Clamshell Blister Packaging: What are the key factors in material selection?

Material selection for Clamshell Blister Packaging involves several key factors that together determine the performance, cost, environmental friendliness and applicable scenarios of the packaging. The following is a clear summary and explanation of these key factors:

1. Material performance

Mechanical properties: including the tensile strength, impact strength, bending strength, etc. of the material, which determine whether the packaging can effectively protect the product from damage during transportation and use.

Temperature resistance: Consider the stability of the material in high or low temperature environments to ensure that the packaging can maintain its shape and function under different climatic conditions.

Corrosion resistance: For products that may come into contact with corrosive substances such as water and chemicals, packaging materials need to have good corrosion resistance.

Transparency: For packaging that needs to show the appearance of the internal product, transparency is an important factor. Materials such as PET and PVC are often selected for their good transparency.

2. Cost-effectiveness

Material cost: The cost of different materials varies greatly, and it is necessary to select cost-effective materials based on product value, market demand and budget.

Processing cost: Including process costs such as molding, cutting, and printing. Some materials may be easier to process, thus reducing overall costs.
Recycling and reuse: Consider the recyclability and reuse value of materials, which can help reduce long-term costs and meet environmental requirements.
3. Environmental protection
Degradability: With the increase in environmental awareness, more and more companies are beginning to pay attention to the degradability of packaging materials. Bio-based materials or degradable plastics are important choices for environmentally friendly packaging.
Toxicity: Ensure that packaging materials do not release toxic substances during use to protect consumer health and environmental safety.
Resource consumption: Selecting materials with low resource consumption and environmentally friendly production processes can help reduce the impact on the environment.
4. Applicability
Product characteristics: Select appropriate packaging materials based on the shape, size, weight and other characteristics of the product. For example, for fragile products, you need to choose materials with higher strength; for heavy products, you need to consider the material's load-bearing capacity.
Market demand: Understand the target market's preference and acceptance of packaging materials in order to select materials that meet market demand.
Laws and regulations: Comply with the laws and regulations of relevant countries and regions on packaging materials to ensure that the product can enter the market smoothly.
Specific material examples
PET (polyethylene terephthalate): has good transparency and mechanical properties, and is widely used in blister packaging in food, medicine, cosmetics and other industries.
PVC (polyvinyl chloride): low cost, good processing performance, but relatively poor environmental protection, and some countries and regions have restricted its use.
PP (polypropylene): has high temperature resistance and corrosion resistance, suitable for product packaging that requires high temperature or chemical stability.
Bio-based materials: such as PLA (polylactic acid), etc., are derived from renewable resources, have good biodegradability, and are an important choice for environmentally friendly packaging.
In summary, the material selection of Clamshell Blister Packaging needs to comprehensively consider multiple factors such as material performance, cost-effectiveness, environmental protection and applicability. In practical applications, it should be weighed and selected according to specific needs and conditions.
