A heat sealing machine and method form blister packages. A backing material web extends between a nesting tray assembly and a seal and cut tooling assembly and a blister tray is resident within a blister nest of the nesting tray assembly. The backing material web is clamped between a clamping gasket support shoulder of the nesting tray assembly and a clamping shoulder of the seal and cut tooling assembly, and between a sealing gasket support shoulder of the nesting tray assembly and a heat seal shoulder of a heater assembly. A knife of the seal and cut tooling assembly extends between the clamping gasket support shoulder and the sealing gasket support shoulder to cut a backing sheet from the backing material web that is heat sealed to an attachment surface of the blister tray to form the blister package.

A packaging container for holding contents such as fresh food. The container comprises a tray having a flange, a pre-formed scaling ring and a flexible film for sealing in the contents of the tray. The sealing ring is made from fiber, filament or tape (“FFT”) that is shaped into a shape that matches the shape of the tray flange. The sealing ring is adhered to the tray flange by heat welding or other means and the flexible film is adhered to the sealing ring.

Embodiments herein include a system for joining components. The system can include a rotating base platform, a plurality of receptacles mounted to the base platform, and a rotating sonotrode platform. A plurality of sonotrodes are mounted to the sonotrode platform. Each sonotrode can correspond to a receptacle. Each sonotrode can move in a reciprocating motion between a release position distant from a corresponding receptacle and a compressing position proximal to the corresponding receptacle. The compressing position occurs at a first angular position of the sonotrode platform. Each sonotrode is energized at the compressing position.

A method for producing a package which has a formed part with a product cavity, and a lidding film covering the product cavity. According to the method, a seam is defined, the seam is divided into sections, a pull-off force for pulling the lidding film from the formed part at least for a first section is determined, and the lidding film is sealed to the formed part. The sealing temperature for the first section is selected based on the pull-off force.

Introduced here are carrier tape assemblies that can improve efficiency and reduce costs when utilized in the handling, transport, or storage of semiconductor components. A carrier tape assembly can include an adhesive film affixed to an elongated and/or extruded carrier tape. For example, the adhesive film may be integrally laminated onto the top surface of the elongate carrier tape as a single continuous (i.e., unbroken) sheet. The adhesive film may substantially conform to the top surface of the elongate carrier tape, including any punched cavities for holding semiconductor components. Proper securement of the semiconductor components to the carrier tape assembly depends on the adhesive property of the constituent material(s) of the adhesive film.

A package that is suitable for packaging an article for collecting or administering a pharmaceutical active substance is disclosed. The package includes a first packaging component that includes a product-contacting sealant layer that includes a first ethylene vinyl alcohol copolymer. The package includes a second packaging component that includes a product-contacting sealant layer that includes a second ethylene vinyl alcohol copolymer. The ethylene content of the second ethylene vinyl alcohol copolymer is equal to or less than about 38 percent and the ethylene content of the first ethylene vinyl alcohol copolymer is greater than the ethylene content of the second ethylene vinyl alcohol copolymer.

Described herein are polymeric composites that can include a kaolin filler dispersed within a thermoplastic polymer matrix. The kaolin filler can exhibit an aspect ratio of from 20 to 50, as measured by laser scattering, a mean particle size of from 0.75 microns to 2 microns e.s.d., as measured by Sedigraph, or a combination thereof. In some embodiments, the kaolin filler exhibits a ratio of aspect ratio to mean particle size ranges from 4 to 5, as measured by laser scattering. In some embodiments, less than 30% by weight of the kaolin filler exhibits a particle size of less than 0.5 microns e.s.d., as measured by Sedigraph. The composites can exhibit improved mechanical properties such as flexural strength, tensile strength, and heat deflection temperature. The composites can be used to form articles, for example, by thermoforming.

A container forming apparatus includes a plurality of forming members that have outer forming surfaces, which are shaped to form pockets in a sheet of material. A plurality of actuators are in mechanical connection with the forming members. The actuators are able to extend and retract the forming members. A controller is in electrical communication with the plurality of actuators. The controller is able to simultaneously extend any one or any combination of the forming members to create a plurality of pockets in a determined pattern in the sheet of material to produce a customized blister pack.

A multi-layer film structure for use in forming blister packaging. The multi-layer structure includes a first polymeric layer having a first surface and a second surface, the first polymeric layer comprising a metalized polyethylene teraphthalate, a second polymeric layer having a first surface and a second surface, the first surface of the second polymeric layer disposed adjacent the second surface of the first polymeric layer, the second polymeric layer comprising a cyclic olefin or a homopolymer of chlorotrifluoroethylene, and a third polymeric layer having a first surface and a second surface, the first surface of the third polymeric layer disposed adjacent the second surface of the second polymeric layer, the third polymeric layer comprising polypropylene or polyvinyl chloride. A method of making a multi-layer film structure and a packaging structure are also provided.

A rotary sealing apparatus for a blister packaging machine is disclosed. The rotary sealing apparatus includes a guide plate adapted to support a movement of a base foil having a plurality of blister pockets. The rotary sealing apparatus includes a counter sealing roller adapted to rotate to advance the base foil in a direction away from the guide plate and a sealing roller adapted to feed a seal foil between the counter sealing roller and the sealing roller. The counter sealing roller includes a plurality of cavities adapted to accommodate the plurality of blister pockets. The rotary sealing apparatus includes a cavity alignment unit disposed on the guide plate and adapted to align the plurality of blister pockets with the plurality of cavities. The cavity alignment unit is adapted to clamp the base foil on the guide plate to stretch the base foil to align the plurality of blister pockets with the plurality of cavities.
