HDPE as a FDA approved cutting board
Next time are going to be slicing produce on your own slicing board, take the opportunity and check out it, the material most likely to be used as a High Density Polyethylene Cut Grade Material - Sheets cutting board is Polyethylene. Simply because it is normally FDA and NSF approved as well as stain, moisture and odor resistant, Polyethylene is the perfect choice for slicing boards.
Other types of cutting boards constructed from wood are susceptible to bacteria and long term odors because they lack the sought afterproperties that Polyethylene sheets offer, including its non porous surface, chemical resistance and approval for food contact. Polyethylene material is certainly a durable and lighter weight material that comes in many forms and is designed for a wide array of applications. There are numerous kinds of Polyethylene commercially available. The most typical are HDPE (High Density Polyethylene), LDPE, and UHMW (Ultra High Molecular Weight Polyethylene). The only difference has to do with the molecular weight and branching; which is when a monomer or atom is replaced by a longer chain of polymers (a very long repeating chain of atoms).

High Density Polyethylene is normally used for milky white gallon milk jugs and Tupperware style food containers. Low Density is usually used for bottles and plastic sandwich bags. UHMW, which has higher molecular weight (2-6 million) which enables for an even transfer over the length of material which makes it stronger, so that it is able to be used with regard to bearing job applications because of the great wear resistance. Commonly utilized in the food processing and dairy industry, Ultra High Molecular Weight Polyethylene is a nice replacement for numerous industrial materials along with fantastic method to fix many wear issues. Every one of those polymers are derived from the same polyolefin plastic family, but they all have certain properties that make them a little different. HDPE provides great chemical resistance, has higher impact strength and great energy absorption. Low Density Polyethylene has lots of of the same properties as High Density but it is not as dense at 9.15, instead of HDPE which happens to be 9.34, and it's also a softer material ( flexible coffee can lids). In addition it provides a lower tensile strength and greater, simpler and easier heat forming.
UHMW is a strong material that possesses great durability and low co-efficient of friction making it an ideal for sliding applications. The only plastic material with a lower co-efficient of friction is Teflon - PTFE; which has a higher temperature and chemical resistance. Ultra High Molecular Weight Polyethylene has a wide variety of material choices and properties, and these types of materials possess remarkable toughness which could be suitable for a number of applications. From the food industry to automotive, the kitchen or maybe the warehouse, whatever your Polyethylene needs are - High Density, Low Denseness or UHMW, Polyethylene is a great decision.
