Blister trays are a type of packaging commonly used to protect and display products. They are designed to hold individual items securely and provide visibility while protecting them from damage, tampering, or contamination. Blister trays can be classified based on different criteria, including:
- Material:
- Plastic Blister Trays: These trays are made from various types of plastic, such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PP (polypropylene). Plastic blister trays offer good clarity, durability, and flexibility.
- Foam Blister Trays: These trays are made from foam materials like polyurethane foam or expanded polystyrene (EPS). Foam trays provide cushioning and protection for delicate or fragile products.
- Design:
- Standard Blister Trays: These trays have a basic design with cavities or pockets that hold individual products. The cavities can be customized to fit the specific shape and size of the items.
- Clamshell Blister Trays: These trays consist of two hinged halves that enclose the product. They are often used for products that need to be securely sealed and protected.
- Functionality:
- Display Blister Trays: These trays are designed to showcase the product and allow clear visibility, typically featuring a transparent plastic lid or front cover.
- Protective Blister Trays: These trays prioritize product protection and security, providing a barrier against external factors such as moisture, dust, or tampering.
- Application:
- Food Blister Trays: These trays are specifically designed for packaging food items, ensuring hygiene, freshness, and presentation.
- Medical Blister Trays: These trays are commonly used in the healthcare industry to package medical devices, pharmaceutical products, or surgical instruments.
It’s important to note that these classifications are not mutually exclusive, and blister trays can fall into multiple categories based on their material, design, functionality, and application. Manufacturers often tailor blister trays to meet the specific requirements of the product and industry they serve.
