BOPP (biaxially-oriented polypropylene) aluminum-plated base film for packaging

Abstract

The invention relates to the technical field of packaging base films, and discloses a BOPP (biaxially-oriented polypropylene) aluminum-plated base film for packaging. The BOPP aluminum-plated base film is sequentially composed of a heat sealing layer, a core layer and a base film layer, and the heat sealing layer is prepared from the following raw materials in parts by weight: 3-4 parts of an organic anti-adhesive agent, 3-5 parts of a maleic anhydride grafted modifier and 95-100 parts of a heat sealing material; the core layer is prepared from the following raw materials in parts by weight: 1 to 2 parts of antistatic material and 99 to 102 parts of homo-polypropylene; and the base film layer is a BOPP (biaxially-oriented polypropylene) aluminum-plated base film layer and comprises the following raw materials in parts by weight: 1-5 parts of ethylene-octylene copolymer and 100 parts of PP (polypropylene) raw material. The heat sealing layer is packaged on the outermost layer of the BOPP base film layer, so that external heat can be isolated on the outer side of the BOPP base film layer by virtue of the strong heat insulation performance of a heat sealing layer material, and the interior of the BOPP base film layer is ensured to be in a long-term suitable temperature, so that an article packaged in the BOPP base film layer is not easily damaged by the heat, and the effect that the BOPP base film can preserve articles for a long time is achieved.

Description

technical field [0001] The invention relates to the technical field of packaging base films, in particular to a BOPP aluminized base film for packaging. Background technique [0002] BOPP base film is biaxially stretched polypropylene base film. The production of BOPP base film is to first make the melt of high molecular polypropylene into a sheet or thick film through a narrow and long die, and then stretch the thick film transversely and longitudinally. , made basement film by corona water bath treatment. [0003] The current BOPP base film is fragile. After packaging, it is difficult to store for a long time and is easily damaged. Moreover, the BOPP base film does not have the performance of heat insulation. When the external temperature changes, it is difficult to protect the inner layer. protection, so we propose a BOPP aluminized base film for packaging. Contents of the invention [0004] In order to achieve the above object, the present invention provides the foll...
