Delta ST Star-sealed T-shirt bags

The Delta ST enables production of star-sealed T-shirt bags on roll in 1 or 2 lanes. It is also possible to produce conventional T-shirt bags, wave-top bags, side sealed, bottom sealed and star-sealed bags in a Delta ST line. It is available for production in-line with an extruder or out-of-line, from an unwinder. The configuration is identical to the Delta T, for production of conventional T-shirt bags, with addition of the “star-sealed kit”. The “star-sealed kit” is a patented concept that allows production of star-sealed and conventional T-shirt bags in the same line. The configuration includes a Delta sealing module, a punching module for cutting out the handles of the T-shirt bag and an extraction module for removal of the cut-out waste. The cutting plates in the punching module are fixed to a magnetic roller and can be changed to another cutting pattern within a few seconds. A patented concept makes it possible for the shaped cut-out to be done before perforation and sealing. This ensures that cutting is done in a zone with precise tension control, giving a clean cut and accurate positioning of the cut-out, minimizing skirt variation. All bag types can be wound conventionally or interleaved. It is possible to integrate automatic roll handling/packaging to your Delta line.
