Abstract

The present invention discloses a preparation method for an APET film with aroma. The preparation comprises: a) selecting materials and mixing the materials, b) carrying out a drying treatment, c) carrying out extruding plasticizing, d) carrying out three-roller calendering, and e) carrying out a film post-treatment. According to the present invention, the preparation method for the APET film with aroma is disclosed, the preparation method has characteristics of reasonable and compact process arrangement, scientific implementation process and moderate cost, and the prepared APET film has the excellent and stable use performance and can emit the aroma in a lasting manner so as to effectively enrich the film functionality, such that the APET film is more suitable for the outer package of various types of fashion products.

Description

technical field [0001] The invention relates to a method for preparing an APET film, in particular to a method for preparing an APET film with fragrance, and belongs to the technical field of APET products. Background technique [0002] APET film is a polyester sheet of plastic-absorbing material, also known as polyester hard tape. It belongs to thermoplastic environmental protection plastic products. Its side materials and waste products can be recycled. Degradable plastic. When packaged products made of this material are discarded, they end up as water and carbon dioxide. APET environmental protection film is widely used in the packaging of cosmetics, food, electronics, toys, printing and other industries, such as various high-end blister packaging, folding boxes, rubber tubes, windows, etc. At this stage, China already has relatively mature APET production technology, and its price is far lower than that of PETG sheet. [0003] APET film has excellent and stable physic...
