PHA is the core material for soft-pack lithium battery packaging, featuring excellent properties such as puncture resistance and impact resistance, which can protect other substrates, effectively resist accidental impacts, ensure battery safety, and enhance battery capacity. sPHA is a high-performance BOPA film specially developed for the aluminum-plastic film of black soft-pack lithium batteries using specific processes and special formulations for long-lasting plastics. It has excellent color uniformity, impact resistance, puncture resistance, and abrasion resistance, effectively reducing the processing steps for aluminum-plastic film manufacturers and improving yield. Application examples primarily focus on lithium battery aluminum-plastic packaging films, which are an important component of high-performance aluminum-plastic films, mainly used in fields such as 3C consumer electronics soft-pack batteries, power soft-pack batteries, and energy storage soft-pack batteries.
