Problems solved by technology

The matting layer raw materials in the matting film prepared by this method are only extruded and mixed once in the whole process, and there may be problems of uneven mixing and dispersion of polyethylene and polypropylene in the formula, resulting in poor matting effect
In addition, even if uniformly mixed matting raw materials are used, in addition to limiting the types and ratios of polyethylene and polypropylene, additives are also required to optimize their formulations, otherwise the following problems may occur: 1) The composition of matting materials The film property is not good, which affects the film-forming property of the PE base film, and is easy to cause film rupture; 2) The matting effect is not good enough, the haze is low, the gloss is high, or the matting effect is uneven, and there are differences between the middle and both sides of the film; 3 ) during the production of matting film, the mold head is seriously precipitated, and it needs to be shut down continuously for cleaning, the production cycle is short, the production efficiency is low, and the production cost is high

Description

technical field [0001] The invention belongs to the field of biaxially stretched polyethylene matting film, and in particular relates to a matting material for a BOPE matting film, a preparation method thereof and a BOPE matting film. Background technique [0002] Biaxially oriented polyethylene film, referred to as BOPE film, is obtained by synchronous or asynchronous stretching of polyethylene in the longitudinal and transverse directions. After stretching, the molecular chains and lamellae of polyethylene are highly oriented in two directions, and the optical and mechanical properties of the film are greatly improved. Compared with traditional blown and cast polyethylene films, BOPE film has a "thinning" effect, that is, it can use less packaging materials to achieve the same mechanical properties as traditional polyethylene (PE) films. Moreover, the development of BOPE can promote the development of PE single-material composite structure packaging solutions, which is co...
