Integrated Printing Function
Equipped with an in-line printing unit, the machine allows for multi-color printing directly on the paper before forming. It delivers sharp, accurate results, reducing manual handling and eliminating the need for secondary alignment, which significantly boosts overall production efficiency. It also supports water-based ink, making it suitable for food-grade packaging with high standards of safety and environmental compliance—ideal for brands focused on visual presentation.
Flat Rope Handle Unit
The machine features an automatic flat rope handle making and pasting system, integrating handle application seamlessly into the bag-making process. This strengthens the bond between handle and bag body while simplifying workflow. It is especially suited for paper bags used in fashion, gifts, and other scenarios where carrying functionality is key. The system supports multiple size and material configurations to accommodate various bag types.
Internal Handle Folding Feature
The machine supports automatic folding of handles inside the bag body. This allows finished bags to be neatly stacked and folded, significantly reducing their volume and optimizing storage and logistics efficiency. The design is particularly beneficial for businesses with high shipping frequency and fast inventory turnover, such as chain retail stores and food delivery platforms—helping customers reduce supply chain costs effectively.
