## Abstract

A styrofoam material 2 is placed in a corrugated carton 1, and a plastic bag 3 is then loaded into the corrugated carton 1. Air between any two of the corrugated carton 1, the styrofoam material 2, and the plastic bag 3 is evacuated so that the plastic bag 3 is adhered onto dented portions 2a for product placement of the styrofoam material 2, and inner surfaces of the corrugated carton 1. As a result, products 4 can be easily placed on the styrofoam material 2 onto which the plastic bag 3 is loaded without the products 4 getting snagged on the plastic bag 3 and the plastic bag 3 being torn.

## Claims

### Claim 1

A packaging system comprising:
a packaging carton;
a single pad formed of shock absorbing material; and
a deaerating-duct having deaerating nozzles formed thereon for sucking air,
wherein a plurality of holes for deaeration is formed so as to penetrate through a first surface of the single pad, which is brought into contact with an inner surface of said packaging carton when said single pad is placed in said packaging carton,
wherein said plurality of holes for deaeration is also formed so as to penetrate through a second surface of the single pad on which a product to be packed is placed via a thin film member,
wherein said nozzles are inserted into said plurality of holes for deaeration via a deaerating-duct insertion openings formed through said packaging carton,
wherein said deaerating-duct is provided under a bottom surface of said packaging carton, such that said deaerating duct is provided outside of said packaging carton, and
wherein said deaerating-duct insertion openings are formed through said bottom surface of said packaging carton.

### Claim 2 (depends on 1)

The packaging system according to claim 1, wherein the plurality of holes for deaeration are formed on a side of a dented portion provided in the second surface, the dented portion for placement of the product.

### Claim 3 (depends on 1)

The packaging system according to claim 1, further comprising at least one dented portion in the second surface, the dented portion for placement of the product therein,
wherein at least two holes for deaeration are formed in the dented portion.

### Claim 4 (depends on 1)

The packaging system according to claim 1, wherein the plurality of holes are enclosed within the shock absorbing material.

### Claim 5 (depends on 1)

The packaging system according to claim 1, wherein the plurality of holes are fully enclosed by the shock absorbing material around the perimeter of the holes.

### Claim 6 (depends on 1)

The packaging system according to claim 1, wherein positions of said plurality of holes for deaeration correspond, respectively, to positions of said deaerating-duct insertion openings formed through said packaging carton.
