The foil bags are very tear-resistant and durable (even bone damage to bags when not vacuuming), and unlike foil bags of other manufacturers entirely odorless. The film roll can be variably cut to the required length, welding shut the first page and then as finished Continue editing foil pouches. The bags are also suitable for Sous-vide cooking (low temperature cooking in a vacuum bag), I can only report positive and I will order more. Compared to other manufacturers a lot of goods for money.
