Case studies on food-contact documentation, aqueous cups, barrier coatings, and folder-gluer qualifications for food, pharma, and cosmetic packaging.
CONSUMER PACKAGING A beverage packer replaced a char-prone hot melt with a metallocene case-sealing route that kept nozzles cleaner over a six-month qualification window, improved adhesive mileage, and held fast set on recycled corrugated.
