A soft package with strengthened hot pressing traces includes a first side wall and a second side wall formed with a folded portion along a folding line and the distal edge of the second side wall is securely adhered to that of the first side wall except of the folding line and the distal edge of the folded portion. A top wall is divided into a first portion and a second portion, wherein a distal edge of the first portion of the top wall is securely adhered to that of the folded portion and a distal edge of the second portion is securely adhered to that of a top portion of the first side wall to form a bag structure. Two strengthened pressing traces are formed on two opposite sides of the top wall. A nozzle is mounted onto the top wall and outwardly extending through the top wall.

A package including: a container; and a plug seal closure operatively engaged with an open end of the container; wherein the container has; a closed end opposing the open end; a container wall extending longitudinally between the closed end and the open end about a longitudinal axis; an end seam extending at least partially across the closed end; and a longitudinal overlapping seam extending from the end seam, a portion of the overlapping seam extending longitudinally along the container wall between the closed end and the open end; wherein the open end is narrower than at least a portion of the container away from the open end of the container; and wherein the closed end and the container wall consist of a one-piece thermoplastic substrate.

The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous-based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat-sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.

A method for performing a task in registration with a discrete seal in at least one material is described herein. The method involves simultaneously forming a discrete seal and a fiducial/eye mark in the at least one material. The method includes providing a detection device; providing a unit operation mechanism; and performing an operation on the material(s) in registration with the discrete seal. The task performed in registration with the discrete seal is based upon the location of the eye mark that was simultaneously formed with the discrete seal. A method of making flexible containers using cutting to form the outer periphery of the packages is described herein. Also described herein are flexible containers and container blanks made by such a method.

A container blank having an article handling feature for handling the container blank as well as the flexible packages made therefrom during manufacture, and method of making flexible packages using such a feature are described herein. Also described herein is an array of flexible packages containing a common article handling feature provided by such a method.

The invention pertains to a method for manufacturing a tampon packaging (24), comprising the steps of: a) wrapping a strip of heat-sealable film (23) around a holding means (1, 18), whereby a first transversal end (27) of said strip overlaps with a second transversal end (28) of said strip; b) heat sealing said first transversal end (27) to said second transversal end (28), thereby forming a tube of film, and c) removing said tube of film from said holding means, thereby obtaining a tampon packaging, characterized in that said heat sealing step (b) is performed at least partly during a combined movement of said holding means (1, 18) and said strip (23). The invention further pertains to related apparatuses, systems of tampon and tampon packaging and methods for manufacturing a packaged tampon.

A mandrel wheel for producing packages is illustrated and described, including: a mandrel wheel shaft having a central axis, a plurality of mandrels attached to the mandrel wheel shaft, an inflow for a coolant and an outflow for the coolant. The mandrels form at least one mandrel group, the mandrels of which are arranged in a plane perpendicular to the central axis of the mandrel wheel shaft. Each mandrel has a hollow space for the coolant, which is connected to an inlet and to an outlet separate from it. At least one distribution element is provided, which connects all inlets of a mandrel group to the inflow and which connects all outlets of the same mandrel group to the outflow, so that the mandrels can be cooled more effectively.

The present disclosure provides a container. In an embodiment, a flexible container (8) is provided and includes a first multilayer film (16) and a second multilayer film (18). Each multilayer film includes a seal layer. The multilayer films are arranged such that seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The films are sealed along a common peripheral edge (20). The flexible container includes a fitment (10) having a base (12). The base (12) includes an ethylene/a-olefin multi-block copolymer. The flexible container includes a fitment seal (22) comprising the base located between the multilayer films. The base is sealed to each multilayer film at a portion of the common peripheral edge (20).

The present disclosure provides a fitment. In an embodiment, a fitment is provided and includes a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material. The fitment is composed of a polymeric composition. The polymeric composition includes (i) from 70 to 90 weight percent of a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.970 g/cc, a melt temperature, Tm, greater than 125 C., and a melt index from 1 g/10 min to 50 g/10 min; and (ii) from 30 to 10 weight percent of an oletin based elastomer having a density from 0.860 g/cc to 0.905 g/cc, a melt index from 0.2 g/10 min to 50 g/10 min, and a Tm less than 125 C.

The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanurate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.
