Abstract

The invention discloses a book wrapping film and a machining technique thereof. The book wrapping film comprises bottom paper. A bonding layer is arranged on the bottom paper. A wrapping layer is arranged on the bonding layer. Openings are formed in the midpoints of the two long edges of the book wrapping film. The machining technique comprises the following steps of (1) gluing combining, (2) oiled paper combining, (3) cutting, (4) edge punching and (5) packaging. According to the book wrapping film, by bonding a PVC film to the bottom paper, the book wrapping film is simple in structure and low in cost. In addition, through the design of edge folding, using is convenient. Furthermore, a pattern layer can be additionally arranged so that the book wrapping film can be attractive and fashionable.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to a book wrapping film and its processing technology. Background technique [0002] The book wrapping film can protect the books and reduce the impact of damage such as abrasion or folding of the books. At present, common book wrapping materials include hard paper and plastic. This kind of book wrapping film is relatively hard and inconvenient to use. Some of them require further processing such as cutting after the user buys it back; Some book wrapping films have complex functions, are not practical, and are expensive, which is not cost-effective. Contents of the invention [0003] In order to solve the problems of inconvenient use and high cost of the existing book wrapping film, the present invention provides a book wrapping film with simple structure, convenient use and low cost. [0004] In order to achieve the above object, the technical solution provided by the...
