Abstract

The utility model discloses a writing paper comprising a base paper layer and a rewritable material layer coated on the base paper layer, wherein the rewritable material layer of the writing paper makes the writing mark can't penetrate, thereby the writing mark can be erased and capable of rewriting. The utility model has the beneficial effects of saving paper resource, easy to use and low cost, thereby effectively solves the problem that the traditional writing paper can only be written once and causes waste.

Description

Writing paper

Technical field

The utility model relates to a kind of stationery paper, relates in particular to a kind of erasable writing paper that repeats.

Background technology

In routine work study, writing paper is our essential items, for example, is used for when whatman, foul papers etc.But traditional writing paper all is disposable, and the ink marks of writing on writing paper can not be wiped, and promptly uses once and just can not write once more later, must cause the waste of paper.Again because the main material of manufacturing writing paper is a timber, and the consumption of writing paper is extremely huge, so just seriously consumed the forest natural resources, thereby caused Ecological environment worsening indirectly, Fei Qi paper has too much had a strong impact on our living environment simultaneously, has also increased the paper resource and has reclaimed spent cost.

Summary of the invention

Based on the deficiencies in the prior art, the purpose of this utility model is to provide a kind of erasable writing paper that repeats.

In order to achieve the above object, a kind of writing paper of providing of the utility model includes base paper layer and covers erasable material layer on this base paper layer.

As an embodiment of the present utility model, described erasable material layer is the waxed paper substrates layer.

As another embodiment of the present utility model, described erasable material layer is the oilpaper material layer.

As an embodiment more of the present utility model, described erasable material layer is the plastic material layer.

The writing paper that the utility model provides compared with prior art, have and can repeat erasable erasable material layer, writing implement is write on erasable material layer, and erasable material layer can not infiltrate written trace, so written trace can be wiped, for writing once more next time.Palingraphia be can supply so the present invention writes paper, paper resource, easy to use, beneficial effect that cost is low saved thereby have.

In order to describe technology contents of the present utility model, structural feature, the purpose that realizes and effect in detail, further illustrate writing paper of the present utility model below in conjunction with the drawings and the specific embodiments.

Description of drawings

The cross sectional representation of one embodiment of Fig. 1 the utility model writing paper.

The cross sectional representation of another embodiment of Fig. 2 the utility model writing paper.

The specific embodiment

With reference now to accompanying drawing, embodiment of the present utility model is described, similar Reference numeral is represented similar elements in the accompanying drawing, writing paper of the present utility model includes base paper layer 1 and erasable material layer 2 as shown in Figure 1, erasable material layer 2 cover base paper layer 1 above.This erasable material layer 2 is integrated with base paper layer 1, erasable material layer 2 is to pass through the waxed paper substrates layer that forms after the ceroplastic, because the waxed paper substrates layer does not seep water, written trace only rests on the surface of this wax waxed paper substrates layer, can not be penetrated in the base paper layer 1 and go, realize the function of Palingraphia so can easily written trace be wiped.Described writing paper can also be as shown in Figure 2 simultaneously at the erasable material layer 2 that was coated with on the two sides of base paper layer after passing through ceroplastic,, the two sides of described like this writing paper can be repeated erasable.

Certainly described erasable material layer 2 can be independent moulding, and this erasable material layer 2 is to pass through the waxed paper substrates layer that forms after the ceroplastic, and this waxed paper substrates layer and base paper layer 1 are bonded together by press mold technology.

Described erasable material layer 2 can be to pass through the oilpaper paper wood bed of material that forms after the oily technology, erasable material layer 2 can also be to pass through to mould the plastic material layer that forms after the technology, base paper layer 1 can be selected differing texture as the case may be, the different-thickness paper stock, above-mentioned situation those of ordinary skill in the art can realize according to present embodiment easily, and is just burdensome no longer one by one here.

Above disclosed only is the preferred embodiment of a kind of writing paper of the utility model, certainly can not limit the interest field of the utility model with this, therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.

Claims (4)

1. a writing paper has base paper layer, it is characterized in that: also be coated with the erasable material layer of one deck on this base paper layer.
