Abstract

The utility model relates to a plastic book cover, which is used for packing the front cover of the book. The plastic book cover is suitable for books with any widths and thicknesses. The utility model is composed of two blocks of inner layer plastic film and a block of outer layer plastic film. The edges of the upper ends and the lower ends of the inner layer plastic film are connected with the edges of the upper end and the lower end of the outer layer plastic film, and the outer ends of the inner layer plastic film are not connected with the outer end of the outer layer plastic film.

Description

Plastic book cover

The utility model relates to a kind of plastic cover.

The plastic cover that existing bag books are used, form by inside and outside two layers of plastic thin films, skin is a block length square plastic film, internal layer is two block length square plastic films, and upper end, lower end and the outer end edges of two block length square plastic films of internal layer are joined with upper end, lower end and the outer end edges of outer field rectangle plastics film respectively.This plastic cover can only be packed the cover of certain altitude, width and thickness, can not adapt to the variation of the thickness and the width of books.

The purpose of this utility model provides and a kind ofly can be applicable to any width and thickness and make things convenient for plastic cover.

Technical solution of the present utility model is made up of outer layer plastic film of two internal layers, the upper end of internal layer (1), edge, lower end (2), with outer field upper end (1), lower end (2) side edge, it is characterized in that respectively: the outer end of internal layer (3) do not join with outer field outer end (4).

The thickness of plastic sheeting greater than 0.05 millimeter less than 0.12 millimeter.

Plastic sheeting preferably adopts the mach tubular plastic sheeting of blowing, implements the utility model with this tubular plastic sheeting, as long as select its girth to be suitable for the high size of book, opens the twice seam along the upper and lower side direction in the middle part of the layer within it and gets final product.

Advantages such as it is simple to the utlity model has processing, easy to use.

Accompanying drawing is a schematic diagram of the present utility model.

Embodiment:

Adopt the tubular plastic sheeting, its thickness in monolayer is 0.08 millimeter, and 370 millimeters of girths are respectively opened a seam apart from 145 millimeters places, two outer ends along the upper and lower side direction at internal layer.The length of seam is 185 millimeters, the cover page of high 184 millimeters, wide 130 millimeters of book, thick book less than 50 millimeters is inserted respectively in the twice seam of being opened, cover page is placed between the ectonexine, that a part of plastic sheeting that the cover page end is grown folds to the inside, is stained with adhesive sticker to get final product.Tubular plastic sheeting recited above, its length are 360 millimeters.

Claims

1, a kind of plastic cover, form by two internal layers, an outer layer plastic film, the upper end of internal layer [1], edge, lower end [2] with outer field upper end [1], lower end [2] side edge, is characterized in that respectively: the outer end of internal layer [3] do not join with outer field outer end [4].

2, plastic cover according to claim 1 is characterized in that: the thickness of described plastic sheeting is greater than 0.05 millimeter, less than 0.12 millimeter.
