Different but they work.
Not the same material as the brand name microwaveable zip bags.  As a matter they are not zip bags at all.  These have an adhesive strip to seal.  Not re-useable at all it re-sealable when only using a portion of the steamed product. It does to my surprise work as well as the name brand does.  I just have to get used to the crinkling sound and texture of these bags
