Embodiment 1

[0023] Preparation of the film: mix the raw materials for the film in proportion and then make the film by blowing film, pressing the film and trimming the edges; among them, the composition of BOPP is: polypropylene (PP J340) 82wt%, EPDM 10wt%, trimethoxysilane 3wt %, antioxidant 10102wt%, heat stabilizer dibutyltin dilaurate 3wt%. Among them, the thickness of BOPP film is 25 microns and 20 microns.

[0024] Composite film formation: (1) Dry lamination: BOPP25 is coated with adhesive under the action of pressure rollers, and then forms composite film 1 with AL7 under the action of pressure rollers, and the composite film 1 continues to be pressed under the action of pressure rollers After the adhesive is applied, the composite film 2 is formed with PET12 under the action of the pressure roller. After the composite film 2 is coated with the adhesive under the action of the pressure roller, it is formed with BOPP20 under the action of the pressure roller. The composite film 3 ...

Abstract

The invention belongs to the field of packaging films, and particularly relates to a high-strength breaking-resistant glass cement packaging film and a preparation method thereof. A structure of the packaging film is a composite structure comprising a single-side heat seal BOPP25 / AL7 / PET12 / single sided hot seal BOPP20, and a dry-type compounding process is adopted to prepare the packaging film. The BOPP film is prepared by selecting a polypropylene material with a particular melt flow rate and adding pressure-resistant particles, so that the pressure resistant strength and elongation at break of the packaging film can be improved; and the packaging film has good hot sealing strength and high tensile strength.

Description

technical field [0001] The invention relates to the field of packaging films, in particular to a high-strength anti-break glass glue packaging film and a preparation method thereof. Background technique [0002] As a key bonding and sealing material for glass curtain walls, aluminum curtain walls, and stone curtain walls, glass glue has long relied on imports in my country. The production and application of glass glue abroad has reached a relatively high level, and the global market is basically monopolized by several major companies such as Dow Corning, GE, Wacker, RP, and Shin-Etsu in the United States. Dow Corning's products occupy the main domestic market. The development of glass glue in my country began in the 1960s, but the progress was very slow, and no industrialized products were put on the market until the 1980s. Since the 1990s, the speed of development has accelerated significantly, and domestic products of glass glue have occupied more than 50% of the domestic...
