Which plastic are you drinking from? SPI Codes 1-7

Ever wondered what the numbers under plastic bottles and containers mean? We explore what the SPI (Society of the Plastics Industry) code 1 to 7 refer to.

Drinking from plastic bottles can have a negative impact on your health as plastic can sometimes leach chemicals into foods or drinks (even if the plastic is BPA – Bisphenol A).

    I ordered water bottle and I ask my seller and he replies me the following message. So what you think is that safe???

    We use the eco-friendly material Tritan, which is better than PP material, BPA Free, please rest assured to buy it.

    can you explain to me why the #2 plastic leaves behind a plastic taste yet the #1 does not? specifically talking about #2 gallon water jugs in comparison with jugs made from #1

    El envase de cristal/vidrio es el mejor hasta que se rompe y te cortas los dedos 🙂

    Is #7 plastic safe if it is in an opaque bottle? I read that and was curious because I found a probiotic I was interested in but it has #7….i asked them about it also and they said the inside is lined with desiccant?

    Since learning about plastic toxicity, I no longer refill my water bottles, I just get a new bottle of water or use glass like the VOSS bottles.

    I use a bottle that has 1 on it but also “BPA free” so is it safe? And its a reusable one it’s a hard plastic

  17. Enoch Jimenez on June 14, 2020 at 9:54 am

    My gallon jugs for my water dispenser is 7. Is that bad?

  18. Soul Alchemy on June 14, 2020 at 9:56 am

    And also can you suggest any brand for glass bottles.
    That’s durable.

    I notice alot of these videos don’t bring up gallons of water like one I buy from Kroger it has a 2 hdpe on it

  23. Cheeze Ballz on June 14, 2020 at 10:12 am

    I have a 1(pet) but next to the sign says bpa free, im confused, what should i do?

  24. j7ndominica0 on June 14, 2020 at 10:15 am

    Most important use for these codes is chemical compatibility with cleaners like acetone, alcohol or lye (there are tables for reference). A whole bunch of plastics are lumped into the other category, most of them are incompatbile with acetone. CDs are made from polycarbonate. Appliances are made out of ABS and can be damaged by spilled hygiene products containing solvents. Acrylic is damaged by alcohol and ammonia. (acrylic, pc, ps look similar)

    PET is mostly inert and has good compatibility. Hmm, if I keep the bottle in a cabinet or fridge and drain it slowly over half a year, it is still a "single use" of it. : )
