Global beauty brands are promoting plastic reduction and sustainable packaging upgrading. Recycled cartons, lightweight bottle boxes and paper alternative inner trays are increasingly applied to serums, creams, makeup and other products. The change of packaging materials forces corresponding technical adjustments to the cosmetic cartoning machine. The first demand is the adaptation to low-stiffness recycled paper packaging boxes. A large number of brands have begun to use recycled paper and lightweight cardboard as outer packaging, which have lower hardness and are easier to wrinkle and tear under stress. Old-fashioned cartoning machines with fixed suction force and folding pressure are prone to carton tearing, crease deviation and box forming failure when processing such cartons.
The second technical upgrade demand comes from the positioning accuracy improvement brought by paper alternative inner trays. To reduce plastic use, many beauty gift boxes abandon plastic inner trays and use molded pulp or folded cardboard to fix perfume bottles, makeup palettes and serum bottles. Paper inner trays have larger dimensional tolerances than plastic ones and are more brittle. This puts forward higher standards for the feeding positioning and pushing accuracy of the cosmetic cartoning machine. It is necessary to optimize the photoelectric recognition system and flexible pushing mechanism to avoid paper tray fragmentation and skewed product placement during assembly, so as to realize fully automatic production of gift boxes without manual auxiliary placement of inner liners.
Third, the popularization of self-locking socket cartons puts forward higher standards for folding accuracy. Many beauty brands abandon plastic sealing tape and use socket self-locking cartons to close the box body, so as to reduce plastic consumables. Self-locking cartons are very sensitive to crease position accuracy; minor deviations will cause the socket to fail to lock and the box cover to pop open by itself. This requires the folding mechanism of the equipment to further improve the servo control accuracy, ensuring that each carton has a consistent bending position and angle, and the self-locking buckle can be stably fastened. In addition, lightweight packaging also brings challenges to conveying stability. The weight-reduced carton is lighter overall, and it is prone to offset and drift during high-speed conveying, which requires optimized guide limit structure and matched conveying speed logic.
Beauty factories that take the above trends into consideration at the stage of equipment procurement or old machine transformation can better undertake orders from brands focusing on sustainable concepts and adapt to the future development trend of beauty packaging. With the continuous deepening of the sustainable concept in the beauty industry, the material adaptability of packaging equipment will become an increasingly important competitive indicator.
