Problems solved by technology

[0007] The problem to be solved by the present invention is that the production process of PET reflective paper currently on the market is strict, the production line investment cost is very high, and the product thickness is limited at the same time. When manufacturing large-sized products, the stiffness is not enough, it is easy to deform, and it is not resistant to folding. The problem of folding is easy to occur, and a reflective paper with low production cost, good product stiffness and folding resistance is suitable for large-scale reflective products

Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0020] like figure 1 As shown, a reflective paper includes an intermediate layer 1 and a reflective layer 2. The intermediate layer 1 is a two-layer unfoamed biaxially stretched transparent PET film. The unfoamed PET film has a high density and sufficient stiffness. , while resistant to bending, the thickness of the PET film is 0.2mm, which has suitable stiffness and bending resistance; the reflective layer 2 is a foamed biaxially stretched PP film, and the thickness of the PP film is 0.1mm. At the same time, the thinner PP film is not easy to produce creases when the middle layer is attached to the reflective paper. The reflective layer 2 is respectively ...

Abstract

The invention discloses reflective paper. The reflective paper comprises a middle layer and reflective layers, wherein the middle layer comprises at least one layer of unfoamed bidirectionally-stretched PET (polyethylene terephthalate) thin film; the reflective layers are foamed bidirectionally-stretched PP (polypropylene) thin films; the reflective layers are glued to the two sides of the middle layer by compound glue respectively; the PET thin film is made of a transparent material; the thickness of the PET thin film is 0.1-0.3mm; the middle layer is a single-layer PET thin film or is compounded by multiple layers of PET thin films; the thickness of the PP thin film is 0.065-0.17mm. The reflective paper solves the problems that the PET reflective paper in the current market is strict in production process, very high in production line investment cost, limited in product thickness, as well as insufficient in stiffness, easy to deform, low in folding resistance and easy to generate folds when a large-sized product is manufactured.

Description

technical field [0001] The invention relates to the field of reflective film materials, in particular to a new three-in-one reflective paper. Background technique [0002] The reflective paper in this article is a film material used in backlight modules and flat-panel lighting products to improve the brightness of the product. It is also called reflective film on the market. It looks like paper. In this article, it is collectively called reflective paper. [0003] At present, the mainstream reflective paper on the market is mainly made of PET as the raw material and added with various fillers as the formula, and is produced by imported PET film biaxial stretching equipment. It is usually called PET reflective paper (film), and has the following disadvantages: [0004] (1) The input cost of the production line is very high, the cost of raw material formula and manufacturing cost are high, but the input cost, raw material cost and manufacturing cost of the composite reflective...
