Have you ever wondered how it is made the basic thing that you use in transporting your products? Protective foam packaging has a lot of things in its composition that makes it so good in protecting objects.
By understanding the physical issues and the basic terminology related to Polyurethane foam, it can be specify the appropriate protective flexible foam product for the individual packaging application. Whether you need to protect a heavy piece of equipment, or a delicate electronic component, the performance of polyurethane foam can be fine-tuned to meet most packaging needs. Industry sources suggest that flexible polyurethane foam can surely absorb impacts efficiently and recover its physical shape fast, and repeatedly.
It is appropriate for packaging fragile items with a wide range of weights and sizes. In addition, flexible foam can easily be cut and shaped easily for bracing, supporting and wrapping objects. Two basic properties of flexible foam polyurethane foam are the keys to packaging performance. Density is the weight of a cubic foot of foam and is an indication of the amount of material available to absorb energy. Density is independent of firmness. More than that, a high density foam will be better able to stand up to repeated impacts without its cushioning characteristics to be affected. High density foam with high energy absorption capability can have a very soft and conforming surface, or, if not, it can be produced to be very firm and not so conforming. Density adds an important aspect to foam specification. Foam thickness is not the only energy absorbing consideration. For heavier objects, or in shipping conditions, where great shocks are anticipated, higher density thicker polyurethane foam materials may be appropriate. Since higher density flexible foam absorbs energy efficiently, there may be opportunities to optimize packaging space to reduce the entire shipping size. Do not worry; your foam supplier can help you select a good thickness and foam density to serve all of your objectives.
In specifying flexible foam for packaging, the foam supplier plays an important role, helping to calculate the cushioning requirements for various. When consulting a foam supplier, two pieces of information are vital to engineering a proper packaging solution: the fragility of the product to be protected at the maximum drop height products, and sharing information on foam properties including physical performance capabilities, anti-static characteristics and recycling. Besides the fragility index, the maximum drop height must also be established for an item to be packaged. Maximum drop height is nothing more than how far the packaged item is expected to be dropped during typical handling and shipping procedures. Once the maximum drop height and fragility index are determined, the packaging engineer uses dynamic cushioning curves for various packaging materials to design a protective package.
New technologies are being developed to help combine the good properties of flexible polyurethane with the static loading capability of the thermoplastic foams based upon a visco elastic model. That way, the static load limit for flexible polyurethane foam can be more than doubled.
Foam is not the best option for every kind of packaging, but, for fragile objects, the best method of transporting them safely, is protective foam packaging, for sure.
