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 silicone oil on the first surface of the nylon film; and a sealant film on the second surface of the nylon film, either directly or via an intermediate adhesive tie layer. An antifog composition is either contained within at least part of the sealant film or is coated on a surface of the sealant film opposite the nylon film. The silicone oil effectively blocks the migration of the antifog composition into the nylon film when the multilayered film is stored in roll form.
Claims60
A multilayered film comprising:
- a) a nylon film having first and second surfaces;
- b) a silicone oil on the first surface of the nylon film;
- and
- c) a sealant film on the second surface of the nylon film, which sealant film comprises at least one polyethylene layer, which at least one polyethylene layer either contains an antifog composition, or has an antifog composition coated on a surface thereof.
A multilayered film comprising:
- a) a nylon film comprising:
- i. a first nylon layer, which first nylon layer has first and second surfaces;
- ii. an ethylene vinyl alcohol layer, the ethylene vinyl alcohol layer having first and second surfaces and which is positioned such that the first surface of the ethylene vinyl alcohol layer is in contact with the first surface of the first nylon layer;
- iii. a second nylon layer, which second nylon layer has first and second surfaces, and which is positioned such that the first surface of the second nylon layer is in contact with the second surface of the ethylene vinyl alcohol layer;
- b) a silicone oil on the second surface of the second nylon film;
- and
- c) a sealant film on the second surface of the first nylon layer, which sealant film comprises at least one polyethylene layer, which at least one polyethylene layer either contains an antifog composition, or has an antifog composition coated on a surface thereof.
A multilayered film comprising:
- a) a nylon film having first and second surfaces which comprises a layer of nylon 6, nylon 66, nylon 6/6,6 or a combination thereof;
- b) a silicone oil on the first surface of the nylon film;
- c) a sealant film on second surface of the nylon film, which sealant film comprises:
- i. a polyethylene layer having first and second surfaces, which polyethylene layer either contains an antifog composition, or has an antifog composition coated on the first surface thereof;
- ii. a first nylon layer on the second surface of the polyethylene layer;
- iii. an optional adhesive tie layer between said polyethylene layer and said first nylon layer, which optional adhesive tie layer attaches the first nylon layer to the polyethylene layer;
- iv. an ethylene vinyl alcohol layer on the first nylon layer;
- and
- v. a second nylon layer on the ethylene vinyl alcohol layer.
A process for forming a multilayered film comprising:
- a) combining a nylon component with a silicone oil component to form a nylon blend;
- b) forming a nylon film having first and second surfaces from the nylon blend, which silicone oil component is positioned at the surface of the nylon film;
- c) coextruding a sealant film onto the second surface of the nylon film, which sealant film comprises at least one polyethylene layer, which at least one polyethylene layer either contains an antifog composition, or has an antifog composition coated on a surface thereof.
A process for forming a multilayered film comprising:
- a) forming a nylon film having first and second surfaces;
- b) coating a silicone oil onto the first surface of the nylon film;
- c) attaching a sealant film onto the second surface of the nylon film, which sealant film comprises at least one polyethylene layer, which at least one polyethylene layer either contains an antifog composition, or has an antifog composition coated on a surface thereof.
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 silicone oil on the first surface of the nylon film;
- and
- c) a sealant film on the second surface of the nylon film, which sealant film comprises at least one polyethylene layer, which at least one polyethylene layer either contains an antifog composition, or has an antifog composition coated on a surface thereof.
A multilayered film comprising:
- a) a nylon 666 film having first and second surfaces;
- b) a silicone oil on the first surface of the nylon film;
- and
- c) a sealant film on second surface of the nylon film, which sealant film comprises:
- i. a polyethylene layer having first and second surfaces, which polyethylene layer either contains an antifog composition, or has an antifog composition coated on the first surface thereof;
- ii. a first nylon 6 layer on the second surface of the polyethylene layer, which first nylon 6 layer has a silicone oil on a surface thereof;
- iii. an adhesive tie layer between said polyethylene layer and said first nylon 6 layer, which adhesive tie layer attaches the first nylon 6 layer to the polyethylene layer;
- iv. an ethylene vinyl alcohol layer on the first nylon 6 layer;
- and
- v. a second nylon 6 layer on the ethylene vinyl alcohol layer, which second nylon 6 layer has a silicone oil on a surface thereof;
- and wherein the nylon 666 film is attached to the second nylon 6 layer via an intermediate adhesive layer.
