Njengezinto zokuprinta, ifilimu yeplastiki yeengxowa zokutya ukutya inembali emfutshane. Inezibonelelo zokukhanya, ukungafihli nto, ukunyangwa kwe-oxygen, ubungango, ubungangamsha kunye nokunganyayo kwempahla, kwaye kunokuvelisa imilo yemveliso. nombala. Ngokuphuhliswa kweshishini lePetrochemical, zininzi kwaye iintlobo ezininzi zefilimu zeplastiki. Iifilimu ezisetyenziswayo zeplastiki ezisetyenziswayo yi-Polythylene (PE), ifilimu ye-bolyester Alize (VMEEST), ifilimu ye-Pontuster (Polyster), iPolyproplene (PP), inylon, njl.
Iipropathi zeefilimu ezahlukeneyo zeplastiki zahlukile, ubunzima bokuprinta ukwahlukile, kwaye ukusetyenziswa njengoko izinto zokupakisha nazo zahlukile.
Polyethylene film is a colorless, tasteless, odorless, translucent non-toxic thermal insulation material, which is widely used in bag making. Yinto engaphakathi, ngoko ke kuya kuba nzima ngakumbi ukuprinta kwaye kufuneka kwenziwe ukuprinta ngcono.
Ifilimu ye-ALMIMED inazo zombini iimpawu zefilimu yeplastiki kunye neempawu zensimbi. Umphezulu wefilimu udityaniswe nge-aluminium ukukhusela ngokuchasene ne-radiation ye-UV kunye ne-UV, engapheliyo yobomi beshelufu yomxholo, kodwa ukwandisa ukuqaqamba kwefilimu. Ithatha indawo ye-aluminum foil ukuya kuthi ga kwinqanaba elithile, kwaye inezibonelelo zexabiso eliphantsi, imbonakalo elungileyo kunye neepropathi ezifanelekileyo. Iifilimu ze-Alwemince zisetyenziswe ngokubanzi kwiphakheji yokuhlanganisa. Isetyenziswa ikakhulu ekupakishweni kowomileyo kunye nokutya okuphezulu, kunye neebhiskithi, kunye nokupakishwa kwangaphandle kwamayeza kunye ne-cosmetics.
Ifilimu ye-polyester ayinantsingiselo kwaye ingabonakali, i-suintain-finsol, i-air-amandla, i-alkali, ioyile kunye ne-solvent, kwaye ayoyiki ubushushu obuphezulu nophantsi. Emva konyango lwe-EDM, lube nokungaphezulu komhlaba ngokukhawuleza kwi-inki. Yokupakisha kunye nezixhobo ezihlanganisiweyo.
Ifilimu yePolyPropylene ineebross kunye nokungafihli nto, ukumelana nobushushu, i-Acid kunye neAlokali Ukunganyangeki, ukumelana ne-Solvent, ukumelana ne-ibrasion, ukumelana i-arasion, intengo ye-abrasion, i-rasion ilunge kakhulu. Ayinakuba bubushushu batywinwe ngaphantsi kwe-160 ° C.
Ifilimu yenylon yomelele kunefilimu ye-Polythylene, i-odols, engenatyhefu, kwaye ingenabungozi kwi-bacteria, ioyile, amanzi abilayo kunye nezinto ezininzi. Isetyenziselwa ukuthwala umthwalo, ukupakisha okunganyangekiyo nokunganyangeki kunye nokupakisha kwakhona (ukulungisa ngokutya) kwaye kuvumela ukuprintwa ngaphandle konyango olungaphantsi konyango.
Iindlela zokuprinta zefilimu zeplastiki zibandakanya ukuprintwa okuPrinta, ukugqatswa komdlalo kunye nokushicilelwa kunye nokushicilelwa. I-inki yokuprinta ifuna ukuviswa okuphezulu kunye nokunamathela okuqinileyo, ngoko ke iimolekyuli ze-inki zilandela ngqo umphezulu weplasitiki kwaye zahlulwe ngokulula kwi-oxygen emoyeni ukuba yomile. Ngokubanzi, i-inki yefilimu yeplastiki yokuprinta iqulunqwa i-wine ye-wine kunye ne-organic slin enotywala kunye ne-inki eyomileyo yenziwa ngombane owomileyo kunye nokusasazeka ukwenza i-colloidal fluid. Ineempawu zokusebenza okuhle okuprinta, i-adhesion eyomeleleyo, umbala oqaqambileyo kunye nokoma ngokukhawuleza. Ilungele ukuprinta kunye nevili lokushicilela le-cocave.
Ndiyathemba ukuba eli nqaku linokukunceda kwaye likwazise ngakumbi malunga nokupakisha.
