A blank for a box made from an expandable material, which is initially molded to be substantially flat and in which folds forming hinges are to be made to enable the formation of the box. The tooling defines the shape of the blank is such as to provide a thickness of the expanded material that is less than the thickness of a major portion of the blank, in which folds are to be made having defined edges, generally in the direction of each fold; the fold and subsequently applying pressure along an area where folds are to be permitted to reduce the blank are made without removing material therefrom for providing hinges to permit formation of the box. A related method for making the blank and a box that is made from the blank are further provided.

The invention herein is related to the recycling industry in general, it is specifically related to a plastic container, preferably made of PET (polyethylene terephthalate), which can be molded, preferably, through blown air, defined by a back face, a front face, two lateral face, a lower face and an upper face, the multipurpose jaba-type agricultural container, and its manufacturing process, is cut manually or with a machine, and the front face is removed, to define an internal cavity and form the jabs-type container defined by a back wall and four perimeter walls, it has enough resistance to hold the weight of the products it contains, it also has a perimeter tab, on the external face of the lower edge, which allows the vertical stacking of several containers, with enough strength to evenly fold the weight, when being stacked, such container also contains several vertical ribs on the perimeter walls, and a main perimeter rib used as reinforcement elements, as well as holes on the sides that allow the release of gas generated by the products inside the container.

Packing tray for protecting fragile and perishable food items, such as pears, which allows fruit items of varying dimensions and weights to be held securely in each pocket, and which allows a plurality of stacked trays and fruit to be packaged in boxes (e.g., standard carton sizes). The tray is a plastic foam sheet having a top wall and a plurality of recessed cell pockets, each cell pocket having a relatively thinner cell sidewall with expandable (accordion-like) flutes, and a relatively thicker bottom wall also with expandable flutes. This construction allows the cell bottoms in adjacent pockets and in adjacent trays of the stack to move relative to one another to accommodate various sizes and weights of fruit while still protecting the fruit from damage.
