Humidity Indicator Cards: Saviors Barrier Packaging

Humidity and moisture are invisible yet caustic elements that can cause quick worsening of products in contact. To shun their destructive effects, companies generally rely on packaging experts who can provide them with the required moisture barriers to protect their goods. Although moisture barrier bags or vapor barrier bags one shortcoming and i.e. it is often difficult to moderate the actual levels of humidity within. But there exists a solution for this problem and that is humidity indicator card. Indicating cards are confirm the presence of moisture and hence can make the packaging process a success. These little cards are positioned inside the moisture barrier bag and can be checked time to time at regular intervals during the process of storage. These cards can also be checked at the time of the arrival of shipment and damage can be predicted.  These cards work on an easy color-coded system; they point out dampness levels, and hence show the successful working levels of the desiccants and barrier bags. These cards provide low cost solution for indicating humidity conditions inside a vacuum packaged barrier bag.

Long Term Food Storage with Desiccant Packets - Cargo Dry Paks

Clay desiccant bags are used for removing moisture from enclosed spaces like shipping and storage containers. Clay desiccants work well in temperatures of up to 120°F; above which the clay desiccant may release moisture back into the container. To remove water from liquid or gas, use molecular sieve packets. The capacity for water adsorption of a molecular sieve desiccant is 22% of its weight.

It is important to know that desiccant is not edible.  Desiccant packets come in many different configurations and sizes, usually in packets of 1 gm to 25 gm. They are used in different industries such as pharmaceuticals, food, electronics, textile, stationery, agriculture, leather, etc. the desiccant packets increase the shelf-life of food items by preventing spoilage, fungus, bacteria and keep the food fresh for a long period.

Best Practices for Food Storage with Desiccant Packets

Storing food was never more popular than now. Whether it is a small family of four or a large democratic nation, everyone is storing food for tomorrow. Less time for grocery shopping, the ever increasing prices and the new facilities to store large amounts of eatables are the few reasons why people have begun to take food storage seriously. But, storing food is a hard procedure as food tends to get spoilt due to many unpleasant reasons like fungus, bacteria and humidity. In order to prevent the spoilage of the stored food, many materials are used in packaging. Usually desiccant packets are used to absorb moisture from food products. There are many types of desiccant packets like-silica gel packets, molecular sieve packets and clay packets. A desiccant is a substance that absorbs moisture and removes humidity that destroys products. It protects the food from moisture, humidity, odor, spoilage, bacteria and fungus. It reduces condensation and remains dry even in damp and humid conditions, which are FDA approved, non-toxic, moisture free, DMF free, odorless, food grade and pharma grade packets.

A desiccant is a hygroscopic substance. There are many substances that are hygroscopic, but only few are used in food storage. Silica gel pillow pak can be discovered in wide varieties of materials consisting of composite paper, non-woven packets, polyster packages and others. The best part of silica gel pillow pak is there unique moisture absorbing capability that makes them stand from others. They are available in tyvek packs, cotton bags and a lot others.

Air Drying Desiccant to Absorb Moisture Efficiently!

Desiccants are said as those substances which have the ability to absorb moisture and odor. Having excellent absorption capacity it has the capacity to maintain the originality of the product by preventing any microbial activities. Although moisture is present everywhere, but its presence at unnecessary places can prove to be quite disastrous. Most of the desiccants are available in granular or powdered form. The reason that these desiccants are in this form is that in this way it gets more surface area for absorption. This form allows the desiccant to absorb more moisture content from the atmosphere. However these desiccants cannot be used loosely, so they are used in packets. Now the size of the packets depends on the requirement. You must have seen small packets of moisture absorbing desiccant in leather jackets, plastic containers. While at the same time huge bags of desiccants are also used while transportation that is cargo in a ship.
