Learn more about the materials used to construct drinkware.

A lightweight alternative to stainless steel; the look and feel of a metal vessel without the premium cost and heftiness of steel. This material is more widely accepted in recycling programs.

Usually referred to as #7 AS, Acrylic is a rigid plastic material. Acrylic is used on tumblers and bottles, as well as for lids and outer straws.

Stoneware molded and fired in a kiln, perfect for hot beverages. Shipping usually requires more packing material to prevent this fragile material from breaking.

Chemically inert and recyclable, glass is a great eco option. The disadvantage is its fragility, making it one of the least versatile drinkware materials.

also known as 304 grade, 18/8 steel is the most widely used form of food-grade steel. 18/8 represents the composition: 18% chromium and 8% nickel.

Copolyester plastic that's manufactured by Eastman Chemical Company. Made without any BPA, Tritan is strong, clear, and resistant to heat and chemical degradation. It's also impact-resistant, so products can be used without fear of shattering.

Tritan Renew is the same tough, safe, BPA-free material as Tritan — but revitalized thanks to Eastman’s innovative recycling technologies, containing up to 50% certified recycled content.


Referring to Bisphenol-A, an industrial chemical used in the manufacturing of some plastics, BPA-free refers to the absence of Bisphenol-A to address safety concerns that have come up in the last several years regarding the use of this chemical. All plastics used on PCNA drinkware are BPA-free.

  • Chug – Usually refers to a wide mouth bottle that allows the consumer to take larger drinks of their beverage, such as large gulps of water.
  • Sip – Drinkware with straws or smaller openings that encourage smaller sips, such as small sips of hot coffee.

Spray painted exterior with a shiny appearance, usually on Good drinkware styles.

Spray painted exterior with a flat or almost dull appearance. Also on Good drinkware styles.

Powder coating is a protective and durable finish that is applied to the exterior of metal drinkware vessels. The powder itself is a mixture of polyester resins, curing ingredients and pigments. More environmentally friendly than traditional painting with less waste, no overspray, and no solvents. Powder coating is done in a specialized oven, a chemical reaction occurs that effectively “cures” the powder and creates a super durable finish. Best drinkware styles offer this finish.

California Proposition 65, also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, Prop 65 is an initiative to reduce human exposure to toxic chemicals. The State has published a list of over 950 naturally occurring and synthetic chemicals that are known to cause cancer, birth defects, or other reproductive harm. All of our drinkware at PCNA is confirmed as Prop 65 compliant.
