Description
- This application claims the benefit under 35 U.S.C. §119 from Korean Patent Application No. 10-2006-19582, filed on Feb. 28, 2006, in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a multi-layered packaging film, a packaging bag, and a package and a packaging method using the multi-layered packaging film and the packaging bag.
- 2. Description of the Related Art
- Generally, products, such as household appliances, office machines, furniture, and precision machinery and tools, are packaged with a packaging box, etc. so as to prevent them from being scratched or damaged during storage and delivery. In this case, to protect the products from impacts, as well as from moisture, dust, mold, etc., the products are wrapped with a packaging film such as a polyethylene film, fixed into a cushion member such as a resin foam and then inserted into the packaging box.
- However, even though the products are packaged as above, there may arise a problem that a friction is produced between the product and the packaging film so as to peel away a paint or coating layer from the product.
- Recently, electronic appliances, such as air conditioners, handsets, notebooks, refrigerators, etc., are being designed with more attention to aesthetic details. As there is no difference in function or performance between the same kinds of electronic appliances, there is growing recognition that the electronic appliances are being treated as furniture, and consumers prefer an electronic appliance with a smart design and a fashionable color above other electronic appliances.
- Accordingly, electronic appliances, which not only have more various and luxurious colors and patterns, but also present an ornamental value, are coming out on the market.
- To present such a fashionable atmosphere, the electronic appliances are usually coated with high glossy colors, e.g., high glossy black colors, which bring up the image of a piano coating and feel as if it is a luxurious crystal in a bright place.
- However, the electronic appliances coated with the high glossy colors as above are easily scratched even by a small impact and the scratched portion is easily noticeable, as compared with a general electronic appliances, which are not coated with high glossy colors. Accordingly, it is very important for the packaging material, such as a packaging film, to protect the electronic appliances.
- To prevent the electronic appliances from being scratched, there has been used a method that a protecting film is attached on outer surfaces of the electronic appliances to protect them. However, since the work of attaching the protecting film is troublesome and inefficient, productivity may be reduced. Further, since material cost of the protecting film is expensive, manufacturing costs may be increased. Also, bubbles may be produced in or on the outer surfaces of the electronic appliances on which the protecting film is attached, so that a quality in the exterior of the electronic appliances is deteriorated.
- Illustrative, non-limiting exemplary embodiments of the present invention address at least the above problems and/or disadvantages and provide at least the advantages described below. Accordingly, an apparatus consistent with the present invention provides a multi-layered packaging film that can prevent products from being scratched during packaging and delivery.

- These and/or other aspects and advantages of the present invention will become apparent and more readily appreciated from the following description of the exemplary embodiments, taken in conjunction with the accompanying drawings of which:
-
FIG. 1 is a perspective view illustrating a packaging material (i.e., a packaging bag) in accordance with an exemplary embodiment of the present invention; -
FIG. 2 is a cross section view taken along line II-II ofFIG. 1 ; -
FIG. 3 is a schematic cross section view illustrating a package in which the packaging bag in accordance with the exemplary embodiment of the present invention is applied; and -
FIG. 4 is a magnified view of a portion A ofFIG. 1 - Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The exemplary embodiments are described below in order to explain the present invention by referring to the figures.
