Key Considerations When Using a PE Container

1. Formula Compatibility: This is the primary reason to choose PE. If your lip gloss has a high concentration of certain oils, solvents, or fragrance oils, PE's resistance makes it a safe choice to prevent the tube from becoming brittle and cracking over time.

2. Clarity Requirements: If you want the container to be crystal clear to show off the exact color of the gloss, PP might be a better option. If a slight translucency is acceptable, clarified PE will work.

3. Fill Volume and Viscosity: Like all twist-up tubes, they work best with low to medium viscosity products. The platform must be able to push the product smoothly up the tube. Very thick products can stall the mechanism.

4. Post-Consumer Recycled (PCR) Content: PE is one of the most common plastics for incorporating PCR (Post-Consumer Resin). Many brands now offer tubes made with a percentage of recycled PE, which is a significant sustainability advantage.

In summary, a PE lip gloss container is a reliable, cost-effective, and highly compatible workhorse of the cosmetics industry. Its superior resistance to the oily ingredients in lip gloss makes it a technically sound and very popular choice, even if it sacrifices a small degree of clarity and rigidity compared to Polypropylene.
