Drop Test for Lip Gloss Tubes - 1 Meter Height | Shantou Lichai Cosmetic Packaging Factory
Do your lip gloss tubes pass the drop test from 1 meter height?
PETG · 1.2mm wall thickness · Concrete floor · Filled with cap on
The short answer: Yes, our PETG lip gloss tubes pass the 1-meter drop test. But let me be specific about what that means.
We test filled tubes with caps on. Drop them onto a concrete floor from 1 meter. Different angles: straight up, straight down, on the side, on the cap. We check for cracks, leaks, and cap separation.
PETG passes where other materials fail. Acrylic shatters. Glass breaks. Cheap plastic cracks. PETG absorbs impact without breaking. The tube might scratch, but it will not crack or leak.
That said, drop test results depend on wall thickness. Our standard tube wall is 1.2mm. Thinner walls below 0.8mm may not pass. We can adjust thickness based on your needs.
One more thing: test with your actual formula inside. A tube filled with thick gloss behaves differently than an empty tube. We recommend you run your own drop test on samples before bulk order.
📋 Drop Test Conditions
- Height: 1 meter (3.3 feet)
- Surface: Concrete floor
- Tube state: Filled + cap on
- Angles tested: 4 directions
- Pass criteria: No cracks, no leaks, cap stays on
🔧 Wall Thickness Guide
- 1.2mm (standard) – Passes drop test
- 1.5mm – Extra durable, for premium lines
- Below 0.8mm – May not pass
- We adjust thickness per your request
- Thicker wall = heavier tube
| Material | 1-Meter Drop Test Result | Notes |
|---|---|---|
| PETG (1.2mm wall) | ✅ Passes | May scratch, but no crack, no leak |
| Acrylic | ❌ Shatters | Too brittle for drop applications |
| Standard plastic (thin wall) | ❌ Cracks | Below 0.8mm likely fails |
| Glass | ❌ Breaks | Not recommended for travel sizes |
⚠️ Two common mistakes buyers make:
Mistake #1: Testing empty tubes. A tube filled with product behaves differently. The formula can act as a cushion. But some formulas can also make the plastic brittle. Always test with your actual product inside.
Mistake #2: Assuming all PETG tubes are the same. Wall thickness varies a lot. Cheap tubes with 0.6mm wall thickness crack on first drop. Our standard is 1.2mm. We can go up to 1.5mm or thicker if needed.
💡 What actually works: Get samples. Fill them with your formula. Drop them yourself. Seeing the result with your own eyes is better than any certificate or promise. We will send you samples. You do the test. Then you decide.
📦 Need stronger tubes? We offer thick-wall PETG up to 1.8mm for brands shipping to rough markets or selling to clumsy customers. Costs more. Works better. Tell us your drop test target and we will recommend the right wall thickness.
