Like other materials, plastics have their own part to play in bakeries. They see use in the conveyor systems that automate food processing and cooking and in the general transportation of food. Food safe plastics such as UHMW that feature excellent chemical resistance are easier to sanitize than other materials and are in general more durable, making them an often superior choice when durability, lower maintenance, and part longevity are important.

Plastics see use in many aspects of the bakery industry. In the manufacturing process, several materials are used in the various machines and systems:
Outside of the manufacturing process, plastics such as polycarbonate and acrylic are used for commercial display stands in bakeries HDPE makes up a significant amount of cutting boards.
Materials for bakeries fall under NAICS #311811, 311812, 311821, and 333241 as well as SIC #2045, 2051, and 3556.
A variety of food grade plastics are available for use in the baking industry. From LDPE, PET, and polypropylene packaging to UHMW, nylon, and acetal parts for conveyor belt systems, plastics are used throughout the baking and bakery manufacturing process. In commercial bakeries, HDPE cutting boards provide a longer-lasting and more easily cleaned alternative to wooden butcher blocks, while plastics such as polycarbonate and acrylic are used in commercial display stands to hold and showcase baked goods.
The FDA does allow certain types of plastic, known as "food grade," FDA compliant, or food-safe plastics to come into contact with food. These plastics include UHMW, PEEK, PPS, PET, PTFE, HDPE, acetal, natural nylon, and polypropylene.
Polypropylene, PP, or reycling number 5, is a FDA-approved plastic that is safe for food contact. Polypropylene is BPA-free and has excellent chemical and moisture resistance. It's typically used in the food industry for food containers and jugs.
The most common plastics used in food packaging include PET, HDPE/LDPE, PVC, polypropylene, and polystyrene.
