Disposable mitts for handling gas pumps, door handles, flush handles on toilets etch. These could be made of plastic or a paper product. Think only need to cover the palm of your hand. Think of a elongated oval shape that would come in a travel pack like tissues do. You could keep them in your car or purse when you have unsanitary or messy situations. .
I would like to create a 5 in one or 10 in one trashbags. Pull one out and have 4-9 more in the can ready to go.

I keep Glad Press 'n Seal Wrap under my cat food dishes. When there are food spills on it I just remove it and replace it with another sheet. It stays put and works great!
We fill glad bags with water and freeze them to keep stuff in our cooler cold without the mess of melted ice.
PLEASE bring back Fresh Protect bags for produce. I swear I could keep lettuce for a month.
In less than 300 words! To protect my new dining room cloths seats from kids(or adult) dirty drippings from gravy or spillage I use press and seal on my cloth chair seats and cover with elegant cloths chair covers to conceal the press and seal. Brilliant and innovative use of your product!
I like to make deviled eggs, however carrying them to functions is a challenge if you don't have a portable container to carry them in. Now that picnic season is upon us, how about an insert for one of your larger containers that can hold eggs. Perhaps one that stacks and give you two levels to carry them in. I have an old Tupperware container, but it is too small to carry many in. Just a suggestion...
We discovered the sandwitch bags are great for storing and sharing rubber baits between friends. you can even put a few in the baf in your pocket, to take on a backwoods trip.
Make a writing surface on the quart & gallon size so you can mark your leftovers and the date, before you put them in the refrid.
