Snack Bag Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Amazon Basics is the best-performing snack bag brand in July 2026, moving 210,000 units across 3 ASINs for 45.7% of Top 10 volume. Ziploc follows with 100,000 units (21.7%), ahead of Welch's on 60,000 units (13.0%).

With 6 brands splitting the Top 10 and 80.4% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $7.78 to $9.89, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. On the growth side, B07CM84FHL leads positive momentum with ▲ 500.0% MoM growth on 3K units, with B07VLFFV5F close behind at ▲ 166.7% MoM on 8K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
