Systems for encasing articles such as forage or crop bales in a protective wrap are disclosed. In some embodiments, the system includes a gathering mechanism and sealing device for bunching protective wrap and sealing the ends of the wrap material after one or more articles has been conveyed into the wrap material.

A packaging device includes a resin film, a covering device, and a heating device. The film includes a welding portion containing a hot melt adhesive and is capable of being welded to a portion to be welded. The covering device covers, with the film, at least a part of a packaging object placed on a base formed of corrugated cardboard and at least a part of the base. The heating device heats a contact portion with the base in a state in which the welding portion of the film is in contact with the base. When heat is added by pressing the welding portion against the base, the hot melt adhesive in the welding portion melts and bonds the corrugated cardboard and the film. Polar functional groups introduced into the surface layer of the film are mixed and combined with the functional groups contained in a fiber of the base.

The present invention relates to a device and a method (1) for applying gripping handles (M) on packaging films (P), preferably heat shrinkable, that are being supplied on shrinkwrappers (2) for making bundles (F) of food containers (C). The device (1) comprises: an application head (10) provided with an application roller (11) for applying a plurality of handles (M) supplied in the form of a continuous web (12) and subsequently cut into portions, each handle (M) having adhesive ends (E) for engagement with the corresponding film (P); an abutment mechanism (14) for supporting a plurality of films (P) supplied in the form of a continuous web (5) and subsequently cut into portions, the roller (11) of the head (10) and the abutment mechanism (14) being relatively movable between a non-operating condition, in which they are not engaged, and an operating condition in which the roller (11) of the head (10) is arranged at the abutment mechanism (14), against one of the films (P) being supplied in order to apply on the latter a respective handle (M) being supplied. The roller (11) of the head (10) is motorized and is independently controllable with respect to the feeding of the films (P) being supplied.

A system and method are provided for processing and packaging food product. The system includes at least a transportation system configured to move food product on a conveyor belt, and a collection system configured to receive the food product from the transportation system on a disposable conveyor sheet, and further configured to package the disposable conveyor sheet with the food product thereon on and/or in a dispenser pack.

Disclosed is a method for packaging articles, piece goods, or containers (12) and/or for grouping the articles, piece goods, or containers (12) to form bundles (32) by way of helically wrapping the articles, piece goods, or containers (12) and/or the groupings, which are transported in a conveying direction (18) in an article flow or piece goods flow (14), into multiple layers of an elastic film about a longitudinal axis extending through the article flow or piece goods flow (14), with the elastic film being applied under tension. A film packaging (30) for the articles, piece goods, or containers (12) that moves continuously in conveying direction (18) is formed thereof, which film packaging (30) is provided with perforations (42) in planes perpendicular to the longitudinal axis and/or is severed in planes perpendicular to the longitudinal axis between consecutive articles, piece goods, containers (12), or, as the case may be, between article pairs, piece good pairs, or container pairs, or between groups of a plurality of articles, piece goods, or containers (12) that are being conveyed next to each other, thereby forming bundles (32) that are conveyed one after the other.

The bundles (32) that have been separated from each other are sorted, assembled into layers, palletized, and/or stacked in transport stations and/or in handling stations (34) disposed downstream, with the film packaging (30) being severed at in each case specified and/or variable spacings to preceding separating locations for the purpose of separating bundles (32) of variable sizes or, as the case may be, bundles (32) with a variable number of articles, piece goods, or containers (12) gathered together by means of film.

A device (1) for grouping and combining articles (5) into packages with different package sizes is disclosed. The device comprises a dividing unit (3), by which groups (6a, 6b, 6c) can be formed from moving articles (5). Further, it consists of a cutting station (18) for cutting to length flat thermoplastic packaging material (20) from a supply roll, a workstation (40) for applying the cut-to-length flat thermoplastic packaging material (20) onto the groups (6a, 6b, 6c) of articles, and a shrinking tunnel (50), in order to produce the packages. The dividing unit (3) and the cutting station (18) are operatively connected to one another by a control unit (S), which has information relating to a layer to be produced from the packages.

Provided are a packaging sheet and a packaging container where it is unnecessary to paste a printed label and disappearance or color development due to friction or the like after thermal printing do not occur. The packaging sheet includes a heat seal layer 10 for thermally welding by heating, a heat-sensitive layer 40 including a color developing material that develops a color by heating, and a base material layer 70 that secures the strength and protects the heat-sensitive layer 40. The heat seal layer 10, the heat-sensitive layer 40, and the base material layer 70 are provided in this order from a back surface side in a thickness direction. The packaging sheet is transparent before the heat-sensitive layer 40 develops the color.
