Ob daim ntawv thov ntxiv. Lub tes tsho Multipack feem ntau luam tawm, thiab cov duab distorted thaum lub sij hawm shrinking, yog li kev sau npe raug thiab shrink ratio yuav tsum tau kho ua ke. Cov nroj tsuag zaub mov thiab dej haus kuj xav tau zaub mov- tiv tauj rau kev ua raws cai, thiab cov neeg xa khoom ua yeeb yaj kiab tuaj yeem muab cov ntawv tshaj tawm kom paub meej cov neeg xa khoom tshawb xyuas yooj yim dua.
4. Case Wrapping thiab Logistics: Sib npaug zog thiab nqi
Case wrapping thiab palletized logistics xav tau qee yam txawv ntawm cov khw muag khoom ntau. Cov khw muag khoom saib ntawm qhov tsos thiab kev nthuav qhia. Logistics saib ntawm kev tsim kua muag, pallet stability thiab tus nqi ib rooj plaub.
Tus nqi tam sim no qhia tau hais tias qhov sib txawv ntawm qhov stretch qhwv thiab shrink zaj duab xis. Standard tshuab stretch qhwv tuaj yeem poob qis li 13 CNY ib kg, thaum zaub mov - qib kev cai shrink zaj duab xis pib siab dua 14 CNY ib kg, nrog cov yeeb yaj kiab txawv teb thiab siab - kawg tuag kab raug nqi ntau dua.Tus nqi sib txawv qhia qhov sib txawv ntawm qhov sib piv, thickness uniformity thiab tsim kua muag.Rau cov neeg siv khoom thauj khoom, xaiv ntawm tus nqi tsev ib leeg txhais tau tias tus nqi zais ntawm cov yeeb yaj kiab tawg thiab cov pallets tawg hauv lub caij nyoog siab tshaj qhov sib txawv ntawm cov khoom siv.
Peb txoj hauv kev los txiav cov nqi hauv kev siv logistics:
1. Tsa qhov sib piv.Ntawm qhov sib npaug ntawm cov yeeb yaj kiab hnyav, qhov sib piv ntau dua tso cai rau lub ntsuas qhov sib npaug, txiav cov yeeb yaj kiab hnyav rau ib rooj plaub ncaj qha. Qhov no xav kom tus neeg muag khoom sib npaug sib npaug ntawm qhov sib npaug ntawm lub zog hauv kev tsim. Kev txuag ntawm ib zaj duab xis uas tawg feem ntau tau so los ntawm lub sijhawm poob.
2. Ua kom zoo pallet qhov ntev.Thaum cov yeeb yaj kiab dav sib piv nrog pallet loj, cov txiaj ntsig ib yob khiav ntau dua. Qhov kev coj ua ib txwm yog kom muaj cov yeeb yaj kiab zeb txiav qhov dav rau qhov tseeb pallet qhov ntev es tsis yog yuav cov qauv dav thiab txiav hauv - tsev. Cov ntug trimmed yog tus nqi ib yam.
3. Down- ntsuas thaum tuav lub zog.Cov ntaub ntawv kev lag luam qhia tau hais tias zaj duab xis qis -gauge offsets 8% mus rau 12% ntawm tag nrho cov nqi. Qhov no yog cov npoo ntshiab, tab sis nws xav tau cov ntaub ntawv ruaj khov tom qab nws. Nug cov neeg muag khoom rau qhov sib txawv ntawm qhov tuab ntawm cov khoom sib txawv thiab ua kom muaj kev sib txawv hauv ib qho khoom siv tau.
5. Plaub Daim Ntawv Pom Zoo rau Cov Neeg Yuav Khoom
1. Nqa cov khoom tiag rau cov qauv khiav. Hla cov qauv qauv.Lub tes tsho Multipack yuav tsum tau sim ntawm koj tus kheej lub raj mis kom paub tseeb tias qhov qis qis, kub hnyiab thiab luam tawm distortion. Case zaj duab xis xav tau kev sim nrog lub pallet tiag tiag thiab cov ntaub ntawv tiag tiag.
2. Muab cov coefficient ntawm kev sib txhuam hauv kev pom zoo.Qhov no yog qhov kev txwv ntawm txoj kab ceev. Kev qhia txog ntau yam muaj txiaj ntsig ntau dua li sau cov thickness thiab shrink ratio ib leeg.
3. Tsim cov khoom siv dual resin.Khaws ib tus neeg muag khoom tsim nyog rau PE thiab POF, thiab rau LLDPE thiab LDPE. Nyob rau hauv ib theem zoo li Lub Kaum Hli, qhov twg cov khoom siv hauv tsev thiab cov khoom lag luam tuaj yeem nce thiab cov xwm txheej loosen, muaj cov khoom muaj teeb meem ntau dua li muaj tus nqi qis tshaj.
4. Taug qab cov ntsiab lus rov siv dua txoj cai raws li kev xaiv ntev -.Lub ntiaj teb no recyclable shrink zaj duab xis kev lag luam muaj nuj nqis ntawm 2.79 billion USD nyob rau hauv 2025 thiab yog npaj kom ncav cuag 5.09 billion USD los ntawm 2034, ib tug compound txhua xyoo kev loj hlob tus nqi ntawm 6.9%. Recycled LDPE resin nqa 15% mus rau 25% premium tshaj cov ntaub ntawv nkauj xwb, thiab nqes -gauge processes offset 8% to 12% of that. Rau cov zaub mov thiab dej haus, qhib kev sib tham ntawm PCR sib xyaw tam sim no tsis tshua muaj nrawm dua li raug thawb los ntawm txoj cai hauv 2029.
6. Cov khoom siv-Siab duab
Kev xa khoom PE hauv tsev tau qhia txog kev hloov pauv thaum Lub Kaum Hli. Lub Cuaj Hlis lub teb chaws cov khoom lag luam kwv yees li ntawm 2.7233 lab tonnes, nqis 2.27% lub hli nyob rau lub hli. Lub kaum hli ntuj muaj tsawg dua qhov teem caij tu ncua thiab hnub ua haujlwm ntau dua, yog li cov khoom tsim tawm yuav tsum rov qab los, thiab qis dua - tus nqi ntawm North American cov khoom xa tuaj ua ntej tuaj txog tam sim no.Tight nyob rau hauv lub sij hawm luv luv, xoob dhau lub sij hawm ntev.Qhov ntawd yog qhov kev pom tseem ceeb tam sim no.
Rau cov neeg yuav khoom qhov kev nyeem ntawv yog qhov no. Tsis tas yuav tsum khaws cia hnyav ntawm qhov siab tshaj plaws hauv Q4, tab sis cov khoom muag yuav tsum tsis txhob nyem rau qhov tsis txaus. Ib txwm ntxiv ntxiv rau cov khoom lag luam muaj kev nyab xeeb me ntsis yog txaus. Nyob rau tib lub sijhawm, nqes - ntsuas thiab ob qhov khoom muaj nqis tam sim no ntau dua li tom qab cov nqi resin thim rov qab rau xyoo tom ntej, vim tias cov nyiaj khaws cia tau nce thoob plaws txhua lub xyoo.
Nyob rau hauv ntim zaj duab xis, technical parameters thiab nqi qauv yog ob qho tib si pob tshab. Cov neeg yuav khoom tsuas ntsib ob qhov kev txiav txim siab tiag tiag:puas qhov specification phim koj lub raj mis thiab kab, thiab qhov kev yuav khoom zoo li cas rau lub voj voog resin.Thaum ob qhov no tau txiav txim siab, kev xaiv tus neeg muag khoom yuav ncaj nraim.
