Count on our materials expertise.

Packaging is all about function. And functionality depends upon the right material choice. Our industry-leading materials experts are ready to work with you to find the best material for your application. They evaluate new materials as they come on the market and can demonstrate the merits of every material used in packaging today. We’ll show you traditional plastics as well as next-generation, eco-friendly alternatives, including post-consumer recycled materials and resins derived entirely from plants, like our Greenware® products.

Whether you’re selecting a stock product or collaborating with us on a custom packaging solution, the experts at Fabri-Kal will put the depth and breadth of their knowledge into your best packaging answer — beginning with the right material.

Resin Code Description Properties FK Stock Product Applications
1 (PET) Polyethylene Terephthalate (PET, PETE, APET, RPET)

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.
Kal-Clear® Cups

Alūr™ Round Containers

Indulge™ Dessert  Containers
2 (HDPE) High Density Polyethylene (HDPE)

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 many 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.
Used mainly in custom packaging applications
3 (PVC) Fabri-Kal does not thermoform any PVC (Polyvinyl Chloride) products.
4 (LDPE) Low Density Polyethylene (LDPE) is used predominately in film applications due to its flexibility. Fabri-Kal does not generally thermoform LDPE (Low-Density Polyethylene) products.
5 (PP) Polypropylene (PP)

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.
Nexclear® Cups

Pro-Kal™ Deli Containers

Kids Cups
6 (PS) Polystyrene (PS)

PS is a versatile plastic that can be rigid or foamed. General purpose polystyrene 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.
Excellent moisture barrier for short shelf life products.

Significant stiffness in rigid forms.

RK Drink Cups

Juice Cups


Medicine Cups
7 (Other, PLA) Other

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