This type of bag is surprising in it's strength. It is certainly not puncture proof but it is more so than some I have had. It is good for leaves and shredded paper. Sharp object puncture it fairly easily. It sounds like it should fit the big waste disposal service can but it doesn't. It works great in a standard 30 gallon can with overlap. Pretty good value for the money when buying the box of 100 at $29.95 at Amazon.
If reviewing a product, it may have been received free of charge. That will NEVER have a bearing on my recommendations.
