winlong adhesive manufacturer-glue for cardboard boxes, hot melt adhesive for automatic box sealing Case & Carton Sealing Material Options Selecting the right material for your case and carton sealing application is an important decision. While this may seem insignificant compared to other decisions, the wrong choice could be disastrous. Making sure your products are sealed properly to reinforce quality and handle transportation logistics will have a major impact on the sustainability of your business. The two main material choices for case and carton sealing applications are hot melt adhesive and adhesive tape. Hot melt adhesive is a synthetic resin that liquefies when heated and is applied using a small, handheld applicator or a large automated system with multiple automatic applicators. Adhesive tape is a pressure sensitive plastic or nylon-reinforced filament where a polymer is usually the main adhesive element. Since both materials are viable solutions for case and carton sealing and end-of-line packaging operations, understanding the advantages and disadvantages of each can assist plant managers who are looking for the best solution.
