The invention discloses a plastic film with holes, which comprises a film base (1) and holes (2), the holes (2) are evenly distributed on the film base (1), and the holes (2) are adjacent to each other in the horizontal and vertical directions. ) between 5-10mm. The hole (2) is a round hole or a square hole. The beneficial effects of the invention are: the perforated plastic film involved in the invention has a simple structure, relatively low cost and is practical. Compared with plastic film without holes, it saves raw materials, and no air bubbles appear during use.
Description
technical field [0001] The invention relates to a plastic film, in particular to a plastic film with holes. Background technique [0002] At present, the cover of the book packaging of the known technology is to use a plastic film to push and press the cover through heating to achieve a plastic seal on the cover to keep it flat and clean. However, because the film of the prior art is non-porous, it will produce Air bubbles, frequent adjustments to equipment, affect work efficiency, and at the same time, calculations from the perspective of raw materials have not achieved the consequences of saving resources. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the invention provides a plastic film arranged in a rectangle, which can make the packaging more flat and save raw materials at the same time. [0004] The technical solution of the present invention is achieved in the following way: a plastic film with holes, comprising a film ...
