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.

How Do I Know If I Have The Right Type Of mylarŪ 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 mylarŪ foil with which many consumers are familiar is the "mylarŪ foil balloon" that is often sold for birthdays and other occasions. The industrial name for the mylarŪ 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 (mylarŪ) due to its stronger puncture resistance and oxygen barrier properties. Most of all, you will never see a simple mylarŪ (transparent) structure or shiny mylarŪ 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 mylarŪ bag.
