Plastic Polyester Film By Wonder Pack

Plastic Polyester Film base is a transparent substrate which acts as a support medium for the photosensitive emulsion that lies atop it. Despite the numerous layers and coatings associated with the emulsion layer, the base generally accounts for the vast majority of the thickness of any given film stock. Historically there have been three major types of film base in use: cellulose nitrate, cellulose acetate (cellulose diacetate, cellulose acetate propionate, cellulose acetate butyrate, and cellulose triacetate), and polyethylene trephthalate polyester. It is mainly used for printing then it is to be laminated with other poly and hence it forwarded as customers demand.
