  • Publication number: 20180162618
    Abstract: A blister sheet includes a container film comprising pockets receiving a content, and a cover film mounted to the container film to close the pockets. The container and the cover film are made of synthetic resins. The cover film is thinner than the container film. One pair of cuts formed for each pocket passes through the container and the cover film and extends to the pocket such that each pocket is placed between the cuts. The container and the cover film are broken from the one pair of cuts toward the pocket. A cutting slit or perforation is formed in the container film to allow for separation of the blister sheet into sheet pieces. The cutting slit or perforation is extended to intersect with the cut and a portion of the cutting slit or perforation that intersects with the cut passes through the container and the cover film.
