Non-IBC Layflat Width Control For Blown Film Lines
Managing Your Resin Costs Efficiently
The majority of non-IBC die applications today currently have no automated layflat width control capability which means there is no effective way of controlling resin costs, or what we like to call Runaway Resin.
Runaway resin is plastic that leaves your facility without generating a single penny of revenue, and worse yet, you must still pay to process that resin. The DRJ LF-Sizer helps control your resin costs by providing a fast, accurate and user-friendly layflat control system for non-IBC applications.
By measuring the bubble soon after the frost line, the system can achieve the proper bubble size without waiting for the film to pass through the top nip rollers and can perform even when running gusseted film. This greatly improves width control efficiency. The LFSizer provides the operator with a simple color touch screen interface that allows entry of the target layflat width.
A special air diffuser is also supplied to ensure rapid inflation does not unlock the bubble from the air ring
during start-up. The separate 3 speed inflation control box has adjustable fast fill, slow fill and exhaust modes
of operation. Once the bubble is on size, the LF-Sizer maintains that size at all times. For size changes, the operator simply enters a new target and the bubble is sized automatically.
