  • Such zippers are commercially available and have from the inside to the outside of the bag strong toothing properties, whereby an initial resistance is given when opening the zipper. This ensures that a high vapor pressure can be achieved in the package.
  • the asymmetric toothing ensures that the zipper is easy to open from the outside.
  • Said glass plate effect can also be influenced by the choice of the mechanical parameters of the film / films.
  • the tendency for a pronounced glass plate effect is namely increased in a soft film, whereas there is a tendency for a less pronounced glass plate effect in a stiffer film.
  • This finding can also be used in the choice of the material of the zipper or the base of the zipper, which is heat-sealed with the sealing layer of the bag.
  • polypropylene is used instead of polyethylene
