These bags hold up to 16 oz of coffee, tea, or specialty food items, constructed with a zip closure and one-way degassing valve that releases naturally emitted carbon dioxide and trapped air, while preventing external air from entering, maximizing taste and flavor. The gusseted bottom allows it to stand on its own and the top features a wide opening to easily load contents. Option to heat seal it closed for freshness, making it tamper proof, then use the tear away strip to open.
