Food, beverage and consumer products industries rely on PET for many of their packaging needs. Among the common applications are:

PET’s popularity among PET injection molding manufacturers and their customers is a result of the availability of the materials and relatively low cost. In addition, PET is:

PET was first polymerized for use as textile fibers known as polyester. Today, PET injection molding manufacturers utilize the material to produce strong, lightweight packing.

Although it looks and feels like PET, PETG (or copolyesters) is a modified PET, produced by adding a second glycol during polymerization. PETG removes the hazing that can impact PET and reduces the crystalline effect that can cause PET to become brittle. PET plastic injection molding machines can use PETG to produce bottles that are softer and more pliable for a more comfortable grip. PETG offers clarity, toughness and stiffness and is used in medical test tubes and bottles, lighting fixtures and appliances. The material’s benefits come with a higher cost than the cost of PET.

Consumers commonly find PET as the material used in plastic jars, convenience packaging and plastic bottles, including those used for carbonated beverages. In the 60 years since it was first introduced, PET has become one of the most widely used and most sustainable plastic materials in the world. Interested in using this material for your project?
