How PET and HDPE differ and which to choose for food, beverage, detergent and cosmetic packaging.
8 April 2026 4 min read
Most plastic bottles and containers are made from PET or HDPE. The right choice depends on what you are packing and how the product behaves.
PET
PET is clear, lightweight and a good barrier — common for beverages, water and food products where visibility matters.
HDPE
HDPE is opaque, tougher and more chemical-resistant — common for detergents, chemicals and jerry cans where durability matters more than clarity.
Other considerations
- Food-contact suitability where applicable
- Closure and neck compatibility
- Capacity and wall thickness
- Migration documentation where required
Key takeaways
- PET is clear and ideal for beverages and food
- HDPE is durable and chemical-resistant
- Match closures and necks to the bottle
- Confirm food-contact and migration documents
