I used to wrap my sandwich in nice tissue paper. However environmenta friendly that is, my sandwich's sauce or vegetable stuff just keeps ripping the tissue apart because it gets wet and soggy, leaving a trail of sauce and wet vegetables in my bag.
I am tired cleaning the mess when that happens so I decided to shift to a plastic sandwich bag which is durable, won't rip or leak and will close the freshness tight inside the bag. I found it in Glad Sandwich Zipper Bag made by Glad Products Company.
It is slightly costly compared to the other sandwich bags I have used before but those cheaper brands leak. Glad Sandwich Zipper Bag is the opposite. It locks in the freshness with its tight zip-seal. The seal is yellow and blue when opened and as you seal them together, it turns to green so you know that your bag is secured. The wide seal is easy to open and close.
The box contains 100 zipper sandwich bags. This bag is not only for sandwich and it can be used for keeping those left-overs, protects household items like recipes, cards, souvenirs, negatives, stamps; good for small trinkets like jewelry, medicine, toiletries during your travel (as this is mandated by the aviation law), loose change, documents, etc.
I am not only keeping my sandwich fresh and secured but my other stuff at home as well.
