What is HDPE?
High Density Poly Ethylene (HDPE) is known for its large strength-to-density ratio. Besides cutting boards, this characteristic makes it preferable in a number of unexpected applications like tubing for pyrotechnics, and the fabrication of milk jugs by way of blow molding. Besides its use for food applications, it can be found in unusual places, including,
- Wood plastic composites,
- Plastic surgery, specifically skeletal and facial reconstruction,
- Shoe lasts,
- 3-D printing filament,
Industrial-grade, FDA, NSF, and USDA-approved food-quality High Density Polyethylene (HDPE) boards are engineered to be low maintenance, safe and long lasting. Their textured surface provides a grip to hold food safely. Additional benefits include all of the following:
- Chemical and corrosion resistance
- High impact strength
- Minimal moisture absorption
- Excellent resistance to acids, alcohols and bases
- Excellent long term durability
According to one report,
Nonporous surfaces like plastic or glass are easier to clean than wood and thus better in terms of food safety. Wood is naturally porous, and those tiny fissures and grooves in wooden cutting boards can harbor bacteria. Which is why cutting boards made of wood aren't allowed in commercial kitchens.
