Shrink tunnels

The co. introduces ConvectAir(TM) shrink tunnels for use with heavy LDPE films often found in shrink bundling. The ST-800, ST-830 and ST-830XL use a combination of convection heating, radiant heating and a minimal flow of recirculated air for faster shrinking of LDPE films at a lower overall peak temperature, the co says. The new tunnels can produce 60 to 70 packs/min, utilizing a chamber that is 5 ft long. The ST-800 offers an 18-in. conveyor width, and the ST-830 offers a 30-in. width, with both able to reach production speeds of up to 100 fpm. The three models are available with optional casters, flow direction and an exit-cooling fan unit and the co. says they're covered by a one-year, unlimited-cycle warranty.,
