Ncab zaj duab xis, raws li cov khoom siv tseem ceeb, yog siv dav dav thiab cov kev siv tshuab, tsom mus rau cov khoom siv Stretch, ua kom zoo dua qub, thiab kev txhim kho kom zoo dua qub.
Hais txog cov khoom hloov kho, zaj duab xis tsoosab ib txwm muaj feem ntau yog cov kws tshawb fawb muaj zog (LLDPE), tab sis cov kws tshawb fawb tau txhim kho nws cov khoom siv tshuab los ntawm kev sib xyaw. Piv txwv li, txuas rau ntawm metallocene polyethylene (Mpe) nrog cov PE tseem ceeb ua rau cov zaj duab xis tensile lub zog thiab puncture tsis kam. Tsis tas li ntawd, kev qhia ntawm nanocomposites, xws li montmorillonite lossis carbon nanotubes, ntxiv rau cov yeeb yaj kiab rigidity, thiab thermal stability.
Kev ua kom zoo dua yog tseem tshawb nrhiav hotspot. Improvements in pre-stretching technology and multi-layer co-extrusion processes have enabled stretch films to reduce thickness and increase load-bearing capacity per unit area while maintaining high transparency. Nyob rau hauv xyoo tsis ntev los no, kev sib xyaw ua ke ntawm cam thiab tshuab moulding tau coj los txhim kho hauv ob qho yeeb zaj duab xis ntau lawm thiab cov khoom zoo. Nyob rau hauv cov nqe lus ntawm kev nthuav dav, cov neeg tshawb xyuas tau ua haujlwm los txhim kho cov yeeb yaj kiab tshwj xeeb, xws li UODGACTERS, lossis cov tshuaj tua kab mob tawm tsam. Kev siv bio - Raws polymers (PLA) yog tsav tsheb ntawm cov yeeb yaj kiab nruj kom tau raws li cov kev xav tau ntawm kev siv hluav taws xob kom ruaj ntseg.
Nyob rau hauv lub neej yav tom ntej, nrog kev cog qoob loo mus rau ntsuab tsim khoom thiab cov ntse ntim, ncab zaj duab xis kev sib npaug ntawm kev ua tau zoo, ib puag ncig kev phooj ywg, thiab kev ua haujlwm. Los ntawm cov khoom tsim tshiab thiab cov txheej txheem tshiab, ncab zaj duab xis xav tias yuav ua lub luag haujlwm loj dua hauv kev logistics, kev ua liaj ua teb, thiab ntim ntim hauv kev ua liaj ua teb.
