US 2021/0229899 A1 · FRUIT BAG FOR A FRUIT OF FRUIT TREE WITH NANO-LAMINATION FILM AND MANUFACTURING METHOD THEREOF

Abstract

Provided are a fruit bag and a method thereof, for example, a fruit bag for a fruit of a fruit tree may include: an inner surface configured to surround the fruit; an outer surface configured to exposed to an outside; an opening formed in a predetermined size at the same position of the inner surface and the outer surface; a nano membrane generated by an electrospinning of a polymer solution as a raw material for nano-fibers; a non-woven fabric for strength reinforcement laminated on one or both sides of the nano membrane and a nano-lamination film covering the entire surface of the opening thereby while maintaining excellent air permeability, it is possible to properly maintain the humidity and against various external environmental effects.
