Plastic trays are small platforms with raised plastic edges designed to prevent contents from rolling or sliding off the tray's surface. Designed for storage, display, transportation and organization, trays have become increasingly popular in several manufacturing fields, linked in large part to assembly and packing processes. They can be used in almost any manufacturing application because of their versatile design. A simple tray can incorporate clear panels to show manufacturer information or simply as part of a larger packaging solution.
Trays come in many shapes and sizes, including adjustable heights, widths, and shapes for liquid or solid contents. Trays are often coated with plastic or powder coatings to prevent moisture from penetrating the surface, but some plastic trays are uncoated and simply available as bare plastic. The material also can be printed on, allowing the use of bar coding or laminating. There are many different types of plastics suitable for use in plastic trays, including thermoplastic polyolefin (TPU), thermoform thermoplastic polymer (TFP), and thermoplastic rubber (TPE). The thickness of a plastic tray can vary from as little as.5 millimeters to as much as 3 inches.
Thermoplastic polyolefin is used to create plates, bowls and other common kitchen equipment, such as pizza pans, pie plates, cookie sheets and more. Because of its low cost, high strength and durability, it is widely used as a raw material. Because of this material's flexibility, it can be easily imprinted with decorative designs that can add variety to kitchen or office equipment. Thermoplastic polymer is FDA approved and comes in a wide range of thicknesses, colors and surface textures, and has anti-fungal properties that make it safe for use in cosmetics and cleaning supplies. TPU is dishwasher safe and most manufacturers offer a lifetime warranty against breakage, cracking or shrinkage.
Other thermoplastics are also available and are made from materials that are even more durable and appropriate for use in food preparation. Common materials used in thermal trays include PTFE, Teflon, and thermoplastic rubber. These materials can withstand high temperatures ranging from temperatures as low as -423 degrees Fahrenheit to temperatures as high as 450 degrees Fahrenheit.
Thermoplastic trays make food preparation easier and less messy. They are useful in cold, refrigerated and hot settings and come in a variety of sizes and shapes. Trays come in colors that coordinate with individual dishes, making them easy to match with kitchenware and utensils. Since the trays do not retain foods or liquids, they eliminate clean up and sanitizing. They are also resistant to scratching, peeling, chipping and tearing and come with a long life span that makes them an economical and versatile choice.
Plastics have come a long way in their development and use. Manufacturers are continually working to make products that are safer for consumers. Plastic trays are just one step along the way.
