In a recent video, a drug dog expert placed marijuana inside odor-proof bags and had a drug dog sniff them. The drug dog did not detect the odor.
The bags are airtight and can be heat sealed. The carbon-lined material absorbs and traps odor molecules, so the smell cannot escape.
Activated Carbon
Smell proof bags feature activated carbon that effectively neutralizes odors. Activated carbon is a form of coal that is treated to increase its surface area and its ability to remove chemicals from liquids and gases.
It works by a process called adsorption, which is when the material attracts molecules to its surface and holds them there. The huge surface area of activated carbon provides countless bonding sites. When odors and vapors pass through it, they stick to the surface, much like iron filings would to a magnet.
This same principle is used in water purification systems to filter out pharmaceutical residue in drinking water. This is the result of prescription and over-the-counter drugs being disposed of improperly, as well as agricultural runoff that can contain synthetic chemicals. Activated carbon is also used in hemoperfusion to remove specific toxins, such as bilirubin and inflammatory cytokines. It is also used in gas-phase applications, such as removing gasoline vapors during fueling of motor vehicles.
Polymer-Based Materials
Polymers are huge molecules that are multiples of smaller chemical units called monomers. They make up many natural substances, including proteins and cellulose. They also are the basis for such man-made materials as concrete, glass, paper, and plastics.
Like long spaghetti chains, polymer chains can be arranged side by side, like the wires of joined paper clips, or they can line up in a crystalline structure, which is stronger and more tightly packed. The latter referred to as a thermosetting polymer, can be molded and then hardened into its final form.
Polymer-based materials with a high strength-to-weight ratio are used in aircraft, automobiles, and spacecraft. They also have a wide range of other uses. Like ceramics and metals, they are categorized as structural materials. The development of new blends and alloys of different polymers is a major area of research. These provide a tremendous flexibility to tailor critical properties of materials to specific applications. For example, a researcher can make a polymer that is incredibly permeable to gases or one that blocks a particular gas from passing through.
Activated Charcoal Felt
Activated charcoal felt is a porous carbon fiber that can be used as an effective odor-eliminating material. Often, it is used in purifying water, reducing odors, and in other applications that require high surface-to-volume ratios. Typically, activated charcoal is made from coconut shells, coal, or wood that has been heated to a high temperature and then filtered.
Many people also use activated charcoal powder as a natural teeth whitener. It is believed that the charcoal will bind to substances in your mouth, making them easier to remove with brushing. However, there are better ways to whiten your teeth than using charcoal.
Activated charcoal also has the ability to trap toxins in your digestive system, which can be helpful for a detox cleanse. This is because it works through a process called adsorption, in which ions or molecules adhere to a surface instead of permeating and being dissolved by the substance. However, you should be sure to drink plenty of water while taking activated charcoal, as it can cause dehydration.
Other Materials
If you’ve ever had to transport your weed in anything other than a smell proof bag, you know how quickly it can permeate any type of plastic or paper. Even a sandwich bag can turn into a stanky danky mess in short order, so anyone who regularly brings weed with them will want to use a smell-proof product like the ones offered by Formline Supply.
These bags and cases are heavily padded with carbon filters that prevent odors from wafting out into the surrounding environment. They also feature a waterproof exterior that keeps moisture, weather, and dirt from leaking into the products within.
One of the most popular questions related to these bags is whether they will prevent sniffer dogs from detecting the contents inside. Technically, sniffer dogs can detect odors through airtight containers, mason jars, and other sealed items. However, a smell-proof bag with a carbon filter is extremely difficult for a dog to detect.
