Where there is no “standard poly” as one might say, there are over a hundred possible variations on polyethylene resins that can be used. Each is engineered for a different end use. From a gallon milk jug to bread bags each has a very different use, but all using Polyethylene.
Some of the most common forms are: High Density Polyethylene (HDPE), Medium Density polyethylene (MDPE), Low Density Polyethylene (LDPE), Ultra Low Density Polyethylene (ULDPE), Metallocene, Fractional Melt, and Very Low Density Polyethylene (VLDPE).
With so many potential variations of Polyethylene film we can work with you to define your options for your next project, all while giving you the option of having us hold Inventory for you. Below are some of our offerings and where they are commonly used. Please contact us for just a quick question or to discuss your new project - we are listening!!

This a machinable thermoplastic known for its high strength to density ratio, light weight, long term durability is one of the most widely used plastics. HDPE is high impact, will not splinter or rot, has very high impact strength, abrasion, stain, moisture and odor resistance. Many grades are FDA approved for food processing industry. HDPE has a low coefficient of friction and can be easily cut, welded, thermoformed and machined. Moisture and water (including saltware) have no affect on HDPE. It can be used totally submerged in saltwater or freshwater.
HDPE is stronger and stiffer than LDPE but its impact strength is not as good at low temperatures. Also it is known to warp due to its high crystallinity. HDPE has a higher shrinkage thank LDPE. HDPE has poor UV resistance. When high heat is used dangerous fumes are produced.
A big use of HDPE currently is recycling it by turning it into a Wood-plastic composite.
Plastic Film Additives and Treatments To The Film
- Flame retardant – additive compounds to render a polymer fire resistant
- Color Pigments – color pigment concentrates that can be added
- Carbon Fillers – high concentration results in conductivity of the film
- UV Stabilizers – added to resist sunlight
- Slip/Anti-block Agents – added to improve film to film slipping and blocking
- Anti-Static – resistance to static buildup
- Silicone coated
- Corona treated
