Abstract

The utility model discloses repeatable writing paper which comprises a paper base with front and back writing surfaces, and the roughness of the writing surfaces of the paper base is 5.9-8.7 mum; and a biaxially-oriented polypropylene (BOPP) film is compounded outside the paper base. The thickness of the BOPP film is 15-20 pm. The utility model has the advantages that the writing surfaces of the paper base are rough surfaces, the BOPP film can be tightly combined with the paper base when the BOPP film is compounded on the paper base, and the writing paper has the functions of waterproofness and wear resistance. Because the surfaces of the paper base are rough, the surfaces of the writing paper after compounding are also relatively rough, the friction coefficient of the writing surfaces is great, ink from a writing pen is left in grooves during writing because the writing surfaces of the writing paper have raised grains, and the ink can be quickly air-dried in the grooves. The writing paper has clear and clean handwriting and smooth writing, and the problems of difficult combination of paper surfaces and ink and poor writing effect due to too ductile paper base are solved.

Description

The reusable manuscript paper of drilling

Technical field

The utility model relates to writing paper, especially relates to a kind of reusable manuscript paper of drilling.

Background technology

Along with the fast development of economic society, China has become world papermaking big country, and 2000 to 2009, China's paper-making industry annual production rose to 8,640 ten thousand tons from 3,050 ten thousand tons.As student, clerical workforce and technical staff write in a large number usefulness drill manuscript paper since use amount huge, become one of consumptive material main in the stationery class.Because the disposable operating characteristic that existing writing paper is had; Write with drilling manuscript paper and can only use once and promptly go out of use; The traditional manuscript paper of drilling that can only write is once reused; Protecting the limited forest reserves of our earth, is that the knowledgeable people of paper industry needs the direction of effort for it.

Summary of the invention

The reusable manuscript paper of drilling that the purpose of the utility model is to provide a kind of and economizes on resources, protects environment, cuts the waste.

For realizing above-mentioned purpose, the utility model can be taked following technical proposals:

The described reusable manuscript paper of drilling of the utility model comprises the paper substrate that has positive and negative writing surface, and the writing surface roughness of said paper substrate is 5.9-8.7 um; Be compounded with Biaxially oriented polypropylene (BOPP) film in the outside of said paper substrate.

The thickness of described bidirectional stretching polypropylene film is 15-20pm.

The advantage of the utility model is that the writing surface of paper substrate is a matsurface, when the BOPP film being adopted hot stamping or crossing and mould after technology is compounded in it on paper substrate, the BOPP film can be coated on paper substrate wherein closely, makes to drill manuscript paper and had waterproof, wear-resisting function; Because the rough surface of paper substrate is uneven, the also coarse relatively injustice in the surface of drilling manuscript paper after compound, the coefficient of friction of writing surface is bigger; When writing; The ink of writing pen can remain in the groove owing to the asperities that writing surface had of drilling manuscript paper makes ink, will soon be in groove by air-dry, and writing is clear, clean; Fluent writing, solved paper substrate since cross mould make paper and ink be difficult to combine, problem that writing effect is not good; After positive and negative writing surface finishes, can this be drilled the manuscript paper water and rinse well, reuse once more.This is drilled manuscript paper and is particularly suitable for repeated uses such as student's calculation, clerical workforce's blotter.Not only can also can practice thrift the manuscript paper investment of family and unit for environmental protection contributes.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the enlarged drawing of Figure 1A portion.

The specific embodiment

Like Fig. 1, shown in 2, the described reusable manuscript paper of drilling of the utility model comprises the paper substrate 1 that has positive and negative writing surface, and the positive and negative writing surface roughness of paper substrate 1 is 5.9-8.7 um (roughly similar newspaper surface gets final product); Mould technology in the outside of paper substrate 1 through hot stamping or mistake and be compounded with thickness 15-20pm Biaxially oriented polypropylene (BOPP) film 2; Film 2 can paper substrate 1 is complete coating wherein; Finished product drills that manuscript paper is light, wear-resisting, smooth, waterproof; Advantage with repeated use, fluent writing on the basis of satisfying the water resistance index, can guarantee that again writing mask has stronger hydrophilicity.

Because what laminated film adopted is the BOPP pre-coating film of thickness 15-20pm; Soft, nontoxic and transparency is high; After compound drill that manuscript paper can curl arbitrarily and can delamination, can write with ball pen, water-color paintbrush or pencil, satisfied large, medium and small student and clerical workforce's user demand.
