Abstract
A flexible packaging structure has built-in opening features in a laminate with a first structure adhesively joined to a second structure. A tear area is formed by laser ablation of the laminate along a junction between the first and second portions preferably prior to assembling the laminate into the package. Laser ablation begins at the center of the tear area and progressively moves the laser in a direction radially outward from the center of the tear area. During assembly of the package, a seal is formed between end portions of the first and second portions of the laminate. A score line and a sealant reduction area are also introduced to the package to facilitate opening. The package is opened by pulling the seal near the tear area in a direction along the score line until the contents of the package are accessible.
