Are these liners heat resistant for hot filling applications?
These closures include a lined insert, but child‑resistant push‑and‑turn closures are generally not recommended for hot fill applications. High heat can affect both the plastic closure and liner performance, which may impact seal integrity. For hot fill processes, we recommend selecting closures specifically designed for heat exposure and testing with your exact process before placing a large order.
