Hydrocarbon system synthetic paper-pulp fibre length compared with natural pulp is short and drainage is good, and its result is when the alkene that will be had characteristics that
When being that synthetic paper-pulp is used as fibrous raw material, the paper machine in copy paper process when package paper is manufactured by wet paper manufacturing method
In wet end, through hole or low paper pulp accumulation portion can be easily formed on l Water Paper, therefore also the formation with watermark portion is easy
The advantages of.The invention that the package paper of the present invention is based on such cognition and completed.
Opacity (part (the non-watermark in addition to watermark portion specified in the JIS P8149 of the package paper of the present invention
Portion) opacity) be preferably 35~80%, more preferably 40~65%.The opacity of package paper can be by right
Species, the content of olefin-based synthetic paper-pulp carry out appropriate adjustment to adjust.
In addition, other action effects as olefin-based synthetic paper-pulp, the effect of resiliency is also improved.That is, comprising day
The package paper of the invention of right paper pulp and olefin-based synthetic paper-pulp is not with comprising natural pulp but including olefin-based synthetic paper-pulp
Common paper compare, there is low-density and the high speciality of resiliency, be consequently adapted to the bag of article for making full use of its resiliency
Fill purposes.
The density of the package paper of the present invention is preferably 0.2~0.6g/cm3, more preferably 0.3~0.5g/cm3.Separately
Outside, the package paper of the present invention (is formed into through hole or low paper by method 1) or 2) described later on l Water Paper before it is dried
The method for starching accumulation portion) when being manufactured, i.e., (l Water Paper exists " paper pulp or the paper pulp part fewer than periphery is not present " in l Water Paper
Turn into the part in watermark portion after drying) in the formation process of l Water Paper, by the formation reservations for purposefully hindering watermark portion
When the accumulation of paper pulp in point is to form, the density in the watermark portion in so obtained package paper and the non-watermark portion on its periphery
It is identical or lower.On the other hand, the watermark portion (white watermark) in the paper that patent document 1 is recorded is due to additional by the machine after copy paper
The hot-pressing processing of work forms polyolefin series fiber softening melting, therefore speculates that the non-watermark portion on its density ratio periphery is high.
In addition, the paper that patent document 1 is recorded implements heat by a part for the homogeneous paper of the weight per unit area to paper pulp
Pressure handles and forms watermark portion, and due to its manufacture method, hot-pressing processing is not carried out in watermark portion and its periphery that hot-pressing processing is formed
Non-watermark portion there is no substantial variations in the amount of paper pulp.On this point, watermark portion of the invention is as it was previously stated, in the absence of paper
Slurry or the paper pulp part fewer than periphery (non-watermark portion), with by dry paper by hot-pressing processing and the watermark portion that is formed not only
All it is different in terms of amount in terms of the density and in paper pulp.The relatively little of watermark portion of amount of such paper pulp can not pass through paper
Hot-pressing processing formed, but as described later, by purposefully hindering the formation in watermark portion pre- in the formation process of l Water Paper
The accumulation of the paper pulp in part is determined to be formed.
In addition, as described in patent document 1, the watermark portion formed by hot-pressing processing is also dependent upon hot-pressing processing
Condition, but the olefin-based synthetic paper-pulp melting softening generally under hot-pressing processing therefore is unable to maintain that fibre morphology, with periphery
The non-watermark portion that hot-pressing processing is not carried out compares, and Inter-fiber voids are small, according to circumstances Inter-fiber voids substantially completely disappear and can
It may be the membranaceous form of film sample.On this point, the fibre morphology in the watermark portion of the invention without hot-pressing processing is able to
Maintain, compared with the non-watermark portion of periphery, the form as fiber assembly does not have substantial difference.
The resiliency used pack of package paper is evaluated with the compressive strength of paper, and the numerical value of compressive strength is bigger, the bag
The evaluation of the resiliency of dress paper is higher.But the numerical value of compressive strength it is excessive when, due to package paper rigidity increase, because
This package paper is difficult to the shape for following packed article, there is the worry of the function reduction as package paper.In view of above feelings
Condition, the compressive strength of package paper of the invention is preferably 0.2~0.9, more preferably 0.4~0.6.The pressure of package paper
Contracting intensity (resiliency) can carry out appropriate adjustment to adjust by the species to olefin-based synthetic paper-pulp, content.In addition, in order to incite somebody to action
The compressive strength of package paper is adjusted to above range, and as described later, package paper is being manufactured by wet paper manufacturing method
When copy paper process in, paper (package paper) obtained from preferred pair dries l Water Paper without pressing.
" compressive hardness of package paper " is determined using known KES compression tests, by subtracting the measured value from 1
To calculate the compressive strength of package paper.That is, " compressive strength=1- compressive hardnesses ", the numerical value of compressive hardness is bigger, the packaging
With compressive strength (resiliency) the more lower assessment valency of paper.The assay method for having used the compressive hardness of KES compression tests is use
Circular flat (2cm2) stress of measure when measure object (package paper) compress method, the straight line that compressive hardness compresses
Property represent, its numerical value is closer to 1, then it represents that measure object is harder.
