Stackable trays are compared in areas such as usage, including food service and storage; and material, including the differences or similarities between trays made from melamine, polycarbonate, polypropylene, acrylonitrile butadiene styrene and a co-polymer blend. Other details of plastic trays that are comparable to one another are temperature tolerance, stain resistance, durability and usage options.
Stackable trays made of melamine are durable and stain-resistant. Melamine is able to withstand temperatures ranging from 0 to 212 degrees Fahrenheit. Both food service and storage trays made of this material are dishwasher safe, but melamine should not be used in microwaves. Melamine bowls and household storage trays are offered in a variety of colors and patterns.
Polycarbonate is moderately stain-resistant and has a high resistance to breakage, but it scratches easily. Stackable trays made from this material are used in food service or household storage. Polycarbonate trays withstand temperatures from -40 to 212 degrees Fahrenheit, making them ideal for use in freezers, dishwashers, microwaves and other low-temperature and high-temperature atmospheres.
Stackable trays made from polypropylene are virtually stain-resistant and have very low rates of breakage and scratching. These trays can be exposed to temperatures between 32 and 180 degrees Fahrenheit, making them microwave and dishwasher safe. Food service establishments tend to use polypropylene trays over melamine because the material offers comparable durability at a lower cost.
