Customized designs can be made based on customer needs, including raw material formulation, film thickness, width, length, transparency, color, and printing. For example, companies can customize film rolls of varying specifications to suit specific packaging equipment; adjust the type and ratio of plasticizers to achieve the desired flexibility and conformability; and achieve single- or multi-color printing, allowing brand logos, product information, or warning graphics to be printed directly onto the film, enhancing the packaging’s aesthetics and recognition.
