What is the Difference Between PP and PE Bags?
What is the Difference Between Pp and Pe Bags ? Polypropylene (PP) and Polyethylene (PE) are two commonly used plastic materials in the packaging industry. While both materials are widely used in the production of bags, there are significant differences between the two that affect their applications and properties. In this article, we will explore the differences between PP and PE bags. Composition and Manufacturing Polypropylene (PP) is a thermoplastic polymer that is derived from propylene. PP is a versatile material that is lightweight, durable, and has a high melting point. PP bags are manufactured using a process called extrusion, which involves melting the material and extruding it through a die. The extruded material is then cooled and cut to form individual bags. Polyethylene (PE) is a thermoplastic polymer that is derived from ethylene. PE is a widely used material due to its high flexibility, low density, and ease of processing. PE bags are manufactured using the ...
