The Ultimate Reusable Sandwich Bag

Plastics bags are so 2008. The best reusable sandwich bags let you bring a snack or pack your leftovers, guilt and BPA-free. Not only are Guppy silicone bags a better choice for your health and the environment, but they're just as easy to use as the disposable kind -- plus they're dishwasher safe. Before you get stuck with a reusable silicone bags that don't close (ugh) and aren't made from medical-grade silicone (yikes), here's what you should know about Guppy.

We're on a mission to change the way we consume plastic, one sandwich at a time. Our cult-favorite silicone bags are manufactured from medical-grade materials, made in the United States, and designed by women. Why did we name it Guppy? Because we believe that small changes can make a big difference. We're also on a mission to save fish (not just guppies) from microplastics in our oceans.

Reusable Sandwich Bag That's Great for Fruit

Why We're Obsessed with Reusable Sandwich Bags

When we were growing up, we threw out a plastic bag at lunch every day. At the time, no one really thought about the environmental impact of single-use plastics -- nevermind what happens when plastics break down into microplastics, which are easily ingested by the creatures in our oceans. Not good.

We also firmly believe that using reusable sandwich bags should be easy. Modern life is complicated enough (especially for parents), so we engineered our leak-free design. Made from medical-grade silicone in an ISO certified factory in Maine, The Guppy team is also a firm believer in empowering our communities and avoiding mystery ingredients from faraway factories.

5 Reasons to Choose Guppy Silicone Bags

There are so many reasons to love Guppy. The planet, health, safety, easy... With that in mind, here are a few that we hear time and time again.

Guppy Replaces 1,800 Plastic Bags

The average U.S. school year is 180 days. That's a minimum of 180 plastic bags thrown into landfills that we can't take back. By contrast, Guppy lasts 10 years at least. That means that one reusable silicone bag will replace 1,800+ plastic bags. There are over 50 million kids in school in the United States. Making a small switch for your child can make a big difference.

Meet Leak-Free Sandwich Bags

You can finally save the planet without making a mess. We spent a lot of time designing a leak-proof seal on our reusable sandwich bags. Unlike other models on the market that are prone to leaks and spills, the Guppy keeps lunchboxes across the U.S. clean.


Medical-Grade Silicone Bags, Not Plastic

Ever left a warm plastic water bottle in the car before drinking it? It may have tasted funny because plastic can seep into its contents, especially when exposed to heat. Medical grade silicone is cured at really, really high temperatures, which makes it food-safe and healthcare safe. Guppy is made from the highest quality materials so it's completely BPA and plastic-free.

Dishwasher and Microwave-Safe Reusable Sandwich Bags

We want you to use these again and again, that's why all of our designs are dishwasher-safe. Great for school nights, tired parents and meal preppers alike.
