Systems And Methods Of Bubble Closure Formation For Packaging

Abstract: Methods, systems, and apparatuses of a fluid bubble valve device or element can comprise a plurality of films or webs aligned over the top of each other. For example, two separate webs or film layers of material can be made with two or more different layers of films combined to provide different necessary benefits in manufacturing or forming the valve and sealing to a pouch or package later. The two individual forming webs or film layers are fed into a machine together where channel seals and a bubble pocket are created to form a pathway for a controlled direction for a fluid product to later flow through when the completed pouch or package is used by the consumer. The pocket is formed on both of the two individual forming webs or film layers at the same time. A separate lidding web or layer of material is introduced and sealed over the underside of the bubble pocket to trap air or gas between the lidding layer and the combined individual forming webs or film layers.
