Is Plastic Labeled Number 7 Safe?

When you're holding a plastic container and see the number 7 inside the recycling symbol, it's natural to wonder about its safety. Unlike other resin codes, number 7 is a catch-all category for various types of plastics, including polycarbonate—often used in hard, clear bottles and food containers.

The real concern comes when that number 7 plastic also contains BPA (bisphenol A), a chemical linked to health issues when it leaches into food or drinks. If the label includes the letters “PC” (short for polycarbonate), it almost certainly contains BPA. But here’s the catch: not all manufacturers mark their products with “PC,” so you can’t always rely on that detail.

Even if the “PC” isn’t listed, a clear, rigid plastic with a number 7 could still be made from BPA-containing polycarbonate. That’s why experts recommend erring on the side of caution—especially when it comes to items used for storing food or beverages, like water bottles or baby bottles.

Over time, especially when exposed to heat or harsh cleaning, these plastics can degrade and release BPA more easily. While regulations have pushed many manufacturers to phase out BPA in favor of safer alternatives, the lack of transparency around labeling means consumers need to stay vigilant.

The safest approach? Avoid number 7 plastics when possible, particularly if they’re hard and transparent. Opt instead for plastics labeled with numbers 1, 2, 4, or 5, which are generally BPA-free and considered safer for everyday use. When in doubt, choose glass, stainless steel, or plastics clearly marked as BPA-free. Your health is worth the extra attention.
