Data book of FPP (foamed polypropylene) material as well as preparation method thereof

Abstract

The invention relates to a data book of an FPP (foamed polypropylene) material as well as a preparation method thereof. The data book comprises an outer plate of the FPP material, an inner page bag and a PP (polypropylene) base plate; the outer plate comprises a cover, a back cover and a backbone; the PP base plate comprises a stapling area and a fusion welding area; a bending line is arranged between the stapling area and the fusion welding area; the inner page bag is fixed in the fusion welding area through fusion welding; and the back cover of the outer plate and the stapling area of the PPbase plate are stapled and fixed. The PP base plate is utilized cleverly, rivets on the backbone in the prior art are transferred to the back cover, the position of the back cover is concealed, people are not easy to notice, and the rivets are not arranged on the backbone, so if products with back strip paper and a back strip bag exist, the back strip paper is more convenient to extract and put,the problem that the product is jacked by the rivets to be protruded is avoided, and the appearance level of the products and user experience are improved; in addition, the preparation process of thedata book is more stable and the quality of the products is more stable.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to an FPP material booklet and a preparation method thereof. Background technique [0002] PP refers to polypropylene material, FPP refers to expanded polypropylene, and FPP has a lighter unit volume, so it is more and more used in information books or file folders. The information book generally includes the outer panel and the inner page bag. The outer panel made of PP material can be welded with the inner page bag, so the back of the outer panel made of PP material has no rivets, and the outer panel made of FPP material cannot be welded with the inner page bag. Welding, this is caused by the characteristics of FPP material, so generally the inner page bag is fixed on the back by riveting, so it is inevitable to leave more than two rivets on the back, such as figure 1 with figure 2 As shown, these rivets affect the appearance of the product, reduce the user experience, ...

AI Technical Summary

Problems solved by technology

The information book generally includes the outer panel and the inner page bag. The outer panel made of PP material can be welded with the inner page bag, so the back of the outer panel made of PP material has no rivets, and the outer panel made of FPP material cannot be welded with the inner page bag. Welding, this is caused by the characteristics of FPP material, so generally the inner page bag is fixed on the back by riveting, so it is inevitable to leave more than two rivets on the back, such as figure 1 and figure 2 As shown, these rivets affect the appearance of the product, reduce the user experience, and are arranged together with the PP material booklet, which is ugly; and the position of the rivet will affect the assembly of the matching back bag, back paper, and back label. effect, needs to be improved
