A WORKED EXAMPLE
Attractive appearance. Seal performance still needs proof.
A sample pack looks correct, but the brand also requires validated protection and readable lot coding. The packing trial checks those requirements before production approval. Appearance alone cannot establish shelf-life or tamper-evidence claims.
