| 70% Virgin / 30% rov siv dua | Zoo heev | Zoo heev | 100-150 khob / min |
| 50% nkauj xwb / 50% rov siv dua | Nruab nrab | Nruab nrab | 60-100 khob / min |
| 100% rov qab | Cov neeg pluag | Cov neeg pluag | Siab - tsis pom zoo tsav tsheb ceev. |
Lub koom haum UN Industrial Development Organization (UNIDO), nyob rau hauv nws cov khoom ntim Cov Lus Qhia rau SMEs 2023, tau txheeb xyuas cov fiber ntau yog qhov tseem ceeb. Tab sis nws yog feem ntau overlooked. Lawv pom peb zaug ntau npaum li cov khoom noj jams ntawm cov kab ntau lawm uas siv cov ntawv uas muaj ntau cov fiber ntau rov siv dua li ntawm cov kab uas siv cov tawv nqaij nyoos.
Rau lub siab - khob ceev - ua tshuab, nqaij nyoos los yog sib tov nrog cov fiber ntau nyoos tsis yog ib qho kev xaiv. Lawv tsim nyog. Ib tug txhim khu kev qhakev kub ceev ntawv khob ua tshuabnyob ntawm qhov ntev fiber ntau los tswj nws lub voj voog nrawm yam tsis muaj clogging.
4. Txheej Txheej: PE, PLA lossis tsis muaj txheej?
Feem ntau cov zaub mov- qib khob yuav tsum muaj ib txheej moisturizer. Qhov ntawd tuaj ntawm ib txheej ntawm daim ntawv. Hom txheej txheej ncaj qha cuam tshuam rau kev ua haujlwm ntawm siab - ceev daim ntawv khob molding tshuab hauv txheej txheem sealing.
| Txheej hom | Melting Point | Foob Compatibility | Kev ntsuas ceev |
|---|---|---|---|
| PE (polyethylene) | 110-130 degree | Zoo rau ultrasound | 120-200 khob / min |
| PLA (polylactic acid) | 150-170 degree | Zoo - kub dua yog xav tau | 80-140 khob / min |
| Ob chav PE (sab hauv + tawm) | 110-130 degree | Zoo heev | 100-160 khob / min |
| Uncoated (kraft nkaus xwb) | N/A | Tsis tas yuav tsum tau sealing | 150-200 khob / min |
PE-coated ntawv yog ib qho kev xaiv nrov rau cov khob haus dej kub. Nws tam sim ntawd melts thiab khi nyob rau hauv ultrasonic tshav kub. PLA yog ib qho tseem ceeb ntawm lub khob. Tab sis nws yuav tsum tau sealing ntau dua thiab qeeb qeeb lub sij hawm.
Lub koom haum World Intellectual Property Organization (WIPO) patent database qhia tau hais tias muaj kev nce ntxiv hauv ultrasonic sealing patents txij li xyoo 2020. Cov patents no yog siv los ua cov ntawv polylactic acidcoated. Nws tuaj yeem pom tau tias qhov ceev ntawm biodegradable coatings tseem nyob hauv kev tshawb fawb kev lag luam.
European Committee for Standardization (CEN) hais tias cov cav tov ua PLA coated ntawv yuav tsum muaj ib tug nyias muaj nyias ib cheeb tsam rau lub hau. Qhov ntawd ntxiv txog 2,000-4,000 las rau cov nqi tshuab.
5. Daim ntawv yob Dimensions thiab Core Size
Uas suab tsis tseem ceeb. Nws tsis yog.
Siab- khob ceev- ua tshuab xav tau cov yob uas phim zoo rau nws cov coiling system. Ob qhov tseem ceeb specifications:
| Tsis muaj | Standard Range | Vim li cas thiaj tseem ceeb |
|---|---|---|
| Curl dav | 200-450 hli | Yuav tsum phim lub khob txoj kab uas hla + ntim cov kua khib nyiab |
| Core txoj kab uas hla | 76 hli (3 nti) lossis 152 hli (6 nti) | Yuav tsum phim lub tshuab spindle |
| Qhov siab tshaj plaws yob txoj kab uas hla | 800-1200 hli | Txiav txim siab ntev npaum li cas koj tuaj yeem khiav ua ntej reloading |
Yog hais tias lub yob yog nqaim heev, daim ntawv yuav nkim ntawm cov npoo. Yog tias nws dav dhau, daim ntawv khoov hauv qhov chaw pub. Raws li OECD's 2023 kev tsim tus nqi Performance index, qhov tsis sib haum xeeb hauv yob qhov loj me ua rau kwv yees li 8% cov khoom siv khib nyiab hauv siab - khob ceev ntau lawm.
