Abstract

The invention relates to a BOPP film with low carbon dioxide emission and a preparation method thereof. The BOPP film comprises an upper surface layer, a core layer and a lower surface layer which are sequentially arranged, and the upper surface layer and the lower surface layer comprise the following components in parts by weight: 91-98 parts of homo-polypropylene, 1-5 parts of an anti-blocking agent and 1-4 parts of a carbon dioxide reducing agent master batch; the core layer comprises the following components in parts by weight: 90-98 parts of homo-polypropylene, 0.5-3 parts of an antistatic agent, 0.5-3 parts of a slip agent and 1-4 parts of a carbon dioxide reducing agent master batch; the carbon dioxide reducing agent in the carbon dioxide reducing agent master batch is a nano-scale carbonization catalyst liposome, and the nano-scale carbonization catalyst liposome is a spherical carrier preparation formed by encapsulating a carbonization catalyst in a single-layer phospholipid capsule. According to the BOPP film, on the basis that the original physical performance is not reduced and the good appearance is kept, carbon dioxide emission can be reduced when the BOPP film is used for waste incineration in subsequent treatment, and the preparation method does not need special production equipment and is easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of films, and in particular relates to a BOPP film with low carbon dioxide emission and a preparation method thereof. Background technique [0002] Biaxially oriented polypropylene film (BOPP for short) is a very important flexible plastic packaging material, which has the advantages of low price, light weight, transparency, non-toxicity, moisture resistance, low air permeability and high mechanical strength. BOPP film is widely used in packaging , printing and other industries. [0003] How to deal with BOPP film after use has attracted widespread attention. The follow-up treatment is mainly divided into the following aspects: part of recycling, part of landfill as urban waste, and a considerable part of waste incineration for power generation, while BOPP film incineration A large amount of carbon dioxide and water are produced, which in turn brings environmental pollution and ecological damage. Therefore...
