OPSAK

100% Odor-Proof & Airtight Protection

Just like our aLOKSAK, the OPSAK (Odor-Proof Storage Bag) is completely water- and airtight — but with one key difference: it also features a 100% odor-proof barrier.

We use the same airtight seal found on our aLOKSAK, but the OPSAK is made with a specialized film that prevents odors from escaping, making it ideal for storing food in bear country or other scent-sensitive environments.

All of our bags, including the OPSAK and aLOKSAK, are FDA approved and safe for food storage.

Thanks to its extreme heat resistance, you can even pour boiling water directly into the OPSAK — though it should not be placed in boiling water or used in a microwave.

Important Note for Users:

To maintain odor-proof integrity, do not contaminate the outside of the OPSAK while loading food.
