HDPE Plastic Food Container (#2)

USE WITH CAUTION

Storing dry goods, pantry staples, and meal prep at room temperature

Materials

  • High-density polyethylene (HDPE, recycling #2)

Common claims

  • BPA-free
  • Dishwasher safe
  • Lightweight

Concerns / watch-outs

  • HDPE is one of the safer plastics but can still leach additives at elevated temperatures
  • Avoid microwaving or storing hot food — cold and room temperature use is lower risk

Notes

Among the safer plastic types for cold food storage. Avoid heat and replace if cracked or scratched, as degraded surfaces leach more readily.

CLEAN & SAFE

Daily hydration and beverage transport

Materials

  • 18/8 food-grade stainless steel interior
  • Stainless steel exterior

Common claims

  • BPA-free
  • Double-wall vacuum insulated
  • Keeps cold 24h / hot 12h

Concerns / watch-outs

  • Some insulated bottles have plastic inner linings or lids; verify the interior is stainless
  • Avoid bottles with unknown coatings inside the bottle body

Notes

A top-tier choice for everyday hydration. The 18/8 stainless interior is inert and doesn't impart taste. Hydro Flask, Klean Kanteen, and S'well are popular brands with solid safety track records.
