A crop storage bag (1) made is of a high-strength textile (7) material which is extrusion-coated or laminated with a multilayer film (8) that comprises an insecticidal layer (9) in addition to a hermetic layer (10) which prevents oxygen from entering the bag. This oxygen barrier suffocates the insects inside the bag, and the insecticide kills insects that try to bore through the bag.

A method of manufacturing a bottom gusseted pouch is provided. The method comprises unwinding a pouch webbing in a first flow direction, the pouch webbing defining front and back panels; inserting a gusset webbing between the panels in a second flow direction; attaching the gusset webbing to the panels to form a bottom gusseted end; optionally inserting a closure mechanism between the panels in a third flow direction; attaching the closure mechanism to the panels to form the resealable top end of the pouch; sealing the side edges of the panels to complete the pouch; and optionally cutting the completed pouch from the pouch webbing. At least one of the pouch webbing and the gusset webbing is formed of a supported film.

Automated bag forming systems and methods for their use are disclosed. The automated bag forming systems described herein can be configured to receive a web of bag material and produce individual bags through a sealing and cutting process possessing a high degree of speed, precision, and reproducibility.

A production line configuration apparatus reducing complication of a process performed via a touch panel is provided. A bag making and packaging machine includes an adjustment part, a liquid crystal display, and a control part. The adjustment part performs an operation related to making a bag. The liquid crystal display is a touch-sensitive manipulation part accepting input via a touch manipulation by a user. The control part changes a set value in the adjustment part on the basis of a method for the touch manipulation.

In an apparatus and method for successively making plastic bags, webs of first and second panel materials are superposed and fed longitudinally. A plastic film is slit to form longitudinal slit lines so as to be divided into the web of the first panel material and a plurality of webs of a bottom gusset material before the webs of the first and second panel materials are superposed. Then, the webs of the bottom gusset material are guided and supplied to the webs of the first or second panel material by bottom gusset material guide devices. The bottom gusset material is not supplied from another supply roll, and a pattern discrepancy is not caused.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.
