Paper and cardboard have good processing performance, can be folded and sealed using various methods, and are easy to process into packaging containers with various properties. They are also easy to achieve mechanized processing operations, and there are mature production processes available recently. Good processing performance creates conditions for designing various functional structures such as windows, handles, partitions, and design display tables. In addition, through appropriate surface processing, paper and cardboard can be provided with comparative moisture resistance, insect resistance, barrier properties, heat sealing properties, strength, and physical properties, expanding their range of use.

Carton and cardboard have certain strength, hardness, toughness, and compression resistance, and their strength mainly depends on the material, quality, thickness, processing technology, surface condition, and certain temperature and humidity conditions of the paper; In addition, paper also has certain folding, elasticity, and tearing properties, making it suitable for making molded packaging containers or for wrapping.
