I buy this particular brand of trash bags in the 6 gal size & they are sturdy & works very well for my needs. This time I needed something just a bit bigger & these are working out very good for me. They are sturdy & I believe quite durable. I use them for everyday kitchen trash & threshold up very nicely for me. I dont fool myself in believing that they are puncture proof so I do take care when disposing of pokey, sharp edges items. Otherwise, they work fine for me. I have been buying this brand of trash liners for about a year and a very pleased with this product.
