Takeout kraft bags, snack outer cartons and frozen food packaging demand eco-friendly production and reliable adhesion. Atmospheric cold plasma is solvent-free and food-safe, ideal for food packaging inline pretreatment
.Kraft paper with lamination often has poor glue anchoring. Plasma removes surface grease and coating inertness, allowing flexible cold glue bonding to bear repeated folding and heavy carrying. The equipment runs stably with kraft bag production line speed up to 45m/min, supporting continuous mass production of shopping bags and catering packaging.No chemical additives or dust are produced during plasma processing, fully compliant with international food contact regulations. It reduces carton/bag splitting during delivery, and enables factories to use economical water-based glue rather than high-cost food adhesive.
