1. Standard UK Candle Vessel Sizes & Internal Clearance
Standard UK candle glasses typically range from Votive (9cl), Classic Tumbler (20cl – 30cl / 75mm × 90mm), up to 3-Wick Bowls (50cl+). Always add 2mm–3mm internal clearance around the vessel diameter to accommodate manufacturing glass tolerances and prevent friction scuffing during transit.
2. Crash-Lock Auto Bottom vs Reverse Tuck End
Because candle jars carry significant weight, we strongly recommend Crash-Lock Auto Bottom boxes (also called auto-lock base). The base automatically snaps shut when pushed open and supports heavy glass securely without the risk of the bottom opening under weight. For luxury gifting ranges, two-piece lid-and-base rigid boxes offer the ultimate premium reveal.
3. CLP Regulatory Compliance & Warning Panels
UK candle packaging must accommodate mandatory CLP (Classification, Labelling and Packaging) regulations, including hazard pictograms, allergen declarations, and safety burning instructions. We ensure your custom dieline reserves dedicated base or rear panels for clear, fully compliant labelling.
