Humidity and moisture are invisible yet destructive elements that can contribute to the rapid deterioration of many products. To avoid their damaging effects, companies usually turn to packaging experts who can supply them with the necessary moisture barriers to protect their goods. At Protective Packaging Corporation, we have spent the last 25 years providing major companies, the American government and military with the latest and most effective packaging products on the market.

Although moisture barrier bags or vapor barrier bags have very specific quality ratings, it is often difficult to judge the actual levels of humidity within. At Protective Packaging Corporation we only use top-of-the-line materials. Our moisture barrier bags have an MVTR rating of 0.02. This means that only 0.02 grams of moisture can ever seep in within a 24-hour period in 95 percent humidity. Coupled with the use of desiccants, that number falls even lower.

With that being said, how does one know if a desiccant is working? How can one tell if it needs replacing? One simple way is the use of a humidity indicator card. Humidity indicators confirm that your protective packaging has done its job. These small humidity indicator cards are placed within the moisture barrier bag and can either be checked upon arrival of a shipment or at regular intervals during storage. By using a simple color-coded system, these cards indicate humidity levels, showing how well the barrier bag and desiccants are working.

At Protective Packaging Corporation, we focus on providing our customers with every available option to keep their products safe. From moisture barrier bags to desiccants and humidity indicator cards, we offer a wide range of high quality products. No matter your packaging needs, our experts are dedicated to finding the optimum solution.
