Case Background
With the rapid development of the dairy market, cheese are widely loved by consumers as a convenient and healthy snack. In terms of packaging, customers hope to use lightweight and cost-effective materials to make packaging shells, which can not only protect the freshness of the product, but also present a high-quality appearance, while meeting food safety and environmental protection requirements. The customer finally chose to purchase 0.24mm thick PS (polystyrene) plastic sheets from our company for thermoforming processing to make cheese packaging shells.
Characteristics of PS plastic sheets
PS plastic sheets are a thermoplastic material widely used in food packaging, with the following significant characteristics:
Easy to process: It has good ductility and molding effect during the thermoforming process, and is suitable for packaging of various complex shapes.
Lightweight and durable: Keep the packaging light while providing sufficient strength to protect the cheese.
Food safety: The material meets food grade standards and has no odor, ensuring the safety of the product.
Economical: The cost is relatively low, suitable for large-scale production, and cost-effective.
Customer needs and challenges
Customers’ specific needs for cheese packaging shells include:
- Durability: The packaging shell must have a certain degree of pressure resistance to prevent damage during transportation and storage.
- Food safety: The packaging shell must pass food grade certification to ensure the safety of direct contact with cheese.
- Production efficiency: The sheet must adapt to the customer’s efficient thermoforming equipment to ensure rapid production.
- Environmental protection: Try to choose recyclable materials to reduce environmental impact.
Our solution
According to customer needs, our company recommended a 0.24mm thick high-transparency PS plastic sheet and provided the following support:
Material optimization: The sheet has high transparency and a smooth surface, perfectly presenting the shape and color of the cheese.
Processing adaptation: The sheet has been professionally debugged, has excellent ductility during the thermoforming process, and has a forming rate of more than 98%, effectively reducing material waste.
Food grade certification: Provide material certification that meets international food contact material standards to enhance customer trust.
Environmental commitment: Use recyclable PS materials and provide customers with suggestions for waste recycling and treatment to meet green production needs.
Project results and customer feedback
After several trial productions, the customer successfully completed the mass production of cheese packaging shells. The following are the main results:
- Excellent product performance: The cheese packaging shell is transparent and beautiful, attracting more consumers’ attention.
- Improved processing efficiency: The material performance is stable, and the production speed is increased by 15%, which reduces the production cost for customers.
- Positive market feedback: The quality and appearance of the packaging shell are deeply loved by consumers, and sales have increased significantly.
- Environmental benefits are evident: The application of recyclable materials has enabled customers to improve their green brand image.
The customer said that the PS plastic sheet provided by our company is not only of excellent quality, but also professional service, which has provided great help from material selection to subsequent technical support. This cooperation not only achieved the project goals, but also laid a solid foundation for the two parties to establish a long-term cooperative relationship.
