An object of the present disclosure is to prevent wrinkles in a folding line portion of a paper irrespective of the conditions such as the type, the size, and the like of the paper, thereby securing the precision of the position of a folding line when a flap (such as a flap portion) of an envelope is folded back. The folding unit comprises a pair of an upper and a lower guide plates that defines part of the paper conveyance path at the folding position, and the folding plate is configured so that, when turning from the placement position to the overlap position, a lower face of the folding plate overlaps an upper face of the upper guide plate of the pair of the upper and the lower guide plates.

One or more implementations of a thermoplastic bag with a grab zone of deformations including raised rib-like elements positioned in a high-touch area of the bag. For example, the thermoplastic bag includes a hem skirt non-continuously laminated to a sidewall by one or more raised rib-like elements. The grab zone regions of one or more raised-rib-like elements are located in visible and high-touch areas to provide visual and tactile cues of strength and durability. Moreover, the grab zone regions of one or more raised rib-like elements serve to distribute pull and lift forces across a wider area in order to avoid common failures in high-touch areas such as over stretching, punctures, tears, and rips.

Liners for cooking vessels, cooking systems, and methods of making liners for cooking vessels are disclosed. The liner can be a multi-layer liner having a bag-like structure with a closed bottom having a bottom edge, a top opening having first and second top edges, and two sealed sides. The liner can have a first side seal extending along a first end from the top opening toward the bottom edge and a second side seal extending along a second end from the top opening toward the bottom edge. The liner material can include an aluminum foil sheet thermally laminated to a polymer film. The polymer film can include a biaxially-oriented polyethylene terephthalate layer coextruded with an amorphous polyethylene terephthalate sealant layer.

Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

A flexible pouch with a tube spout fitment and removable cap. The flexible pouch has a panel with an aperture and a tube spout fitment that extends through the aperture. The tube spout fitment has a first circumferential ridge with a first diameter and a second circumferential ridge with a second diameter. Also, the second diameter is larger than the first diameter. A dispensing cap is attached to the tube spout fitment. The dispensing cap has a first temporary snap position fitting over the first circumferential ridge of the tube spout fitment and a second permanent snap position fitting over the second circumferential ridge. In this manner, the dispensing cap can be temporarily attached to the pouch during storage, shipping and the like, removed prior to filling the flexible pouch with product, and then permanently attached after the pouch has been filled with product.

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.

A method for producing a bag from a tube including transverse lines of perforations delimiting tabs of the future bag, a rear tab of a first bag being opposite a front tab of the second bag following the first. A first step involves separating the first and second bags; a second step involves separating a piece of waste remaining on one of the bags between the two tabs. The first and second steps are carried out between a first pair of separation cylinders and a second pair of cylinders, the piece of waste being clamped between the cylinders of the first pair during the first step in order to be held on the second bag, then clamped and torn off by the second pair during the second step.

A packaging unit for hygiene articles is formed from a sheet having a folding axis dividing the sheet into first and second regions. One of the inner edge portion and the outer edge portion of the edge zone of the first region is provided with resealable adhesive, thus forming a first adhesive zone. The other of the inner edge portion and the outer edge portion is adhesive-free. The inner edge portion or the outer edge portion of the edge zone of the second region corresponding to the adhesive-carrying edge portion of the first region is adhesive-free, such that when the sheet is folded about the folding axis, the edge portions carrying resealable adhesive in the first region are brought in contact with the adhesive-free edge portions in the second region. A distance between the at least one first folding axis and the first adhesive zone is 1-20 mm.

A packaging unit for hygiene articles is formed from a sheet of material having an inner surface and an outer surface. The inner surface includes an edge zone including an inner edge portion and an outer edge portion. The sheet has at least one folding axis dividing the sheet into a first region and a second region. The inner edge portion and the outer edge portion of the edge zone of the first region is provided with adhesive, and the other of the inner edge portion and the outer edge portion of the edge zone of the first region is adhesive-free. Further, one of the inner edge portion and the outer edge portion of the edge zone of the second region is provided with adhesive, and the other is adhesive-free in a complementary manner to the edge zone of the first region.
