Polystyrene - Foamed

Probably the most versatile of substrates, foamed polystyrene may be made into a multitude of shapes and configurations. It has excellent insulation properties and decent thermal resistance making it applicable for both hot and cold foods. Hot foods will stay hot longer and cold foods will stay cold longer in a foamed PS container. Foamed polystyrene also takes very little energy to produce compared to other substrates and consumes virtually no water during production. It is also extremely light weight compared to nearly every other material which means it uses far less raw materials. As with many food packaging items, very few facilities exists for recycling, but recently there has been a surge in centers collecting this material. Check with your local municipality to see if a site exists near you.

PET - Polyethylene Terephthalate

PET is a solid plastic material most often used to produce water and soda bottles. APET is a crystal clear material and is an excellent choice when displaying food items. APET may also be used in cold and frozen applications as well and will hold up in automated fill/seal process lines. APET is #1 recyclable material.


When microwave safe options are required for food packaging, polypropylene is the best choice of materials.

Harvest Paper

Our paper cone, portion and drink cups are produced from raw materials originating from forests managed with Sustainable Forestry Practices and are all industrial compostable. All of our Harvest Paper product configurations are engineered for maximum strength and durability utilizing box pleats, concave surface areas and rolled rims.

Harvest Fiber

Genpak Harvest Fiber material is manufactured from renewable resources. The base fiber material for all of our products is bagasse, which is a byproduct of the sugar industry. Harvest Fiber products are microwave safe and grease & water resistant. Each item is engineered with ease of use in mind.

Foamed Polystyrene Facts

Foam packaging is 98% air! Polystyrene feedstock is converted into a finished product that is 32 times its original volume virtually turning air into a strong and efficient packaging material. Polystyrene is an efficient material to manufacture using minimal resources to produce a finished product.
