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.

Resin Code


  • 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



Polypropylene has good chemical resistance, is strong, and has a high melting point making it good for hot-fill liquids. This resin is found in flexible and rigid packing, fibers and large molded parts for automotive and consumer products.

Resin Code


  • Easy to color or modify
  • High heat resistance
  • Steam barrier properties
  • Good impact and rigidity balance


Polystyrene is a versatile plastic that can be either rigid or foamed. General-purpose PS is clear, hard and brittle. It has a relatively low melting point. Typical applications include protective packaging, foodservice packaging, bottles and food containers. PS is often combined with rubber to make high-impact polystyrene (HIPS) which is used for packaging and durable applications requiring toughness, but not clarity.

Resin Code


  • Excellent moisture barrier for short shelf-life products
  • Low melting point
  • Significantly stiff in rigid forms
  • Low cost and easy to process

Polylactic Acid

Use of this code indicates that a package is made with a resin other than the six listed by the American Chemistry Council, or is made of more than one resin and used in a multi-layer combination.

PLA is made from lactic acid. Lactic acid is made from dextrose by fermentation. Dextrose is made from starch, and starch is produced from annually-renewable plant sources. PLA is clear and strong like petroleum-based plastic.

Resin Code


  • Strong and durable
  • Bioplastic that is made from lactic acid
  • Provides excellent product clarity
  • Potential to break down into nutrient rich soil

(Plant Fiber Blend)

Wheat Straw

Greenware Plant Fiber Blend Containers are made with wheat straw. Wheat straw is an annually-renewable resource that is leftover after the grain is harvested each year. There is no disruption to the food chain and no deforestation with products made from wheat straw. All wheat straw resources are farmed close to our manufacturing facility, reducing transportation and emissions and environmental impact.



  • Annually renewable natural resource
  • Naturally holds up to wet, heavy foods
  • Wide temperature range provides versatility
