You can seal Mylar with an iron.
Because I have accumulated Mylar bags, foodsaver bags, and oxygen absorbers, I now use an over-redundant storage process for my hops. I vacuum seal hops in 4-6 oz portions in foodsaver bags with oxygen absorbers, then toss a bunch of those bags in a 1-gallon Mylar bag with another oxygen absorber, then heat seal the Mylar closed with an iron and stainless racking cane or a level.
I think there are two general methods that are sufficient for sealing hops:
1. Vacuum seal in foodsaver bags and store in freezer (using an oxygen absorbers is probably way overkill, but I have so many that I add them anyways).
2. Placing in Mylar bags with an oxygen absorber and heat sealing with an iron (press out as much air as possible before sealing).
Oxygen absorbers are fairly cheap on Amazon. If you have an iron, I would recommend going with number 2 above. When you open the oxygen absorbers, take out only what you need and then toss the rest in a foodsaver bag and vacuum seal for later.
