Mylar^® Bags

Mylar is an industrial trademarked brand name that is often confusing. In its basic form, mylar is a CLEAR material made from polyester resin. IMPAK produces MylarFoil bags used in a wide range of industries which require moisture and oxygen barriers to ensure product integrity. Polyester film, ('mylar') when laminated to aluminum foil provides additional barrier properties and higher puncture resistance than any metallized polyester structure. The ubiquitous "mylar" balloons are actually made from metallized polyester, a very lightweight structure in which the aluminum is deposited onto the surface of the polyester (mylar) film in a thickness measured in angstroms ( 1 angstrom = 1/1000th of a human hair). To compare the properties of MylarFoil, review the specifications for PAKVF4 which has a complete layer ( .00035 ) of aluminum foil with a metallized structure like PAKVF2.5M. An aluminum foil layer actils like a FLEXIBLE can providing the best possible barrier properties. Our PAKVF4PC structure has a .0005 foil layer structure that is 6.0 mils thick. The majority of foil structures use only .00028, a thickness rife with pinhole problems.

We have over 60 films available in stock for custom package production. They range from 2.0 to 10.0 mils in thickness, vary from transparent to opaque and include seven stock colors of aluminum foil. 75% of our work orders are for custom sizes, printing, or materials.

Large Barrier Bags

IMPAK (sorbentsystems.com) produces large barrier bags for applications ranging from microprocessors to bulk food exporters of nuts and green coffee. Custom sizes are always an option. Ask for product specifications.

The photo at right taken at a recent trade show for the Packaging Industry provides a clear visual reference to the range of foil barrier bags produced in inventory with Lot Codes, Q.A. data and Material Specifications readily available. As you can see, standard sizes in our "Large" MylarFoil bags range from 18" x 23" to 54" x 48"; custom sizes produced to specific requirements and often from specific materials such as our ultra high barrier PAKVF4PC represent more than 50% of all production. Large MylarFoil bags are also produced with a ZipSeal™ and inventory is maintained on sizes from 3.4" x 4.0" up to 18.0" x 28" in a foil moisture barrier structure and 26" x 36" in a clear barrier structure.

How Do I Know If I Have The Right Type Of mylar® bag For My Application?

This is an extremely good question. The raw material of bags we recommend for in process ingredient or pharmaceutical product storage were originally designed for exporting packaged dehydrated food products. This bag is 4.5 mils thick and appears to look like aluminum foil, although the top layer is transparent. Long-term food/product storage bags and all high O₂ or H₂O barrier materials are NEVER transparent.

Another type of mylar® foil with which many consumers are familiar is the "mylar® foil balloon" that is often sold for birthdays and other occasions. The industrial name for the mylar® foil balloon material is metallized polyester. This product is mostly cosmetic and has minimal oxygen barrier properties. We produce custom packages from this film - PAKVF2.5M. (Even PAKVF2.5M is actually 75% thicker than the balloon material!)

Any concerned individual should be very wary of an organization trying to promote "transparent" barrier bags or the shiny metallized polyester material as a barrier bag. IMPAK does produce these bags for certain uses. Long-term product storage should never be one of them and as a consumer you have the right to a fraud claim if you have received such information. Please review our product specifications.

One good example to watch for is the US Military MRE products. The packaging material used to produce the MRE's has a very high oxygen barrier. Often they will specify nylon as the outside layer of the material instead of polyester (mylar®) due to its stronger puncture resistance and oxygen barrier properties. Most of all, you will never see a simple mylar® (transparent) structure or shiny mylar® foil (metallized polyester) structure used for an MRE.

It is imperative to have a good seal on any barrier pouch. We recommend using one of our heat sealers. We provide a range of units from small tabletop models to temperature controlled impulse units that can seal uncoated Tyvek and other specialty materials. Custom or "contour" seal designs are an option.

Our vacuum sealers range from a 7 lb. laboratory unit to 80" wide machines tailored to the demands of clean room silicon ingot manufacturing.

However, it is actually possible to use an iron to seal a mylar® bag.
