Is Stasher Sustainable? The Reusable Silicone Bag Reviewed

Stasher turned the humble plastic baggie into a durable, reusable silicone staple. It’s one of the most recognizable zero-waste kitchen products, and mostly earns the reputation, with a couple of asterisks.

✔ Pros
  • Made from premium platinum silicone. BPA-, BPS-, lead-, and phthalate-free
  • Certified B Corp (since 2017)
  • Replaces countless single-use plastic bags; dishwasher-, freezer-, microwave-, and oven-safe
  • Take-back recycling via TerraCycle, plus a repurposing program (worn bags become playground pebbles)
  • Extremely durable, lasts for years of repeated use
✘ Cons
  • Owned by SC Johnson since 2019 (no longer independent)
  • Silicone isn’t biodegradable and is hard to recycle outside the take-back program
  • Premium price versus disposable bags
  • Eco-benefit depends entirely on long-term reuse

What Is Stasher?

Stasher makes reusable, self-sealing bags from platinum silicone, designed to replace single-use plastic bags for food storage, sous-vide, freezing, and more. It’s been a B Corp since 2017 and was acquired by SC Johnson in 2019.

The Sustainability Case

Stasher’s value is durability. A single bag survives the dishwasher, freezer, microwave, and oven and lasts for years, displacing a large number of disposable plastic bags. The company also runs a TerraCycle take-back program and repurposes worn bags into playground pebbles, addressing silicone’s biggest weakness, end-of-life.

Two Things to Weigh

First, Stasher is now owned by SC Johnson, so it’s a corporate-backed brand rather than an independent one. Second, silicone isn’t natural or biodegradable and is hard to recycle through normal channels, so its sustainability rests entirely on you reusing each bag for years (and sending worn ones back rather than landfilling them). Used that way, it’s a genuine win over disposable plastic.

What platinum silicone actually is

Stasher bags are made from platinum-cured silicone, a material derived from sand rather than petroleum. The platinum curing matters: it produces a more stable material with none of the additives that make cheap silicone smell odd or leach at temperature. It is why the same bag can go from freezer to boiling water to a 400°F oven.

Whether silicone counts as an eco-material is a fair question with enough to it that we wrote a separate piece on it: is silicone eco-friendly? The short version: it is durable and inert, but not biodegradable, so its case rests on replacing thousands of single-use bags over its life.

The corners thing, and other quirks

Daily Stasher life has texture the product photos skip. The corners of the bags take some effort to clean by hand (a bottle brush helps, or just use the dishwasher, where they are top-rack safe). They take their time air-drying. And the wide-mouth stand-up styles are far easier to fill and wash than the slim sandwich ones.

None of that is disqualifying; it is the usual tradeoff of durable goods asking slightly more of you than disposables. Start with one stand-up bag rather than a full set, learn the rhythm, then expand. The rest of the category lives in our reusable food storage roundup.

The Verdict: Is Stasher Sustainable?

Stasher is a strong reusable swap for single-use plastic bags, durable platinum-silicone, B Corp certified, with a take-back recycling program, the trade-offs being SC Johnson ownership and that silicone only pays off if you use it for years.

Is silicone sustainable for food storage?

Silicone is a good swap for single-use plastic because it’s durable and reusable for years, but it isn’t biodegradable and is hard to recycle. Its sustainability depends on long-term reuse and using take-back programs at end of life.

Can you recycle Stasher bags?

Yes, through Stasher’s programs, you can send worn or damaged bags back via its TerraCycle partnership, and Stasher repurposes them (for example, into playground pebbles) rather than landfilling them.
