Hot Sale Eco Friendly Paper Tube Packaging It is more common in the current market, because it is not only easy to be damaged as a package, but also safer and convenient to carry. Then we will introduce the physical performance indicators of the paper tube packaging.
1. Quantitative: The weight is expressed in g/m2. For example, the amount of paper for cultural printing is generally 32-80 g/m2, and the basis weight of paperboard is generally 200-400 g/m2.
2. Thickness: The thickness directly measured under the pressure of 100 kPa between two measuring plates, expressed in mm.
3. Tightness: It indicates the degree of tightness of the industrial paper tube structure in Dongguan. The weight of paper per cubic centimeter is expressed in g/cm3. For the same amount of paper, the paper with a large thickness is loose.
4. Expansion ratio: The relative change of the paper size after the paper is immersed in water or humidified or dehumidified at different temperatures, expressed as the percentage increase or decrease of the size of the original sample. Offset paper requires a higher rate of expansion.
5. Porosity and air permeability: Generally, paper contains 70% of pores. The air permeability is expressed in ml/min or s/100ml, respectively, in a certain area of paper under a certain degree of vacuum, the amount of air per minute or the amount of air passing through a certain amount of air.
6. Strength: The paper is subjected to external force and reaches some specific values reflected by the damage point. It mainly has tensile strength and elongation at break, bursting resistance, folding resistance, tearing degree, rigidity and the like. The strength indicators are especially important for wrapping paper.
