What Makes a Plastic Container Microwave Safe?
Microwave-safe containers are made from materials that:
-
Withstand high temperatures without warping or melting
-
Do not leach chemicals into food when heated
-
Maintain structural integrity during reheating
📌 Look for icons or labels like:
-
“Microwave Safe” (usually with a microwave symbol)
-
Material type: PP or CPET
-
BRC or SGS certification reports

Best Plastic Materials for Microwave Use
1. Polypropylene (PP)
-
Heat resistance: up to 120°C (248°F)
-
Most common for takeout meal trays, deli tubs, and sauce containers
-
Durable and leak-resistant
2. CPET (Crystallized Polyethylene Terephthalate)
-
Withstands up to 220°C (428°F)
-
Often used in oven-to-microwave meals
-
Strong rigidity, no distortion under heat
3. HDPE (Limited Use)
-
Short microwave sessions only
-
Common for semi-rigid lids and drink bottles
-
Less popular in meal prep due to lower heat resistance
Avoid materials like:
-
PS (Polystyrene) – prone to warping and chemical leaching
-
PVC (Polyvinyl Chloride) – contains chlorine, not microwave-safe
Safety Tips for Using Microwaveable Containers
-
✅ Vent before heating: Slightly open or unseal lids to prevent pressure build-up.
-
✅ Check temperature guidelines: Never use cold-use PET containers in microwaves.
-
✅ Avoid reheating oily or high-sugar foods in unsuitable plastics (they heat faster).
-
✅ Don’t reuse single-use containers multiple times, as plastic integrity degrades.
-
✅ Do not microwave with cling film in direct contact with food.
