5 Square Meter Soft Bag Battery Special Aluminum Plastic Film Polymer Lithium Battery Shell for Aluminum Plastic Composite Film (Thickness: 113um, 1)

Product Description1. Inside the mold cavity of the aluminum plastic film, there are strictly prohibiting fine particles of dust. Before the operation, the dust -free paper/dust -free cloth dipped in water -free ethanol is completely cleaned.

2. After the aluminum -plastic film is formed, the four corners are smooth and round, and the thinnest is ≥ 60%of the original film.

3. Thermal seal temperature (reference): The temperature of the top side package (polar ear end) temperature is 180-210 °C, the packaging time is 2.5-5s, the pressure is 0.3-0.6MPa, and the packaging temperature is 175-195 °C.

4. Thermal seal effect detection: Method 1: Use a pointed dry score to measure the seal area. Extreme ear glue thickness +2 *PP layer thickness) *85%. The thickness of the side seal is: 2 *ON layer thickness+2 *alize thickness+2 *pp *85%. Method 2: Cut the sealing area with a width of 15mm, and use the stripping tester to peel away. Visual inspection of the PP layer of the aluminum plastic film is milky white, and the peeling strength is ≥30n/ 15mm.
