Primary packaging directly encloses products and protects them from external influences. Pharmaceutical and food products must be safely packed so that the sensitive products arrive at their destination undamaged. Primary packaging can be glued quickly and reliably with a precise hot melt adhesive application. This even includes small packing formats for chocolates, chewing gum, cough drops, and demanding packing materials such as recycling paper or OPP films.
Products in the food and pharmaceutical industries are sensitive. Thus, primary packaging must adequately protect chocolate bars, herbal candies, and similar from heat and scents. For this reason, even tiny articles are individually wrapped in PE films, OPP films, laminated films, paper, or cardboard. This places unique demands on the gluing of primary packaging:
With the Vision melter, Performa heated hose, and SpeedStar Compact hot-melt application head, you get the dream team for repeatable, high-precision adhesive application in your packaging process. These three interact optimally. In the end, every dot is at the right spot - every time. No matter how small your packaging or how demanding your adhesives and your packaging materials are.
But not only that. The three team players form an adhesive application system that noticeably improves the gluing process’s energy and operating cost balance.
The Vision melter controls the heating capacity via two temperature zones. It can thus melt even temperature-sensitive hot melt adhesives particularly gently and energy-efficiently. The fast-switching piston pump delivers the adhesive at constant pressure for a consistently uniform adhesive application. Vision achieves a system availability of more than 99 % and ensures high process reliability.
The Performa heated hose ensures that the adhesive neither overheats nor cools down uncontrollably at the connection points on its way from the melter to the application head. The adhesive retains its viscosity required for reliable gluing.
The SpeedStar Compact application head applies 0.5-millimeter dots and short beads to tiny primary packaging with high precision - and that at a switching cycle of 800 Hz.
SpeedStar Compact maintains this performance with repeatable accuracy over a service life of 500 million operating cycles, as the intelligent control detects and compensates for stroke changes via the automatic displacement control. The adhesive application remains precise, even under changing conditions such as adhesive temperature, viscosity, and mechanical wear.
