Sandwich panel is a new construction material composed of three layers of materials. It is mainly used in projects that require high structural stiffness and low weight. The structural function of a sandwich panel is similar to that of a classic I-beam, where the two panels primarily resist in-plane and transverse bending loads, while the core resists primarily shear loads. It adopts the new technology concept of using a light/soft but thick material layer as the core of the board and a strong but thin layer as the panel. This allows the overall thickness of the panel to be increased while maintaining or even reducing the weight of the panel, which also improves structural properties such as bending stiffness. The strength and lightness of this technology make it widely used.


From factories to stadiums, shopping malls to swimming pools, sandwich panels are a durable and economical choice for many buildings. The advantages of sandwich panels include the following:

1. Quick and easy installation;
Sandwich panels are highly compatible and can be produced in the required sizes and ready for assembly based on the structure of your facility. The installation is very simple, shortening the transportation and installation time, and can complete the project delivery in a short time.
2. Perfect thermal insulation performance;
Sandwich panels are a building material excellent for thermal insulation. It offers high thermal insulation properties with PUR, PIR, EPS and mineral wool insulation. Reduce the energy required for heating in winter and cooling in summer and provide a comfortable living environment.
3. Economical;
Sandwich panels are not only cheap but can be disassembled and reused. When frequent relocation and reconstruction are required, repeated construction and economic waste can be greatly reduced.
4. High fire resistance;
Some sandwich panels use fire-resistant materials as internal filling materials. Sandwich panels with fire-resistant and heat-insulating properties can slow down the spread of fires in and around the building. Provide more valuable time for escape and rescue.
5. Obvious noise reduction effect;
Acoustic sandwich panels feature a mineral wool insulation core and a perforated metal sheet surface for significant sound insulation. If you use soundproof sandwich panels on the roof and walls, you can create a healthy and comfortable noise-free space that makes people feel happy.

About the packaging of sandwich panel, it seems to be a problem for the manufacturers. This is because the sandwich panels usually are in very large sizes. It's difficult to realize good wrapping both by manual wrapping or using wrapping machines. Emanpack has been dedicated to the development of automatic wrapping machines for sandwich panel industries. Our Orbital stretch wrap machine HM-A1800 has its turing ring made up to 3 meters to match with the big bundles of sandwich panels. With top film dispenser, this horizontal wrapping machine is also available to cover the bundle with a layer of plastic film before the stretch wrapping. To realize the full sides sealed packaging for sandwich panels.
