Polypropylene (PP)

Polypropylene, commonly abbreviated as PP, is a thermoplastic polymer, known for its high strength and durability. PP is a plastic with a very high melting point (160-170 degrees celcius), a low density, and a high tensile strength. High thermal resistance also allows polypropylene to be used in applications with a lot of heat, without deforming. 

Polypropylene is also a plastic with high chemical resistance, making it an ideal plastic to use in applications that include acids, bases, and solvents. Because this plastic is also UV resistant, it can be used indoors and outdoors. 

Manufacturing from Polypropylene

In order to work with PP in the manufacturing process, it can be melted down via the process of extrusion and moulding. The most common form of moulding is injection moulding, which can be used for products such as cups, bowls, shopping baskets, etc. 

Injection moulding is where PP pellets are melted down and injected into a mould. Once the product has cooled and solidified, the mould is opened and the finished product is then ejected. 

Extrusion is similar to injection moulding, but instead of injecting into a mould after the PP pellets have melted, they are pushed through a die to create a continuous shape. After the product has cooled, the resulting shape can be cut down to the desired length.

Many different additives and surface treatments can be added to polypropylene to give it desired product characteristics. This includes additives that make a PP product resistant to dust and dirt or surface treatments that promote adhesion of paint and printing inks.

How Can Polypropylene be Used?

  • Packaging is often made of Polypropylene due to its somtimes transparent nature, durability, strength, and resistance to moisture. PP can be used for to-go containers for food and beverages, for bags, films, etc. 
  • Textiles can also be composed of PP. This application includes textiles such as carpets, furniture coverings, totes, and clothing. Polypropylene also has lightweight and hypoallergenic properties making it a fantastic wool substitute. 
  • Consumer products is another aread where Polypropylene is used. Products such as toys, furniture, and appliances benefits from the versatile and affordable traits of PP.

Polypropylene is a very versatile material that can be used for a wide rang of products. It is an ideal material for products such as the PP non woven bag collections: Vienna, BerlinLisbon, Frankfurt, Moscow, and Munich.

PP can also be recycled, making it a good candidate for our sustainable lines of reusable containers. These to-go containers include reusable To-Go Bowls and To-Go Cups. Check out our store for more ideas on resuable packaging and bags »

Advantages of Polypropylene

  • Chemical, Heat, and UV Resistant
  • Strong and Durable
  • Lightweight
  • Versatile with a Low Cost
  • Recyclable

There are many advantage to using PP in the manufacturing process. Its strength and durablitiy allows products made of PP resistant to wear and tear.

Being UV and heat resistant is also ideal because it allows products to be used indoors and outdoors with deforming.

PP is a material that is resistant to impact, puncture and abrasion. It is also low density, meaning it is lightweight. This mean a product can be strong, while also being easy to move and transport.

This material is recyclable, which can also make it a sustainable option to work with.
