OYANG AUTOMATIC WINDOW CUTTING AND STRIP FILM LAMINATING UNIT (OPEN WINDOW) The OYANG Open Window (+W optional unit) is an integrated system that cuts an opening (window) of the desired size on the front or back of a bag during paper bag production from a roll, then covers the opening with a strip of transparent film (PP/PE), enabling the production of windowed paper bags (such as windowed bags for bread, croissants, or other baked goods).

- Seamless Inline Integration: Completes window cutting and film application in a single pass, eliminating the need for external window patching machines and intermediate stacking processes.
- Servo-Driven Cutting Roller: The window cutting unit features a custom alloy die roller that creates clean, precise window outlines on roll paper at high speed and with consistent performance.
- Synchronized Servo Speed Matching: Servo motors instantly synchronize the paper feed speed with the window-cutting die speed, ensuring accurate window positioning regardless of the production rate.
- Micron-Precision Film Patching: Based on dimensions entered via the touchscreen, the transparent film is applied to the cut window with ±0.5 mm accuracy using a vacuum transfer cylinder.
- Intelligent Film Length Calibration: The cutting pitch and film length are controlled from the digital panel, minimizing film waste for windows of different sizes.
- Automatic Rotary Glue Application: Features a leak-proof rotary glue disc system that automatically optimizes the amount of adhesive applied around the window edges according to the machine speed.
- Broad Film Material Compatibility: Reliably processes packaging-standard transparent films such as BOPP, PET, and PVC, as well as eco-friendly biodegradable packaging films.
- Photocell Control for Pre-Printed Materials: If the paper roll contains pre-printed graphics, integrated photocell sensors detect the print pattern and cut the window precisely in the center of the printed design.
- Wide Range of Supported Paper Weights: Delivers clean, stain-free processing across all thicknesses supported by the main machine, from lightweight papers used for bakery packaging to heavy kraft rolls used for luxury shopping bags.
- Flexible Modular Design: Depending on production requirements, it can be factory-installed as an equipment package on OYANG’s square-bottom packaging machines (B Series) or sharp V-bottom machine models (C Series).
