Plastic pallets, although more expensive when compared to wooden ones, are slowly gaining acceptance due to their duarability, reusability and easily sterilizable surfaces. Plastics pallets are now marketed in number of millions. However, their share of the total pallet business is minuscule. One of the major constraint is that its cost that is almost 100 - 400% higher than that of wooden pallets. Of course, plastic pallets do offer advantages in terms of performance, aesthetics and environment friendliness as compared to wood. Plastic pallets can be manufactured by injection moulding as well as Thermoforming. Injection moulded pallets have better aeshtetics and show, better performance compared to the thermoformed products. However the injection moulded pallets are much more expensive. In thermoforming twin-sheet process is found to provide excellent performance. The US postal services have conducted an in-depth study of several types of pallets and have concluded that twin-sheet thermoformed pallets out perform all other types of pallets. Infact, they are only using plastic pallets for their postal systems. To reduce cost, attempts have been made to develop plastic pallets using recycled thermoplastics like HDPE/PP etc. There's however a niche market for plastic pallets. They are used in shipping of products since wooden pallets are not permitted by several countries.
