FAQ

Q1: What does the "300# (73mm) Full-Aperture" specification mean for this easy-open end?

A: "300#" is an industry-standard size code corresponding to an inner diameter of approximately 73mm. "Full-Aperture" means that upon pulling the tab, the entire central metal panel detaches completely at the seam, creating a wide, unobstructed opening without leaving a narrow, overhanging rim.

Q2: Can these 300# tinplate round ends withstand hot-filling processes or high-temperature sterilization?

A: Our standard specifications easily handle conventional processing conditions. For demanding high-temperature sterilization lines (e.g., 121°C processing), Jianyida offers specialized high-performance sterilization-resistant coatings and thicker tinplate options. When requesting a quote, please provide your specific thermal sterilization process parameters.
