Features of product:

The use of advanced and reliable thermal process production

Compared with the dry process, the compound of CPP / AL is not bonded by adhesive, and has excellent electrolyte resistance performance, durability and resistance to high and low temperature performance and ensuring the deep drawing and good insulation properties. In addition to meet the needs in civilian areas, it has more obvious advantages in durable, power-driven or energy storage lithium application.

Excellent heat sealing strength 

After several previous experimental verification, our aluminium laminated film owns good applicability for all kinds of tabs. It can be seen from the chart that with the increase of heat sealing temperature, the heat sealing strength basically has an increasing trend. Especially above 180 ℃, the heat sealing strength can be reached 75N/15mm. Temperature reaches between 190-215 ℃, heat Seal strength maintained above 85 N/15mm. When temperature is between 195-215 ℃, it is more than 90 N/15mm. Our aluminium laminated film maintains a high heat sealing strength in a wide temperature range which is quite favorable for the battery processing and durable usage.
