Ubbi Silicone Reusable Storage Bag

A sturdy, airtight silicone bag that replaces disposable zip-top sandwich and snack bags: freezer-safe, dishwasher-safe, and built to last for years.

🌿 Ecoxee decision: A solid swap if you are a heavy zip-bag user.

If you burn through disposable sandwich and snack bags, one of these quietly replaces a whole box and keeps going for years. If you already store food in tubs, you may not need it.

The most sustainable option is often the one you already own.

Overview

Disposable zip-top sandwich bags are a daily-waste classic: grab, use once, bin. This sturdy silicone bag replaces them and then some, and it is genuinely airtight, so it keeps snacks fresh and leftovers sealed.

It is tough enough for the freezer and safe in the dishwasher, the microwave and even boiling water for sous-vide. It stands up on its own for easy filling, and the wide opening means it actually washes clean rather than trapping crumbs in a corner.

The honest trade-off is size and effort: it is bulkier than a flat disposable bag, it needs washing and thorough drying between uses, and one bag is not cheap, though it replaces a whole box of disposables over time.

What we like

Genuinely airtight seal
Freezer, dishwasher, microwave and boiling-water safe
Stands up on its own for easy filling
Wide opening washes clean
Replaces a whole box of disposables

Worth knowing

Bulkier than a flat disposable bag
Needs washing and thorough drying
Pricier upfront than a box of bags
One bag is a small capacity for big batches
Silicone is a synthetic material

The honest trade-offs

The nuance most reviews leave out.

Silicone is durable and more stable than plastic, but it is still synthetic and made with fossil-fuel inputs, so the eco case rests on years of reuse.
A reusable bag only wins after it replaces many disposables, so it has to actually get used, not left in a drawer.
It takes a little water and energy to wash and dry between uses.
If you already own containers that do the job, a silicone bag is extra kit you may not need.

Sustainability breakdown

Our honest read on how eco-friendly this really is. Where we cannot verify something, we say so rather than guess.

MaterialsModerate

Food-grade silicone: more stable than plastic, but a synthetic material made with fossil-fuel inputs.

Expected lifespanExcellent

Tough, heat-safe and dishwasher-safe; it should last for many years of use.

End of lifeModerate

Silicone is not curbside-recyclable and does not biodegrade; specialist recycling only.

PackagingInsufficient data

We could not confirm the packaging materials, so we are not going to guess.

Brand transparencyGood

Ubbi states materials and safe-use temperatures clearly.

If you don't buy it

If you already store food in reusable tubs and jars, you may not need a bag at all, so use what you have. Buy this if disposable sandwich or freezer bags are a real habit in your kitchen and you want a lasting replacement.

The Ecoxee verdict

The Ubbi is a genuinely good silicone storage bag: airtight, freezer-safe, tough, and easy to actually clean, so it does not get abandoned. It earns its place by replacing a steady stream of disposable zip-top bags, which makes it a strong swap if you use those a lot, and unnecessary kit if you already store everything in containers. Buy it for the habit you actually have.
