HDPE is much more rigid with almost four times the tensile strength of LDPE.  It meets the same FDA requirements of LDPE and is USDA approved for use in meat and poultry packing facilities.  It is available in sheets, rods or tubes.

HDPE has excellent impact strength, low moisture absorption, chemical-corrosion resistant and odor resistant.  It is lightweight, non-toxic and non-staining.  

Here at Royal, HDPE is an excellent choice of material when working with the food processing industry. We regularly machine/fabricate trays, cutting boards, cheese molds, plastic cutting tables, blade trays and so much more.

Just to name a few of the numerous parts that Royal has produced for the industrial equipment industry using HPDE are:   water tanks, chute linings, segments, supports, plastic carts and pallets.


Heat & Chemical Resistance

It can withstand temperatures up to 230 degree fahrenheit and is resistant to mild acids and solvents.


Mechanical properties

HDPE is used for the largest portion of polyethylene applications, and has much more rigidity and tensile strength than LDPE, but impact strength is slightly lower due to its stiffness. Overall, HDPE offers excellent impact resistance, is lightweight, has low moisture absorption, and has high tensile strength.



HDPE is rated HB
