Nws yog qhov zoo tshaj plaws rau cov ntawv thov uas xav tau kev tiv thaiv siab lossis kev ua yeeb yam ntawm cov khoom lag luam 3D profile- xws li hauv ntim cov khoom noj tsiaj thiab khoom noj txom ncauj.
Cov yam ntxwv tseem ceeb ntawm yim- sab foob hnab
● Kev ua tau zoo tshaj plaws ntawm kev sib khi: yim- sab foob qauv ua tiav los ntawm ntau- txheej txheej thaum tshav kub kub sealing, muab airtightness zoo dua li cov hnab ntim khoom txheem. Hauv daim ntawv thov ntim khoom noj, piv txwv li, cov pa xa tawm tuaj yeem khaws cia qis dua 20 cm³ / m²·24h (saib tus qauv GB / T 1037-2021, "Test method for gas permeability of plastic film"), txuas ntxiv lub neej txee.
● Kev thauj khoom siab-cov kabmob muaj peev xwm: Ua tsaug rau nws cov qauv kev txhawb nqa ntau- sab, lub hnab tuaj yeem txhawb nqa qhov hnyav ntawm 5-10 kg (nyob ntawm cov khoom tuab), ua rau nws haum rau cov khoom hnyav xws li mov thiab miv litter.
