Weck Keep-fresh Lids

$1.32 $2 In stock

Food expands when frozen, so these lids will expand to prevent pressure building inside Weck glass jars. Made from BPA-free plastic, these lids provide a strong seal and will not react with foods or absorb odors. Recommended particularly for refrigerator and freezer storage.

Finally, no more worrying about cracked jars or messy leaks in the freezer. The flexible plastic lid actually does expand with the food, and the seal stays strong even after a few weeks.

I was worried about glass jars cracking in the freezer, but these lids flex just enough to handle the pressure—no more mess. The BPA-free plastic feels sturdy and hasn’t picked up any odors from tomato sauce or curry. Exactly what I needed for my canning routine.

These snap on in seconds and give such peace of mind when I’m freezing soup in glass jars. The BPA-free plastic is sturdy but still gives that little bit of give when contents expand, so nothing cracks or explodes.
