Understanding Clamshell Blister Packaging

What is Clamshell Packaging?

Clamshell packaging uses two plastic pieces. These pieces form a protective shell around products. They create a secure, visible enclosure for items.

The packaging consists of two main components. Plastic blisters form the protective shell. Sealing mechanisms keep everything securely closed. This design provides excellent product visibility.

Clamshell packaging differs from other blister types. It offers complete product enclosure. Traditional blister packs have backing cards only. Clamshell provides all-around protection.

Common Applications of Clamshell Packaging

  • Lipstick and makeup packaging

  • Sunscreen and cream containers

  • Sample product displays

Electronic Components

  • Small device packaging

  • Battery and accessory holders

  • Circuit board protection

Hardware and Tools

  • Drill bit organizers

  • Small tool packaging

  • DIY project components

Consumer Retail Products

  • Toy packaging

  • Office supplies

  • Small household items

Professional Sealing Methods for Clamshell Packaging

Button Seal Technology

Button seals use concave and convex parts. These interlocking components snap together securely. They create a strong mechanical bond.

This method works well for lightweight products. Cosmetics and small electronics benefit greatly. The seal provides reliable security.

Button seals offer easy opening and closing. They maintain package integrity through multiple uses. Customers appreciate the convenience.

Hinge Seal Systems

Hinge seals create rail-like closure systems. They allow packages to open like books. This design provides excellent access.

Choose hinge seals for frequently used items. Tools and reusable products work perfectly. The design supports multiple openings.

These seals offer exceptional durability. They withstand repeated use without failing. The mechanism remains reliable.

Heat Seal Techniques

RF (Radio Frequency) Sealing

RF sealing uses radio waves for bonding. It creates molecular-level connections between materials. The result is extremely strong seals.

This method works with various plastics. PVC and PET materials seal beautifully. The process ensures consistent quality.

RF sealing delivers high production speeds. It maintains excellent seal quality throughout runs. Manufacturers achieve great efficiency.

Ultrasonic Sealing

Ultrasonic sealing uses high-frequency vibrations. These create heat through material friction. The process bonds materials seamlessly.

It works particularly well with hard plastics. ABS and polycarbonate respond excellently. The seals remain very strong.

Quality control is straightforward with ultrasonics. Operators can monitor the process easily. Consistency is reliably maintained.

Equipment Solutions for Different Production Needs
