YFML-720、920、1200 semi-automatichydrauliclaminating machineis
designedanddevelopedbyourselves accordingtothemarketneeds.
Thismachinestress theconcept basedon human’,andiseasytotestand
operate.Itadoptsfrequencyconversion,withstableperformance.Thismachine
alsoequipwithpaperanti-curvedevicethancanmakethelaminatedpaper
smoothwithoutcurving.Thehydraulicsystemadoptsautomaticoilsupplying
system, easyoperationwithoutneedadjusting, alsoeasytomaintain.
ThismachinemainlytakesBOPPfilmasitsmaterialand compound with
paperautomatically.Afterlaminating,thelaminatedproductswillbebrightin

anddampproof.Soit iswidelyappliedincoversofbooksandperiodicals, maps,
packagingboxes. Thismachinehasadvantagesofbigworkingpressure,fast
temperaturerising,highspeed,lownoiseandevenrunning.Andcomparedwith
traditionallamination,therearenodefectsofsnowspotandfloginlaminated
