1. What is PP (polypropylene) plastic material?
PP plastic, short for Polypropylene, is also known as a thermoplastic polymer, meaning it can be easily recycled and reused many times. Manufactured from propylene monomer, PP plastic is usually transparent white or light pink in color, odorless, tasteless, and non-toxic.
PP (polypropylene) plastic material is transparent white or light pink.
2. What are the characteristics of PP (polypropylene) plastic?
PP plastic possesses the following properties:
- Has a good gloss.
- Water-resistant and gas-reducing.
- Not easily oxidized or affected by other gases including steam or grease.
- High durability and heat resistance, temperature resistance up to 130 - 170 degrees.
- Does not adversely affect human health.
3. Common applications of PP (polypropylene) plastic in life
PP plastic is used in many fields, including:
- Packaging and packaging products with one or more layers to prevent water vapor and air permeability, create high gloss, and provide high printability.
- They are forming fibers, and processing large-weight cereal and food packaging.
- Household items such as food containers, water bottles, milk bottles,...
- Medical products and equipment such as bottles and syringes.
- The automotive and electronics industries also use this material.
PP plastic material symbol on product packaging.
To identify products made from PP plastic, you can look at the product packaging. The symbol of this material is an isosceles triangle with the number 5 inside which is often printed on the bottom of the product. This is also the basis for identification for you to choose good and safe plastic products to use in daily life.