- Referring to
FIGS. 1 and 2 , there is illustrated apackaging material 1 to package anobject 3 in accordance with an exemplary embodiment of the present invention. Thepackaging material 1 may be apackaging bag 2 to receive the object therein. The present invention is not limited to thepackaging bag 2, however. - The
packaging bag 2 comprises twomulti-layered sections 10 adjacent with each other. Each of the twomulti-layered sections 10 includes anouter film 11, and aninner film 13 layered inside theouter film 11 to contact theobject 3 to be packaged. Theouter film 11 and theinner film 13 are layered, so that they are not attached with each other, but separated from each other. Accordingly, theouter film 11 is movable with respect to theinner film 13. - The
outer film 11 and theinner film 13 are formed to have a coefficient of friction different from each other. To be more specific, theouter film 11 is formed of a material, e.g., a high-density polyethylene (HDPE), having a small coefficient of friction, and theinner film 13 is formed of a material, e.g., a low-density polyethylene (LDPE), having a large coefficient of friction. At this time, theinner film 13 can be formed in the shape of foam to carry out a cushioning function. In this case, theinner film 13 functions to protect theobject 3 from an impact, as well as from moisture, dust, mold, etc. - The
packaging bag 2 is configured, such that the twomulti-layered sections 10 at three edges E1, E2 and E3 thereof are joined with each other and at one edge E4 thereof, separated from each other, thereby forming a pocket. The joining between the twomulti-layered sections 10 at the three edges E1, E2 and E3 can be carried out by a hot seal process. - Here, although the
multi-layered sections 10 are illustrated and explained as joined with each other at the three edges E1, E2 and E3 thereof, the present invention is not limited thereto. For instance, thepackaging bag 2 can be configured, such that themulti-layered sections 10 are joined with each other at one or more of four edges E1, E2, E3 and E4 thereof. - The
object 3 may be, but is not limited to, household appliances such as a LCD monitor, a LCD TV, an air conditioner, a handset, a refrigerator, a home theater, etc., household goods such as furniture, etc., or machinery and tools, which have a surface polished at a high level. - Referring to
FIG. 3 , there is illustrated apackage 30 to which thepackaging bag 2 is applied. Thepackage 30 includes apackage bag 2, acushion member 31, and apackaging box 33. Thepackage bag 2 constitutes thepackaging material 1 and has the same structure as described with reference toFIGS. 1 and 2 . Thecushion member 31 is disposed to contact an outer surface of theouter film 11. Thepackaging box 33 receives thecushion member 31. - An operation of packaging the
object 3 by using thepackaging bag 2 is as follows. - First, the
object 3 is inserted between the twomulti-layered sections 10 of thepackaging bag 2, so that it comes in contact with theinner film 13 of thepackaging bag 2. - Then, the
cushion member 31 is provided outside theouter film 11 to fix the outer surface of theouter film 11. - Thereafter, the
cushion member 31 in which theobject 3 inserted between the twomulti-layered sections 10 is contained is inserted into and fixed in thepackaging box 33. As a result, the operation of packaging theobject 3 is completed. - If an external impact is applied to the
package 30 packaged as above, theobject 3 moves along with theinner film 13 because it contacts theinner film 13 having the large coefficient of friction. Also, thecushion member 31 moves along with theouter film 11 because it contacts theouter film 11 having the low coefficient of friction. As a result, a place, in which a movement is generated in a largest scale, is between theinner film 13 and theouter film 11. Accordingly, theobject 3 is prevented from being scratched or damaged. - As illustrated in
FIG. 4 , thepackaging bag 2 can further include asubsidiary film 14 layered directly on the outer side of theinner film 13, with a space provided between thefilm 14 and theouter film 11. Thesubsidiary film 14 is preferably formed of a material, e.g., a high-density polyethylene (HDPE), having a coefficient of friction, which is lower than that of theinner film 13 and which can most effectively move theouter film 11 with respect to thesubsidiary film 14. - Accordingly, if the external impact is applied to the
package 30, theouter film 11 is more effectively moved because it comes in contact with thesubsidiary film 14 having the coefficient of friction, which is lower than that of theinner film 13. - The
subsidiary film 14 also functions to prevent theinner film 13 formed of the low-density polyethylene (LDPE) from being easily torn. - As previously noted, although the
packaging material 1 in accordance with the exemplary embodiment of the present invention has been described as thepackaging bag 2 in the shape of the pocket, it is not limited thereto. For instance, thepackaging material 1 in accordance with the exemplary embodiment of the present invention can be formed in such a manner that a singlemulti-layered section 10 having aninner film 13 and anouter film 11 wraps around the outer surface of theobject 3. In this case, it is also important to bring theobject 3 in contact with theinner film 13 having a large coefficient of friction and to dispose theouter film 11 having a small coefficient of friction most outside. - According to the exemplary embodiments of the present invention as described above, the packaging material, i.e., the packaging bag, is configured, such that if an external impact is applied to the package, the outer film having the small coefficient of friction moves along with the cushion member with being in contact therewith. Accordingly, a movement of the object, which comes in contact with the inner film having the large coefficient of friction, to the inner film is reduced, thereby preventing the object from being scratched or damaged.
- Also, according to the exemplary embodiments of the present invention, the packaging material has a multi-layered structure having the outer film of high density and the inner film of low density. Accordingly, a foaming gas such as a pentane gas or butane gas, which is possible to remain in the cushion member, is blocked from being conveyed to the object. The foaming gas, which is used to form the cushion member in the shape of foam during the foaming, usually remains in the foamed cushion member for about a month.
- Although a few exemplary embodiments of the present general invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
