New description: [New technical field] This creation is related to packaging materials, especially a multi-layer spacer. [Prior Art] 5 According to the wide range of use of spacers, for example, when a plurality of glass substrates are packaged in a package, the principle is mainly to place a plurality of spacers on each of the glass substrates. Each of the glass substrates is partitioned by each of the spacers to achieve the purpose of protecting the glass substrate. The general spacer is made of a plastic foamed material, and the foaming ratio of the foamed material must be increased if a better buffering capacity is required. However, the spacer with high expansion ratio is soft. If it is applied in an upright storage, the soft spacer is difficult to stand, and it may fall off during use. On the contrary, if the hardness of the spacer is high, its application In the vertical storage is relatively no problem, but the harder spacer is made of a foaming material with a low foaming ratio of 15, so the buffering capacity provided is a weaker problem. [New content] Shiben creation The main purpose of the invention is to provide a multi-layer spacer which has better buffering capacity and higher rigidity. The scoop 4 is for the purpose of creation. The multi-layer spacer soil & (three) and the two buffer layer provided by the present invention are located on the substrate. The two sides of the layer, wherein the base layer is higher in rigidity than the two buffer layers. /, 20 M310195 [Embodiment] In order to explain in detail the structure and features of the present invention, the following preferred embodiments are described with reference to the drawings. As shown in the first figure, the multilayer spacer 1 provided by the present invention is composed of a base layer 12 and two buffer layers 14. As shown in the second figure, The spacer 10 has a plurality of perforations 16 and the edges have a plurality of recesses 18 which are characteristic of the object corresponding to the desired spacing. In this embodiment: the spacers are used for spacing the liquid crystal substrate (not shown). The perforations 16 and the recesses 18 疋 correspond to the integrated circuit on the liquid crystal substrate (1), and the electronic components such as the H-transformed H, so that the above good components are not subject to the 1 = line corresponding to the liquid crystal substrate of different specifications, a spacer The shape of 20 can be made as shown in the third figure. *... The base layer I2 is a plastic sheet with a thickness of 〇·8 丽~3. The base layer 12 can be PET (p〇lyethylene such as 叩 she also (6),

The base layer 12 mainly provides the spacer 1 () with a certain rigidity and has a function of dispersing pressure. As shown in the fourth figure, the two buffer layers 14 are attached to one side of the base layer 2〇12. The two buffer layers are multi-porous structures obtained by foaming materials such as ρρ, ρΕ, ρ§ ρυ, ρν(^(ρ〇ΐρ^β chlonde), etc. The foaming ratio of the aforementioned foaming material can be 2倍〜5 () times, the preferred expansion ratio can be 5 l 30 乜 better expansion ratio can be 1 〜 ~ μ times. The two buffer layer 14 is mainly to provide elastic buffering ability. In some In a specific case, the two M310195 buffer layers 14 can be made of foaming materials of different expansion ratios or different materials to provide different buffering capacities. The fourth figure shows another type of spacer 30, which is mainly The configuration is the same as described above, except that a predetermined texture 534 is provided on the surface of the buffer layer 32, thereby reducing the effect of electrostatic adsorption. Thereby, the spacer provided by the present invention not only has a certain rigidity, so that it can be applied to it. In the upright storage condition, he also has considerable buffering capacity to protect stored items.
