Grease resistant bags are great for packaging items like cookies, brownies, rice crispy treats, pound cakes, and more for short term storage. GPB2W is white in color and measures 4" x 1 1/8" x 4 1/2". It is open on the top and has an expanding side gusset to easily package larger items inside with ease. The 40 GSM paper will keep grease stains from showing on the paper. It can be left open on folded over and closed using a label, sticker or a piece of tape. The bag is food safe and eco friendly. Great for bakeries, restaurants, events, and more.
