(1) the food packing carton has the structure of the multiphase mixed and disorderly element composition.
In the paper the composition of both long and short fibers from different sources (
First is less plant fiber, synthetic fiber and mineral fiber)
, packing, rubber and ink.
The warp and woof of plant fiber is the most varieties of paper structure, because the kinds of fiber raw material and processing method is different, they have different structures and properties.
(2) structural elements distributed on each other in three straight direction anisotropic, performance in the fiber is put in a different direction, different scale fiber distribution, and rubber, pigment, filler, and the spread of air is also different.
The anisotropy of this kind of structure, the primary resolution in writing methods and use of equipment.
It is also the primary aspects of sheet properties have different effects.
The tendency of fiber flocculation on each direction also has effect on the properties of the paper.
(3) the structure of the capillary colloid feature resolution more certain properties of the paper, such as absorption, air permeability, hygroscopicity, moisture changes, the deformation of the because of boring the irreversible change in nature, and so on.
(4) the paper the structure of the elements has a resolution between the adhesion strength of the mechanical strength and other properties of the paper.
Food packing carton (5) most of the paper structure has duality, namely the double properties of sheet is different.
The resolution not only in the above has pointed out that the anisotropy of the structural elements of spread, and also double condition of different resolution in paper.
Paper double-sided condition is different, usually because one side of the paper and the touch screen, touch the other side, and a blanket, accordingly leave marks on paper surface.
Touch screen that is not too smooth, and the more porous.
Food packing carton structure elements of the component is mixed and disorderly and are multidirection, and spread is anisotropic.
Thus, even if the paper quantitative fixed (
Deviation is not more than + / - 2%)
, the nature of the paper size is very big also, the thickness of plus or minus 5%, breaking length plus or minus 20%.
