Food Saver vacuum bags allow air evacuation, sealing, and resealing of meat, vegetables, fish, and many other foods. They are compatible with sealing machines FFS006X, FFS017X, and FFS010X. They cannot be used with other Food Saver machines as they require a special socket, nor with the FFS001X machine, which does not have a separate sealing function. Food Saver bags help preserve the freshness of food in the refrigerator, freezer, and cupboards. By removing the air, food freshness is maintained up to 5 times longer, and foods remain fresh in the freezer for months or even years without suffering freezer burn. In this way, cheese can stay fresh in the refrigerator for several months and fresh produce for weeks. Food Saver bags feature a patented design that completely removes air, leaving no air close to the food. They are made from durable, 5-layer material with special grooves that allow efficient and complete air removal. Food Saver bags and rolls are BPA-free, safe for frozen foods, boiling, or microwave use, and prevent freezer burn. Note: For sous vide cooking—the bags withstand temperatures up to 75°C for a maximum duration of 48 hours.
