Adhesive reclosable fasteners with visual indicators

摘要

A flexible package and method for manufacturing thereof is provided. The flexible package includes a first layer of adhesive material disposed on an interior surface of the rear panel of the package. The adhesive material of the first layer includes at least one visual indicator formed by at least one area of predetermined shape that is more translucent than adjacent areas of the adhesive material of the first layer. A second layer of adhesive material is disposed on an interior surface of the front panel. The second layer of adhesive material is located opposite the first layer of adhesive material. When the flexible package is not completely sealed, the visual indicator in the adhesive material of the first layer is not visible through the adhesive material of the second layer. When the flexible package is sealed, the visual indicator is visible through the second layer of adhesive material.

主权项

1. A flexible package comprising:
a top end, a bottom end, a first side edge, a second side edge opposite the first side edge, a front panel, and a rear panel joined together to form an interior therebetween configured to retain a product; a first layer of adhesive material disposed on an interior surface of the rear panel, the adhesive material of the first layer including at least one visual indicator formed by at least one area of predetermined shape that is more translucent than adjacent areas of the adhesive material of the first layer; a second layer of adhesive material disposed on an interior surface of the front panel, the second layer of adhesive material being positioned opposite the first layer of adhesive material to permit the flexible package to be sealed when the first layer of adhesive material and the second layer of adhesive material are brought into contact with each other; and when the flexible package is not sealed, the at least one visual indicator in the adhesive material of the first layer is not visible through the adhesive material of the second layer, and when the flexible package is sealed, the at least one visual indicator is visible through the second layer of adhesive material.
