Understanding Blister Packaging and Flange Security

Blister packaging is a widely used form of packaging that typically consists of a pre-formed plastic shell known as a blister and a backing that can be made of paper, cardboard, or plastic. The primary purpose of blister packaging is to protect the product inside while providing visibility to the consumer.

What Are Flanges in Blister Packaging?

Flanges refer to the thin edges of the blister that extend outside the molded cavity. These edges play a crucial role in securing the blister to its backing material. Effective sealing along the flanges is essential to ensure the integrity of the packaging.

Why Use Tape Along the Flanges?

Using tape along every flange in blister packaging offers several advantages:

• Enhanced Security: Tape adds an additional layer of adherence, preventing the blister from detaching from the backing during transportation or storage.
• Protection Against Tampering: A properly taped flange makes it more difficult for someone to tamper with the blister packaging without noticeable signs.
• Moisture and Contamination Barrier: Taped flanges help to shield the product from moisture and contaminants that might otherwise enter through the edges.

Application of Tape on Flanges

To effectively secure a blister package using tape:

1. Select the Right Tape: Choose a tape that is strong and designed for packaging purposes, ideally with weather-resistant qualities.
2. Prepare the Blister and Backing: Ensure the surfaces are clean and free from dust or other contaminants.
3. Apply Tape Consistently: Lay tape along each flange. It’s important to apply even pressure to ensure a strong bond.
4. Inspect the Seals: After taping, check for any uneven areas or gaps that may need additional tape or re-sealing.

Conclusion

Utilizing tape along every flange to secure blister packaging is a valuable step in the packaging process. It not only reinforces the product's safety and integrity but also contributes to consumer confidence in product quality. Understanding these basic principles of blister packaging will help you appreciate the intricacies involved in securing products effectively.
