Description
FIELD OF THE INVENTION
[0001] The present invention relates to a ream wrapper made of an
unbleached (brown) paper or a semi-bleached (tan) paper with a
white poly or colored poly coating.
BACKGROUND OF THE INVENTION
[0002] Reams (i.e., 500 sheets) of cut paper (8 1/2.times.11, etc.)
for copy machines, computers, printers, and other applications are
most commonly packaged for shipping, storage, and retail sale in
ream wrap made of various wrap materials. These wrap materials
traditionally have been 25-pound per 3,000 sq. ft. paper laminated
to a 25-pound paper per 3,000 sq. ft. with 7 to 12 pounds per 3,000
sq. ft. of polyethylene. In many cases, the two papers were
bleached or white papers. The outside of the wrapper was generally
printed to identify the paper mill or distributor of the product.
In some cases, the wrapper would be bleached (white) 25-pound paper
on the outside, but an unbleached or brown paper on the inside
laminated together with polyethylene. This type of wrapper was less
expensive and perceived as more environmentally friendly since the
inside paper did not go through a bleaching process. The white
paper on the outside still maintained a good printing surface.
[0003] Ream wrapper has recently moved from the lamination of two
papers with polyethylene to a heavier weight sheet of paper,
usually 40 to 60 pounds per 3,000 sq. ft., coated with polyethylene
on one side. This product is generally stronger and easier to work
with than the laminated product. With this change, it was no longer
possible to use the unbleached (brown) or semi-bleached (tan) paper
if a print surface was desired on the outside of the wrapper, as
only one sheet of paper was being used. As retail and store
distribution of reamed paper has increased, manufacturers have
placed more emphasis on a ream wrap's improved printing surface to
enhance graphics and provide eye-appealing wrapped product for the
customer. Equally important as the aesthetic appeal of the outer
package is the identification of the manufacturer of the wrapped
paper through the printed graphics or the color of the outer
packaging.
[0004] Another disadvantage of current and conventional ream wraps
is that they are non-transparent and do not permit the consumer to
view the color of the reamed paper encased in the wrapper. Viewing
the contents of the wrapped products is important, in particular,
when reams of colored paper (other than white) are contained in the
package.
SUMMARY OF THE INVENTION
[0005] A ream wrapper comprising an unbleached (brown) paper or a
semi-bleached (tan) paper with a white poly coating. It is an
object of the present invention for the ream wrapper to have a
white print surface for the outside of the ream wrap. It is an
object of the present invention for the ream wrapper to provide a
moisture barrier. It is an object of the present invention for the
paper to have a weight between about 25 to 75 pounds per 3,000 sq.
ft. It is an object of the present invention for the coating to
have a weight of about 7 to 15 pounds per 3,000 sq. ft. It is an
object of the present invention for the unbleached paper to be 40
pound bag and laminating Kraft, 50 pound extensible Kraft, and 60
pound converting Kraft. It is an object of the present invention
for the white poly coating to be made by mixing polyethylene or
polypropylene with a white dye or pigment.
[0006] The present invention relates to a ream wrapper comprising
either an unbleached (brown), semi-bleached (tan), or bleached
(white) paper with a colored poly coating. It is an object of the
present invention for the paper to have a weight between about 25
to 75 pounds per 3,000 sq. ft. It is an object of the present
invention for the paper to have a weight between about 40 to 60
pounds per 3,000 sq. ft. It is an object of the present invention
for the coating to have a weight of about 7 to 15 pounds per 3,000
sq. ft. It is an object of the present invention for the colored
poly coating to be made by mixing polyethylene, polypropylene, or a
combination with a dye or pigment. It is an object of the present
invention for the ream wrapper to provide a high quality printing
surface for the outside of the ream wrap in a color that enhances
printing graphics, instantly identifies a manufacturer of the
wrapped paper product, and/or identifies the color of the paper
encased in the ream wrap. It is an object of the present invention
for the ream wrap to act as a moisture barrier, protect against
physical damage, and use, more environmentally friendly unbleached
(brown) or semi-bleached (tan) paper while still providing an
enhanced printing surface. It is an object of the present invention
for the ream wrap color to match the color of the paper contained
inside the wrapped package.
[0007] The present invention relates to a method of preparing a
colored poly ream wrapper comprising: mixing polyethylene,
polypropylene, or a combination with a dye or pigment to form a
poly mixture. The mixture is then coated on either side of about a
40 or 60 pound unbleached (brown), semi-bleached (tan), or bleached
(white) paper.
[0008] The present invention relates to a method for making a white
poly coated ream wrap comprising: mixing a blend of low density
polyethylene or polypropylene with a white pigment or dye additive
resulting in a white opaque film. The white film is coated on an
unbleached (brown) paper or a semi-bleached (tan) paper.
[0009] The present invention relates to a method of making a
colored poly coating comprising: mixing a blend of low density
polyethylene or polypropylene with a blue pigment or dye additive
resulting in a blue opaque film. The blue opaque film is coated on
an unbleached (brown), semi-bleached (tan), or unbleached (white)
paper.
