Description

本实用新型涉及一种文化用品,特别是一种纸质白板。
传统使用的可擦除书写方法一是用粉笔在黑板上书写,擦除时粉尘飞扬;第二种是用铅笔在纸上书写。这二种方法都会留下痕迹。为了克服这个缺陷,人们研制出一些可在非渗透性和非吸收性面板上书写的书写液,它易写易擦,不留痕迹,但尚无用于该书写的专用板面。
本实用于新型的目的是提供一种可供书写液书写的非吸收性和非渗透性板面,并且具有价廉和使用方便的特点。
本实用新型是在纸的表面涂覆一层塑料薄膜。
本实用新型可以代替木质板,并制成练习本。用书写液书写后,易擦,且不留任何痕迹。它使用方便,经济实惠,并且可以折叠。
附图为本实用新型结构示意图。
在纸1的表面除覆一层塑料薄膜2,形成一个非渗透性面。上述塑料薄膜可采用聚乙烯材料。
