2 oz 53 MM Emerald Thick Wall Round Base SAN Jar

For Part 121320, the central question is how the jar packaging format behaves in the assembled package. Jar selection should balance filling access with closure weight, decoration area, and the product’s expected use rate. Likely development programs include skin-care creams, body butter, hair treatments, wellness powders, and supplements. Commercial approval should reflect filled-package testing under realistic processing and distribution conditions. This keeps sourcing decisions tied to measurable package requirements.
