Packaging material is provided. The packaging material can include at least one web layer having a surface that includes first and second regions. When corresponding first regions are overlaid with each other and corresponding second regions are overlaid with each other, the overlaid first and second regions can cooperatively surround a cavity. The packaging material further can include a first sealing material disposed in the first region and configured to seal together the corresponding first regions upon application of first conditions to the first sealing material, and a second sealing material disposed in the second region and configured to seal together the corresponding second regions upon application of second conditions to the second sealing material. The second sealing material can be configured such that the first conditions applied to the second sealing material are insufficient to cause the second sealing material to seal.

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.

Multilayer Films have a first skin layer that is prepared from a high density polyethylene and a second skin layer (also referred to as the sealant layer) that is prepared from a linear low density polyethylene (LLDPE) having a density of from 0.90 to 0.92 g/cc and a Dilution Index, Yd, of greater than 0°. Seals can be prepared by placing two pieces of this film against each other such that the sealant layers are in contact with each other, then applying heat to at least one high density skin layer such that heat is transmitted/conducted through the multilayer film in a sufficient amount to melt the sealant layer and form a seal. The use of LLDPE having a Dilution Index of greater than 0° has been found to improve the sealing performance of multilayer films in comparison to multilayer films where the sealant layer is a conventional LLDPE having a Dilution Index of less than 0°.

A method for manufacturing an intermediate material for a soft packaging container according to the present invention includes: a first overlaying step P1 of laying a second raw film sheet 120 over a first raw film sheet 110; a confining portion forming step P2 of forming a filler confining portion 50 for confining a filler 59, the filler confining portion 50 being constituted by a non-joined region between the first raw film sheet 110 and the second raw sheet 12, by joining a portion of the first raw film sheet 110 and a portion of the second sheet 12 to each other; a folding step P4 of folding the first raw film sheet 110 and the second sheet 12 with the first raw film sheet 110 on an outer side, such that the filler confining portion 50 is present in a state where an inner portion thereof is continuous on two sides that are connected via at least one folding position; an accommodating portion forming step P5 of forming an accommodating portion 60 by joining a plurality of portions including at least one of the first raw film sheet 110 and the second sheet 12; and a cutting step P6 of forming an intermediate material A1 for a soft packaging container by cutting at least the first raw film sheet 110. This configuration makes it possible to more readily and reliably manufacture a soft packaging container that has a filler confining portion in more regions.

A method for performing a task in registration with a discrete seal in at least one material is described herein. The method involves simultaneously forming a discrete seal and a fiducial/eye mark in the at least one material. The method includes providing a detection device; providing a unit operation mechanism; and performing an operation on the material(s) in registration with the discrete seal. The task performed in registration with the discrete seal is based upon the location of the eye mark that was simultaneously formed with the discrete seal. A method of making flexible containers using cutting to form the outer periphery of the packages is described herein. Also described herein are flexible containers and container blanks made by such a method.

A fully recyclable environmental protection packaging structure applied to express deliveries, postal services and logistics and made of a planar structure of paper. The packaging structure includes a first surface and a protecting layer overlapped on the surface. The protecting layer includes at least one layer of liner which is a three-dimensional network structure. The packaging structure of the present disclosure can overcome problems that kraft paper bubble bags or envelopes, and paper and plastics can't be separated and recycled to pollute environment in the prior art. At the same time, it can solve technical problems of dust pollution and poor air quality caused by using powdery and granular soft structures used as buffers.

A protective product, such as, e.g., an envelope or pouch, is provided that includes at least one expanded slit paper sheet in an expanded state, and an embossed paper sheet facing the expanded slit paper sheet and fixed to the expanded slit paper sheet along at least a portion of a length in an expansion direction of the expanded slit sheet paper. In the preferred embodiments, the embossed paper sheet has a plurality of embossings that increase the rigidity of the embossed paper sheet, thereby inhibiting deformation of the embossed paper sheet that is fixed to the expanded slit sheet paper.

Methods of making a woven laminated plastic bag having an easy open feature are provided. The easy open feature is generally defined by a weakened portion in the bag, such as formed by cutting, punching, or using a laser to provide a plurality of cuts and/or perforations in the bag. In various aspects the bag can be fabricated from a woven polypropylene and/or polyethylene layer, which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also be sealed to be sealed to provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

Multi-layer bag for bulk material, comprising at least one layer of material comprising paper or paper-like material, wherein two layers of material are formed by pieces of tube (22, 32) inserted telescopically in one another, wherein a first of the pieces of tube (22) inserted telescopically in one another has at one end (27) an overhang (U1) with respect to a second of the pieces of tube (32) inserted telescopically in one another.

A packaging container comprises a laminated sheet where at least a substrate, a barrier layer and a sealant layer are laminated together in this order, and the laminated sheet has a stiffness of 1.01 [mN.Math.m] or less measured by a Taber stiffness tester method in accordance with JIS-P8125.
