In an embodiment of the present disclosure, a process for producing a flexible pouch is provided. The process includes placing a capillary precursor element (CPE) between two opposing flexible films. The flexible films define a common peripheral edge. The CPE comprises an array of pins sandwiched between two opposing polymeric strips. The process includes positioning a first side of the CPE at a first side of the common peripheral edge and positioning a second side of the CPE at a second side of the common peripheral edge. The process includes first sealing, at a first seal condition, (i) the opposing polymeric strips to each other to form a matrix, and (ii) sealing the matrix to the two opposing flexible films. The process includes removing the array of pins from the matrix to form an in situ microcapillary strip.

Humidity controlled product methods and packages produced by providing a package material having an interior surface and providing a plurality of humidity control devices in a continuous strip, separating a humidity control device from the strip, adhering the humidity control device to the interior surface of the product package material, and forming the package material into a product package or a product package component with the separated humidity control device adhered to an interior space within the package.

The invention relates to a method for producing paper sacks comprising the following steps: providing a tube section (2) that comprises at least a first paper layer (4) and a second paper layer (6), wherein the first tube section (2) has a first end (8) and an opposite second end (10), and a longitudinal extension which extends from the first end (8) to the second end (10), and the first end (8) is formed by the first paper layer (4) and the second end (10) by the second paper layer (6), forming a first base (12) at the first end (8) and forming a second base (14) at the second end (10).

A method of manufacturing a roll of bags includes: moving a layflat tubing from a feed end toward a produce end of a workstation; sealing the layflat tubing to form sealing lines along a width direction of the layflat tubing; punching the layflat tubing to form punching lines along the width direction; spraying, by a coding machine coupled to the workstation, at least one counting mark on the layflat tubing; cutting by the workstation, the layflat tubing along the width direction to form connected bags; and winding the connected bags into the roll of bags. The connected bags are separated by the punching lines, each bag has one of the sealing lines, and at least one bag has the at least one sprayed counting mark that counts its relative position in the roll of bags.

A system and method of at least partially forming reinforced packages. The method comprises moving a web of material in a downstream direction through a web forming section, at least partially forming at least a bag portion in the web of material during the moving the web of material through the web forming section, forming an attached web by adhering a construct to the bag portion of the web of material, and moving the attached web through a separating station. The moving the attached web can comprise moving the construct with the web of material. The method further can comprise separating the bag portion from a remainder of the web of material to form a bag during the moving the attached web through the separating station, the bag being attached to the construct.

Envelopes include a cover for covering and isolating a closure sealing element on the envelope before the envelope is loaded and sealed. The cover can be formed as part of an adjacent wall of the envelope, and can be separated from the wall by a cut or a line or weakness between the cover and the wall.

Thermoplastic bags with phased deformation patterns are described. In particular, one or more implementations comprise thermoplastic bags with ring rolling, SELFing, or other deformation patterns phased or aligned relative to the sides of the bags. The phased deformation patterns can allow for reducing or eliminating deformation patterns in areas of the thermoplastic bag in which side seals or other seals are formed. Additionally or alternatively, the phased deformation patterns can provide for zones that provide differing properties (e.g., functional or aesthetic). Such zones can vary aligned along a width of the thermoplastic bag and optionally also vary along a height of the thermoplastic bag. The differing zones can provide the thermoplastic bags with phased deformations that provide leak prevention, liquid containment, and other benefits.
