A method of packaging a plurality of food containers and a package for food containers are disclosed. The method is fast and inexpensive and optimizes the use of cardboard or paperboard to make the package without plastics and may be used in the mass production of packaging for containers. The package is defined by a plurality of containers placed on a tray of optimal dimensions according to the dimensions of the containers. The tray is creased and has two side flaps that can be rotated to attach to the side faces of the containers by glue. The extension of the flaps is proportional to the height of the containers and the flaps can be punched in order to have aesthetically appreciable shapes and to reduce the bulk and the risk of breaking the package made.

A mattress packaging device includes a first packaging device and a second packaging device, where the first packaging device includes a first folding and vertical sealing mechanism and two corner sealing mechanisms, the first folding and vertical sealing mechanism is configured for folding and vertically sealing a packaging material opening at the end of a mattress, and the corner sealing mechanisms are configured for folding and transversely sealing front corner and rear corner of packaging material on two sides of the mattress; the second packaging device includes two second folding and vertical sealing mechanisms and two first transverse sealing mechanisms, the second folding and vertical sealing mechanisms are configured for folding and vertically sealing the packaging material on two sides of the mattress, and the two first transverse sealing mechanisms are configured for transversely sealing the packaging material on two sides of the mattress.

An apparatus and method for automatically rolling a napkin around a set of dining utensils, wherein the apparatus can repeat the method quickly to individually wrap a plurality of sets of utensils in napkins. The apparatus comprises a housing for a first transfer unit for receiving a set of unwrapped utensil and a napkin and configured to automatically deliver the unwrapped utensils and napkin to a platform for wrapping. A lift plate holds a plurality of napkins and delivers a single napkin to unwrapped silverware. A rolling assembly rotatable around the unwrapped utensils and the napkin is configured to hold the utensils and to roll the napkin around the unwrapped utensils and to deliver the wrapped utensils to a second transfer unit configured to provide the wrapped utensils to a bin for storage.

A plastic film sealing and packaging device includes a chassis, a conveyance device for conveying articles-to-be-packaged, at least one pair of plastic film conveyance trays, at least one plastic film sealing mechanism and at least one heat-shrinking device. The conveyance device extends through front and rear ends of the chassis. The plastic film conveyance trays are set at two sides of the chassis to supply strap-like packaging plastic films. The plastic film sealing mechanism is arranged behind the plastic film conveyance trays to have packaging plastic films supplied from the plastic film conveyance trays sealed and combined as a combined film that is set horizontally set so that the articles-to-be-packaged conveyed by the conveyance device are allowed to contact the packaging plastic film to have the packaging plastic film wrapping around a closure site of the article-to-be-packaged. The package plastic film is then sealed by the plastic film sealing mechanism.

A folding arrangement including a flap lifting assembly located at a drop conveyor discharge end and including a pivoting arm with a flap engaging surface that is movable between a first, flap-lifting position and a second, pass-through position is provided. A folding assembly includes a receiving conveyor with a receiving conveyor feed end positioned below the drop conveyor discharge end, and a folding finger above the receiving conveyor feed end. The product-substrate combination is driven by the drop conveyor into contact with the flap engaging surface in the first position to lift the flap as the product-substrate combination is discharged from the drop conveyor discharge end towards the receiving conveyor feed end, and the folding finger contacts the flap of the product-substrate combination to complete folding of the flap to a second angled position onto the product as the product-substrate combination pivots the flap engaging surface to the second position.