Nco ntsoov xyuas cov reel specifications nrog lub tshuab tsim ua ntej xaj ntawv. Cov yob tsis sib xws txhais tau tias koj cov khoom yuav tsum nres. Qhov no yog ib qho tsis yog - daim ntawv teev npe sib tham tau rau ib qho twgkev kub ceev ntawv khob ua tshuab.
6. Printing Quality thiab Ink Compatibility
Yog tias koj lub khob muaj qhov tsim ua ntej - luam tawm, tus number case tseem ceeb tshaj qhov koj xav.
Ink qhuav tsis tiav yuav stain nyob rau hauv siab -kub tsim theem 80-120℃). Ink ntxiv ib qho hnyav, tuaj yeem tiv thaiv PE txheej rau daim ntawv. Qhov no ua rau cov txheej txheem poob thaum lub sij hawm sealing.
Lub koom haum Packaging Machinery Manufacturers (PMMI) pom zoo kom siv dej -raws li inks. Nws yuav siv sij hawm tsawg kawg 24 teev kom tus number case kom qhuav tag ua ntej daim ntawv mus txog qhov siab - khob tshuab ceev. Cov kuab tshuaj-raws li inks siv sijhawm 48–72 teev.
Flexographic luam ntawv yog ib qho kev xaiv nrov rau cov khob ntawv. Nws puv nyias, txawm tus number case txheej, tsis muaj kev puas tsuaj rau txoj kev tsim. Offset luam ntawv muab cov duab zoo dua. Tab sis nws siv ib txheej tuab ntawm tus number case. Thaum ntau tshaj 120 khob ib feeb, cov no tuaj yeem ua rau muaj teeb meem noj.
7. Ntawv tawv thiab Caliper Consistency
Lub hardness yog ntsuas nyob rau hauv mNm, lub caliper yog ntsuas nyob rau hauv micron thickness, thiab lub hardness ntawm tag nrho cov yob yuav tsum yog tib yam.
Siab -cov ntawv khob ceev tuaj yeem tsim cov khob hauv tsawg dua 2 vib nas this. Yog tias ib feem ntawm daim ntawv yog tuab dua thiab lwm qhov yog nyias, txoj kev tuag tsis kho sai txaus. Qhov tshwm sim yog cov phab ntsa tsis sib xws, tsis zoo stacking thiab tsis zoo sealing.
ITC cov ntawv xov xwm hais tias caliper hloov ntawm ib yob yuav tsum tsis pub tshaj ± 5%. Kev hloov tawv tawv yuav tsum tsis txhob ntau tshaj ± 8%. Txhua tus neeg xa ntawv uas tsis ua raws li cov kev txwv no tuaj yeem ua rau muaj teeb meem, txawm tias koj lub tshuab zoo npaum li cas.
8. Khoom noj khoom haus- Daim Ntawv Pov Thawj Qib: Tsis yog- hloov pauv tau
Txhua qhov kev sib cuag zaub mov uas siv hauv lub tshuab khob ntawv yuav tsum tau sau tseg kom raug. Hauv kev lag luam feem ntau, qhov ntawd txhais tau tias ua raws li FDA cov cai hauv Tebchaws Meskas, EU Txoj Cai 1935/2004 hauv Tebchaws Europe lossis cov qauv hauv tebchaws zoo sib xws.
Cov ntawv tsis muaj ntawv pov thawj, txawm tias thaum ua haujlwm hauv tshuab, teeb meem kev cai lij choj thiab teeb meem rau kev xa tawm, raws li tsab ntawv tshaj tawm xyoo 2022 los ntawm United Nations Food and Agriculture Organization. Cov tshuab siv cov ntawv tsis muaj ntawv pov thawj tsis yog cov cuab yeej tsim khoom. Qhov no yog kev tswj hwm kev pheej hmoo.
