  2. Cold Formed Blister Packs: This method involves layering aluminum foil with plastic film to create a durable, protective barrier. Cold formed packs are ideal for products that require high barrier protection, such as medications that are sensitive to moisture and light.
  3. Clamshell Blisters: Clamshells are hinged blister packs that can be opened and closed like a clamshell. They are often used for electronics, toys, and hardware items because they provide extra security and product visibility.
  4. Blister Cards: In this variation, the blister pack is attached to a cardboard backing. This type is frequently seen in retail settings, as the backing can be printed with product information and branding.

Applications of Blister Foil Packaging

Blister foil packaging is versatile and used across many industries:

  1. Pharmaceuticals: It’s perhaps most well-known in the pharmaceutical industry, where it protects tablets, capsules, and other medications from environmental factors and tampering.
  2. Consumer Goods: Items like batteries, small electronics, and toys often come in blister packs to prevent damage and theft while allowing consumers to view the product before purchase.
  3. Food and Beverage: Blister packs are used for packaging items like gum, candy, and single-serving food products, providing a barrier to maintain freshness and prevent contamination.
  4. Industrial Goods: Small hardware items such as screws, bolts, and other fasteners are often packaged in blister packs for ease of use and visibility.

Creating blister foil packaging involves several key steps:

  1. Design: The process begins with designing the mold or form that will shape the plastic. This design considers the size and shape of the product as well as any branding or informational needs.
  2. Forming: Depending on the type (thermoforming or cold forming), the plastic or aluminum foil is shaped to encase the product securely.
  3. Filling: The formed blisters are then filled with the product. In the case of pharmaceuticals, this step often involves automated machinery to ensure precision and hygiene.
  4. Sealing: After filling, the blister is sealed with a backing material, such as aluminum foil, paper, or plastic. This seal is crucial for protecting the product from external elements.
  5. Cutting and Finishing: Finally, the blister packs are cut to size and may undergo additional finishing processes, such as adding perforations for easy opening or printing branding and information.
