A 5.0 mil high-barrier bag made from FDA-approved food-grade material for moisture sensitive products. Protects against light, oxygen, and moisture, and features an impressive inner sealing layer designed to seal directly through oils and powders.
Applications: In-process biological media, lateral flow device strip media, ore samples, hops (whole, wet, and pelletized), food products (esp. dehydrated, lyophilized / freeze-dried), in-process nutritional supplement powders, moisture sensitive resins, engineered resins, plastic media, hydroscopic reagents, pharmaceuticals (in-process, excipients, active ingredients), polyester, polycarbonate, emergency supply storage, food testing, vitamins and supplements, cosmetic ingredients, biological samples, veterinary products, electronic components, semiconductors, any product sensitive to moisture or oxygen
This bag works well as a box liner for the following box sizes (and more):
14" x 14" x 16"
14" x 14" x 20"
16" x 12" x 20"
16" x 12" x 22"
18" x 10" x 20"
18" x 10" x 24"
Material: This pouch is made from PAKVF4C, which has a high hot tack strength, wide range of seal ability, and ability to seal through fine powders. It also provides an excellent barrier for oily or greasy products. The outer layer provides oxygen barrier properties and the FDA approved metallocene poly inner layer provides puncture resistance. Ideal for food products with liquid or powder components.

How to Select a High Barrier Bag
A lot of misinformation surrounds “high barrier” materials. A proper film barrier that shields products from light, oxygen and moisture should be completely opaque and multi-layered. Other considerations include the type of material used for the inner layer and the type of seal required.
True Mylar-Foil vs. Metallized Polyester
Many consumers are informed enough to know that they require a “Mylar foil” material but they confuse this with metallized polyester, a completely different material with none of the same barrier properties as a true Mylar foil. Metallized polyester is the material used on Mylar balloons; it is far thinner and shinier than a true foil barrier film. This thin material keeps the balloons lightweight, but is unacceptable as a barrier film. We recommend true Mylar Foil, and a thicker film structure. In fact, even our thinnest film, PAKVF2.5M is 75% thicker than the balloon material.
Material Selection, Product Compatibility & Seal Strength
Material Selection
We offer many film structures to meet the requirements of our customers’ products. These requirements are based on how much oxygen, light and moisture their product can safely be exposed to. Our technical experts take these factors into consideration, as well as how the product will be stored, when they recommend a film structure. The goal is to select a material with enough of a barrier to properly protect the product, while not overspending on unnecessary films.
Industries that require such packaging range from food and pharmaceutical, to biomedical and electronics. Products include in-process ingredients, pharmaceutical products, dehydrated/freeze dried food products, and many other items which may be sensitive to moisture, or subject to oxidation. Our technical background and experience with a breadth of industries makes us uniquely capable of advising our customers on their packaging selection.
Our technical specialists can advise you on packaging products such as aggressive chemicals, flammable compounds, powder products, oily substances, light-sensitive products, in-process ingredients, moisture-sensitive electrical components, acidic food and beauty products, freeze dried foods, raw goods, finished food products.
Product Compatibility
Material selection should be based on the product to be packaged. For example, aggressive chemicals and fine powders both have very specific requirements for the inner layer of the pouch. Chemicals, and even natural ingredients such as lemon, contain agents that can react with different films. In addition to establishing material/product compatibility, the ability to seal through the product must also be confirmed. Certain products leave a residue that presents challenges in heat sealing. Such products include fine powders and oily products. For such items we recommend a film with an advanced inner layer capable of sealing straight through substances/residues.
Seal Strength
It is imperative that the barrier pouch receive a solid seal. We recommend using one of our heat sealers which range from small tabletop units to large free standing units, and even specialty units capable of sealing uncoated Tyvek and other challenging materials. Custom or "contour" seal designs are also an option. Many industries have strict regulations regarding documented seal settings with consistent and measurable time, temperature, and pressure readings for each seal. These “validatable” sealers are produced by IMPAK Corporation and work in conjunction with many of the pouches we produce.
