Sephutheloana sa vacuume na le litšobotsi tse latelang:
1.High mokoallo tshebetso
Filimi e sebelisetsoang ho kenya vacuum e tla ba e nang le khase e ntle ea khase, joalo ka lifilimi tse fapaneng tsa PVDC tse koahelang, PVDC OPP, PVDC pet, PVDC nylon, filimi ea Eval, filimi ea nylon le filimi ea PET, e loketseng lihlahisoa tsa mekotla ea vacuum.Hoo e ka bang liphutheloana tsohle tsa boroso tsa vacuum li sebetsoa ka ho sebelisa filimi e kopaneng e hlahisoang ke filimi ea nylon e otlolohileng ea biaxially le polyethylene e tlase-tlase.Filimi ena e na le nako ea tiiso ea boleng bo botle.Hoo e ka bang lihlahisoa tsohle tse tlase, liaparo tse tlase le liphahlo tse tlase li tletse filimi ea PVDC e le lisebelisoa tse tala, tse ka fokotsang molumo nakong ea lipalangoang le ho boloka thepa.
2. khanyetso ea sekoti
Ntle le ho nahana ka thepa ea mokoallo ea thepa, ntlha ea bobeli ea khetho ea thepa le moralo oa sebopeho ke ho hanyetsa pinhole.Sebopeho sa thepa feela se nang le khanyetso e ntle ea pinhole se ka mamellang likhohlano le likoti tse bakoang ke ho phutha nakong ea ho tlatsa le ho tiisa mocheso, lipalangoang, polokelo, thekiso le tšebeliso.Etsa hore sephutheloana sa vacuum se kenelle moea.Thepa ea ho paka ea vacuum e entsoeng ka filimi ea biaxial tensile nylon le filimi ea polyethylene e nang le mela e tlase e hlahisoang ke k'hamphani ea rona e na le khanyetso e ntle ea pinhole, boima bo matla le thepa e phahameng ea lithibelo.
