Abstract: This paper measured the vibration transmissibility of several honeycomb paperboards and the attenuation coefficient. Laboratory was used to determine the natural frequency of the thickness of 10mm, 20mm, 30mm, 40mm Honeycomb Paperboard. The test results show that the honeycomb paperboard resonance frequency decreases with increasing thickness, while the vibration transmissibility increases with increasing thickness. We have also established finite element model of honeycomb paperboard to simulate its vibration properties. The result of simulation is in good coincidence with the experimental result. In addition, some cases can use computer simulation instead of laboratory testing to obtain the natural frequencies of honeycomb paperboard.

Abstract: Studied the vibration performance of honeycomb paperboard with double cross-core, obtained vibration transmissibility curve of honeycomb paperboard with double cross-core, by the curve indicated, the vibration transmission properties of the honeycomb paperboard with double cross-core in the sinusoidal excitation ,and the packaging materials as contents when the size of the protection capacity. The results show that the shock resistance capacity of honeycomb paperboard with double cross-core is supers the single layer with the same thickness of.

Abstract: The overall effect of sealing the packaging has a very important role. Sealed plastic containers divided into four main ways, namely the bundle sealing, adhesive sealing, physical sealing and filling and sealing. They have their own characteristics. Bundling seal means the product can not be sealed, but its use is very wide, has a high degree of freedom. Low adhesive strength of adhesive sealing, but it is widely used. More complex structure of the physical sealing, but it has a wide variety of functions. Used in the filling and sealing gaskets are susceptible to damage, but it has a good seal. This paper analyzes the principles of their seal,which allows you to choose different sealing materials and the corresponding sealing structure to meet a variety of packaging needs.
