The meaning of polypropylene vs. polyethylene bags lies in the distinction between the two materials and their respective applications in bag production.

Polypropylene bags are made from polypropylene, a thermoplastic polymer known for its toughness, strength, and resistance to heat and chemicals.

Ultimately, the choice among the two types of bags depends on the intended use and the desired properties for the specific application. The following guide will help you understand the actual difference between polyethylene and polypropylene bags.

Chemical Structure & Properties of Polypropylene VS Polyethylene Bags:

Polypropylene is a semi-crystalline thermoplastic polymer with a linear structure. PP bag is resistant to fatigue and can withstand higher temperatures compared to polyethylene. It is commonly used in applications requiring durability and resistance to moisture, chemicals, and fatigue. If interested in buying a PP woven bag, BOPP bag or PP bag - Lincoln Polymers has you wrapped.

Polyethylene is a versatile thermoplastic polymer with a simple linear structure. It is characterized by its flexibility, low density, and excellent impact resistance. PE is available in various forms, including high-density polyethylene (HDPE) and low-density polyethylene (LDPE), each offering unique properties and applications.

Difference Between Polyethylene and Polypropylene Bags

The table below will help you understand the main differences between PE and PP, allowing you to make an informed decision when selecting a packaging bag for your business. So, keep an eagle eye out!

Aspects Polyethylene Packaging Bag Polypropylene Packaging Bag
History Invented in 1898 by German chemist Hans von Pechmann, but commercial production began in the 1930s with low-density polyethylene Invented in 1954 by Italian chemist Giulio Natta, with commercial production starting shortly afterward
Structure A bag made up of ethylene monomers A Bag made up of propylene monomers
Melting Point Lower melting point High melting point
Market Size Polyethylene is one of the most widely produced plastics globally, with a market size of over 100 million metric tons annually. Polypropylene is the second most widely produced plastic after polyethylene, with a global market size of over 70 million metric tons annually.
Types LDPE, LLDPE , HDPE and HMDPE. Standard PP bags, BOPP laminated bags, block bottom bags, gusseted bags, and more.
Strength Good tensile strength and flexibility. High strength and tear resistance.
Applications Grocery stores, food packaging, shopping bags, retail bags, trash bags, etc. Packaging grains, seeds, and fertilizers, as well as in construction for sandbags and industrial packaging.
Environmental Contribution to plastic pollution and environmental degradation, leading to increased efforts for recycling. Compared to polyethylene bags, polypropylene bags are easy to recycle, reusable, and follow a sustainable approach.
