I. Replacing blister packaging and polystyrene foam with paper trays can effectively reduce environmental pollution. Traditional plastic packaging materials are difficult to degrade, persist in the natural environment for a long time, and cause severe pollution and damage to soil and water sources. In contrast, paper-based packaging materials can degrade naturally in a short period without causing long-term pollution or damage to the environment. Therefore, replacing blister packaging and polystyrene foam with paper trays can effectively reduce environmental pollution and protect the health and stability of the ecological environment.

II. Replacing blister packaging and polystyrene foam with paper trays can improve the sustainability of packaging materials. Traditional plastic packaging is for single use and hard to recycle or reuse after use. However, paper-based packaging materials can be recycled and reused, which enhances the sustainability of packaging materials. Thus, replacing blister packaging and polystyrene foam with paper trays can promote the sustainable development of packaging materials and realize the effective utilization and conservation of resources.

III. Replacing blister packaging and polystyrene foam with paper trays can increase the added value and quality of products. Paper-based packaging materials have a good texture and touch, which can enhance the added value and quality of products. At the same time, through printing and design, paper-based packaging materials can achieve personalized and differentiated packaging effects, improving the product’s market competitiveness and brand image.

IV. Replacing blister packaging and polystyrene foam with paper trays can promote the transformation and upgrading of the packaging industry. Traditional plastic packaging materials are facing the dual challenges of environmental pressure and market competition, making transformation and upgrading necessary. As a new type of packaging method, replacing blister packaging and polystyrene foam with paper trays can drive the transformation and upgrading of the packaging industry and push it toward an eco-friendly and sustainable direction.

In conclusion, as a new packaging method, replacing blister packaging and polystyrene foam with paper trays has obvious advantages. It can effectively reduce environmental pollution and contribute to environmental protection and sustainable development.
