MasterClass Silicone Stretch Lids, 4 Piece Set of 19.5cm Square Food Covers, An Eco Friendly Reusable BPA Alternative to Cling Film

The picture shows the 15cm square silicon cover streched over a 16cm diameter bowl. The silicon cover was streched double before fitting over the bowl. It does work, but you need to be strong enough and use it on smooth surfaced bowl. Our family is happy with the silicon covers, finally we can repace kitchen foil and cling film indefinitely.

Didn't like it don't stretch enough and don't stick.

Like many people, I’m trying to reduce the use of plastics - particularly disposable plastics. Cling-film is one, and it’s quite difficult to find an alternative that works as well and conveniently.I use beeswax wrap, but I don’t like using that on messy things (like peanut butter sandwiches) and I don’t use it on meat. These bowl covers looked like just the thing, as they would be easier to clean than the beeswax wrap.Unfortunately, they aren’t - quite.As others have commented, these silicone sheets are easy enough to clean - but then you have to dry them, and since they stick to each other, the best way to do that is to either hang them up on a little washing line, or drape them over a drying rack, so that the air can get to both sides.In use, it’s the STRETCH that is important. If you just lay the sheet over the top of your container and sort of wiggle it, it won’t stick and you’ll end up with gaps. You have to give it a proper pull (put some effort behind it!) and stretch it properly, then pull down. You also have to go all the way around the container, getting rid of the gaps. This is not a cling-film-esque slap-it-on-and-go operation. You have to devote time and attention to it. However, it is possible to do, although I have to say my confidence in the cover staying put is not necessarily as high as I would like it to be. Because it relies on the stretch, anything that disturbs the edge of the sheet is going to unstick the whole thing.Where I AM going to find this useful is as a lid-liner for my bamboo-lidded glass containers, if I want to put meat or anything messy in them - these will protect the underside of the bamboo lids. These are also freezer-safe, and since I do a lot of freezing, that will help. Although I will be investing in some fasteners to make sure these silicone sheets don’t slip off.

Good replacent for rubber lid which broke.

The media could not be loaded. These are reusable19cm square stretchy silicone lids to replace the need for one use cling film. They have a flat side and a bumpy side and it's the flat side that you need to place face down on to the container that you wish to seal. The bumpy side does not seal as I discovered as there is no instruction regarding this. The silicone stretches over the bowl (or desired vessel) and seals it quite effectively. I sealed up some cooked chicken and tipped it in the video and the bowl remained sealed until I opened it the next day. The steak in the picture was marinating and one tiny bit had lifted up by the time it came to cook it a few hours later. I washed the silicone square once the steak was eaten and dried it. Now this is the thing, you need to be able to ventilate it to get it to dry properly and once dry you can replace it in it's box with the plastic square cover on it to keep it clean. Silicone attracts every pet hair that is loose in my house so I was quite surprised when this dried successfully without acting as a pet hair air filter although I also believe that was beginners luck. I managed to store it away successfully back in it's box and so I suppose that is the routine. I later wanted to seal up some lime juice that I had just squeezed. I made sure to use the square I have already used once and it worked again just fine. This time because I have the juice in a jug and the rim is uneven in height, I used the silicone band to secure it in place and this worked well too.This is an alternative to clingfilm but not an economic one. You can buy an awful lot of cling film for £14.49 so you'd be using these four squares for a long long long long time before you felt any economic benefit - perhaps your kids or grandkids may financially benefit from your decision to buy these. Also quite often you have need of more than 4 bits of silicone/clingfilm so the benefit applies only when used occassionally. That said these do reduce single use plastic and they do seem to work. If your interest is planet saving and let's face it, it's in our interest then this is a step in the right direction.

The media could not be loaded. So we've all used cling film, and many of us have probably tried a few alternatives.I have beeswax wraps, which is okay, not as good as clingflim, but work pretty well.I have silicone "hats", for round items, that stretch and pull over a round bowl, or half a melon, or an open tin.So these seemed to be a good idea - fitting round and square bowls and dishes.Insturctions are simple - the smooth side is the sticky side, so that's what is going to stick to the side of your bowl or dish.Only it doesn't. I tried them with a plastic container, a bowl and a porcelain cup. If stretched and pushed hard, they stick a bit to the porcelain bowl and cups, But no luck with the plastic container (see video)After use, you wash them and then allow the smooth side to dry naturally, where it will regain it's sticky. So you need to have somewhere where you can put this untouched while it dries.Storage isn't simple - folded up, sticky side in, the sticky side sticks to the other sticky side and you have to peel apart for use; but folded inside out (sticky side out) the sticky sides stick to the other lids. (It's a shame they don't stick as well to the items they are supposed to be for!) The best alternative is to have somewhere where you can store them flat, from the biggest to the smallest on top, and hope you don't want to use the medium size ones else you'll have to mess around unsticking them first!It's a no from me, sorry.I hope you found my review helpful.
