Shock-absorbing packaging is used to protect products from blows, impacts, and vibrations during transport and handling. The foam’s purpose is not merely to create a soft layer around the product. It needs to slow down the movement and absorb energy before the force reaches the part that needs to be protected.
At Cabseal, we manufacture shock-absorbing packaging made of polyether foam, polyester foam, cellular polyethylene, and PE-Layer. The material, thickness, and design can be customized based on the product’s weight, geometry, and fragility, as well as how the packaging will be used.
Right from the startProper shock absorption involves more than just a thick layer of foam
When a packaged product is subjected to an impact, the foam compresses and slows the product’s movement. If the material is too soft relative to the product’s weight, it can compress so much that the product effectively breaks through the protective packaging. Conversely, a material that is too stiff may transfer a larger portion of the impact to the product.
Therefore, the material’s density, hardness, and thickness must be evaluated in conjunction with the load the packaging is intended to bear. The contact surface also plays a role. A heavy product resting on just a few small surfaces exerts a different load on the foam than a product whose weight is distributed over a larger surface area.

The Right Foam Material for the Right NeedDifferent foam materials provide different types of protection
Polyether and polyester foams are flexible foam materials that can be used to wrap products and create shock-absorbing inserts. These materials can conform to complex shapes and are ideal when packaging needs to combine protection with flexibility.
Cellular polyethylene has a denser cell structure and provides firmer protection with low water absorption. The material is useful when packaging needs to be more dimensionally stable or withstand repeated handling. PE-Layer can be built up in multiple layers, making it possible to create thicker packaging components and adapt the design to the product’s shape and the desired level of protection.
Cut-out inserts keep the product in place
Effective transport protection should not only absorb an external impact. The product also needs to be held in place so that it cannot shift and gain momentum inside the packaging.
By shaping the foam to the product’s contours, we can create inserts with custom cavities, recesses, and support points. This allows sensitive parts to remain exposed while securing the product where it can best withstand stress. For other applications within the same material group, you’ll find additional solutions among our foam plastic products.
