(10) 5 Gallon Genuine Mylar Bags (Made in USA) with 2000cc Oxygen Absorbers
* Is it REAL Mylar ???Sadly, many vendors are selling foil-lined bags from China.  Mylar is a brand name for a special film developed by DuPont and like Kleenex and Scotch tape, the name is now being used as a generic term to represent anything similar. However, there is a difference and these come directly from an official distributor for a REAL Mylar manufacturer, who pays no shipping charges and can afford to compete with those selling inexpensive imports.Mylar possesses many desirable properties including gas and moisture resistance, chemical stability, high tensile strength, and when laminated to aluminum foil, Mylar provides a higher puncture resistance than any metallized polyester film. It should be noted that most other flexible packaging companies sell laminated structures with only 0.000285" thick aluminum foil, which provides very little resistance to punctures and tears.
