High-density Poly Ethylene also is known as HDPE is made from a cord of ethylene molecules (the poly part of polyethylene), and is famous for its light weight and high durability.
The preference of HDPE sheets is increasing from leaps and bounds in the market today, as it’s able to cut down on the material which is then used for producing and packaging products for its strength and weight.
It is also available at tap plastics in sheet form with either a smooth or textured surface. The textured surface is also called cutting board. Both smooth and textured surfaces are FDA approved for food contact.
Types of HDPE Sheet
HDPE sheets are expanded into multiple types, each type has different applications and uses such as;
HDPE Matte Sheet
HDPE sheet comes with a textured surface which is also known as HDPE Matte sheet. This type of sheet is designed to produce items like cutting boards. HDPE Matte is acid resistant, reliable with FDA controls, and certified by the National Sanitation Foundation (NSF).
It is best for food preparation as it won’t make your knives dull, and it doesn’t harbor bacteria as well.
HDPE Smooth Sheet
Smooth HDPE sheeting is ideal for those applications which need good abrasion resistance and low friction. It comprises of multiple features which make it versatile for many applications. The best, yet the most common example of smooth HDPE sheet application is, tank linking.
Smooth HDPE is effortlessly created and includes great compound protection, elasticity, and is dampness and effect safe.
HDPE Pipe Grade
This kind of HDPE plastic sheet features more advance performance than standard HDPE sheeting. The enhanced highlights of HDPE pipe grade make it the most well-known HDPE sheet for open air applications.
