1. Food safety: Ensure the freshness and hygiene of ingredients and avoid using ingredients that have expired. Ingredients such as meat should be cooked or grilled to ensure food safety.
2. Packaging options: Use packaging materials that are suitable for food, such as food-grade cartons, plastic wrap, food bags, etc., to prevent ingredients from coming into direct contact with the box or other packaging materials.
3. Avoid squeezing: Avoid packing the burgers too tightly so that the ingredients are not flattened or the packaging is damaged.
4. Label the package: Label the package with the type of ingredient and the date of preparation so that it can be traced and identified when needed.
5, maintain the temperature: if you need to maintain the temperature of the burger, you can add insulation bags or insulation materials in the package.
