In the application of external valve port packaging, the choice of paper material has a significant impact on the compatibility and stability of the valve port.
First of all, common paper materials such as kraft paper, white board paper and corrugated paper have different physical properties. Kraft paper usually has high strength and toughness, but its surface roughness may have a certain impact on the sealing effect of the valve port. If the valve port and kraft paper are not closely fitted, it may increase the risk of leakage, thereby affecting the overall stability of the package.
The surface of white board paper is relatively smooth, which can provide a better fit of the valve port and help improve the sealing performance. However, its strength may be relatively weak, and it may be prone to deformation or damage when subjected to the pressure and operation of the valve port for a long time, affecting the stability of the valve port.
Due to its unique multi-layer structure, corrugated paper has good cushioning performance and pressure resistance. However, the poor surface flatness of corrugated paper may bring challenges to the installation and sealing of the valve port. When using corrugated paper as the packaging material for the External valve port, special attention should be paid to the connection and sealing between the valve port and the corrugated layer to ensure the stability of the package.
In addition, the water absorption of paper is also an important factor. Some paper materials are easy to absorb moisture, which may cause the paper strength to decrease and the joint between the valve port and the paper to loosen in a humid environment, thereby affecting the stability of the valve port and the sealing performance of the package.
Paper of different materials also has different tolerance to chemicals. If the items in the package are corrosive or volatile, the paper material may be corroded or deteriorated, which will affect the compatibility and long-term stability of the valve port.
In addition, the processing technology and surface treatment of the paper will also affect the compatibility and stability of the valve port. Paper that has been coated or laminated may improve its surface properties and sealing effect, but it may also increase costs.
In summary, when selecting paper of different materials for external valve port packaging, it is necessary to comprehensively consider factors such as paper strength, surface properties, water absorption, chemical resistance, and processing technology to ensure good compatibility between the valve port and paper and long-term stability of the packaging, and meet the packaging needs and quality requirements of the product.
