Moisture barrier bags are used to protect moisture sensitive items from damage during transport and storage. All-Spec carries different types of moisture barrier bags that offer EMI, RFI, and static shielding properties in addition to moisture protection. The added EMI, RFI and static protection makes the All-Spec bags ideal for items like surface mount devices (SMD’s), printed circuit boards (PCB’s) and any items that need to be protected from rust or corrosion.
All-Spec carries three different options of moisture barrier bags including the 60 Series, 63 Series, and 64 Series. These bags are constructed differently and thus offer slightly different specifications and features. Made from multiple layers of plastic and aluminum, All-Spec’s moisture barrier bags all offer similar EMI, RFI and static shielding properties but varying levels of puncture resistance and moisture vapor transmission rates (MVTR). The MVTR is measured using the ASTM F-1249 standard which is the amount of water in grams that will move through 100 in2 of the tested material at 100oF in a 24 hour period.
Determining which series of moisture barrier bag to use is based strictly upon your application. Based on the MVTR, thickness and puncture resistance you can choose which bag will work best for you. The 7mil bags, although more puncture resistant, can “crease” easier than the 3.6 mil bags and cause a weak area in the material, leading to potential failure. The 3.6mil bags are generally more flexible but less puncture resistant than the 7mil bags. The 6.1mil bags have the best MVTR which means that less desiccant will be required to eliminate the moisture that does get into the bag. On the other hand, they are less puncture resistant than the 7mil bags and are less flexible than the 3.6 mil bags.

In addition to moisture barrier bags, All-Spec Industries carries a variety of dry storage products to use during the packaging process. It is recommended that you place a humidity indicator card (HIC) and desiccant inside each bag. The desiccant absorbs the moisture that penetrates the bag and the humidity card allows the person who opens the bag to know what amount of moisture has gotten into the bag. In order for the bag to function properly, you can then use a vacuum sealer to remove any existing air. Moisture labels are also available to identify the item as moisture sensitive.
If you have any questions or you need a sample to review for your application please give our customer service a call at 1-800-537-0351 or email us at sales@all-spec.com. We enjoy receiving feedback and if you have any recommendations on what you would like to see on our blog, email us at marvlop@all-spec.com.

Torque is defined as a force which creates a rotation of an object around an axis. The basic formula is the length of the tool multiplied by the force exerted which creates the torque. A good example of torque is using a wrench to tighten bolts. Torque is often measured in inch pounds, inch ounces, foot pounds and Newton meters.
A torque wrench is the the basic tool used to apply torque to a nut, bolt or other type of fastener. There are varying kinds of torque wrenches including the simple beam wrench, click wrench, No-Hub wrench, electronic torque wrench, hydraulic torque wrench and deflecting beam wrench. Torque wrenches are important in order to meet the specified torque for a particular application. This is crucial because over tightening fasteners can damage an item or break the fastener itself. Torque wrenches also ensure that the bolted surfaces have the least amount of wear for the longest life possible.
In addition to torque wrenches, All-Spec also carries torque screwdrivers, insulated torque wrenches, torque power drivers and torque driver handles.
