Kub yaj nplaum nplaum tas mus li sealing daim kab xev yog ib puag ncig tus phooj ywg nplaum siv rau sealing cardboard thawv. Taw qhia hauv xyoo 1960, nws yog tsim los ntawm cov nplaum nplaum rau hauv lub tshuab kub yaj thiab tom qab ntawd txau rau saum npoo ntawm lub thawv ntawv kom ua tiav adhesion. Nws lub luag haujlwm tseem ceeb yog los hloov cov kab xev ib txwm siv lossis cov hlua khi, thiab nws tau siv dav hauv kev ntim khoom, tshwj xeeb tshaj yog cov neeg txawv teb chaws - nqis peev lag luam hauv Tebchaws Europe thiab Asmeskas. Cov tuam txhab lag luam muaj xws li Zhengzhou Weis Tshuaj thiab Guangdong Weiwang Cov Khoom Tshiab.
Cov khoom no siv APAO (olefin copolymer) raws li nws cov khoom tseem ceeb thiab yog sib xws nrog kub yaj kua nplaum phom los yog tag nrho automated khoom. Nws nta kev kho sai (tsawg dua lossis sib npaug li 3 vib nas this), qis -kub tsis kam (-40℃txog 80 degree), thiab lub zog nplaum siab, txhim kho qhov compression tsis kam ntawm cov thawv ntawv thiab tiv thaiv deformation thiab tawg. Nws txoj kev nkag mus rau kev sib txuas tuaj yeem ua rau cov duab los qhia cov fibers kom ua tiav kev tiv thaiv tub sab yam tsis muaj kev cuam tshuam cov ntim luam ntawv. Piv nrog rau cov kab xev ib txwm muaj, nws muaj lub neej txee ntev txog 2 xyoos, txo cov nqi tsev los ntawm kwv yees li 75%, thiab sib haum nrog cov kab ntau lawm, txo qis sijhawm. Cov khoom lag luam tau dhau EU RoHS ntawv pov thawj thiab SGS kuaj, ua tau raws li cov qauv kev xa tawm ib puag ncig rau cov zaub mov, tshuaj, thiab khoom siv hluav taws xob.
