PET vs PETG for Cosmetic Packaging
A practical comparison to help you choose the right material
Published: May 1, 2026 · Reading time: 5 min
Quick Answer
Choose PET for cost-effective, clear packaging for standard products (lotions, toners, body care). Choose PETG for premium products that need extra durability and chemical resistance (serums, essential oils, active ingredient formulations).

When to Choose PET
PET (Polyethylene Terephthalate) is the most widely used plastic in cosmetic packaging. It offers exceptional clarity—almost as clear as glass—at a fraction of the cost. PET is the go-to choice for:
- Standard lotion and toner bottles
- Clear jars for creams and balms
- Body care and hair care packaging
- Products with neutral pH formulations
- Budget-conscious brand launches
PET is lightweight, widely recyclable, and available with FDA certification. It's an excellent choice for brands looking to balance quality with cost.
When to Choose PETG
PETG (PET modified with Glycol) adds glycol during production, which gives it superior impact resistance and chemical resistance compared to standard PET. PETG is ideal for:
- Premium serum bottles with active ingredients
- Essential oil packaging
- Products with alcohol or aggressive solvents
- High-end skincare lines
- Products requiring extra durability during shipping
PETG's superior durability means fewer breakages during filling, shipping, and daily use—making it a cost-effective choice for premium products despite the slightly higher material cost.
Frequently Asked Questions
Can PET and PETG be recycled together?
No. PET and PETG should be separated during recycling. PETG has a different chemical composition that can contaminate PET recycling streams. Check local recycling guidelines for proper disposal.
Which material is better for hot-fill products?
Neither PET nor PETG is ideal for hot-fill (above 70°C / 158°F). For hot-fill applications, consider PP or glass instead.
Does PETG cost significantly more than PET?
PETG typically costs 15-30% more than PET in raw material cost. However, the total cost difference per finished bottle is often smaller, and the reduced breakage rate can offset the higher material cost.
