Zip Top Reusable Silicone Bags, 2-Bag Set (Sandwich + Snack)

The Silicone Bag That Stands Up and Zips Shut

Zip Top took the reusable silicone bag and solved its most annoying problem: filling it.

These bags stand up on their own, stay open while you load them, and zip closed with a one-piece top that has no overlapping corners, which also means they actually rinse clean and dry in the dishwasher instead of trapping food in a seam. This is the 2-bag set in gray, a 24-ounce sandwich bag and a 4-ounce snack bag, a sensible starter pair for lunches, snacks, and small leftovers. They are made from 100% platinum silicone in Austin, Texas, which is a genuine point in their favor: domestic manufacturing means more oversight of exactly what is in the material.

For a microplastic-free kitchen the appeal is the same as any quality silicone, with a sharper edge.

Zip Top is 100% platinum food-grade silicone with no plastic, no BPA, no PVC, no lead, and no phthalates, so it does not shed microplastics the way disposable plastic bags do as they wear. They go from freezer to microwave to dishwasher, replace thousands of throwaway bags over their life, and the stand-up design makes them genuinely pleasant to use day to day.

True Shift Score: 8.3 / 10

This is our own assessment, not a lab result or a certification.

It scores high as a 100% platinum-silicone, made-in-USA bag with a smart stand-up, zip-shut, easy-clean design that makes ditching disposable plastic bags genuinely easy. It sits a notch below the inert glass and steel options for one honest material reason, silicone is a stable synthetic polymer rather than an inert natural material, though it does not shed microplastics like plastic, and a touch below the leak-proof pinch-seal bags because the zip seal is very good rather than fully liquid-tight. For easy, plastic-free everyday storage, it is an excellent choice.

The Honest Tradeoffs

Two honest points, one about the seal and one about the material.

1. The zip closure is excellent for everyday use but it is not a fully liquid-tight seal, owners describe it as very good rather than perfect, so a bag squeezed hard or tipped on its side can drip, and it is not the bag for hot soup or coffee on the move. Treat it as superb for dry and semi-solid foods and good for light liquids kept upright. 

2. On the material: like all silicone, this is a stable synthetic polymer rather than an inert material like glass or steel, what earns it a place here is that platinum silicone does not shed microplastics like plastic, not that it is the same as glass. Silicone can also occasionally pick up a stain from something like tomato sauce, though Zip Top resists odors well. 

None of this is a flaw, it is the honest profile of a stand-up silicone bag.

How We Evaluate Food Storage

We look at four things, and none is a lab score:

1. Whether the food-contact surface is inert and won't leach

2. Stain, or hold odors, what the lid is actually made of, since that is where plastic hides in most "glass" storage

3. How well it seals and holds up across the fridge, freezer, microwave, and dishwasher 

4. And how durable it is over years of use

The real shift in food storage is getting your food off plastic and onto more stable materials, glass and steel wherever you can, and high-quality platinum silicone for the flexible jobs they cannot do.
