To provide a half-cut double-sided tape from a double-sided tape with a release-liner commercially available in the market by means of a simple process without contacting a cutter blade directly to an adhesive layer when making the half cuts in the half-cut process. The invention includes: a processing protection layer formation step of feeding a protect release paper tape having the release surface to the double-sided tape to form a processing protection layer on the double-sided tape with the release liner; a half-cut step of continuously performing half-cut together with the processing protection layer and the double-sided tape on the release liner while leaving only the release liner, and making a number of the double-sided tape pieces of proper length are held on the release liner; a half-cut double-sided tape winding step of winding the half-cut double-sided tape with the release liner while peeling off the processing protection layer. A cut trace has a fully cut region in the width direction of the double-sided tape on the release liner and a non-cut region in the width direction of the protect release paper tape, so that the peeling is facilitated.

Method for perforating a nonlinear line of weakness

A method for providing a nonlinear line of weakness on a web material including providing: a base, a support, a blade, and a driving means. The base may comprise at least one counter component having a length (L.sub.CC) where the counter component comprises a nonlinear shape having a shape width (W). The support may be operatively engaged with the base. The blade may have a length (L.sub.B) and may be disposed on the support so as to either contact or to come in close proximity with the counter component. At least one of the counter component and the blade may have a nonlinear shape. The driving means may be associated with one of the support or the base to reciprocally shift the one of the support or the base with respect to the other of the base or the support for a distance (D) in a shifting direction.

Disclosed is a drug packaging device including a packaging unit and a cutting unit. The packaging unit includes a pair of packaging rollers that are pressed against each other with a drug packaging member disposed therebetween, thereby forming isolation regions in the drug packaging member at regular intervals so that at least one drug accommodation section can be formed between the isolation regions. The cutting unit forms a non-continuous zigzag cut line in which peak-shaped cuts and valley-shaped cuts are alternatively arranged and separated by a plurality of uncut portions. With this structure, it is possible to contribute to improvement in durability of a drug packaging member as well as in cuttability of the drug packaging member.

Dual function portion control container and method of making the same

In an embodiment, a portion control container can have a body and a lid sealed to the body. The lid can have defined therein a spout-type opening. The spout-type opening can be defined by an initiation region having 100% cut-through the lid that transitions to a pattern of reduced strength having less than 100% penetration through the lid. The container can remain sealed until the lid is separate from the container along the seal to provide a dip-type opening or the lid material is torn at the initiation region and pattern of reduced strength to define a spout-type opening for squeeze dispensing of the product from the container.

Aroma penetration heat seal liner and method of sealing a container
11370587 · 2022-06-28 · ·

A non-venting one-piece, partially perforated multilayer induction heat seal liner for a container that allows an aroma or scent from a solid substance within the sealed container to permeate through the liner, while preventing leakage and/or physical contact of the substance by the consumer. The liner includes a partial perforation extending completely through a metal foil layer, and leaving an un-perforated thickness in a paper layer. The partial perforation will allow a prospective customer to sniff the scent or aroma released through the partial perforation, while the liner remains secured to the container, extending shelf life of the substance, and preventing leakage, as well as, contamination, damage and/or reduced volume caused by consumers sampling the substance/product within the container.

There is provided a method of manufacturing sachets. The method involves moving a web of semi-rigid material through a cutting station and simultaneously cutting a discrete cut in the web of semi-rigid material while the web of semi-rigid material continues to move through the cutting station. The method also includes sandwiching the web of semi-rigid material between a first flexible web of material and a second web of flexible material such that the first web of flexible material seals the discrete cuts in the semi-rigid web of material and the second web of flexible material forms a continuous elongate reservoir with the web of semi-rigid material. There is also provided an apparatus for cutting a web of material. The apparatus has a cutting roller and at least one cutting element protruding beyond the exterior surface of the roller, wherein the cutting element has a cutting profile that is at least partly a zigzag shape. Another apparatus for cutting a web of material the apparatus has a first cutting element and a second opposing cutting element, each cutting element having a cutting profile that is at least partly a zigzag shape. Each cutting element is associated with a cam and a rail that are arranged such that the first cutting element follows a path and the second cutting element follows a path that mirrors the path of the first cutting element. The paths have adjacent sections and/or intersecting sections in which the cutting elements come together to discretely cut the web of material while leaving the material intact.
