All worth knowing of vacuum bags and vacuum films the word “Vacuum bag” consists of the 2 compound words “vacuum + bag” and right here starting this post and would like to establish initially, specially manufactured a vacuum bag to vacuuming. These high requirements are on a such a vacuum bag: he should be air-permeable, particularly tear-resistant and above all food as well as taste – and odour-free, finally the bag to ensure that the vacuum-sealed products stay fresh as long as possible and protect the contents from ungewolten. A high-quality structure vacuum bags, especially for Aussenvakuumiergerate (bag ahead of the device) consists of layered PE / PA films form which is a particularly strong barrier that deters possible external influences. You may wish to learn more. If so, Black Rock is the place to go. PA share (high-quality slide part) is always as high compared to the PE component, which provides for a tear-resistant and also when welding with a vacuum machine very robust construction. Depending on the manufacturer, the strength of this vacuum bag is between 80 and 170, where the latter are used not for food but for sharp-edged metal parts that could otherwise damage the vacuum bag. More than 4-5 times as strong foil finish as in a normal household foil justifies the higher price, finally it comes to high-quality products which are to be kept fresh for 3 to 5 times longer at full quality preservation and the up to 3 years in the freezer, no freezer burn or air pockets.

What a vacuum bag live looks like in use with a vacuum machine lava shows the following video: compared to a normal household foil a vacuum bag is so resilient and running especially with stronger foil, a foil is not suitable for vacuuming and would only cause that a welded bag again inevitably draws air.
