(PET) Polyethylene Terephthalate

PET is clear, tough, and has good gas and moisture barrier properties.

This resin is commonly used in beverage bottles and consumer product containers.
Cleaned, recycled PET flakes and pellets are used for spinning fiber for carpet yarns, producing fiberfill and geo-textiles.

  • Clear and optically smooth surfaces

  • Excellent barrier to oxygen, water, and carbon dioxide

  • High impact capability and shatter resistance

  • Excellent resistance to most solvents

  • Capability for hot-filling

(HDPE) High Density Polyethylene

HDPE packaging generally is translucent, has good barrier properties and stiffness, and is well suited to products with a short shelf life such as milk.
Because HDPE has good chemical resistance, it is used for packaging household and industrial chemicals such as detergents.

  • Excellent resistance to most solvents

  • Higher tensile strength compared to other forms of polyethylene

  • Relatively stiff material with useful temperature capabilities

(LDPE) Low Density Polyethylene

LDPE (low density polyethylene) is a soft, flexible, lightweight plastic material. LDPE is noted for its low temperature flexibility, toughness, and corrosion resistance. It is not suited for applications where stiffness, high temperature resistance and structural strength are required. It is often used for orthotics and prosthetics. LDPE has good chemical and impact resistance and is easy to fabricate and form.

(PP) Polypropylene

PP has good chemical resistance, is strong, and has a high melting point making it good for hot-fill liquids.

  • Good optical clarity

  • Low moisture vapor transmission

  • Inertness toward acids, alkalis and most solvents
