The Odor Proof Technology

There are a number of ways that a container locks in smells. While some containers rely on airtight seals, there is no better method as effective as activated carbon lining.

Formline uses the highest quality lining and each bag now includes our patent pending design which provides twice the amount of smell proof lining.

The outside of your smell proof bag needs to durable to resist day to day wear and tear. Typically bag blends use what is called Denier or D for short which is a measurement unit for thickness of fabric.

A Formline Bag will always be made of at least  600D as these are the fabrics typically found in the highest quality backpacks as it is more expensive to produce. Our cases are made with a 1080D blend and also include a lightweight padding to protect your delicate products

Try not to settle for a 300D blend offered by many of the low cost brands which is 1/2 the thickness of 600D and has the look and feel of a giveaway product typically used in promotional giveaway products seen at various events like baseball games, tradeshows, and credit card freebies.
