A reusable tin provides the outer case, while the inner pouch is specified around tablet contact, closure and moisture-barrier requirements. Tin dimensions should follow the filled pouch, including seal margins, zipper thickness and folds, rather than the loose tablet volume alone. Heat-sealed pouches, resealable formats or smaller portion packs can be evaluated according to the intended filling process and customer routine. Tablet capacity and storage performance depend on the actual formulation, pouch construction and complete pack; both need confirmation before launch. Jinyu’s custom tin projects start from 5,000 pieces, with pouch supply, artwork, material documentation and packing responsibilities agreed in the quotation.
