What Are Smell Proof Bags?

SmellProof bags are a specially designed product 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 storage sacks typically come in two styles, a fabric or cloth bag with activated carbon lining material built in, 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 solutions that are suited for all kinds of scenarios.

Formline products are designed to be a more suited alternative to traditional options such as plastic dime bags, a wooden stash box, a Mason jar, a tin closure or a hemp pipe or vape case. With options in all shapes and sizes, we provide you with one of the must have accessories or gifts for any occasion.

What is a smell proof bag made of?

Does a Formline Bag 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 Does it Work?

If you are using a Formline Supply Odor-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?

Do Ziplock Bags Hold In Smells?

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 skunk like scents that a Formline smellproof bag, plastic bags have microscopic pores which can allow the smell to escape over time. These types of products only reduce smells rather than eliminate them.

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.
