Where plastic hides in food storage containers

"Glass" and "stainless" describe the box and say nothing about the lid. On most glass sets the lid is polypropylene with a silicone gasket and nylon or polypropylene latches. Stainless containers seal with a silicone ring. Metal screw lids on jars carry an inner lacquer and a sealing compound that is commonly PVC plastisol. "BPA-free" means the plastic was reformulated, not removed. Read the lid, the gasket and the latch before the jar.

What to check before you buy

  1. The lid: steel, wood or glass, or polypropylene?
  2. The seal: natural rubber, cork or steel on steel, or silicone?
  3. The latches and hinges: metal, or nylon and polypropylene?
  4. Jar lids: bare steel, or a lacquer lining and a plastisol compound?
  5. The print on the body: fired or etched, or a plastic ink?
  6. Packaging: paper and card, or shrink film and plastic dividers?
