JPH1181195A - Buffer paper and its production - Google Patents

Abstract

PROBLEM TO BE SOLVED: To produce a buffer paper capable of being produced by using a recycled paper hardly generating a harmful gas when producing and burning the paper as a raw material by partially pressing two or more sheets of embossed paper to provide an adhering paper, and sticking the adhering paper on a single-faced corrugated fiberboard in stripes to provide a joined paper. SOLUTION: The objective buffer paper is obtained by forming at least two or more sheets of embossed paper 1, partially pressing two or more sheets of the embossed paper to form an adhering paper 3 adhering at the pressed parts 2, and sticking the adhering paper 3 on a single-faced corrugated fiberboard 4 in stripes to provide a joined paper. The adhering paper 3 adhering the multiple embossed paper 1 is coated with paste in plural stripes (a) by a stripe-coating roller between paper sheets sent out from two paper rolls and formed into ruggedness by an embossing machine to form a strongly adhering state, coating paste in plural stripes (b) between a single-faced corrugated fiberboard 4 formed by a corrugation machine and the adhering paper 3 and producing the objective buffer paper by a joined paper roll in the method for producing the buffer paper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a packaging sheet having a buffer function.

[0002]

2. Description of the Related Art A conventional packaging sheet having a cushioning function has been made of a rigid artificial foam resin.

[0003]

[0007] Artificial resin products have problems such as emission of toxic gases during production and incineration. An object of the present invention is to solve the problems of the prior art by using recycled paper that does not emit toxic gas for production or incineration as a material.

[0004]

An infinite number of pressing portions are formed by passing a plurality of flat papers through an embossing machine in a state where a plurality of flat papers are stacked. It becomes more flexible, and the cushioning is further increased by crimping paper in one step.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 which is a perspective view partially showing buffer paper, embossing is performed in a state where at least two flat papers are stacked, and this embossing is a roller having countless irregularities. This is a conventional technique in which countless pressing portions 2 are formed by passing a flat paper between them, and a single embossed paper 1 formed by embossing exhibits flexibility and cushioning due to the unevenness. . However, only the embossed paper 1 alone has a limited buffering capacity due to the thickness, and
If a single piece of paper is made thicker, it becomes harder, and conversely, the cushioning property is impaired. Therefore, if embossing is performed in a state where a plurality of flat papers are stacked, the embossed paper 1 is coalesced by the innumerable pressing portions 2 to form the adhesive paper 3, and the adhesive paper 3 is rich in cushioning property due to its thickness, Since the layers are bundled in a plurality of layers, the layers are misaligned with each other, so that they are highly flexible. The buffer capacity is further increased, and the interleaving paper on the corrugated sheet is a method of applying glue in a direction perpendicular to the corrugation in a plurality of streaks and bonding and bonding the adhesive paper 3 and the single step 4. Although it is desirable to perform crimping paper, only the adhesion paper 3 may be used.

In FIG. 2, which is a left side view showing the manufacturing apparatus, the adhesion paper 3 is formed in a plurality of stripes by a stripe applying roller 6 between flat papers fed from at least two paper rolls 5. After applying the glue, the adhesive is firmly formed by passing between the rollers having countless protrusions of the embossing machine 7,
At the same time as the embossed paper 1 is formed, the embossed papers 1 are bonded to each other to form a bonding paper 3. The bonding of the bonding paper 3 is preferably performed by applying an adhesive. You do not need to use any
The adhesion can be achieved only by forming the pressurized portion 2 shown in the above, and the production method of the single step 4 is performed by using the stepping machine 8 of the prior art, and the b-stripe applying roller is used between the adhesion paper 3 and the single step 4. After glue is applied in a streak shape at 9 and stacked, it is passed between slip-off rollers 10 to be interleaved to complete the manufacture, and the shape of the streak applying roller is appropriately adjusted on the side surface of the columnar roller. The glue is applied in a streak form by attaching the rail and applying glue to this protruding rail. This streak application is performed by using a roller, squeezing from a thin nozzle using a welding material, commonly known as hot melt. It may be.

[0007]

As described above, since recycled paper is used, there is no problem such as emission of toxic gas during production or incineration, and the embossing machine forms a plurality of pressurized parts so that the embossed papers adhere to each other to reduce the buffering property. In addition, since the embossed paper has a multi-layer structure, the gap between the layers is shifted, so that the flexibility is not impaired even if the thickness is increased.
