almost perfect - comparison between these, frigoverre and pyrex
on May 14, 2012
We have dozens of these Glasslock containers in all sizes purchased both here and from Costco. We use them daily, in our cabinets to store dry goods, in the fridge, and in the freezer. They are most useful in the freezer because the lids are easy to remove even when they're ice-cold.
What makes them less than perfect, for us, is that if you store them with the lids on, when you remove the lids to use them there is a very strong plastic smell in the container. It's so strong that I either wash or wipe out the interior before filling it. What this tells me is that THE PLASTIC LID IS OFF-GASSING into whatever I store in the container.
To counteract this, I put a piece of Martha Stewart Wrap between the container and the lid, with the waxed side facing the food. Of course, the paper makes the container not water-tight; but, I don't need watertight, I need plastic-free food, and this solution works for me.
The instructions indicate that you should not store them with the lids on which, to me, indicates that the manufacturer knows about this off-gassing problem.
We also have dozens of the Bormioli Frigoverre containers which do not have this noxious smell. I still use Martha Wrap on them because absence of smell does not mean absence of off-gassing. The lids on the Frigoverre do not have a silicon seal and are not as secure. But, the lids have a smaller profile and take up less room if your space is limited. When the lids are cold, as in the freezer, they are hard to remove.
Both the Glasslock and Frigoverre containers have straight sides. Our Pyrex containers all have sloped sides. I find the sloped sides hold less food in the same amount of space. Pyrex, though, are available with a glass lid that can be use in the microwave and oven.
I prefer to use the Frigoverre in the cabinets and fridge, and the Glasslock in the freezer, both with Martha Warp under the lid. We use the microwave infrequently so the Pyrex offer no advantages to us.
We do not microwave the containers directly from the fridge. We fill our plates and microwave them. We wash all our dishes by hand and use phosphate-free detergent on the rare occasion when we use the dishwasher.
We have never had a container break or chip and both the containers and the lids are clear and function flawlessly after several years of daily use.
The newer models do stack if you turn the inside one upside down.
PROS: lids are secure and easy to remove even when frozen, sides are straight, there are lots of different shapes and sizes available, including a huge one.
CONS: lids off-gas into food and stick out quite a bit
