Abstract
A method and apparatus for making bags or pouches is disclosed. An ultrasonic sealer may be used to form the seals. Sealing patterns may be used to provide a desired strength profile.
Claims21
A bag machine for creating bags from a web, comprising an input section and a sealing section, where the web moves in a downstream direction from the input section to the sealing section, and wherein the sealing section includes a rotary ultrasonic sealer having a rotating anvil and a rotating horn, disposed to seal at least a portion of the web to itself;
- creating a seal that at least partially forms a bag, wherein the anvil has a sealing pattern that includes micro grooves thereon having a depth of 0.0005 inches or less.

A pouch machine for creating bags from a web, comprising an input section and a sealing section, where the web moves in a downstream direction from the input section to the sealing section, and wherein the sealing section includes an ultrasonic sealer having a rotating anvil and a rotating horn, disposed to seal at least a portion of the web to itself;
- thereby forming pouches, wherein the anvil has a sealing pattern that includes micro grooves thereon having a depth of 0.0005 inches or less.
A method of creating bags from a web, comprising feeding the web to a sealing section in a downstream direction, and sealing the web by applying ultrasonic energy to the web using a sealing pattern that includes micro grooves thereon having a depth of 0.0005 inches or less.
