Flexible packaging structure with a built-in opening and reclose feature

A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.

The present disclosure relates to strata 2-ply drawstring trash bags implementing a J-flap extended hem to provide increased top-of-bag strength. In one or more embodiments, the J-flap extended hem includes a 2-ply web folded back on itself (e.g., during a hem folding operation to enclose the drawstring within a hem channel). In one or more implementations, a hem seal secures the 2-ply web to an inside surface of the trash bag. At least one ply of the 2 -ply web fold-over extends past the hem seal and is additionally secured to the inside surface of the trash bag via one or more hem skirt seals. For reduced material consumption in certain embodiments, the J-flap extended hem of the present disclosure imparts added strength using only one ply of the 2-ply web fold-over. In some embodiments, at least one ply of the 2-ply web fold-over includes ring-rolled portions to add top-of-bag strength.

CONFORMABLE, RECYCLABLE SHIPPING CONTAINER, MACHINE AND METHOD

The present disclosure is directed to a shipping container with a corrugated medium that lines an interior pocket of the shipping container as well devices and components (e.g., corrugating rollers, corrugating machines, scoring rollers, and scoring machines) that are utilized to manufacture the shipping containers. The corrugated medium has flutes that cushion, support, and protect a product that is shipped within the shipping container. The corrugated medium may include a first portion with first flutes and a second portion with second flutes that are offset relative to the first flutes. The offset first flutes and second flutes results in peaks of the first flutes nesting within valleys of the second flutes, and peaks of the second flutes nesting within valleys of the first flutes.

Device for cooling adhesive applied to a surface of sack bodies

The device for cooling an adhesive applied to a surface of bag bodies includes a transfer conveyor and a cooling conveyor. The transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor, and the cooling conveyor conveys the bag bodies taken over from the transfer conveyor at a cooling conveyor speed. The transfer speed is higher than the cooling conveyor speed, which is why the bag bodies are arranged overlapping each other on the cooling conveyor. Due to this higher packing density, there is achieved a long dwell time of the bag bodies in the cooling conveyor at simultaneously a high flow-rate of bag bodies through the device.

A gusset preheating assembly and a method of using the same. The assembly includes a heating gun assembly mounted on a frame. Spreader rods open up a gap in a bag's gusset and nozzles blow warmed air into the gap. Orthogonally arranged first and second hydraulic members are operatively engaged with heating gun assembly and are activated to move the heating gun assembly vertically or horizontally. Hot air blowing into the gap from the nozzle relaxes the gusset. Pressure is applied to the relaxed gusset, thereby reducing the thickness of the gusset region of the bag. The reduction in thickness makes it possible to increase the number of gusseted bags that are packaged in a container or on a roll.
