We test silicone and PEVA reusable freezer bags, picking the most popular bags from the UK's main retailers.
Which? pays for all of the freezer bags we test, just like you would.
If a pack comes with multiple sizes, we test one of each in our seal ease of use and leakage durability tests.
We test the bag seals by opening and closing hundreds of times
We rate how easy the bag seals are to open and close at the beginning and the end of our ease of use test.
We fill the bags with water to their capacity and check for leaks throughout the seal ease of use test.
Disappointingly, not all the bags pass this test.
We place weights from 0.5kg to 1.5kg on each bag to mimic the items the bags could be underneath in your freezer.
Not all bags could keep their seals shut when weighted down.
We put tomato pasta sauce or tomato soup into the bags and store these in a freezer for 21 hours.
We note any freezer burn or damage.
We wash all the bags according to their instructions.
We then rank them from the most stained to least stained, and the most smelly to least smelly.
We label each bag using an appropriate black marker pen to see which is the easiest to label and also to see if the ink stays on for the duration of the 21 hours in the freezer.
Food-grade silicone – a popular choice because of its impressive durability. A silicone freezer bag should outlive your average resealable plastic food bag by years. You can even put silicone freezer bags in the oven and microwave.
PEVA (polyethylene vinyl acetate) – the material is commonly used as a safer substitute for PVC (a mass produced plastic that contains harmful chemicals). You'll often find shower curtains made from this material. Unlike silicone, PEVA is biodegradable which means its lifespan is shorter but it's also easier to recycle.
All the reusable freezer bags we test can be used to store all foods: from meat and fish to fruit and veg.
While a number of the silicone bags do well in our tests, the PEVA bags we test do a lot better on the whole.
Based on our testing alone, we’d recommend PEVA bags.
Plus, it's an added bonus that PEVA bags also tend to be cheaper than silicone bags. Here are some other differences:

Washing your reusable freezer bags correctly is vital to getting the most use out of them.
It’s best to let reusable freezer bags air dry where possible.
Even after following these instructions we still found that most silicone and PEVA bags had some residual staining and still smelled.
