What materials are Clamshell Blister Packaging usually made of? What properties do these materials have?

Clamshell Blister Packaging is made from a variety of materials, but the most common include plastic and cardboard. Below, I'll explain these materials and their properties in detail:
Plastic material:
Polyvinyl Chloride (PVC): PVC is widely used due to its good transparency, flexibility and durability. It provides excellent moisture and dust resistance while also protecting the products inside from physical damage.
Polyethylene (PE) and polypropylene (PP): These plastic materials also have excellent moisture- and dust-proof properties. They are generally more malleable than PVC and are suitable for packaging requiring greater durability.
Polyester (PET): PET is a highly transparent plastic that is not only beautiful but also has excellent heat and chemical resistance.
Thermoplastics: These materials can be shaped when heated and retain their shape when cooled, making them ideal for making blister packs.
Characteristics of plastic materials typically include:
High transparency: Allow consumers to clearly see the product inside the package.
Moisture-proof and dust-proof: effectively protect the product from damage by external environmental factors.
Durability: Resists physical impact and abrasion, protecting product integrity during transportation and storage.
Recyclability: Many plastic packaging materials can be recycled and reused, helping the environment.
Cardboard material:
Coated cardboard: The surface of coated cardboard has been specially treated and has good printing performance and strength.
Composite cardboard: This type of cardboard is composed of multiple layers of material, often including plastic film and paper layers, to provide strength and moisture resistance.
Characteristics of cardboard materials typically include:
Printability: Smooth surface, suitable for high-quality printing, increasing the visual appeal of packaging.
Cost-Effectiveness: Relative to plastic, paperboard is generally cheaper and suitable for mass production.
Environmentally Friendly: The cardboard is recyclable and biodegradable, making it environmentally friendly.
Some strength and durability: Although not as good as some plastic materials, cardboard can provide adequate protection through structural design and coating treatments.
When selecting materials for Clamshell Blister Packaging, you usually need to consider factors such as the nature of the product, packaging requirements, cost budget, and environmental protection requirements. Different materials can meet different needs, so choosing the most suitable material is crucial to ensuring packaging effectiveness and meeting market demand.
