How Do Blister and Shrink Sealing Work?

Blister sealing involves securing a product between a pre-formed plastic blister and a backing material. The product is placed inside the cavity, and the backing material is then heat-sealed to the blister using specialized equipment. This creates a tight seal around the item and protects it from environmental factors such as moisture, light, and dust.

Shrink sealing is wrapping a product with a plastic film before exposing it to heat. This causes the film to shrink and tightly conform to the product’s shape, creating a protective barrier. It can be carried out manually or automatically. A shrink seal is used in retail to package products across all CPG industries.

Benefits of Heat Sealing Techniques in Packaging

Heat sealing techniques such as blister and shrink sealing offer various benefits, making them popular in the packaging industry. Here are some of the major advantages they provide:

Guaranteed Protective Barrier

Blister and shrink sealing use heat to create a seal between a plastic blister or wrap and the product inside. This seal forms a protective barrier around the product, preventing moisture, dust, and other contaminants from entering. The techniques also help to keep the product stable, minimizing the risk of physical damage during transport and handling.

Customization Capabilities

A blister or shrink seal can be used with various materials, colored or printed with custom designs or logos. This gives businesses the flexibility to create packaging that reflects their brand, helping attract customers and build brand recognition. It can also be customized to fit various product shapes and sizes, ensuring the packaging fits snugly around the item.

Cost-Effectiveness

Most heat sealing techniques require minimal setup time and can be performed quickly, reducing labor and production costs. They also use fewer materials than other packaging methods — such as clamshells or boxes — reducing material costs and minimizing waste. Particularly, blister and shrink sealing offer high-speed production capabilities, with the ability to produce thousands of units per day at a low price.
