摘要:
A method for making a multi-compartment microwavable package having one or more open or closed compartments within the package, and method and apparatus for manufacturing the same, constructed by modification to existing vertical form, fill and seal packaging machines. The invention involves producing a multi-compartment bag having an internal permeable wall between compartments from a single sheet of flexible packaging film. A food product can be placed into the first compartment and steam pack can be placed into the second compartment.

A flexible package having an integrated reclose strip, and method for manufacturing same, constructed by modification to existing vertical form and fill packaging machines. The reclose strip comprises a length of tacky two-sided adhesive tape. The apparatus for applying a reclose strip is incorporated into the mechanism which supplies the continuous sheet of packaging material to the vertical form, fill, and seal machine. The invention involves producing a pillow pouch or vertical stand-up pouch having an integrated reclose strip from a single sheet of packaging film. In one aspect, the reclose strip comprises a release liner on one side after package formation. In one aspect, the reclose strip comprises no release liner and is attached along the longitudinal axis of the sheet of packaging material such that the reclose strip is disposed in a channel or recess in the fill tube. The reclose strip permits the package to be reclosed after initial opening without folding the package.

A stationary tucker bar mechanism attached to a vertical form, fill, and seal packaging machine used to construct a vertical stand-up pouch and a gusseted flat bottom bag. The invention involves producing a vertical stand-up pouch or flat bottom bag from a single sheet of packaging film by forming one or two vertical creases along opposing sides of the packaging film tube prior to forming a transverse seal on the tube. The vertical crease is formed using the stationary tucker bar gusseting mechanism positioned outside the packaging film tube and positioned between two forming plates located inside the packaging film tube. While the tucker bar gusseting mechanism is stationary during operation, it is fully adjustable along multiple axes of orientation.

A vertical stand-up pouch, flat bottom bag, or flexible package, and method for manufacturing same, constructed by modification to existing vertical form and fill packaging machines. The invention involves producing a vertical stand-up pouch or flat bottom bag from a single sheet of packaging film by forming one or two vertical creases along opposing sides of the packaging film tube prior to forming a transverse seal on the tube. The vertical crease is formed using a pivoting tucker mechanism positioned outside the packaging film tube and between two forming plates positioned inside the packaging film tube. A novel method is also disclosed for adjusting the orientation of labeling on the packaging film, which results in the production of innovative packages.

A vertical stand-up pouch or flexible package having an integrated reclose strip, and method for manufacturing same, constructed by modification to existing vertical form and fill packaging machines. The modified machine includes a crease-forming mechanism and an apparatus for applying a reclose strip to the sheet of material. The apparatus for applying a reclose strip is incorporated into the mechanism which supplies the continuous sheet of packaging material to the vertical form, fill, and seal machine. The invention involves producing a vertical stand-up pouch having an integrated reclose strip from a single sheet of packaging film by creating a vertical crease along one edge of a packaging film tube prior to forming a transverse seal on the tube. Said vertical crease is formed using a stationary tucker bar positioned outside the packaging film tube and between two forming plates positioned inside the packaging film tube. The reclose strip is attached along the longitudinal axis of the sheet of packaging material prior to forming the sheet into a tube in the conventional manner. The reclose strip includes a peel strip which is removable to allow the package, when opened, to be folded down and sealed against an adhesive which will be exposed upon the removal of the peel strip. In a preferred embodiment, the reclose strip comprises a length of two-sided adhesive tape.
摘要:
A vertical stand-up pouch, or flexible package having a zipper seal mechanism incorporated therein, and method for manufacturing same, constructed with a quick change module modification to existing vertical form and fill packaging machines. The invention involves producing a vertical stand-up pouch from a single sheet of packaging film by inserting a zipper seal mechanism on a first side of the packaging film tube and creating a vertical crease along the tube prior to forming a transverse seal on the tube. The zipper seal mechanism is attached to the packaging film prior to sealing the sheet of the packaging film along its longitudinal seam forming a tube comprising, in part, a quick change module that easily installs on the base of a forming tube. Likewise, the crease is formed using fixed or stationary modifications to prior art vertical form, fill, and seal machines comprising, in part, a quick change module that easily installs on the base of a forming tube.
摘要:
Slitters cut through a first layer of film immediately prior to lamination of the first layer to a second layer of film to form a strip therebetween. The degree of bonding between the first and second layers is adjusted so that the strip can be removed without harming the rest of the film or destroying any barrier properties. The lamination process can utilize extrusion lamination or adhesive lamination to provide a variety of uses: removable coupons, prize disclosures, stickers, and an adhesive re-close strip.

摘要:
A flexible food package with a wall comprised of thin film layers, at least one of which has a reduced permeability characteristic that reduces absorption by the package wall of oils associated with the food product in the package. The reduced permeability characteristic is achieved by decreasing the amount of amorphousness in the polymers forming the thin film layer. Reducing the amount of oil absorbed by the package wall reduces the amount of swelling, puckering, and disfigurement of the package.
