Why we list this: Plastic food containers leach at measurable levels into food, especially when heated. Glass is the only material that leaches nothing — Weck uses glass lids too, eliminating all plastic contact.

Key features

  • Borosilicate glass — completely inert, no leaching
  • Rubber seal and glass lid — no plastic contacts food
  • Microwave, oven and freezer safe
  • Made in Germany since 1900
  • Reusable indefinitely — replaces single-use plastic containers
