Thin gauge thermoforming is also known as “in-line” thermoforming. This thermoforming application utilizes styrene, PETG, and clear PVC plastics. The plastic sheets range from .010” to .055” thick. These thin plastics are most commonly used in mass produced packaging materials. Products manufactured using thin gauge plastics are generally used in packaging food, medical, and small consumer items. Food and medical packaging is typically manufactured in ISO certified clean rooms to ensure sanitation. Common types are shell packaging that completely encases an item and is heat crimped to seal it. This works as an anti-theft protector along with protecting items from the outside environment. Thinner more bag like packages are heat crimped on both ends, but are easier to tear open because of how thin the plastic casing is.
