💡 QC Insight for Buyers

In packaging, “tight enough” is not a standard — it must be verifiable. A lid that is easy to remove indicates thread clearance, which means the product is vulnerable to leakage during transit.

When briefing your supplier, don’t just ask them to “close the lid well.” Explicitly request a torque test or a visual closure check as part of the pre-shipment inspection. This simple step eliminates the risk of leakage and protects your product from damage — one of the most common and preventable issues we catch during inspections.
