Film extrusion
At Shell Polymers, we understand that a converter’s business runs entirely on resin—which is why we’re committed to helping converters find the right resin that fits your needs. That’s why our polymers undergo rigorous testing for tensile strength, impact resistance, tear strength and more. Each formulation is built to deliver consistent performance in polyethylene film applications. The end result? A quality and reliable supply that meets the demands of modern polyethylene film production.

Product 101
At Shell Polymers, our polyethylene resins help protect quality and optimize production across various types of packaging and types of food packaging materials. Explore the technical details below to compare melt index, density and documentation for each of our food-grade options.
Density is reflected by the first two numbers found in the product name, which is 18 in this instance. These numbers represent the last two significant digits of the density value. See examples below.
18 = 0.918 density
53 = 0.953 density
63 = 0.963 density
