Important factors affecting the stiffening Of Cigarette Boxes Of Hotstamping paper and paperboard

The importance of paper and paperboard stiffening

Flatness is a basic performance index for Cigarette Boxes Of Hotstamping paper and whiteboard paper.

Paper stiffness is a very important indicator, which directly affects the size of crease stiffness (another factor is die cutting pressure), thus affecting the molding of the finished product. The stiffness is small, the finished product is easy to crush, warping; Large stiffness, the finished product is difficult to form.

Packaging paper has requirements on stiffness, different quantitative paper stiffness is different, generally proportional to the square Of the thickness, the thicker the paperboard, the higher the stiffness.

Factors affecting flexural stiffness

There are many factors that affect the stiffness. The thickness and elastic modulus Of paperboard are the most basic factors affecting the stiffening of paperboard or paper. When the thickness is constant, the stiffening increases with the increase of the tightness. When the weight was constant, the stiffness increased slightly and then decreased slightly with the increase of the tightness, but the overall trend was a net increase.

Cigarette Boxes Of Hotstamping is a test method for the stiffness of paper and paperboard

The stiffening measurement methods include fixed and non-fixed Angle test sample flexural strength, sample free bending to measure its strength change. Some test methods have both. The Clark and Greyer method is commonly used to measure the stiffness of paper.