The assay method of compressive strength is more specifically illustrated.The KES compression tests used in measure possess with
The area of the contact portion of measure object is 2cm2Metal pressurized, as the KES compression tests so formed, can arrange
Enumerate and for example possess discoideus metal pressurized, Kato Tech Co. Ltd. systems trade name " KES-G5 ".Will measure
Object (package paper) is fixed in the sample mounting table of KES compression tests, from the top of the measure object by pressurized with
Defined press-in speed is pressed into the thickness direction of measure object with defined pressure, determines the maximum of now stress.Make to add
The press-in speed of pressure is 50~500gf/cm in 0.0067~0.02mm/ seconds, press-in pressure2In the range of.To measure object
Area be 100cm2Each region implement the measure of the maximum stress at any 3, by so obtained multiple measured values
Compressive hardness of the average value as measure object, the compressive strength of measure object is calculated by following formula.
Compressive strength=1- compressive hardnesses
Resiliency (compressive strength) or paper power etc. as package paper key property by possessed by its package paper
The not small influence of the pattern in watermark portion.That is, the compressive strength of package paper can be because of the vertical view shape in the watermark portion in its package paper
Shape, size, quantity etc. and change.Particularly, if weight per unit area is 30g/m2Such low weight per unit area below
Package paper has that the absolute magnitude of the paper pulp of positive acting is few to resiliency or paper power, therefore the watermark portion in the package paper
Influence of the pattern to resiliency etc. is very important.Moreover, the watermark portion of the present invention is as it was previously stated, in the absence of paper pulp or paper pulp ratio
The few part of periphery (non-watermark portion), its result in order to further positively meet key property as package paper, this
The relatively little of part of sample paper pulp in package paper compared with locally lying in, more preferably discrete in package paper entirety or scatterplot
Exist shape.
In the present invention, the pattern in watermark portion is not particularly limited, such as can be from one end of package paper to another
Hold continuous wire is such, the watermark portion of " shape do not surrounded by non-watermark portion " (non-closed shape) is multiple discretely to exist
Form, but in view of the key property of the package paper such as resiliency, preferably " multiple watermark portion scatterplot shapes are present in package paper
Overall and each watermark portion is surrounded the pattern for the shape for forming closure by non-watermark portion ".The package paper of each embodiment described later
For the specific manifestation of the pattern in the preferable watermark portion.The plan view shape in each watermark portion is not particularly limited, can from toroidal,
Arbitrarily selected in wire such as more than elliptical shape, triangular shaped, quadrangle polygonal shape, straight line or curve etc., separately
Outside can also be by two or more different combination of plan view shape.
From the viewpoint of the key property as package paper such as resiliency is positively met, 1 in package paper
The area in watermark portion is preferably 1.5cm2Below, it is more preferably 0.01~1.0cm2。
In addition from the same viewpoint, when the area in 1 watermark portion is in above-mentioned preferable scope, package paper it is every
100cm2The quantity in the watermark portion of area is preferably more than 5, more preferably 10~600.
In addition from the same viewpoint, the distance (spacing in watermark portion) between the center between adjacent watermark portion is preferred
For 1~50mm, more preferably 3~30mm.
In addition, from the viewpoint of the action effect for more reliably playing previously described olefin-based synthetic paper-pulp, this hair
The content of olefin-based synthetic paper-pulp in bright package paper is excellent relative to the mass parts of natural pulp 100 in the package paper
Elect 1~70 mass parts, more preferably 5~40 mass parts as.Olefin-based synthetic paper-pulp relative to natural pulp content mistake
When few, there is the worry for the action effect that can not fully obtain previously described olefin-based synthetic paper-pulp, when olefin-based synthetic paper-pulp
When excessive relative to the content of natural pulp, there is sheet strength to die down, worry as the intensity needed for wrapping paper can not be obtained.
The package paper of the present invention can be manufactured by known wet paper manufacturing method, specifically be carried out by following processes
Manufacture：Two paper pulp are ferreted out to form l Water Paper from the dispersion liquid of natural pulp and synthetic paper-pulp using copy paper net, it is then that this is wet
Paper is dried.The accumulating amount in above-mentioned watermark portion, i.e., the through hole penetrated package paper through-thickness or paper pulp is fewer than periphery
Low paper pulp accumulation portion can as to make l Water Paper dry obtained from paper press outer surface apply relief pattern roller the appearance
Face carries out figuration, the method (dry-pressing pattern method) of relief pattern progress figuration is transferred to the paper to be formed, but press such
In the method for pressing dry dry paper, load that the effect that has the resiliency that previously described olefin-based synthetic paper-pulp brings to improve reduces
Sorrow.Therefore, from the viewpoint of the excellent package paper of resiliency is positively obtained, formed not on l Water Paper preferably before it is dried
