Don't let the foil run out

What does knurled foil mean?
If you came here, it means your adventure with vacuum packing has already started. It does not matter if you use this method to extend the shelf life of the product, or to fill the refrigerator more economically or for freezing or Sous Vide cooking . In each of these cases, the foil you use for these activities is important. I don't know if you know, but pouches can be smooth and can be knurled. Knurled, that is, they are crimped on one or both sides. The notching can be different, it can be mesh, honeycomb or vertical stripes. You may also come across their other name; embossed pouches , grooved or structured.
Are crimped pouches better for vacuum packing?
Embossing on the pouches makes when closing the bag in the welding machine , the walls of the foil do not touch each other, which leaves channels necessary to suck air and creating a vacuum . Are they better than smooth? If you have bar packer then definitely choose knurled pouches. However, if you are the owner of a chamber packing machine (you put the entire bag with the product there and you close the device with a lid), then choose smooth bags. Foil in the sleeves it is definitely more economical, because it will be perfect for packing products of non-standard sizes.
