Glass/Silicone use instructions
Glass Containers Glass containers and silicone sleeves are oven safe up to 425 degrees, microwave safe (remove lids before placing in oven or microwave), and dishwasher safe (top rack). Although our lids are dishwasher safe, research has shown that it is best to keep plastics out of high temperature environments like microwaves and dishwashers. Silicone grip helps prevent breakage and protects hands from hot surfaces, but as with any glass product or hot surface, use common sense when heating, storing and handling and avoid extreme temperature changes (freezer to oven, for example) that will crack the glass. Handle with care when using as bakeware. Silicone sleeve adds protection, but does not guarantee against breakage.
Glass Bottles As with any glass product, use common sense when handling and avoid extreme temperature changes that will crack the glass. Handle with care when filling with hot liquids. Not intended for use in oven, microwave or freezer. Care should be taken to make sure bottle is not dropped or knocked over, especially near the mouth of the bottle where exposed glass is not protected by silicone. Best to keep cap in place when not in use. The silicone sleeve adds protection, but does not guarantee against breakage. Glass bottles and silicone sleeves are dishwasher safe (top rack). Although our lids are dishwasher safe, research has shown that it is best to keep plastics out of high temperature environments like microwaves and dishwashers.
Plastic numbers explained
We use PET #1, LDPE #4 and PP #5 plastics in our products. We advocate for using plastic safely (not microwaving or heating), and getting to know your plastics. There are possible health risks with some types of plastics, so we only use plastics that are safe for food storage. All of our products are tested free of BPA and phthalates.
#1 - PET or PETE - polyethylene terephthalate is used in many water and juice bottles. It is commonly recycled, and accepted by most curbside programs and recycling centers.
#2 - HDPE - high-density polyethylene is common in milk jugs, detergent and shampoo bottles. It is usually accepted by most curbside programs and recycling centers.
#3 - PVC - vinyl or polyvinyl chloride is a known human carcinogen, often contains phthalates and is not recyclable. Phthalates add flexibility and durability to PVC and vinyl. They are present in products like toys, food packaging, plastic wrap, shower curtains, lotions, perfume, air fresheners and candles. Phthalates are listed as reasonably anticipated to be a human carcinogen by the National Toxicology Program, and are considered a probable human carcinogen and endocrine disruptor by the EPA. Even though phthalates have been banned from some baby toys and baby gear, they are still allowed in lunch bags and food containers, so always choose phthalate-free.
#4 - LDPE - low-density polyethylene is common in plastic bags, cling wraps, baby bottles and reusable drink and food containers. It is recyclable at most recycling centers and some curbside programs.
#5 - PP - polypropylene can be found in baby bottles, yogurt containers, and many reusable food and drink containers. It is recyclable in some curbside programs and most recycling centers.
#6 - PS - polystyrene is used in takeout food containers, Styrofoam containers and cups, and plastic cutlery. It has been found to leach styrene, a neurotoxin and possible human carcinogen, and has been banned in many U.S. cities. It is not easily recyclable.
#7 - This catchall category includes polycarbonate which has been found to leach bisphenol A (BPA), a hormone disruptor that mimics estrogen. Bioplastics (plant-based) are also in this category but cannot be recycled and are usually sent to landfill unless directed to a bioplastic-specific composting facility.
Insulated containers keep food and beverages hot and cold
Our stainless steel Insulated Containers keep food and beverages hot or cold for several hours. They're designed to keep the temperature you start with, so pre-heat by pouring very hot water inside and letting sit for a few minutes before pouring out and adding your piping hot food, and pre-chill in the freezer for a few minutes (lid off) before adding your cold food.
Food Kozy materials
We use LDPE #4 plastic for our Food Kozy Wraps and Snack Bags. Why plastic? Our customers tell us that they like the non-fabric solution because it is easier to clean, dries quickly, keeps food from seeping through, and the slick surface is perfect for messy foods. The plastic surface also makes an ideal placemat.
Our products are designed in California, and responsibly made in China and Taiwan in facilities that are working toward green practices and supportive of our mission to reduce waste.
All Stainless Steel Containers, Glass/Silicone Containers and Bottles, Stainless Steel Accessories, Food Kozy Wraps and Bags, and Bamboo Utensils are made in China. Our recycled insulated fabric (used in our Insulated Lunch Totes and Ice Packs) is made in Taiwan.
