According to the inner layer AL/PP composite method, the Aluminum Laminated Film process can be divided into two types: thermal method and dry method. The advantages of the dry process are that the product has fewer appearance defects, good deep drawing performance, low equipment investment threshold, simple process and easy to master, but limited by PP glue, its interlayer peeling force and electrolyte resistance are relatively weak; The advantage of the method is that it has excellent electrolyte resistance and water resistance. The disadvantage is that the residual thermal stress and the extrusion stress between the rollers during the high-temperature and high-pressure molding process result in the relative deterioration of its appearance and deep-drawing performance.

Mingguan Lithium  Film has made technological innovations in raw materials and manufacturing processes, creatively developed dry-heat composite process technology, and took into account the advantages of thermal method in terms of electrolyte resistance and water resistance, making aluminum-plastic film forming in deep drawing. , Appearance, electrolyte resistance and water resistance and other comprehensive performance has been improved.

Aluminum Laminated Film  products have many performance advantages such as excellent deep drawing performance, good electrolyte resistance, good product appearance, good insulation, strong heat resistance, high heat seal strength, humidity and heat aging resistance, and high and low temperature resistance.
