Described is an apparatus for packaging tissue products and a relative packaging method.

Contact lens packaging (2) includes two or more individual, sealed blister packs (1) coupled together by a connecting label (5), which includes a uni-axial shear polymer film (6). The connecting label (5) is arranged and oriented such that the tear direction of the polymer film (6) is parallel to a line (A) bisecting adjacent blister packs (1). Methods of binding together two or more blister packs (1) are also described.

An exemplary web of preformed bags includes first and second layers, first and second side, first and second side seals proximate the first and second edges, a plurality of transverse seals extending between the first and second side edges, an opening in the first layer, and a line of separation in the second layer, and first and second cuts in the first and second side seals. The first and second cuts are configured to reduce or eliminate a breaking force necessary to break the first and second side seals when the web is torn along the line of separation.

A packaging material having a core layer and inside and outside laminate portions is provided. The packaging material comprises a first area to form a first package, and a second area to form a second and adjacent package. The first area and the second area have a transversal sealing area between them, and the core layer is provided with at least one weakening portion at the transversal sealing area.

An exemplary apparatus for making packages from a web of interconnected bags includes an indexing mechanism, an opening arrangement, a pair of engagement devices, and a sealing arrangement. The indexing mechanism is configured to move the web of interconnected bags along a path of travel. The opening arrangement is configured to open a bag such that an opening is formed in the bag and a product can be placed into the opening of the bag. The pair of engagement devices are configured to engage the bag and close the opening of the bag. Each engagement device includes a base member, a first link, a second link, a sliding pivot member, and a finger. The first link is pivotably connected to the base member, and the second link is pivotably connected to the first link. The sliding pivot member is configured to allow the second link to slide through the sliding pivot member and pivot in relation to the base member. The finger is connected to the second link. The pair of engagement devices are configured to pull a first side and a second side of the bag in opposite directions. The sealing arrangement is configured to seal the opening of the bag.
