    Materials We Limit - BPA-Free Plastics

    Plastics are man-made materials and in today's modern life are nearly unavoidable. Some are considered safe and others toxic, particularly when used to hold and store food & drink. We like to err on the side of caution so where practical we try to limit use of safe plastics in favour of materials like glass and stainless steel because they are safer for people and the planet in daily use and the manufacturing process.

    Safer plastics, namely BPA-free, PVC-free and Bioplastics, are generally considered eco-friendly and safe when used properly. Plastics are typically grouped into seven plastic recycling codes you can use to identify safe plastics and they are found on the underside of the bottle or packaging. Safer plastics are marked:

    • #1: PET (Polyethylene Terephthalate)
    • #2: HDPE (High-Denisity Polyethylene)
    • #4: LDPE (Low-Density Polyethylene)
    • #5: PP (Polypropylene)

    Importantly avoid plastics with the recycling code #3, #6, and some #7 (read more on these in our 'Materials to avoid').

    Also if you must use plastic to hold and store food there are also a few rules of thumb for proper use of safe plastics:

    1. don’t heat in the microwave
    2. don’t store fatty or acidic foods
    3. don’t used if scratched or worn, and

      After FIVE FULL YEARS OF USE, I needed to replace the lid and the insulated bag as my daughter had swing the handle off... I love that you can buy the replacement parts as needed. And now my niece has a Go Green Lunchbox to start her schooling years.

      I was waiting until I tried them before school as I was sceptical about things staying cold. Well after using them twice with different things I’m happy to be proven wrong. They are amazing, roomy and the girls absolutely love them. Definitely a worthy purchase:)
