Douglas Gives You More With Contour Shrink Wrap Systems
More operational advantages, more consumer appeal, more of everything you need to stay ahead of the pack. The Contour Series offers a full spectrum of innovative features that maximize speed and easily accommodate large size ranges and pack-patterns for the food and beverage industries.
Contour 30/50 Features
- Clear or printed film wrapping of trayed product
- Available as a standalone unit or integrated with a tray packer (T-series)
- Simple and repeatable changeovers
- Single or dual spindle side film stands available for easy film loading and splicing
- Flexible servo driven wrapping wand provides exceptional film control and accurate film placement
- Revolutionary patented heat tunnel uses advanced heat and airflow management, delivering tightly wrapped
The Douglas Contour® heat tunnel is designed with the aesthetics of your product in mind. Whether your application calls for single or multiple lane production, unprecedented heat and airflow management ensures minimal graphic distortion, consistent bull’s-eyes and a tighter, more durable wrap. Enhanced tunnel operations significantly reduce noise and exterior heat temperatures, contributing to a quieter, cooler plant environment.
The heat system is designed so that the air supplied to the distribution system is perfectly uniform, eliminating film distortion due to hot or cold pockets. The Contour continuously recycles the air as it cools, decreasing the amount of energy required to reach operating temperature. A well insulated heat tunnel minimizes heat loss, which also maintains a safe outer surface temperature.
At the heart of this innovation is a combination of design features, which result in “laminar” airflow, rather than “turbulent” airflow, which most shrink systems use today. Unlike turbulent airflow, which causes a multitude of shrinking inconsistencies, our proprietary laminar design precisely balances the heated air, perfectly “coating” the film from every direction, shrinking and sealing the film in an even, predictable manner.
Evenly heated air passing through the conveyor web contacts the film under the product resulting in consistent “air weld” of the film lap seam. Tunnel chain temperature and airflow are precisely adjusted through product specific recipe-driven changeovers, optimizing performance. Poor lap sealing due to insufficient heat or holes melted in the seams due to overheating are eliminated, resulting in strong and even seams that hold up to the rigors of distribution and stocking operations.
The wrapping wand uses quick change circular, elliptical, or trapezoid wand paths, depending on product and size range. This results in increased film control and accurate film placement. More benefits include a large size range, the ability to accept randomly spaced products, and fewer parts to maintain.
