H.B. Fuller’s model M450 Liquamelt case erector from A-B-C Packaging Machine Corp. uses a soy-based adhesive that offers a sustainable alternative to traditional petroleum-based hot melt. The M450 is designed to achieve 50 cases per minute, according to the company. Liquamelt is liquid at ambient temperatures to eliminate the need for heated premelt tanks and heated hoses. Features include a walking beam mechanical case transfer and a servo-operated sealing ram.
