Problems solved by technology

Biodegradation is achieved by adding modified starch, but it has a certain impact on product function and appearance, and some products are difficult to decompose eventually
Oxidative degradation occurs under aerobic conditions, but the additives are metal salts that pollute the soil. The most important thing is that the above degradations have a certain period, and there are strict requirements on the service life of the product. The waste in the production process cannot be recycled, and it cannot be widely promoted.

Abstract

The invention relates to a low-gloss anaerobic biodegradable biaxially oriented polypropylene film and a manufacturing method thereof, and belongs to the technical field of polypropylene film processing. The low-gloss anaerobic biodegradable biaxially oriented polypropylene film comprises an upper surface layer, a core layer and a lower surface layer, wherein the upper surface layer is prepared from the following raw materials in percentage by weight: 96.5-98% of polypropylene, 1.5-2.5% of an anti-sticking agent and 0.5-1.0% of an anaerobic biodegradation auxiliary chemical; the core layer isprepared from the following raw materials in percentage by weight: 93-97.5% of homo-polypropylene, 1.0-3.0% of an antistatic agent, 1.0-3.0% of a slipping agent and 0.5-1.0% of an anaerobic biodegradable auxiliary chemical; and the lower surface layer is prepared from the following raw materials in percentage by weight: 99.0-99.5% of a matte material and 0.5-1.0% of an anaerobic biodegradation auxiliary chemical. The film prepared by adopting the method does not change the function and appearance of the existing BOPP, and the decomposition products are water, carbon dioxide, methane and humusand do not cause any harm to the environment.

Description

technical field [0001] The invention relates to a low-gloss anaerobic biodegradable biaxially stretched polypropylene film and a manufacturing method thereof, belonging to the technical field of biaxially stretched polypropylene film processing. Background technique [0002] There are generally four types of existing plastic waste disposal methods: traditional landfill, incineration, recycling, and composting. Studies have confirmed that it takes more than 400 years for plastics to slowly decompose, so traditional burial and composting cannot fundamentally solve environmental pollution. Incineration of waste plastics will produce a large amount of carbon dioxide and toxic gases, which will aggravate environmental pollution and the greenhouse effect. More importantly, the above processing methods are limited to the situation where waste plastics are collected. As an excellent packaging material, biaxially oriented polypropylene film (BOPP film) is widely used in the packagi...
