The typical bakery tray used in the baking business is either metal or plastic. When it comes to the latter, a material known as high-density polypropylene (HDPE) is used to manufacture these trays. Part of the polypropylene family, HDPE earns its name due to its unique molecular density, which gives it some incredible properties. A few significant properties of this material will be discussed here.

5 unique properties of high-density polypropylene that’s used in bakery trays:

Corrosion Resistance

It is not uncommon to see a metal tray or rack getting discoloured after prolonged use, courtesy of chemical corrosion. However, with HDPE, that is not a problem as these plastic trays can withstand corrosion with ease. Thus, food products and chemicals of varying pH levels can be stored in containers made of this robust material.

FDA Approved

The Food and Drug Administration (FDA) is the ultimate authority on determining the safety of food, medical, cosmetic and other biological products in North America. Since HDPE is non-corrosive, it has been approved by the FDA as a safe storage option for food products. Thus, you can use your plastic bakery tray with no qualms. 

Extremely Tough And Light

Aluminum, considered to be one of the lightest metals, has a density of 2699 kg/m3 (0.0975 lb/cu in). In comparison, HDPE’s density is just 965 kg/m3 (0.0348 lb/cu in) at most, making it one of the most lightweight yet durable materials on the planet. 

UV Resistant

Sunlight can often deteriorate the quality of a product, especially if it is exposed in the open for too long. However, with HDPE there are no such problems. Hence, quality plastic trays, such as those made by D & V Plastics, can be used in indoor as well as outdoor spaces. So if you are organizing or managing an open-air catering event, then don’t hesitate to store your baked goods atop these trays.

Moisture Resistant

One of the leading causes of corrosion in metal products is moisture, which strikes the material sooner or later. HDPE on the other hand has zero moisture absorption properties, making it one of the best materials to build hold storage tanks for water and other liquids. Ultimately, products made from HDPE will not absorb moisture even after staying in contact with a liquid for a prolonged period of time. 

Thanks to these 5 benefits, it is obvious that HDPE is the primary choice when it comes to plastic trays.
