A Factory That Sells Directly, and Says So
Tianzhen (TZ Battery Film) runs a modern production base and a trading hub. We quote, print and ship within one system, which is why lead times and pricing hold up.
Battery Film Manufacturing Experts
Tianzhen was founded in Foshan in 2021, focused on battery heat shrink and insulation film for lithium packs, today operating a modern production base and trading center.
Most of our customers come to us after a bad experience with a trading company: a price that moved, a lead time that slipped, a structure that did not match the spec. Our answer is to make the spec explicit — film structure, gauge, print method and certificate — on every quotation.
