Low Density Polyethylene (LDPE)
LDPE film is an abbreviation for low density polyethylene film. LDPE Bag is great for its great tensile strength, clarity, flexibility and water barrier. It is also resistant to most caustic compounds. It also provides the following benefits: high quality packaging at a low cost, quick lead times in manufacturing, a variety of printing options.
High Density Polyethylene (HDPE)
HDPE film is often used in many of the same applications as LDPE and LLDPE and in some cases it is blended with LDPE to modify its properties. HDPE is well suited for applications where a greater tensile and compression strength is needed and/or when higher stiffness and rigidity is required. Like LDPE, HDPE possesses excellent impact strength and corrosion resistance.
Due to the low odor, high chemical resistance and inertness, many HDPE grades are suitable for packaging applications under FDA regulations. Due to the high boiling point, many grades can be sterilized in boiling water.
Typical HDPE film applications include bags; liners; food and nonfood packaging; agricultural and construction films.
