Get to know PP Plastic Packaging: How Safe Is It for Food and Consumers?
In today’s world, where consumers are increasingly concerned about food safety and packaging quality, PP plastic (Polypropylene) has become one of the most widely used materials in the food industry. From yogurt cups and food containers to lids for both hot and cold drinks — why is PP so popular, and how safe is it really?
What is PP Plastic?
Polypropylene (PP) is a type of thermoplastic polymer known for being semi-rigid, slightly flexible, and naturally translucent. It offers high heat resistance (about 100–120°C) and does not release harmful chemicals when in contact with food or heat.
Is It Safe?
PP plastic is certified by multiple safety standards, such as:
- TISI (Thai Industrial Standards Institute)
- FDA (U.S. Food and Drug Administration)
- BPA-Free – Free from Bisphenol A, a chemical known to disrupt hormonal balance
These certifications ensure that PP packaging is safe for direct contact with food without posing health risks to consumers.
Heat and Cold Resistant
PP is ideal for packaging that must withstand a wide range of temperatures, including:
- Microwaveable containers
- Freezer-safe boxes
- Hot food containers like soup bowls or noodle cups
Eco-Friendly Choice
While it’s still a type of plastic, PP is recyclable (Resin ID code #5) and has a long lifespan, making it a better alternative to single-use plastics. Choosing PP helps reduce waste and supports more sustainable packaging practices.
