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.

The subject disclosure relates to a plastic envelope suitable for mail automation processing. In an aspect, disclosed is an envelope apparatus having a first side portion, a second side portion, a bottom portion, an opening portion, and a foldable flap portion. In an aspect, the apparatus can have a first side portion comprising a first attached portion between a first transparent sheet and a second transparent sheet. Furthermore, the apparatus can have a second side portion comprising a second attached portion between the first transparent sheet and the second transparent sheet.

A flexible pouch for receiving flowable products that includes a fitment having a spout to allow the flowable products to be discharged from the pouch. The flexible pouch is formed from a top and a bottom web of material. A sealant strip is attached to a top edge of each of the top and bottom webs of material. A fitment having a canoe and spout is positioned such that the canoe is positioned between the first and second sealant strips. The height of the canoe and the width of the first and second sealing strips are the same to minimize the amount of sealant material. The first and second sealant strips are sealed to each other along the entire width of the flexible pouch to entrap the canoe of the fitment between the top and bottom webs.

According to some illustrative embodiments, a protective product is provided that includes: an envelope having a two-layer wall structure, the two-layer wall structure including a) a first outer paper layer, and b) a second inner paper layer, wherein the second inner paper layer includes width-wise positional variations of the side surface of the second inner sheet that cushions items placed within an inner pouch of the envelope, and forms an interior wall of the inner pouch of the envelope and directly contacts the items placed within the inner pouch of the envelope. In some preferred implementations, the width-wise positional variations of the side surface of the second inner paper layer includes pleats, undulations and/or embossments, and, preferably, the pleats, undulations and/or embossments include ridges that extend perpendicular or substantially perpendicular to an outlet of the envelope.

Punched and incised portions can be formed properly, in which it is not necessary to replace an anvil depending on a type of a sheet material. A punching unit 51 comprises: a punching blade 50 for punching a first panel material 11, a second panel material 12, an open tape and a mounting base portion so as to form a punching portion; a incising portion 51 for incising the second panel material 12 and the mounting base portion disposed on the open tape so as to form a incising portion; and an adjusting portion 54 for adjusting a first gap 56 in a punching direction 5Z between edges 50A and 51A of the punching and incising blades 50 and 51.

A process for making a container includes the step of providing at least one of a slider, sticker, textured surface, pattern, or embossed surface along a folded web of thermoplastic material that comprises a plurality of container templates. The process also includes the step of picking up, with a turner, each container template. The turner includes one or more rotator assemblies that include a rotatable shaft and a bag-contacting surface connected to an end of the rotatable shaft. The bag-contacting surface is configured to engage a top exterior side of each container template. Additionally, the process includes the step of reorienting, with the turner, each container template. The rotatable shaft is configured to horizontally translate and rotate each container template.

In order to allow a bag to be easily unsealed by sliding both sides of the bag in a longitudinal direction of a zipper tape irrespective of the rigidity of the zipper tape, a zipper-tape bag according to an aspect of the invention includes: a bag body including at least a pair of facing surfaces; and an elongated zipper tape whose cross sectional profile includes first and second bases each bonded to corresponding one of facing surfaces, and mutually engageable first and second engagement portion respectively protruded from the first and second bases, the zipper tape including an intermediate hinge at at least one point in the longitudinal direction.

In one embodiment, a method for cutting and taping a substrate includes providing a substrate having a first side, a second side opposite the first side, and a perimeter. A first flexible joint is created in the substrate by making a first cut through the first side to the second side making first and second sections. A first length of tape is located along at least a portion the first cut to secure the sections together. A second flexible joint is created in the substrate by making a second cut through the first side to the second side. A second length of tape may connect the additional sections created by the second cut.

An origami envelope and a method of constructing the origami envelope are enclosed. The origami envelope is quadrilateral in shape. The origami envelope comprises a top layer having a front surface and a back surface opposite to the front surface, and a bottom layer having an exterior side and an interior side opposite to the exterior side. The top layer extends to the exterior side of the bottom layer over a portion of the top envelope side to form a closure flap at the exterior side of the bottom layer.
