The metal middle layer blocks light completely 100% (Most "mylar
bags" can see light through)
Our bag with a true metal aluminum inner/middle layer provides the
highest level of protection for long-term storage, which a normal mylar bag could not offer. "Mylar" after all is
metalized film roll, not a type of metal.
Metallic vacuum seal bags are perfect for any type of food stuff;
meat, chicken, fish, produce, and even coffee, tea, and herbs are
kept amazingly fresh when sealed in these bags. We’ve made our new
bags stronger and thicker than ever before,making sure that they
lock out moisture and air. They reduce freezer burn better than any
other bag we’ve tested.
With the true metal middle layer, the bags not only have the
classic look of aluminum but also you can feel the difference of
the quality instantly when hold this bag in hand. Adding value to
your products packed inside.
High quality and in factory-sealed master bag
