Forced air convection tunnels use large volumes of high velocity air to impart sufficient shrink energy to the film. For most products, this type of tunnel does an excellent job. Texwrap’s standard line of forced air tunnels have proven over years of use to be capable of producing excellent results with most packages. Digital temperature controls, high velocity fans, individual top and bottom controls of air direction and variable speed conveyors all contribute to produce outstanding shrink results. Texwrap offers diverse tunnels to meet unique product requirements, including: Single Chamber Tunnels / Double Chamber Tunnels / Triple Chamber Tunnels
