💡 QC Insight for Buyers

Sticker adhesion may seem minor, but it is the “first impression” of your product’s retail packaging. Since the root cause is often human error in semi-automated lines, request a “first-article inspection” for packaging specifically. Simply asking the supplier to perform a “rub test” on the stickers at the start of every shift can significantly reduce the batch-wide failure rate.
