A heat seal between a plastic bag and a plastic sheet is used to provide a more secure and reliable seal to define a modified atmosphere for a pallet of perishables. The heat seal reduces atmosphere failures and aids in providing a more consistent atmosphere in the pallet bag system thus reducing the number of pallets that have an out of specification atmosphere. The heat seal may be created with a heating sealing apparatuses that is part of a system used to load and seal a load of containers of perishables onto a pallet. The heat sealing apparatus uses a plurality of heated bar assemblies to form seal portions on sides of the pallet in order to form a seal around the entire perimeter of the pallet.

Various embodiments of the present disclosure provide a stretch-hood machine configured to optimize reefing device lateral movement and unwinding speed during film stretching to minimize reefing device travel distance and wear on the actuators that move the reefing devices and to reduce the possibility of damaging the film during stretching.

A packaging system for packing a product includes at least one of a bagging unit, a pallet loading device, and a pallet securing device. The packaging system also includes a device to determine information regarding future events associated with the packing of the product, and to render the information available.

A method for packaging a pack commodity comprises: providing a support element having an upper side, a lower side and side surfaces; placing a first packaging material sheet on the upper side; arranging the pack commodity on the first packaging material sheet such that a portion of the first packaging material sheet lies between the support element and the pack commodity and that with parts of the first packaging material sheet protruding beyond the pack commodity; placing a second packaging material sheet on an upper side of the pack commodity such that parts of the second packaging material sheet protrude beyond the pack commodity; folding the protruding parts so that they overlap along an overlapping portion on the side surfaces of the support element; applying a peripheral angular contact-pressure device laterally to the overlapping portion and to the upper side of the second packaging material sheet; and bracing the angular contact-pressure device by applying tension straps to generate a contact pressure in the overlapping portion.

The present invention relates to a film wrapping machine for a product packing device using a stretch film, including a frame having vertical bars extending upward and spaced apart from each other, a film clamping unit including a pair of suction pads which are moved in a direction of being spaced apart from each other in a state of adsorbing the stretch film so that a front end portion of the stretch film supplied from a film supply device is opened, and a plurality of clamps configured to grip the front end portion of the stretch film opened by the suction pads, receive the stretch film whose upper end is cut and bonded by the film supply device in a wrinkled state, and process the stretch film to be covered on a product in a process of lowering the vertical bars, and a controller which controls operation of the film clamping unit and the film supply device.

Various embodiments of the present disclosure provide systems including stretch-hood machines configured to vertically and horizontally apply tubular stretch film to loads of goods and to methods for wrapping loads of goods with multiple segments of tubular stretch film.

A corner post application system comprises a conveyor subsystem and an enveloping machine adapted to envelope the plurality of units with a material. The system further includes a swing arm, an applicator arm coupled to the swing arm and adapted to move linearly, a corner post gripper coupled to the applicator arm, and a controller. The controller rotates the swing arm about a vertical axis until a corner post held by the corner post gripper is aligned with adjacent sides that define a corner of the load. The controller thereafter stops rotation of the swing arm and moves the applicator arm linearly toward the corner of the load until the corner post held by the corner post gripper contacts the adjacent sides of the load. A sensor may be included for detecting a corner of the load, with the controller aligning the corner post based on detection by the sensor.

A foldably constructed pallet includes a top member forming a top surface and includes a top perimeter edge and a plurality of upper edge supports extending from the top perimeter edge and perpendicular to the top surface. The foldably constructed pallet further includes a bottom member forming a bottom surface. The bottom member includes a bottom perimeter edge and a plurality of lower edge supports extending from the bottom perimeter edge and perpendicular to the bottom surface. The foldably constructed pallet further includes a plurality of structural inserts received between the top and bottom members and positioned adjacent to the plurality of upper edge supports and the plurality of lower edge supports.

A process for wrapping a stack of goods in film, wherein a portion of film is drawn from a film supply, cut, opened by a film opening means and pulled over the stack of goods by a travelling pulling means, wherein, after being drawn off and cut, the portion of film is transported lengthwise by a film transport means to the film opening means, characterized in that the portion of film is transported from the cutting unit as far as the film opening means by being gripped by frictional engagement between at least two conveyor members pressed together and circulating endlessly in a transport direction.

The present invention concerns a device and method for reefing a portion of tubular film, the reefing device having at least one reefing finger and at least one drive unit. The drive unit has advancing means, which, for reefing the portion of tubular film, is brought into operative connection with the reefing finger at least at the height of a point of engagement, while enclosing the portion of tubular film, and moves the portion of tubular film in relation to the reefing finger. The device according to the invention and the method according to the invention are distinguished in particular in that the position of the at least one point of engagement can be changed along the reefing finger as reefing progresses or the position of the point of engagement on the reefing finger is changed.
