As consumer demand for safer, reusable and eco-friendly food containers grows, material choice matters more than ever. Ecozen and PETG are two leading copolyesters — but they are designed for different priorities. This guide helps you pick the right material for your product line.
What is Ecozen?
Ecozen is a bio-based copolyesterdeveloped by SK Chemicals. It features excellent heat resistance, glass-like clarity, and bio-content derived from plant feedstocks. Ecozen is widely used for premium lunch boxes, baby cups, and reusable food containers that require dishwasher and microwave safety.
What is PETG?
PETG is a petroleum-based copolyester known for its clarity, impact resistance and cost-efficiency. It is commonly used in packaging, cosmetic containers and some food-contact applications — but it has lower heat tolerance compared with Ecozen.
Key Differences: Ecozen vs PETG
Heat Resistance
Ecozen: withstanding -20–100°C (depending on grade) — dishwasher & microwave safe.
PETG: softens 70°C — not suitable for hot-fill or microwaving.
Sustainability
Ecozen: contains bio-based content, reduces fossil feedstock use.
PETG: fully petroleum-based.
Durability & Longevity
Ecozen resists cracking and deformation under repeated heating; PETG is durable but less heat-stable long-term.
Appearance
Both are clearly visible; Ecozen often exhibits a slightly warm, premium sheen with a glass-like transparency, making it highly favored by high-end brands.
