disappointed with this product
I bought these bags as a cheaper substitute for the tilia foodsaver bags. I should have spent the money on the foodsaver bags! These bags are much thinner, so they don't protect food as well, and also are not as durable (and therefore reusable as many times) as the foodsaver bags are. They don't have the same built-in air channel design that the foodsaver bags have; rather, they have channel "flaps" trap that air in the bag, especially if they are wrinkled in any way, as they would be if you tried to re-use the bags. Therefore, you can't always vacuum all the air out, especially when the item has liquid- the liquid spills out before all the air is removed, often interfering with the seal. So I actually ended up wasting more money (and time) making new bags trying to get a proper seal. I didn't have this problem with the regular foodsaver bags. I would not recommend this product to anyone.
