A method of packaging a series of differently shaped objects. The method includes receiving a first object to be packaged and identifying a first length of a stock packaging material suitable for enclosing the first object. The method continues by creating, with a bag making machine, a first bag from the stock packaging material having approximately the first length, which leads to substantially enclosing the first object in the first bag. Then the method continues by receiving a second object to be packaged, the second object having a shape or size different from the first object. A second length of the stock packaging material suitable for enclosing the second object is identified. The method continues by creating, with the bag making machine, a second bag from the stock packaging material having approximately the second length, followed by substantially enclosing the second object in the second bag.

An adjustable pouch machine comprises a vertical sealer module forms transverse seals between two piles of a pouch web to partially define a plurality of pouches. Rollers selectively tension and relax the web on the vertically oriented wheel, allowing them to drop away from heated lands on emergency and cycle stops. A filler wheel has a plurality of adjustable gripper units mounted directly thereon for transporting independent separate pouches cut from the pouch web. An adjustable knife is selectively provided with changeable knife hub sets to handle a variety of pouch sizes where a filler wheel alternately first fills and seals pouches in a train. Gear linkage accommodates variation in distance between hubs of different sets. Various embodiments, apparatus and methods are described.

The present invention relates to a method for making pouches providing a continuous web; folding the web to provide confronting side surfaces joined along a bottom edge; forming a vertical seal between the confronting side surfaces, thereby providing a series of adjacent pockets having opposite side walls with each pocket having an unsealed opening along a top edge; filling the pockets through the unsealed opening with material; sealing the unsealed opening. In the inventive method, which facilitates handling of the continuous web forming the pouches, the web is perforated by a perforation between a leading length piece of the web adapted to form a leading pocket and a trailing length piece of the web adapted to form a trailing pocket, and the distance between a trailing edge of the leading length piece and a leading edge of a trailing length piece is increased for tearing the leading and the trailing lengths pieces apart at the perforation.

Provided are a packaging bag in which the breakage of a handle or irritation to a user's hand due to a load of the packaging bag when the user moves while gripping the handle in a state in which heavy contents such as grain or the like fills the packaging bag can be minimized by forming a sealed handle at the packaging bag, and a method of manufacturing the same.

The packaging bag includes a packaging sheet constituted by a first sheet, and second sheets extending from both sides of the first sheet to be folded in a rear-surface direction of the first sheet so that both ends overlap to be sealed; an upper sealing section sealed so that inner surfaces of the reinforcement film and the packaging sheet adhere to seal an upper section; and a handle section positioned at the upper sealing section and punched to be gripped.

An easy-open and reclosable package includes a pouch including a discrete laminate including a tape including a base strip coated with a pressure sensitive adhesive, and a panel section having a die cut defining a die cut segment, the panel section adhered by the PSA to the base strip; the panel section anchored to a first side panel; the second surface of the base strip anchored to the inner surface of a second side panel; and a product in the pouch. The die cut segment is so arranged with respect to the pressure sensitive adhesive that when the package is opened, the package can be reclosed by adhering the pressure sensitive adhesive to the first side panel.

An exemplary web of preformed bags includes first and second layers, first and second side, first and second side seals proximate the first and second edges, a plurality of transverse seals extending between the first and second side edges, an opening in the first layer, and a line of separation in the second layer, and first and second cuts in the first and second side seals. The first and second cuts are configured to reduce or eliminate a breaking force necessary to break the first and second side seals when the web is torn along the line of separation.
