Abstract
Blister packages are provided which are formed from multilayered films having a lid-stock film which is heat sealed directly to a fluoropolymer film. A polymeric base layer is adhered to a fluoropolymer layer via a first intermediate adhesive tie layer; a support layer is adhered to the fluoropolymer layer via a second intermediate adhesive tie layer; and a metallic foil layer is adhered to the support layer via a third intermediate adhesive tie layer. The blister has a greatly improved moisture barrier over blister packages of the prior art.
Claims58
A multilayered film which comprises:
- a) a polymeric base layer;
- b) a fluoropolymer layer adhered to said polymeric base layer via a first intermediate adhesive tie layer;
- c) a support layer adhered to said fluoropolymer layer via a second intermediate adhesive tie layer;
- and
- d) a metallic foil layer adhered to said support layer via a third intermediate adhesive tie layer.
A multilayered film which comprises:
- a) a polymeric base layer;
- b) a fluoropolymer layer having a first surface adhered to said polymeric base layer;
- and
- c) a metallic foil layer adjacent to a second surface of said fluoropolymer layer.
The multilayered film of claim 22 wherein said fluoropolymer layer is adhered polymeric base layer is adhered to said polymeric base layer via an intermediate adhesive tie layer.
A pharmaceutical package comprising:
- a) a shaped blister container which is formed from a multilayered film comprising:
- i. a polymeric base layer;
- and
- ii. a fluoropolymer layer adhered to the polymeric base layer via a first intermediate adhesive tie layer;
- b) a pharmaceutical product contained within the shaped blister container;
- and
- c) a lid sealed onto a surface of the container, which lid comprises:
- i. a support layer adhered to the fluoropolymer layer via a second intermediate adhesive tie layer;
- and
- ii. a metallic foil layer on the support layer via a third intermediate adhesive tie layer.
A package comprising:
- a) a shaped container which is formed from a multilayered film comprising:
- i. a polymeric base layer;
- and
- ii. a fluoropolymer layer adhered to the polymeric base layer via a first intermediate adhesive tie layer;
- b) a product contained within the shaped container;
- and
- c) a lid sealed onto a surface of the container, which lid comprises:
- i. a support layer adhered to the fluoropolymer layer via a second intermediate adhesive tie layer;
- and
- ii. a metallic foil layer on the support layer via a third intermediate adhesive tie layer.
A pharmaceutical package comprising:
- a) a shaped blister container which is formed from a multilayered film comprising:
- i. a polymeric base layer;
- and
- ii. a fluoropolymer layer having a first surface adhered to said polymeric base layer;
- b) a pharmaceutical product contained within said shaped blister container;
- and
- c) a lid sealed onto a surface of the container, said lid being adjacent to a second surface of said fluoropolymer layer.
A process for forming a pharmaceutical package comprising:
- a) forming a multilayered film for holding a pharmaceutical product by:
- i) forming a polymeric base layer;
- ii) applying a fluoropolymer layer onto said polymeric base layer, which layers are attached via a first intermediate adhesive tie layer;
- and
- iii) molding said film into a shaped blister container, which container has an outer surface, an inner surface, and a cavity;
- b) placing a pharmaceutical product into said cavity;
- and
- c) heat sealing a lid onto the outer surface of said container, which lid comprises:
- i. a support layer adhered to said fluoropolymer layer via a second intermediate adhesive tie layer;
- and
- ii. a metallic foil layer adhered to said support layer.
