The Newlong WATS is an industrial bag sealing machine designed to seal kraft paper bags using water-activated tape instead of traditional heat sealing methods. The system folds the bag top, applies adhesive tape activated by water, and compresses the seal for a secure closure.

Water-activated tape contains a starch-based adhesive that becomes tacky when exposed to water. The WATS system moistens the tape during application, allowing it to bond tightly to the folded kraft bag surface without requiring heat. Once applied and pressed, the tape creates a durable, reliable seal.

The WATS system reduces energy consumption by eliminating the need for heat-sealing elements. Lower energy usage contributes to reduced CO₂ emissions and improved sustainability for packaging operations. Additionally, water-activated tape is commonly used with paper-based packaging systems, supporting environmentally conscious packaging initiatives.

No. Unlike conventional heat sealers, the Newlong WATS operates without a heat source. The sealing process relies on water activation rather than thermal bonding, helping reduce electrical demand, heat generation, and maintenance associated with heating components.

Water-activated tape sealing offers several advantages, including lower energy consumption, reduced operating costs, decreased CO₂ emissions, and reliable seal performance on kraft paper bags. Because the system does not rely on heat, it can also improve operator safety and reduce wear on sealing components while maintaining strong package integrity.
