The materials of biscuit boxes are mainly divided into three types: paper, iron and plastic. The specific choice depends on the packaging type and functional requirements:
Main material types
Paper material
Gray-bottomed white board paper (grey copper paper): commonly used for boxes that need to be mounted with corrugated paper. The thickness is generally 250g-300g and has good printing adaptability.
White cardboard: suitable for non-corrugated paper boxes, also using 250g-300g specifications, smooth surface suitable for printing biscuit patterns.
Corrugated paper (E corrugated): used in combination with gray copper paper to enhance the compression resistance of packaging, but it should be noted that the paper wire direction is opposite to the corrugated direction to avoid deformation.
Iron material
Tinplate: mostly used for high-end biscuit gift boxes, with high strength, light-shielding, sealing, and high plasticity, and can make personalized box shapes such as star and round. Bright patterns can be printed on the surface, and it has anti-rust function.
Plastic material
PET/PP blister box: used for inner tray or independent packaging, PET is impermeable and acid and alkali resistant, PP is high temperature resistant (120℃) and can be heated in microwave, commonly used in food packaging such as moon cake trays and cake boxes.
