Sandwich Bags Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Amazon Basics is the best-performing sandwich bags brand in July 2026, moving 210,000 units across 3 ASINs for 61.8% of Top 10 volume. Ziploc follows with 100,000 units (29.4%), ahead of 365 by Whole Foods Market on 20,000 units (5.9%).

With 4 brands splitting the Top 10 and 97.1% 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 $3.79 to $11.19, 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. Specifically, one ASIN forced its way in: B00V3M9DCK booked 10K units at $9.10, with ▲ 42.9% MoM change. On the growth side, B0CWTYV27T leads positive momentum with ▲ 1100.0% MoM growth on 600 units, with B0CFXGVN3T close behind at ▲ 133.3% MoM on 700 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
