One-stop solution for PET sheet thermoforming fruit and vegetable packaging boxes

The market demand for PET fruit and vegetable packaging boxes is strong, and investing in transparent PET sheet thermoforming projects has broad market prospects. To successfully operate this project, high-quality thermoforming machines, customized molds and highly transparent food-grade PET sheets are required. In addition, the final market of the product covers supermarkets, fresh food distribution, catering, cold chain logistics and other industries to ensure long-term profitability.

A chain supermarket needs to customize a highly transparent and impact-resistant fruit packaging box, with the following requirements:

• Meet food-grade safety standards and can directly contact fruits;
• Support refrigerated transportation (no brittle cracking at -20℃);
• The box body has air holes to extend the shelf life of blueberries;
• The monthly demand is 500,000 pieces, and the cost is controllable;
