Polypropylene plastic, or PP, is now widely used in various household and industrial applications. From food containers and household tools to product packaging, PP plastic is well-known for its durability and safety.
This article will thoroughly explain what PP plastic is, its characteristics, and how it's used in everyday life. You’ll also get to know other types of plastic that are equally important in the packaging and industrial world.
What Is PP Plastic?
PP plastic (Polypropylene) is a type of thermoplastic that is lightweight, strong, heat-resistant, and widely used in both industrial and household products. This material is food-safe and easy to recycle.
PP Plastic Recycling Code: Symbol, Number, and Meaning
PP plastic is identified with recycling code number 5, represented by a triangular recycling symbol with the number 5 and the initials “PP.” This code indicates that the material is recyclable and relatively safe for food and beverage packaging.
Details of the PP plastic recycling code:
- Number: 5
- Symbol: Recycling triangle
- Name: PP (Polypropylene)
Commonly Found Examples of PP Plastic
PP plastic is widely used in daily life due to its lightweight, strength, and heat resistance. You can find PP plastic in various household products, food packaging, and even medical equipment.
Here are some common examples of PP plastic:

Differences Between PP and PE Plastics
PP and PE are two types of plastics frequently used in industry, but they have different characteristics:
- Composition and Structure
- PP has a more rigid and crystalline structure, making it stronger
- PE is more flexible and softer, especially at low temperatures
- Heat Resistance
- PP resists heat up to ±120°C, suitable for hot food containers
- PE only resists heat up to ±80°C, better for low-temperature use
- Texture and Appearance
- PP is usually transparent to semi-transparent and more rigid
- PE appears milky (white opaque) and is more flexible
- Common Uses
- PP examples: Bottle caps, microwave food containers, buckets, medicine bottles
- PE examples: Plastic bags, plastic wrap, liquid soap bottles
