发明名称 Wrapping material and method of forming wrapped package
摘要 A wrappable material for wrapping products comprising means having marginal edge portions; and at least first and second bondable and heat shrinkable means, each being foldably connected to opposed marginal edge portions, and each one being foldable over the other in overlapping relationship. The opposed first and second bondable and heat shrinkable means comprises monoaxially shrinkable plastic material which is shrinkable in a direction generally transverse to the direction of the opposed edge portions. Also disclosed is a wrapped package for storing a quantity of materials comprising means having a bottom portion which receives thereon the material which is wrapped and has marginal edge portions; and having at least a pair of flap means, each one being foldably connected at one end to corresponding opposed marginal edge portions. Each of the flaps having free end portions in an overlapped relationship with the other so as to enclose the wrapped material. The overlapped end portions are bonded together, and the material of the flap means being heat shrunk onto the material wrapped. The method comprises steps of placing material to be wrapped onto a bottom portion of first means having opposed and foldable end portions and heat shrinkable foil flaps connected to opposed marginal edge portions of the bottom portion, folding the free end portions of the flaps over the material to be wrapped, in an overlapping manner, bonding the overlapped free end portions to one another, thereafter, heating the surface of the shrinkable flaps to cause shrinkage thereof, and closing the foldable end portions of the reinforced material over the heat shrunk flaps.
