Low-temperature drop testing is also essential. Plastics become brittle and their impact resistance decreases in low-temperature environments, so it is necessary to ensure that the product still has sufficient drop resistance in low-temperature environmen
In the entire canned food production chain, seal integrity is the core factor determining whether a product can be safely stored and consumed long-term.
The pepper seasoning spice jar is far more than a simple container; it's a miniature preservation device that integrates materials science, sealing engineering, and human-computer interaction.
