Abstract
The utility model discloses a rewritable paper product, belonges to a paper product for writing, drawing or spraying (characters) by use of the matching ink (printing ink and powered ink), and particularly relates to an impermeable biodegradable rewritable paper product made from a chemical film for printed products and paper. The rewritable paper product comprises a paper base layer (using a semi-finished product with printed content such as offset paper, coated paper, kraft paper, card paper and the like or unprinted raw paper); and a layer of impermeable biodegradable chemical film for printed matter which can be bonded on the paper base layer is arranged on the front and back sides of the paper base layer respectively. Due to the impermeable chemical film, the content written, drawn or sprayed (characters) by use of the matching ink (printing ink and powdered ink) on the chemical film can be easily wiped by a water-containing tool (towel and the like), thus the recorded content can be modified at will, the rewritable paper product can be repeatedly used within 10 years, the practicability is improved, and the waste of raw material is greatly reduced; and moreover, since the chemical film can be biologically degraded, little environmental pollution is caused.
Description
Technical field
The utility model belong to a kind of use matching ink (printing ink, ink powder) write or draw, the paper products of spray figure (word), be specifically related to a kind ofly not seep water, can biodegradable printed matter with the erasable paper products of chemical films with the paper manufacturing.
Background technology
Various erasable paper products in the market, employed film, be can natural degradation with can not natural degradation or be difficult to the chemical films of degraded, although the former can play saving, energy-conservation effect in conserves paper, but cost is relatively high at present, although the latter also can play saving, energy-conservation effect in conserves paper, the recycling difficulty is large, also has certain problem of environmental pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of biodegradable erasable paper products.
The technical solution of the utility model is as follows: a kind of can be repeatedly erasable paper products, comprise a papery basic unit, the tow sides of papery basic unit all have one deck be bonded in not seeping water in the papery basic unit, can biodegradable printed matter chemical films.
Aforesaid can be repeatedly erasable paper products, wherein, described chemical films for do not seep water, can biodegradable printed matter chemical films.
Aforesaid can be repeatedly erasable paper products, wherein, the body paper of described papery basic unit for using offset paper, art paper, brown paper, paperboard etc. to print the semi-finished product of content or not have to print.
Aforesaid can be repeatedly erasable paper products, wherein, the thickness of described chemical films is 15-150 micron (um).
Since the utility model paper products the tow sides of papery basic unit bonding respectively one deck do not seep water, can biodegradable printed matter chemical films, can be with moisture instrument (towel etc.) wiped clean easily in the content of the supporting ink (printing ink, ink powder) of this chemical films use; And because paper is two-sided overlay film, and the tension force of positive and negative is identical, long-term use is not yielding.This paper products not only can arbitrarily be revised the content that records after using supporting ink (printing ink, ink powder), can also be in 10 years Reusability, strengthened the practicality of paper products, saved ample resources, reduced waste.In addition, be the biodegradable chemical films of energy because of what use in the papery basic unit, can not cause secondary pollution to pollute to environment.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of the utility model paper products.
Among the figure 1, papery basic unit 2, do not seep water, can biodegradable printed matter chemical films
The specific embodiment
A kind of can be repeatedly erasable paper products comprise a papery basic unit 1, the tow sides of papery basic unit 1 all have one deck be bonded in not seeping water in the papery basic unit 1, can biodegradable printed matter with chemical films 2.This chemical films is firmly to be bonded in the papery basic unit 1 by the form that roll extrusion is heated.The thickness of this chemical films is 15-150 micron (μ m), all can select such as 15,18,25,28,35,150 microns (μ m) etc., this exemplifying embodiment is selected can the biodegradation chemical films thickness be 35 microns (μ m).Because bonding this chemical films in papery basic unit, after supporting ink (printing ink, ink powder) use, during such as need modification or update content, as long as with gently wiping of moisture instrument (towel etc.), just original ink marks can be removed, do not stay any ink marks, environmental protection and saving, easy to use.And same paper products can be in 10 years, hundreds of times of Reusability can be saved a large amount of papermaking materials, the energy and water, in addition, because of its use be biodegradable chemical films, after the chemical films in the papery basic unit has been degraded, can not cause secondary pollution to environment.
This erasable paper products, practicality is very strong, not only can be made into various children and write from memory the products such as basis, part teaching material with copybook, manuscript, exercise-book, word (short sentence etc.) with picture album, student, can also be made into the products such as various poster papers, price tag.
Claims (3)
