Kutheni izongezo zeSlip kunye ne-Anti-Block zibalulekile kwimveliso yefilimu yeplastiki?

Izongezo zokutyibilika kunye nezongezo ezichasene nokuvimbaZisetyenziswa kwimveliso yefilimu yeplastiki, ingakumbi kwizixhobo ezifana neepolyolefins (umz., i-polyethylene kunye ne-polypropylene), ukuphucula ukusebenza ngexesha lokwenziwa, ukucutshungulwa, kunye nokusetyenziswa kokugqibela. Nantsi isizathu sokuba zixabiseke:
Izithako zokutyibilika zinciphisa ukungqubana phakathi kwemiphezulu yefilimu okanye phakathi kwefilimu nezixhobo. Oku kwenza kube lula ukuba iifilimu zihambe kakuhle kwimigca yemveliso, kuzithintele ekunamatheleni koomatshini, kwaye kuphucula indlela yokuphatha imisebenzi yokupakisha. Umzekelo, ngaphandle kwezithako zokutyibilika, ifilimu yeplastiki inokutsala okanye ixinge ngexesha lokucubungula ngesantya esiphezulu, inciphise isantya sezinto okanye ibangele iziphene. Zikwanceda kwizicelo ezifana neengxowa okanye ii-wraps, apho ufuna ukuba iileya zityibilike lula xa zivuliwe.
Izongezo ezichasene neebhlokoKwelinye icala, zijongana nengxaki eyahlukileyo: ziyayithintela imiqolo yefilimu ukuba inamathele, ingxaki eqhelekileyo eyaziwa ngokuba “kukuvinjwa.” Ukuvinjwa kwenzeka xa iifilimu zicinezelwe ndawonye—masithi, kwiroli okanye kwinqwaba—kwaye zinamathela ngenxa yoxinzelelo, ubushushu, okanye ukubambeka kwazo kwendalo. Izongezo ezichasene ne-block zenza ukungalungelelani komphezulu okuncinci, kunciphisa unxibelelwano phakathi kwemiqolo kwaye kwenze kube lula ukukhulula imiqolo okanye amaphepha ngaphandle kokukrazula.
Xa zizonke, ezi zongezo ziphucula ukusebenza kakuhle kunye nomgangatho. Zikhawulezisa imveliso ngokunciphisa ixesha lokungasebenzi ngenxa yemiba yokunamathela okanye yokungqubana, ziphucula ukusetyenziswa kwemveliso yokugqibela (cinga ngeengxowa zeplastiki ezilula ukuzivula), kwaye zigcina ukucaca okanye ezinye iimpawu ezifunekayo xa zilinganiswe ngokufanelekileyo. Ngaphandle kwazo, abavelisi bebeya kujongana neenkqubo ezicothayo, inkunkuma eninzi, kunye nemveliso engasebenzi kakuhle—iintloko ezibuhlungu ezingafunwayo ngumntu.

OkuqhelekileyoIzithako zeSlip kwiifilimu zeplastiki
