Harpak-ULMA: Vacuum sealing technology

Packages are sealed only on one end and are prepared to be transferred to the buffering belt of the vacuum chamber with the open end facing both seal bars on the vacuum chamber. A 90-degree transfer system pairs the packages to the buffering belt of the vacuum chamber so that both seal bars can be utilized. If the products are not small enough to be paired, an auto-detect system will load the product as a single item. This automated system increases productivity and reduces labor costs.
