Abstract
A seal formed of laminated films adhered to a peel strip. The seal includes a target area free of adhesive, and adhesive surrounding the target area. The seal is formed so that the target area is visually distinguished from the surrounding adhesive to facilitate accurate placement of the seal on a medical container by a user. The use of a large adhesive dot pattern enhances the peripheral edge of each adhesive dot to provide a prominent and visual lattice. The prominent and visual lattice distinguishes the adhesive areas of the seal from the non-adhesive areas. The lattice boundary surrounding each adhesive dot is still prominent and visible when a clear and transparent adhesive is applied to selected surfaces of the seal.
