Analysis of what kind of carton can package food

With the rise of e-commerce, the use of cartons is increasing. Most of the products are packed in cartons, including fruits, fast food and other foods. The following specific analysis of what kind of carton can package food.

1、 Barrier performance

Paper and paperboard are porous fiber materials, which have a certain degree of permeability to moisture, gas, light, grease and so on, and their barrier properties are greatly affected by temperature and humidity, so they can meet the barrier performance requirements through appropriate surface processing.

2、 Processability

Paper and paperboard have good processing performance, can be folded, and can use a variety of sealing methods, easy to process into packaging containers with various performance, easy to realize mechanized processing operation. In addition, through proper surface treatment, the paper and paperboard can be provided with the necessary moisture-proof, insect proof, barrier, heat sealing, strength and physical properties, so as to expand its application scope.

3、 Mechanical properties

Paper and paperboard have certain strength, stiffness and mechanical adaptability. Its strength mainly depends on the paper material, quality, thickness, processing technology, surface condition and certain temperature and humidity conditions; In addition, the paper also has certain folding, elasticity and tearing properties, which is suitable for making shaped packaging containers or wrapping.

4、 Health and safety performance

In the process of paper processing, especially chemical pulping, there are usually some chemical substances left, so we must choose all kinds of paper and paperboard correctly and reasonably according to the contents of the package.

5、 Printing performance

Paper and paperboard have strong ability to absorb and bond ink and good printing performance, so they are often used as printing surface in packaging. The printing performance of paper and paperboard mainly depends on the surface smoothness, sizing, elasticity and adhesion.
