What Are Smell Proof Bags?

Smell Proof bags are a specially designed bag built to be the most effective solution for locking in the smelly odors of the contents within. They are also excellent choices for preserving the freshness of the products stored within them as well. The best smell proof containers typically come in two styles, a fabric bag with activated carbon lining, or a mylar based solution, capable of heat sealing and long term storage. These sorts of storage options come in many shapes and sizes, and here at we have a wide array of no smell solutions that are suited for all kinds of scenarios.

What is a smell proof bag made of?

Do Smell Proof Bags Work?

Within a scent proof bag, the odor of the contents cannot be detected. It is often misunderstood that a human or dog can smell through and detect the contents within a smell-proof bag.  When people say that they can smell the contents of a specially designed odor proof container, they are typically smelling the contamination on the outside of the device, or there is an improper seal or closure on the said device.

How Do Smell Proof Bags Work?

If you are using a Formline Supply Smell Proof Pouch, then your bag contains a 5 layer system to lock in the scents of your contents. At the heart of these layers is a ultra high quality layer of activated carbon fiber which contains millions of micro pockets. These pockets act like a sponge for any sort of stinky gas produced by your bags contents and traps them before they can be detected outside of the bag.

Are Ziplock Bags Smell Proof?

Are Ziplock Bags Smell Proof?

Ordinary sandwich style bags like ziplock or glad are not designed to be smell proof. These bags are excellent for their intended use which is to temporarily store snacks or food, but instead of having mirco pockets that absorb scents like a Formline smell proof bag, they actually have microscopic pores which can allow the smell to escape over time.

Think of a plastic bag as chain link fence, you can keep larger things within, but you can push things smaller than the chain link outside the fence through the links. In this case, the gas is smaller than the barrier that the bag creates which is why when you give smelly contents enough time, the gas contents from within the bag will begin to seep through the microscopic pores and the smell will permeate about the room.
