Leak-Proof Lip Gloss Tubes - Causes & Solutions | Shantou Lichai Cosmetic Packaging Co.,Limited
| ⚠️ Why Leaks Happen |
✅ How We Solve It |
|
Inconsistent cap seal pressure
Poorly cut threads or cap material softening over time loosens the seal.
|
One-piece cap with molded sealing ribs
Creates consistent contact pressure around the tube neck.
|
|
Improper wiper fit
Too loose lets product seep through. Too tight causes dragging and edge leaks.
|
Custom wiper hardness & diameter
Soft wipers for thin oils. Firm wipers for thick glosses.
|
|
Tube neck deformation
Thin walls or low-quality materials warp under heat or pressure.
|
PETG dimensional stability
Maintains shape from cold warehouses to hot shipping containers.
|
|
Formula-material reaction
Oils and solvents cause certain plastics to crack or swell.
|
PETG chemical resistance
Safe with common lip gloss ingredients. No cracking or swelling.
|
📌 Bottom Line: Choose the right material + maintain precision tolerances = no leaks.
