From the inception Carton Window Films Ltd core business was slitting products such as PET (Polyester), and other substrates for many applications for the carton industry. Although there are many types of films which are used in the carton industry, polyester film is the ideal product for window patching. Not only does polyester offer excellent clarity whether it be two side chemically treated or have a special coating such as anti-mist, it also offers great stiffness and flat surface which allow patching machines to patch at a higher rate when compared to other films. We work closely with polyester manufacturers to ensure that all films that are purchased meet the highest quality standards, which is backed up with all the right accreditations and technical support.

We have built a strong working relationship with the major suppliers of polyester such as Mitsubishi Polyester Film and DuPont Teijin Films who are a key part to our business and with their expertise and knowledge we are able to offer our customers the best film to suit most window film applications.

Our Enviromex® range are available in 36, 50, 75, 100, 125 and 175microns. These films are two side chemically treated to ensure 100% fibre tear and work with Pafra and Henkel glues.

We offer polyester with anti-mist coating which is ideal for windowing cartons that are refrigerated.
