| 摘要 |
The present invention relates to sealed pouches, and apparatus and processes for producing the same. The pouch includes contoured first and second lateral edges, with each lateral edge having concave and convex surfaces. The concave surface of the first lateral edge is substantially opposite the convex surface of the second lateral edge and the convex surface of the first lateral edge is substantially opposite the concave surface of the second lateral edge. Accordingly, a distance between the first and second lateral edges is substantially the same for all elevations of the pouch. |