[0010] It is an object of the present invention for the poly
coating to be mixed to match a particular shade recognizable of a
manufacturer. It is an object of the present invention for the poly
coating to result in a high gloss printing surface, an
eye-appealing ream wrap package, a moisture barrier, and a strong
packaging material that protects wrapped paper from physical
damage. It is an object of the present invention for the
polyethylene, polypropylene, or polyethylene-polypropylene mix to
be blended with a colored dye or pigment that matches the color of
the paper being encased in the ream wrap.
[0011] The present invention relates to a ream wrapper comprising:
a bleached, semi-bleached or natural paper substrate having a basis
weight of between about 25-75 pounds/3,000 sq. ft. The substrate is
coated on one side with about 7-15 pounds of polyethylene,
polypropylene, polymer resin, copolymer and/or terpolymer resins
alone or blended with polyester. The coating is white or colored
with a pigment or dye additive that results in a white or colored
opaque product.
[0012] The present invention relates to a ream wrapper comprising:
a solid plastic film substrate coated with a white or colored poly
coating which results in a colored or white film wrapper.
[0013] It is an object of the present invention to allow the use of
the more friendly environmentally unbleached (brown) paper or a
semi-bleached (yellowish) paper which is also more environmentally
friendly in the pulping process, while still providing a white
printing surface.
[0014] An object of the present invention is to provide a wrapper
that promotes instant recognition of the manufacturer and an
improved printing surface as well as an attractive outer package
for the consumers and end-users to view on office and retail
shelves.
DETAILED DESCRIPTION OF THE INVENTION
[0015] In an embodiment of the present invention a ream wrapper
comprises an unbleached (brown) paper or a semi-bleached (tan)
paper with a white poly coating. The white polyethylene coating
results in a white print surface for the outside of the ream
wrap.
[0016] Examples of unbleached paper are 40 pound bag and laminating
Kraft, 50 pound extensible Kraft, and 60 pound converting
Kraft.
[0017] In one embodiment, the white poly coating is made by mixing
polyethylene or polypropylene with a white dye or pigment.
[0018] In one example, the white poly coating is made by mixing a
blend of low density polyethylene or white polypropylene with a
white pigment or dye additive resulting in a white opaque film. The
white poly coating is then coated on the unbleached (brown) paper
or a semi-bleached (tan) paper. The white polyethylene coating
results in a white print surface for the outside of the ream
wrap.
[0019] In a further embodiment, the ream wrapper comprises an
unbleached (brown), semi-bleached (tan), or bleached (white) paper
having a weight between about 40 to 60 pounds per 3,000 sq. ft.
coated with about 7 to 15 pounds per 3,000 sq. ft. of a colored
poly. The colored poly coating results in an enhanced printing
surface for the outside of the ream wrap as well as a colored outer
package that provides instant recognition of either paper
manufacturer or the color of the paper encased in the ream
wrap.
[0020] In an embodiment, the colored poly coating is made by mixing
polyethylene, polypropylene or a combination with a dye or pigment.
The poly mixture is then coated on either side of an about 40 to 60
pound unbleached (brown), semi-bleached (tan), or bleached (white)
paper.
[0021] In one embodiment, the colored poly coating is made by
mixing polyethylene or polypropylene with a blue dye or pigment.
The blue poly mixture is then coated on either side of an about 40
to 60 pound unbleached (brown), semi-bleached (tan), or bleached
(white) paper.
[0022] In an example, the colored poly coating is made by mixing a
blend of low density polyethylene or polypropylene with a blue
pigment or dye additive resulting in a blue opaque film. The
colored poly mixture is then coated on the unbleached (brown),
semi-bleached (tan), or unbleached (white) paper.
[0023] In a preferred embodiment, the blue poly coating is mixed to
match the particular shade of blue recognizable in the packaging of
an identified paper manufacturer. The blue poly coating also
results in a high gloss printing surface, an eye-appealing ream
wrap package, a moisture barrier, and a strong packaging material
that protects the wrapped paper from physical damage.
[0024] In another embodiment, the polyethylene, polypropylene, or
polyethylene-polypropylene mix is blended with a colored dye or
pigment that matches the color of the paper being encased in the
ream wrap. The colored poly coating then results in a colored
wrapper that enables consumers and end-users to identify the color
of the wrapped product.
[0025] A preferred embodiment comprises a paper substrate
(bleached, semi-bleached or natural) with a basis weight of between
about 25-75 pounds/3,000 sq. ft., and being of any paper type
(e.g., machine-glazed, machine-finished, clay-coated, etc.). The
substrate is coated on one side with about 7-15 pounds of
polyethylene or polypropylene (poly, polymer resin, copolymer
and/or terpolymer resins alone or blended with polyester) that is
white or colored with a pigment or dye additive that results in a
white or colored opaque product. The final product may or may not
be printed.
[0026] A further embodiment is to use a solid plastic film
substrate and cover it with a white or colored poly coating to
result in a colored or white film wrapper (printed or
nonprinted).
