Common uses: 2-liter soda bottles, single-use water bottle containers, cooking oil bottles, peanut butter jars. This is the most widely recycled plastic
Commonly recycled, PET is semi-rigid and very lightweight. It's best suited for single-use containers as it can break down when exposed to light and heat, causing it to leach. PET can also be recycled into fabric, similar in strength and appearance to virgin nylon.
Common uses: detergent bottles, milk jugs.
HDPE is a sturdy and reliable non-leaching translucent plastic. HDPE resists UV penetration, which can damage and discolor the plastic. Dishwasher-safe and able to withstand temperatures from -148 to 176° F (-100 to 80° C), it's ideal for beverage and food storage.
Common uses: plastic pipes, outdoor furniture, shrink wrap, water bottles, salad dressing and liquid detergent containers.
Most PVC vinyl products contain phthalates, which mimic human hormones and also affect various life forms including fish and invertebrates adversely. For this reason, we do not recommend products made from PVC for food storage.
Common uses: dry cleaning bags, produce bags, trash can liners, food storage containers.
LDPE are safe, non-leaching plastics. Flexible, impact-resistant and microwave-proof, it's dishwasher-safe and able to withstand temperatures from -148 to 176° F (-100 to 80° C). Safe for use with food and beverages.
Common uses: bottle caps, food containers, drinking straws.
BPA-free, polypropylene is commonly used for injection molding. Its resistance to high heat generally makes it microwave and dishwasher safe, as well as a good option for reusable bags and food and beverage storage.
Common uses: packaging pellets or "Styrofoam peanuts," cups, plastic tableware, meat trays, to-go "clam shell" containers.
Polystyrene foam is a major component of plastic debris in the ocean, where it becomes toxic to marine life. Currently, the majority of polystyrene products are not recycled. This material should be avoided.
Common uses: LEXAN, certain kinds of food containers and Tupperware. This plastic category, as its name of "other" implies, is any plastic other than the named #1-#6 plastic types. These containers can be any of the several different types of plastic polymers.
Polycarbonate is the most commonly-known #7 plastic. Proven to leach BPA, it is not recommended for food storage. Not all "other" plastic is polycarbonate, however. Plastics labeled #7 can also be a combination of several safe plastics. Individual research should be done when making decisions about #7 plastics.

Tritan is the brand name for copolyester, a tough, BPA-free material that has similar properties to common plastics such as polycarbonate. Tritan has chemical resistance and maintains its integrity in environments where other materials may degrade. Products made from Tritan can have the look of glass—without the weight and with more durability.
Is Tritan considered a safe plastic?
Extraction tests completed by independent 3rd party researchers, verify that Tritan meets all requirements as set forth by organizations such as: FDA food safety standards, European Community food safety standards, Japanese Ministry of Health and Welfare, California Prop. 65. CamelBak has verified that all materials used in the bottle including Tritan meet the stringent guidelines set by California Proposition 65. In addition, after rigorous third-party testing of the BPA-free Tritan bottles, no harmful chemicals were detected to come in contact with or leach into food/beverage surfaces. A FCN (Food Contact Substance Notification) notice #729 declared that Tritan is safe and meets all EPA and FDA guidelines for material that is to come in repeated contact with food.
Our customers have been requesting Tritan products like CamelBak and Nalgene bottles for a while, but we wanted to make sure Tritan was safe before deciding to carry it. Based on our research, third party test results released and confidence expressed by other leading organizations and retailers, we believe Tritan is a safe alternative for manufacturing bottles, utensils and food containers.
