What Kind of Different Types of Glass Used in Packaging?

Glass is a premier packaging material, but not all glass is created equal. This article breaks down the three main classifications of glass used for containers (Type I, II, and III). We focus on Soda-Lime Glass (Type III), the most widely used and cost-effective option for products ranging from Mason jars to beverages. We explore its chemical composition—silica, soda ash, and lime—and detail the key reasons for its dominance in the consumer packaging industry: chemical inertness, versatility, and 100% recyclability.
