Packaging structure plays a leading role in packaging engineering and it is also the basics of packaging design. We should conduct the research of packaging structure under the system of “People-Packaging-Product-Environment”, as well as adhering to the design principles of human-orientation and environmental friendliness.

Package Structure Design:

Optimum Structure Design:

According to the design requirements, we can set up mathematics model, mechanics model and the objective function (the highest intensity, the lightest weight, the minimum cost, etc.) in all feasible structural schemes for the design problems of packaging structure. Also, the design variables and the constraint conditions of geometry, strength, rigidity and stability which the design should adhere to should be taken into account. Then mathematical methods and computer technology should be adopted to calculate and analyze a number of design schemes, from which to choose a best scheme to meet the design criteria.

Structure Strengthening Method:

Take measures to strengthen, replace or adjust the internal forces of those package structures and related parts whose reliability is inadequate or need to be improved.

Research points:

The optimized design of sharing pallets based on CAD/CAE.

The design of honeycomb cardboard pallets.

The theory and design of corrugated box forming.

The theory and method of structural strengthening of outer packing box.

The application of finite element method in optimal design of package structure

Cushioning Package:

The design of cushion packaging is influenced by many random factors, such as the circulation environment condition, the material properties, the geometric parameters of the buffer, and the brittle value of the product. It is difficult to precisely characterize the suitable degree of the product's cushioning package. The reliability theory and method can reflect more objectively and precisely the influence of the external excitation and the structural performance on the design structure.

The Analysis and Simulation of Cushioning Structure:

It will make the cushioning packaging products more economic and applicable to use the failure probability and reliability index of packaging products to characterize the capability of protecting products and the appropriate degree of cushioning package and to apply the probability method to design the cushioning package. By using more accurate dynamics analysis method such as finite element method, boundary element method, combining with the modal analysis and parameter identification technology, the acceleration response at any part of the product can be accurately analyzed and the local size of the buffer pad can be optimized, which can further improve the adaptability of the package to the circulation environment and reduce the amount of buffer material.

The Standardization of Shock-proof Packaging.

The existing packaging design lays more emphasis on the buffer and neglects the shockproof packaging. The six-step method of cushioning packaging proposes that the coordination of the shock and vibration should be taken into account. However, only the buffer design has standards to be referred to.

Research points:

The cushioning mechanism of laminated board.

The cushioning properties of honeycomb and corrugated board.

The new type of cushioning packaging structure.

The finite element analysis and optimization design of packaging drop.

The standardization of shockproof packaging.
