Specification Brand : FUWARMTH BulletPoint1 : Aluminum -plastic composite film is a composite material composed of the outer nylon layer (ON layer), the middle aluminum foil layer (AL layer), and the inner layer heat seal (PP layer). BulletPoint2 : Aluminum -plastic film is a key material for soft packaging lithium battery cell packaging. After the single -piece battery is assembled, the battery is sealing with aluminum plastic film, and the aluminum -plastic film plays a role in protecting the content. BulletPoint3 : Compared with packaging materials such as steel shells, aluminum shells, or plastic, aluminum -plastic films have advantages such as light quality, thin thickness, and flexible appearance design. They are widely used in many fields such as 3C consumer electronics, power batteries, and energy storage. BulletPoint4 : Select the specifications of the aluminum plastic film according to the thickness of the battery design: the thickness of the battery ≤3.5mm, select 88um aluminum plastic film; the battery single pit ≤5.0mm/dual pits <8.0mm, select 113um aluminum plastic film; Aluminum plastic film. BulletPoint5 : Aluminum plastic film: 300 mm width ExternallyAssignedProductIdentifier1 : 0751501179237 ExternallyAssignedProductIdentifier2 : 751501179237 ItemName : 5 Square Meter Soft Bag Battery Special Aluminum Plastic Film Polymer Lithium Battery Shell for Aluminum Plastic Composite Film (Thickness: 113um, 1) ItemPackageQuantity : 1 ItemTypeKeyword : plastic-film Manufacturer : FUWARMTH Material : aluminum plastic composite film NumberOfItems : 1 PartNumber : lithium battery aluminum plastic film ProductDescription : 1. 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.
