Applications
Backed by our sophisticated production control and material technology, our laminated electrolytic tinplate features superior deep‑drawing formability, dual‑protection from tin coating and lamination film, as well as firm film adhesion and good anti‑corrosion & leakage‑resistant performance. Boasting clean and uniform surface plus consistent batch‑to‑batch quality, the material can skip extra internal coating for certain applications. It fits various deep‑processing procedures such as can‑making, stamping and bending, with customized specifications available.
For food‑contact packaging and industrial component applications alike, we deliver cost‑effective metal raw materials for global customers with strict quality control, helping downstream partners optimize production workflows and raise finished‑product yield.
FAQ
Q:What is laminated electrolytic tinplate (Laminated SPTE / ETP)?
A:Laminated ETP is electrolytic tinplate bonded with a thin PET or PP polymer film by heat lamination. The film replaces traditional liquid varnish to protect the steel substrate.
Q:What are the core advantages of laminated SPTE?
A:It delivers a pinhole-free protective barrier with superior corrosion resistance and flavor retention. The solvent-free lamination process eliminates VOCs, and the film stretches well during deep drawing without cracking.
Q:What applications is laminated ETP mainly used for?
A:It is widely manufactured into food cans, pet food cans, dry food containers and aerosol cans, especially ideal for packaging acidic and sulfur-sensitive food contents.
Q:What is the difference between laminated ETP and ordinary tinplate?
A:Standard tinplate depends on sprayed liquid lacquer for protection. Laminated SPTE uses solid polymer film, offering more stable barrier performance and skipping the coating curing step in production.
Q:What thickness and temper grades can you supply?
A:Available thickness ranges from 0.15 mm to 0.40 mm. Temper options include T2-T5 and DR7-DR9. Single-sided or double-sided PET/PP lamination is available upon request.
