosindikizidwa kutsogolo ndiye zofunika kwambiri, kumbuyo sikofunika → GC2 (mtengo wabwino kwambiri)
– Kuyera kwambiri komanso khalidwe lapamwamba la mbali ziwiri → C1S Ivory Board (yoyeretsedwa bwino)
– Imafunika kukana mafuta ndi mafuta → GC1 + PE coating (ikupezeka ku Paperjoy)
Mndandanda Wowunikira wa Mfundo Zisanu ndi Chimodzi kwa Ogula Mabungwe a GC1
Musanayike oda, tsimikizirani magawo asanu ndi limodzi awa ndi omwe akukupatsani:
- Kulekerera kwa Grammage
ISO imalola ±3%. Bolodi la 250 gsm likhoza kukhala pakati pa 242.5 ndi 257.5 gsm. Ogulitsa akufuna kuchepetsa mtengo wa bolodi popanda kuuma.
- Kuuma kwa Taber (MD + CD)
Miyezo yoyezedwa, osati yodziwika. Kulimba kwa MD kochepa → kutseka kwa chivindikiro chomasuka. Kulimba kwa CD kochepa → mphamvu yofooka ya kukanikiza bokosi.
- Kukhwima kwa pamwamba (PPS 10 μm)
Iyenera kukhala ≤ 1.5 μm pa ISO 8791-4. Pa mawu omwe ali pansi pa 6 pt, pemphani ≤ 1.0 μm.
- Mphamvu Yapamwamba (Liwiro Lotola la IGT)
Osachepera 1.2 m/s pa ISO 3783 iliyonse. Pansi pa izi, kusindikiza kwachangu kwambiri kapena UV kungayambitse kupukuta.
- Chinyezi Chokwanira
Cholinga chake ndi 7.0% ± 1.0%. Kukwera kwambiri → mavuto ouma. Kutsika kwambiri → kufooka kwa bolodi. Chofunika kwambiri m’misika yotentha (Middle East, Southeast Asia).
- Ziphaso
ISO 9001, FSC-COC, ndipo ngati pakufunika kukhudzana ndi chakudya — kutsatira malamulo a FDA 21 CFR 176.170 kapena malamulo ofanana ndi a m’deralo.
Chidule cha Kupereka Mapepala a Paperjoy GC1
Zinthu za Paperjoy Bolodi la mapepala la GC1kwa opanga ma CD ndi eni ake padziko lonse lapansi ndi izi:
| Chizindikiro | Zosankha |
| Kulemera | 170–400 gsm |
| Kuphimba | Chophimba cha mchere cha mbali imodzi (chokhazikika), chosankha cha PE |
| Fomu | Mipukutu ikuluikulu (yapakati 3/6/12 inchi) kapena mapepala (kukula kopangidwa mwamakonda) |
| Gwero la zamkati | Chophimba cha mankhwala chopakidwa utoto + chapakati cha CTMP (chachikazi, palibe chobwezeretsanso) |
| Ziphaso | ISO 9001, FSC-COC, FDA 21 CFR 176.170 (ngati yakutidwa ndi PE) |
| Kulekerera kudula | ± 2 mm |
| Nthawi yotsogolera | Masiku 20–30 |
| Misika yolunjika | Kum’mwera chakum’mawa kwa Asia, Middle East, Europe, Africa |
Mukawonjezera PE coating (7–45 gsm) ku GC1, dziwani kuti PE layer imawonjezera 7–45 μm ku total caliper koma ili ndi mphamvu yochepa pa kuuma kwa mbali. Mbali ya PE iyenera kuyang’ana mkati (chotchinga chinyezi) ndipo mbali yokhala ndi mchere iyenera kuyang’ana kunja (pamwamba posindikiza) – izi ndizofunikira kwambiri.

Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri)
Q: Kodi kusiyana pakati pa bolodi la mapepala la GC1 ndi GC2 ndi kotani?
Yankho: GC1 ili ndi kumbuyo koyera (mankhwala opaka utoto), pomwe GC2 ili ndi kumbuyo koyera/kwachilengedwe (mankhwala opaka utoto). Zonsezi zili ndi utoto wa mchere wakutsogolo. Sankhani GC1 pamene mkati mwa phukusili mukuwonekabe; sankhani GC2 pamene kunja kwa kutsogolo kokha kuli kofunika.
Q: Kodi bolodi la mapepala la GC1 limagwiritsidwa ntchito pa chiyani?
A: Ntchito zinayi zazikulu: (1) Kupaka mankhwala pa 210-250 gsm; (2) Zodzoladzola ndi ma phukusi apamwamba ogulitsa pa 270-350 gsm; (3) Kupaka chakudya chouma pa 230-300 gsm; (4) Kupaka zamagetsi ndi zowonetsera zamalonda pa 250-350 gsm.
Q: Kodi mapepala a GC1 ayenera kukhala ndi ziphaso ziti?
A: ISO 9001 yoyang’anira bwino, FSC-COC yopezera nkhalango mokhazikika, komanso yogwiritsira ntchito kulumikizana ndi chakudya — FDA 21 CFR 176.170 kutsatira kapena malamulo ofanana ndi a m’deralo.
Q: Kodi mungayang’ane bwanji khalidwe la bolodi la mapepala la GC1 musanayitanitse?
A: Mndandanda wa mfundo zisanu ndi chimodzi: (1) Kulekerera kwa grammage ±3%; (2) Kulimba kwa Taber MD+CD yoyesedwa; (3) Kukhwima kwa pamwamba PPS ≤ 1.5 μm; (4) Mphamvu ya pamwamba IGT ≥ 1.2 m/s; (5) Chinyezi 7.0%±1.0%; (6) Ziphaso za ISO+FSC+FDA.
Q: Kodi GC1 ingagwiritsidwe ntchito popangira chakudya?
Yankho: Inde pa chakudya chouma monga mabisiketi ndi makeke. Komabe, mbali yakumbuyo siinapangidwe kuti igwirizane ndi chakudya. Kuti chakudya chigwirizane ndi mbali ziwiri, sinthani ku C1S Ivory Board kapena onjezani PE coating. Nthawi zonse yang’anani malire osamukira ndi COA ya wogulitsa wanu.
Kutseka
Bukuli likufotokoza mfundo zofunika kwambiri zopezera bolodi la mapepala la GC1 — kuyambira kumvetsetsa kapangidwe kake ka magawo atatu ndi zofunikira zake mpaka kusankha giredi yoyenera yogwiritsira ntchito popakira. Kuti mudziwe mitengo yomwe ilipo, zopempha zachitsanzo, kapena mafunso aukadaulo okhudza polojekiti yanu, funsani Paperjoy mwachindunji.
