Analysis of what can be food packaging carton
With the development of e-commerce, the carton was used more and more, the majority of products using cartons, including fruit, fast food and other food. Here a specific analysis of what can be food packaging carton.
A, barrier properties
Paper and paperboard belongs to the porous fiber material, permeability has a certain degree of water, gas, light oil, etc., and the barrier is influenced by temperature and humidity is bigger, can pass the appropriate surface processing to meet the requirements of its barrier properties.
Two, processing performance
Paper and board has good processing properties, folding processing, and can use a variety of sealing mode, easy processing into a packaging container with a variety of performance, easy to realize mechanization processing operation. In addition, by processing the surface properly, can provide the necessary moisture resistance, insect resistance, barrier property, thermal sealing, strength and physical performance for the paper and paperboard, expand the scope of its application.
Three, mechanical properties
Paper and paperboard has a certain strength, stiffness and mechanical adaptability, it mainly depends on the strength of the size of paper materials, quality, thickness, processing technology, surface condition and a certain temperature and humidity conditions; in addition the paper has certain elasticity and folding, tearing, suitable for making molded packaging container or for wrap.
Four, health and safety performance
In the process of the paper, especially the chemical pulping, usually chemical residues must, therefore must be based on the contents of the package to the selection of all kinds of paper and paperboard.
Five, printing performance
Paper and paperboard ink absorption and bonding ability, good printing performance, so in the packaging used for printing surface. Printing properties of paper and paperboard depends mainly on the surface smoothness, rubber, elastic and adhesive force etc..
