Disclosed is a hygienic clamp attachable to conveying chains used in horizontal, form, fill, and seal, packaging machines. The clamp is used for holding the packing film, which is conveyed between various work stations of the machine. The clamp assembly comprises of three components: stanchion, gripper, spring. The clamp eliminates the use of a rivet, previously used for holding the spring, and guiding vertical moment of the gripper during the clamping process. The hygienic clamp replaces the rivet with a mortise and tenon connection. The mortise is located inside the stanchion and the tenent is located inside the gripper. The hygienic clamp also incorporates a ridge (attached to the stanchion) which interacts with the tenon (protruding from the gripper). The interaction between these two parts enables delayed closure of the clamp, independent of the cam's actions, which functions as the primary opening and closing mechanism for the hygienic clamp.

A package for containing liquid-exuding product is formed of a single sheet of film that is folded and sealed at certain locations. The package can include an active member, optionally in the form of absorbent, that is heat staked or otherwise attached to a portion of the sheet of film such that the active member is located on an interior surface of a bottom of the folded and sealed package.

An improved paperboard pouch comprising a multilayer substrate and a method of making the same is provided. The multilayer paperboard pouch comprises an outer surface and an inner surface, wherein one of the surfaces is defined as a food contact surface. In the depicted embodiment, the properties of the polymer layer are chosen to provide adequate mechanical and barrier protection to the paper-based pouch formed on the conventional pouch-forming equipment. A method of manufacturing a multilayer paperboard pouch using conventional bag-making equipment (“CBME”) running at normal production speed for making standard plastic pouches is also provided. First, a paper is extrusion-coated and then the CBME is configured with a feeder for feeding an extrusion-coated paper intermittently for a length along a feeding path; a cutter disposed at a position predetermined for cutting one of the layers of the coated paper and forming a first side gusset, a second side gusset and a bottom gusset portions and for folding each of a first side gusset, a second side gusset and a bottom gusset portions into halves along a center line extending longitudinally thereof; and a sealer for sealing the layers of the polymer with the layers of the bottom gusset portion and the layers of the first and second gusset portions, respectively to form the finished multilayer paperboard pouch ready for sale and distribution to various retailers. It is to be noted that in the depicted embodiment various closure constructions and mechanism can be used for heat sealing the finished pouches.

A method for producing enveloped electroscopic filter material can include feeding, from a main spool, at least one sheet of electroscopic filter material in a first direction, feeding, from a pair of spools, sheets of cover material in the first direction such that each spool feeds a sheet of cover material along a different side of the sheet electroscopic filter material, sealing, via a pair of heat-sealing roller nips, the at least one sheet of electroscopic filter material and the sheets of cover material periodically together to form sealed portions, and cutting, via a cutting mechanism, each sealed portion to produce envelopes of electroscopic filter material. The at least one sheet of electroscopic filter material can extend to the outermost edges of each envelope such that each envelope comprises substantially the same dimensions as the at least one sheet of electroscopic filter material.

A filling machine configured to form, fill, and seal individual packages is provided. The filling machine comprises a disinfection station and a hygienic chamber downstream the disinfection station, which hygienic chamber is configured to reduce the risk for re-contamination of the packages after passing the disinfection station. An inner hygienic zone is formed inside the hygienic chamber, whereby a positive air flow is established from the inner hygienic zone to the hygienic chamber outside the inner hygienic zone.

A system for packaging includes a continuous flow wrap machine, a product reader, and a labeling unit. The product reader is configured to sense each product of the series of products transported on the infeed conveyor of the continuous flow wrap machine and to provide detected information for facilitating access to unique product information associated with each sensed product of the series of products. The labeling unit is adapted to apply visual representation of the unique product information to the tube formed in the continuous flow wrap machine while the tube is moving or to the resulting packaged product while the packaged product is moving.

To provide a method and an apparatus for manufacturing pillow packages provided with a fixing tape with high efficiency while preventing damage to the pillow packages. The method for manufacturing pillow packages includes placing a pillow package 1a among a plurality of pillow packages conveyed by a conveying section 21 on an inclined placement section of the conveying section 21 to incline the pillow package 1a in a predetermined direction to thereby expand the gap between a pillow package 1b placed next to the pillow package 1a on the conveying section 21 and the pillow package 1a and bringing a cutting blade 25 into contact with a string of double-sided tape 16 bonded between the pillow package 1a and the pillow package 1b to cut the double-sided tape 16.
