Lub khob ntawv ripple yog hom ntawv pov tseg uas tsim los rau kev haus dej haus txhua hnub. Zoo li lub khob haus dej, nws muaj cov phab ntsa sab nrauv uas muaj txheej txheem zoo nkauj, corrugated ntawv ridges uas muab thermal rwb thaiv tsev; nws sawv cev rau ib qho kev txhim kho ntawm cov txheej txheem pov tseg daim ntawv khob. Nws lub khob phab ntsa siv cov qauv sib xyaw uas muaj cov ntawv coated laminated nrog cov ntawv corrugated, thiab cov peev txheej ntau ntawm 4.5 txog 16 ooj (lossis 150 txog 500 milliliters). Cov qauv tsim muaj qhov zoo dua qub: siab compressive zog thiab kev tiv thaiv zoo tiv thaiv scalding.
Nyob rau hauv 2003, ib tug tshwj xeeb automated ntau lawm kab rau cov khob no commissioned nyob rau hauv lub Lingang Industrial Park nyob rau hauv Shanghai. Tsim los ntau xyoo, cov kab ntau lawm no tau ua kom muaj kev tsim khoom loj, ua tiav cov txiaj ntsig txhua hnub ntawm ntau dua 3,000 square metres ntawm cov khoom siv ua haujlwm. Cov khoom tom qab ntawd tau txais txiaj ntsig Silver Prize rau Khoom Noj-Related Inventions los ntawm National Ministry of Light Industry. Los ntawm 2008, kev noj haus hauv tsev ntawm cov khob no tau mus txog kwv yees li 50 lab units. Txij li xyoo 2018, cov tuam txhab tsim khoom hauv tsev tau ua kom zoo dua tus qauv tsim los ntawm daim ntawv thov patent- suav nrog cov yam ntxwv xws li cov kab noj hniav hollow, cov txheej txheem tshuaj tua kab mob, thiab cov qauv nqa tau yooj yim- txhawm rau txhim kho kev tiv thaiv dej, rwb thaiv tsev thermal, thiab collapsibility. Tsis tas li ntawd, kev txhim kho cov txheej txheem- xws li kev saws ib leeg -txheej tes tsho corrugated- tau pab txo cov nqi tsim khoom.
