A packaging box sheet capable of transporting without consuming space, assembled to obtain a box. The box sheet includes: a mounting board; and a decorative paper on the mounting board surface; where the mounting board includes: a bottom board; and first and second side boards connected to two sides sharing one apex at the bottom board; where the decorative paper includes: a first paper portion affixed to the bottom board; a second paper portion corresponding to the second side boards, where the second paper portion is connected to the first paper portion, and where the second paper portion is separated from the second side boards; and a third paper portion connected to the first paper portion and where the third paper portion projects from the first side boards toward the second side boards; and wherein the second and the third paper portion have an adhesive layer and a release paper.

The invention provides an amorphous copolymerized polyester raw material for a film. The raw material contains ethylene terephthalate as a main constituent component, and contains from 18% by mol to 30% by mol of neopentyl glycol when a total amount of a glycol component in a total polyester resin component is taken as 100% by mol. The raw material contains from 8% by mol to 16% by mol of a constituent unit derived from diethylene glycol in the total amount (100% by mol) of the glycol component in the total polyester resin component. The raw material has an intrinsic viscosity of from 0.70 dl/g to 0.86 dl/g. The raw material has a melt viscosity of 200 Pa.Math.S or less, when measured at a shear rate of 6080/S at 250° C.

A tray container includes a paper-based material having a number of sides extending from a container bottom. Each side has a proximal end that is contiguous with the container bottom and a distal end that is configured to fold into a bonding surface and a reinforced portion. The bonding surface and the reinforced portion each include two layers of the container material. The tray container has a perimeter bonding surface that includes each bonding surface of the container sides. A support ring is attached to the perimeter bonding surface, defining a cover bonding surface to which a film or mesh cover may be bonded.
