Sealing Zaj duab xis Khoom Siv Khoom

Sealing films feem ntau muaj peb lossis ntau txheej txheej nrog cov haujlwm sib txawv. Piv txwv li, aluminium foil sealing composite khoom tau piav qhia hauv cov ntaub ntawv patent muaj xws li biaxially oriented polyester film (PET) substrate txheej (7-25μm), aluminium foil (AL) txheej txheej (7-50μm), thiab polyethylene (PE) tshav kub-60μm). Cov khaubncaws sab nraud povtseg no tau sib koom ua ke nrog cov nplaum los tsim tus qauv PET / AL / PE. Cov txheej thaiv txheej thaiv zoo thaiv cov pa oxygen thiab dej vapor permeation, thaum lub tshav kub-seal txheej ua kom muaj kev ruaj ntseg nrog lub thawv qhib. Qee cov khoom lag luam, xws li electromagnetic induction sealing films, suav nrog elastomer lossis cardboard txheej los txhim kho cov khoom pov thawj thiab tsim kua muag.
