Mylar bags commonly feature a tear notch and a zipper. The tear notch is a small cut-out at the top of the bag, designed to facilitate easy opening without scissors. This is useful for products that need to be accessed quickly. The zipper is a small plastic closure that runs along the top of the bag and allows the user to easily open and close the bag multiple times while maintaining an airtight and moisture-resistant seal. Either of these options can be added to your mylar bags individually or together.
