OPAQUE WHITE BOPET FILM FOR TAG AND GRAPHIC PRINTING
The film of CY11 is type of opaque white film, with matte or glossy surface , which owning excellent electrical insulating performance and compound machining performance,one or both sides corona treated for ink and adhesive .Can be used for screen printing, inkjet printing,solar backsheet ,steel labels etc.
Film can be supplied in Rolls , sheeting service available upon request.the surface is smooth ,should not be wrinkles,rent , particle ,bubble , pinhole and foreigh mateere ,film should be neat without damage.
The thickness should be determined by the parties , selection of nominal thickness : 125um,150μm,188μm,250μm,300μm,350μm
The width is determined by parties, otherwise recommend 1000mm.The width of the film(excluding roll )shall conform to the provisions in Table 1,while cutting the film.
