Polypropylene Vs Polyethylene Which Is Better?

Summary: This explains the various differences between Polypropylene and Polyethylene.


Polyethylene and polypropylene are two of the world's most widely used polymers. Because they are both polymers, they have a lot of similarities, and it can be difficult to tell them apart. However, they each have a number of distinguishing qualities, and understanding them will make it easier for you to decide which one to utilise based on your requirements.


Polypropylene is a kind of plastic. For starters, polypropylene differs from polyethylene in that it can be moulded and, as a result, becomes malleable above a specific temperature. It will cool down and revert to its solid condition. Polypropylene is a versatile material that may be utilised not only as a structural plastic but also as a fibre. It also has a higher melting point than polyethylene, which sets it apart. Polyethylene has an advantage over polypropylene in that it is more stable. Polypropylene has the benefit of being able to withstand repetitive movements, such as those required by a hinge. A polypropylene hinge can be opened and closed several times and still function properly.


Polyethylene is noted for its light weight, high durability, and low cost. Bottles, Poly bags, zip lock bags are all widely made using it. High density polyethylene (HDPE), low density polyethylene (LDPE), and polyethylene terephthalate are the most regularly used polyethylene polymers (PET).

  • Ultra-high-molecular-weight polyethylene (UHMWPE) is strong and chemically resistant. Moving machine components, bearings, gears, artificial joints, and some bulletproof vests are all made using it.
  • HDPE has a high tensile strength and strength-to-density ratio, can endure temperatures up to 120°C, and is solvent-resistant. It's also opaque, making it ideal for keeping goods that are light-sensitive. Milk jugs, detergent bottles, outdoor furniture, water drums are examples of HDPE goods.
  • Packaging film, sacks, and gas pipes and fittings are all made of medium-density polyethylene (MDPE).
  • Physically, LDPE Granules are more malleable. It has a lower tensile strength but better resilience, is non-reactive at room temperatures, and is resistant to most acids, alcohols, and bases. Low-density polyethylene (LDPE) is a flexible plastic that is used to make squeeze bottles, retail shop bags. 


Polypropylene, like polyethylene can be mixed with other materials. To make it more malleable, rubber might be added. Minerals are one of the most fascinating additions to polypropylene. The combination of minerals transforms a polypropylene sheet into synthetic paper. Plastic paper is what synthetic paper is. It's simple to print on. It may be folded, hot stamped, die cut, and sewed, among other things. The best quality is it is eco-friendly. Polypropylene is suddenly turned into a myriad of items. Banners, cards, maps, menus, signage, tags, booklets etc. 

Polyethylene is a relatively pliable polymer that stretches quickly, making it ideal for food packaging. Polypropylene is less flexible than polyethylene, but it is also more resistant to break. The plastic will have a greater or lower degree of elasticity depending on how it is oriented.


Polypropylene is a polymer that is significantly lighter than polyethylene. In terms of colour, the polypropylene is a translucent white in its natural state, whereas polyethylene is colourless. Different industrial extrusion methods are utilised to provide the best packaging attributes, such as improved transparency and pierceability. Because both polypropylene and polyethylene are thermoplastics, they are easy to recycle. This implies they may be formed repeatedly and melt when subjected to heat operations. These two polymers, in particular, can be given a new life after recycling. Polyethylene, on the other hand, is the more extensively recycled of the two.


Resource Box: There are many traders of Polypropylene and Polyethylene. One of the most renowned trader in premium quality ldpe granules is AVH Polychem Pvt. Ltd. It sells PE (Polyethylene), PP (Polypropylene), EVA (Ethylene Vinyl Acetate). They are well-equipped to respond to the specific needs of various sectors. AVH has always been known for its on-time delivery from the moment the customer places an order, as well as its state-of-the-art warehouse facility, which is so well-planned and organised that even a large quantity of product can be moved from storage racks to a transport vehicle in one go without requiring much human intervention. They have a specialised dispatch crew and forklift gear to safely and efficiently complete daily order dispatch.

Conclusion: The article clearly explains the difference between Polypropylene and Polyethylene. So make the right choice between the two based on your requirements.
