Lidding for a child-resistant blister package
View Patent ↗A blister package is provided in which the lidding component includes a tear-resistant nonwoven layer and a barrier layer wherein the controlled delamination of the nonwoven layer increases the puncture resistance, thereby improving the child-resistant properties of the package.
1. A blister package comprising a blister component having an inner surface and an outer surface and a multi-layer lidding component having an inner surface and an outer surface, wherein selected portions of the inner surface of the blister component and inner surface of the lidding component are adhered together to form at least one cavity therebetween, the blister component comprises a first barrier layer, the lidding component comprises a second barrier layer and a backing layer that has a delamination strength less than the peel strength of the adhered inner surfaces of the blister component and lidding component, and the backing layer comprises a fabric material selected from the group consisting of woven material, long metallic fiber material, polymeric fiber material, reinforced polymer material, and warp-knit construction material wherein the fabric material is selected from the group consisting of polyesters, polyamides, polyolefins, and copolymers thereof.
2. A blister package according to claim 1 wherein the fabric material is the woven material.
3. A blister package according to claim 2 wherein the fabric material is the polyamide.
4. A blister package according to claim 2 wherein the fabric material is the polyolefin.
5. A blister package according to claim 1 wherein the fabric material is the long metallic fiber material.
6. A blister package according to claim 1 wherein the fabric material is the polymeric fiber material.
7. A blister package according to claim 1 wherein the fabric material is the reinforced polymer material.
8. A blister package according to claim 1 wherein the fabric material is the warp-knit construction material.
9. A blister package according to claim 1 wherein the fabric material is the polyester.
