Polyolefin Plastic SheetsPolyolefins are a family of durable, versatile plastics made from natural gases. Inexpensive and easy to manipulate, plastic sheets made of polyolefins are often the preferred material for use in consumer goods, structural plastics, food packaging and industrial products. These multi-talented resins perform well over a range of temperatures and in a variety of electrical applications. They are chemically resistant, odorless and nonporous, and can be easily scored to produce three-dimensional packaging products.
