Abstract
A multilayered packaging film having good antifog performance that is suitable for use in food packaging. The multilayered film comprises a nylon film having first and second surfaces; a sealant film positioned on the first surface of the nylon film, either directly on the first surface of the nylon film or via an intermediate adhesive; an antifog composition contained within at least part of the sealant film or coated on a surface of the sealant film opposite the nylon film; and a protective film applied onto the second surface of the nylon film.
Claims41
A multilayered film comprising:
- a) a nylon film having first and second surfaces;
- b) a sealant film, positioned on the first surface of the nylon film, either directly on the first surface of the nylon film or via an intermediate adhesive;
- c) an antifog composition contained within at least part of the sealant film or coated on a surface of the sealant film opposite the nylon film;
- and
- d) a protective film applied onto the second surface of the nylon film.
A multilayered film comprising:
- a) a first nylon layer having first and second surfaces;
- b) an ethylene vinyl alcohol layer positioned on the first surface of the nylon layer;
- c) a second nylon layer positioned on a surface of the ethylene vinyl alcohol layer opposite the first nylon layer;
- d) a polyethylene sealant film, positioned on a surface of the second nylon layer which is opposite to the ethylene vinyl alcohol layer;
- e) an antifog composition contained within the sealant film or coated on a surface of the sealant film which is opposite the second nylon layer;
- and
- f) a polyurethane protective film applied on the second surface of the first nylon film.
A process for forming a multilayered film comprising:
- a) positioning a sealant film onto a first surface of a nylon film, wherein the sealant film has an antifog composition which is either incorporated therein or coated on a surface of the sealant film opposite the nylon film;
- and
- b) applying a protective film onto a second surface of the nylon film.
A food package which comprises a container having an open portion and a multilayered film sealing the open portion, which multilayered film comprises:
- a) a nylon film having first and second surfaces;
- b) a sealant film, positioned on the first surface of the nylon film, either directly on the first surface of the nylon film or via an intermediate adhesive;
- c) an antifog composition contained within at least part of the sealant film or coated on a surface of the sealant film opposite the nylon film;
- and
- d) a protective film applied onto the second surface of the nylon film;
- the multilayered film being positioned such that the protective film is away from the open portion of the container.
