Food packaging cartons are made from a variety of materials, such as white paperboard, kraft paper, and corrugated cardboard. Each material has distinct characteristics: white paperboard offers high rigidity and excellent print quality, making it ideal for premium food packaging; kraft paper is popular in the organic and health food sectors due to its natural texture and eco-friendly qualities; and corrugated cardboard is frequently used for foods requiring shock-resistant transport thanks to its superior cushioning properties.
Plastics: PP (No. 5, microwave-safe), PET (No. 1, beverage bottles), PS (No. 6, foam food containers), PE/LDPE, etc.; among these, PP is best suited for heatable food containers.
Paper-based: Kraft paper, composite paperboard, paper-plastic composites, etc.; commonly used for milk cartons, fast-food containers, and pastry boxes.
Metals: Tinplate, aluminum cans; offer excellent sealing properties and are widely used for canned goods and beverages.
Glass: Chemically stable; used for jams, canned foods, and beverage bottles.
Composite materials: Aluminum-plastic composite films, paper-plastic composites, etc.; offer superior barrier properties.
