In aspects of bi-directional packaging adhesive, a sterile package includes an adhesive patch that adheres to an applied surface. The sterile package includes a non-stick backing that adheres to the adhesive patch, with the non-stick backing being removable for application of the adhesive patch. The sterile package includes packaging that encompasses the adhesive patch and the non-stick backing, and includes a bi-directional adhesive configured to release in a first package opening direction to remove the packaging while maintaining the adherence of the non-stick backing to the adhesive patch, and hold in a second package opening direction to remove the non-stick backing from the adhesive patch along with removing the packaging. A portion of the non-stick backing is attached to an inside of the packaging with the bi-directional adhesive, and the attached portion peels the non-stick backing from the adhesive patch in the second package opening direction to open the packaging.

A tetrahedral-shaped pouch can be opened by tearing from a cut in a first lateral sealing edge and along a longitudinal sealing substantially perpendicular to the first lateral sealing edge to conveniently access non-liquid food contents, such as seeds or nuts. A short longitudinal cut can be made into but not all the way through the first lateral sealing edge, adjacent where the longitudinal sealing is positioned on the first lateral sealing edge. When opening the pouch, by initiating a tear starting at the cut, the packaging material will tear along, but not cross the longitudinal sealing, since the longitudinal sealing is formed from an overlapped and doubly thick section of packaging material. The pouch will therefore open, on at least one side of the tetrahedron, along a predictable tear line following the longitudinal sealing, to form a bowl-shaped receptacle from which the contained food product can be conveniently accessed.

Recyclable pouches formed from rollstock and having a resealable closure that extends into both side edges of the pouch may be produced at high speeds on a single manufacturing line in which the pouches are formed, cut apart, filled, and then sealed if the film forming the pouch comprises a recyclable heat seal layer and a second recyclable layer having a melting temperature of at least 30° C. greater than the heat seal layer.

The present invention relates to a flexible packaging comprising a base layer and a film layer at least partially releasably affixed to the base layer via a pressure sensitive adhesive layer. The pressure sensitive adhesive layer comprises at least one adhesive zone and at least one adhesive-free zone extending continuously in a machine direction. The film layer is scored to form at least one pull tab which is disposed within the at least one adhesive-free zone and the base layer is scored to form at least one cavity which is disposed adjacent the at least one adhesive-free zone.

A system and a method for producing packages (100) provided with a reversible closing system (110) comprising a support (111) fixed to the package and a cap (112) reversibly applicable to the support are presented. The packages are formed by means of a forming tube (210), by forming a tubular structure of flexible material (300) wound around the forming tube. The reversible closing system is applied to the film of flexible material so that the support is fixed inside the packages. The application of the reversible closing system is performed when the film is wound around the forming tube.

The present invention is directed to a process for manufacturing a flexible package suitable for containing a food or beverage ingredient and suitable for use with a food or beverage preparation machine, wherein said process comprises punching a flexible flat blank sheet between a plunger and a cavity that are movable relative to one another. According to the invention, the plunger has a concave end side and convex lateral sides, and the profile curvature of its end side is identical to the profile curvature of each of its lateral sides.

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 olefin-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.

A flexible, sterilizable pouch includes a first gas-impermeable web, a second gas-permeable web, and the third gas-impermeable web. The webs are arranged and sealed to form a cavity portion of the pouch and a header portion of the pouch. The header portion of the pouch is gas-permeable through the second gas-permeable web. The cavity portion of the pouch is configured to hold a medical device for sterilization and is configured to be sealed from the header portion after sterilization, thereby making the cavity portion gas-impermeable. The header is also configured to be removed from the pouch, leaving the cavity portion.
