The present disclosure providing a cushion pad includes at least one cushion unit including at least one die-cutting region, a length of the die-cutting region increased when the die-cutting region is unfolded; the die-cutting region is unfolded to form a buffer layer that causes the second surface to expand in a thickness direction of the second surface to play a buffering and protective role thereof; the die-cutting region is unfolded to form a three-dimensional network structure. The present disclosure also provides that a packaging bag with the cushion unit is of a plane structure after production; when the packaging bag is used after being transportation, an object is put into the packaging bag or applying a pushing force to the packaging bag so that the cushion unit is expanded to form the buffer layer, to protect the object inside the packaging bag.

A web of expandable bags, a method for forming a web of expandable bags, and a method of forming an expandable bag containing a product is provided. The web of expandable bags includes a plurality of connected bags. Each bag includes a front ply and a back ply, and each bag is connected to an adjacent bag by a perforated connection. The front and back plies are joined to define a compartment that includes a first side, a second side, a third side that extends between the first side and the second side, and a bag opening that is configured to be closed. The front and back plies include a plurality of slits, and the plurality of slits are arranged in a plurality of spaced apart rows. The plurality of slits allows the compartment to expand in a direction that is perpendicular to the arrangement of the plurality of slits.

An envelope design and processes for manufacturing said envelopes is disclosed herein. The disclosed envelopes have an integrated and removable label portion secured within a panel of the envelope by an adhesive liner. The envelopes may be manufactured by die-cutting the label portions in a paper web, applying the adhesive liner to one side of the paper web covering the die-cut label portions, die-cutting an envelope blank from the paper web, and forming a folded envelope from the blank.

An optical encoder is mounted on the end of the shaft of one roller, which is in turn mounted on framework of the equipment and is driven by a film of material. A computer receives a number of impulses per roller revolution with such impulses transmitted from the optical encoder during the film's passing over the roller. Software of the computer is programed with the exact circumference of the roller before shipment and the computer calculates the amount of film that has passed over the roller and fires solenoid valves to precipitate punching operations based upon the distance traveled by the film. Upon receiving an electrical impulse from the computer control, a solenoid valve releases an intermittent burst of compressed air through a tube to a housing which contains a plastic actuator, a plunger and a spring and which has several holes drilled in it to facilitate movement of said compressed air. The burst of compressed air forces the actuator and plunger downward. After the actuator bottoms out said burst of air is exhausted, the plunger continues to travel downward until the tip of the plunger, containing a steel ball contacts a circular hole in the die which is located in the lower portion of the machine. The force of the ball striking the die cuts the material that is moving between the two components. A spring which rests between the housing and the plunger returns the plunger and actuator to their resting position. The cut out pieces of material travel downward through the hollow center of the die and its holder and are carried by the stream of air created by the suction of the vacuum system through the chambers and ducts of the machine being deposited in a receptacle, preventing the haphazard accumulation of scrap occurring with the prior art.

A bag making apparatus includes an intermittent feed device for feeding sheet panels, an adjustment device for detecting upper and lower thresholds for a length of the sheet panels included in a section from a first drive roller pair to a second drive roller pair, a movement device for moving a processing device and a sensor together as a movable group in the longitudinal direction of the sheet panels. The movement device moves the movable group upstream in response to the adjustment device detecting the upper threshold and moves the movable group downstream in response to the adjustment device detecting the lower threshold. If the movable group is moved, the intermittent feed device determines an intermittent feed distance based on a moving distance of the movable group in addition to output from the sensor and feeds the sheet panels by the determined distance using the first drive roller pair.

A tab system for a folder (10a), and a method of making same is disclosed. The tab is enlarged to carry more information/indicia. The visual indicia space (16a), i.e. the viewable space on the front (32a, 36a) of the folder which allows viewing of the enlarged tab is achieve without violating the overall size restrictions (40a) of the file folder. Instead, the front of the folder adjacent to the tab on the back panel, is cut away (32a,34a) to expose a greater portion of the back panel (14a) and allow an increase in visual indicia space. The remaining portion of the front panel, not adjacent to the tab may also be cut away (34a) to allow other enlarged tab files, with offset tabs, (22d, 21a) to be viewable behind the present file.

摘要:
There are disclosed methods of making drinking pouches constructed from at least two panels of flexible laminate web material, at least a first panel thereof having a structural layer (21), a barrier layer (22) and a sealant layer (23), the sealant layer having a first thickness. An exemplary method comprises the steps of punching a hole (19) through the first panel, extruding molten sealant onto the sealant layer (24), thereby occluding the hole, colling the first panel and joining the panels together to thereby form a drinking pouch.
摘要:
The device makes it possible to produce at least one scored line in at least one plastic outer layer of a film. It comprises a bearing surface for the film and at least one projection for forming the scored line by penetration of the projection into the said plastic layer when the film is in position against the said bearing surface. The projections may be arranged in the form of ribs on one or more coaxial rollers. The projections may form the scored line by ultrasonic plastic flow, the film being compressed between a sonotrode and the rollers. The invention provides methods using these devices. It also provides films having scored lines, and packaging having scored lines.
