ACTIVE POUCHES AND METHODS OF USE
20230166899 · 2023-06-01 ·

Described herein are active pouches for obtaining selected release rates of 1-methylcyclopropene (1-MCP) therefrom. A pouch is a sealed thermoplastic containment or envelope defining an interior volume that is excluded from free exchange with the atmosphere, yet is permeable to both 1-MCP gas and water vapor. The active pouches enclose and contain a clathrate of 1-methylcyclopropene with α-cyclodextrin (1-MCP/CD). The rate of 1-MCP release from an active pouch subjected to a selected set of humidity-mediated disgorgement conditions may be varied by varying the interior volume of the active pouch relative to the amount of 1-MCP/CD contained within the active pouch.

Point of sale envelopes and methods of manufacturing the same

Point of sale envelopes and methods of producing the same are disclosed herein. An example method includes moving a substrate in a direction. The substrate includes a first side opposite a second side. The method includes applying adhesive to the second side of a first portion and a second portion of a first panel of the substrate. The first portion is spaced apart from the second portion. The method includes folding the first panel about a first fold line to couple the first panel to a second panel of the substrate and forming an opening to a pocket in the first panel. The pocket is defined by the second panel and a third portion of the first panel. The third portion is positioned between the first and second portions.

Tri-fold side seamed plastic produce bag and method for making same
09725211 · 2017-08-08 ·

A trifold side seamed film produce bag includes a front wall and a back wall, first and second side edges sealed together and a seamless bag bottom. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. An apparatus for forming the side seamed bags includes an extruder, a tubing flattener, a perforator, a sealer, a corona treater, a printer and a slitter. The treated, printed bags may be stored on rolls for later slitting into two bag streams and folding into thirds.

Method and apparatus for making bag using ultrasonic sealing

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.

Quick adjust print system for pouch filling machines

A print and inspection apparatus for use with a pouch filling and sealing machine. The apparatus has a platform with a vertical height adjustment. A print module and an inspection module are mounted to carriages which are adjustably movable along a horizontal “X” axis and adjustable along a horizontal “Z” axis. A path for the pouches is formed by a guide rail and back rail. The apparatus permits printing of information on a pouch and inspection of the pouch.

RECYCLABLE COMPOSTABLE PAPER BAG
20210060888 · 2021-03-04 · ·

The present invention is directed to a produce bag. More specifically, the present invention is directed to a completely recyclable and compostable grocery-type bag for use with produce and other goods. Ideally, the bag is a calendared single-ply paper with heat-sealed seams that is resistant to destruction from moisture. While produce is contemplated, the bag can be used to contain virtually any product. Preferably, such a bag would have a window or an opening so that produce can be viewed and readily identified.

The present invention is further directed to a process for creating and filling the above bag. Using a standard printing machine, the adhesive is printed onto the paper in register to desired locations on the paper to form the seams of the bag and, optionally border a window area to be cut out of the paper. If the bag is to include a window opening, the window opening is cut out within the area of applied heat-activated adhesive and a screen cover to the window such that the border of the screen cover is applied to overlap the heat-activated adhesive. Optionally, a recyclable and compostable patch can be placed around the window such that the patch covers the edge of the screen and the heat-activated adhesive to form a border for the window. The patch and screen cover to the window, if present, are adhesively sealed to the paper by heat activation. One method of assembling the bag includes forming the adhesive applied paper to create a tube of paper such that the heat-activated adhesive overlaps the paper, heat sealing the paper into a tube, automatedly filling the tube with product, heat sealing the bottom edge and top edge of the product-filled tube to form an enclosed bag with product therein. The forming and filling can be accomplished on already existing automated forming and filling machines manufactured for use with plastic bags and plastic lined paper bags. Thusly creating a sealed, filled paper bag that is a single ply unlined paper with a mesh covering attached to the paper without the need for reinforcement that can withstand the moisture released from the contents and is 100% recyclable and compostable.
