Shanghai Tangke New Materials：25KG Aluminum Composite bag

The 25KG Aluminum Composite bag launched by Shanghai Tangke not only inherits the characteristics ofaluminum-plastic composite materials such as high barrier property, puncture resistance, moisture resistance and light protection, but also achieves full-range adaptation to different material packaging scenarios through four distinct structural forms—conventional type, M-fold design, heat-sealed square bottom and valve port configuration.

In the product display, it can be seen that each of the four structures has unique features: the conventional type is suitable for general-purpose material packaging; the M-fold structure enhances the three-dimensional stability of the bag, facilitating stacking, storage and transportation; the heat-sealed square bottom design improves load-bearing balance and standing stability; while the valve port structure enables dust-free filling and efficient sealing, making it particularly suitable for the airtight packaging of powder and granular materials.

This Aluminum composite bag adopts a PE/AL/PA/PE multi-layer co-extrusion composite process with a thickness of 0.15-0.18mm, and can be safely used within a load range of 10-50KG. Its milky white base material combined with customizable printing not only meets the needs of brand visual communication, but also has excellent product information labeling and traceability functions.

Currently, this bag type has been widely used in various fields such as chemical raw materials, pharmaceutical intermediates, food additives, engineering plastics and electronic materials, providing enterprises with an integrated solution from packaging structure to functional realization. In the future, with the deepening of intelligent manufacturing and green packaging concepts, such packaging products featuring practicality, safety and customization are expected to further promote the development of industrial packaging towards high efficiency and refinement.
