he OVL Series Automatic Overlap Shrink Wrapper is designed for medium- to high-speed bundling of individual products and multipacks using a single roll of shrink film. The film is automatically wrapped around the product group with an overlapping section before entering the shrink tunnel, eliminating the need for the transverse welding bar used on traditional sleeve wrappers.
The system can handle a wide variety of products and packaging formats, including PET and glass bottles, cans, jars, cartons, boxes, trays, containers and other packaged products. Products are automatically separated, grouped and positioned into the required pack pattern before wrapping.
The OVL Series can produce film-only bundles or incorporate a cardboard pad or tray for additional support, stability and package presentation. Pads or trays can be automatically fed and positioned with the product group before the wrapping process.
The single-roll design is suitable for both clear and printed shrink film, making the OVL particularly attractive for applications where the film also provides branding and retail presentation. Film control and registration systems can be incorporated to maintain the positioning of printed graphics around the finished pack.
Different product handling systems can be incorporated to create the required pack pattern, including single or multi-lane infeeds, product separation, grouping and collation systems. The machine can be supplied in standalone, straight inline or 90° right-angle configurations, providing flexibility for both new and existing production lines.
Once wrapped, the bundle passes through a shrink tunnel, where controlled temperature and airflow shrink the film around the product to create a stable finished pack. With production speeds of up to 25 packs per minute, depending on product dimensions, pack pattern and film characteristics, the OVL Series provides a flexible solution for a wide range of automatic shrink bundling applications.
