General Mills launched Cheerios with Ziploc PantrySeal exclusively on Walmart.com in the United States on Tuesday, 27 October 2026. The new packaging features a resealable cereal bag designed to make pouring easier and help preserve freshness. The launch follows years of consumer requests for cereal bags that can be closed securely after opening. General Mills said it received hundreds of thousands of requests, comments and reactions annually concerning the issue. The company partnered with Ziploc to develop a closure that fits inside a traditional cereal box.
