Doyen launches high speed oral strip converting and packaging system

Doyen has launched an oral strip converting system that uses the company's HDW high speed four side seal packaging machine technology.

The oral strip unit converts bulk reels of the product with slitters and rotary cutters, transferring and spacing the product with an accurate vacuum transfer system.

The high-speed machine transfers the bulk oral strip from a large bulk reel, removes the release liner and slits the product into eight lanes. The lanes are separated through a guidance system which transfers the strips at almost zero tension, and at the correct pitch, to a rotary cutting station. The cutter and anvil work at differential speeds to the oral strip web, and the strips are cut, separated and accurately placed onto the open packaging with a vacuum anvil.

The foil-based pouch stock laminate is unwound from a single web split and turn unwind for dual registered print on the finished package. Following the split, the base web is directed to collect the product and the top web is introduced to complete the unsealed web. The pack is sealed with Doyen's HDW high-speed, high-dwell continuous motion platen sealing head. The head has multiple temperature and pressure zones to overcome the consistency and flatness problems associated with large platen systems. As they emerge from the HDW head the products are slit and cut to length.

The process is completed with a positive failsafe reject station controlled by the machine's integral quality system, which monitors the packages for missing product, joins in the packaging web, and loss of control of critical parameters.

The machine operates at 1,200 converted and packed products per minute.
