Abstract

The invention belongs to the technical field of packaging materials, and particularly relates to a PE vacuum aluminized composite film and a preparation method thereof. The PE composite film comprisesa PE composite base film and an aluminized film connected to one side of the PE composite base film, and the PE composite base film comprises low-density polyethylene, metallocene polyethylene, surface adhesive resin, linear polyethylene, an antioxidant, a heat stabilizer, an ultraviolet blocking agent and an anti-blocking agent. The surface adhesive resin is added into the PE composite base film, so the adhesive force of the PE composite base film to the aluminized film is greatly improved, and the problem that the aluminized film falls off is solved; and the anti-blocking agent is added into the PE composite base film, so a prepared packaging bag is not prone to adhesion and has good opening properties.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a PE vacuum aluminized composite film and a preparation method thereof. Background technique [0002] With the continuous development of my country's economy, the demand for PE barrier composite films in the packaging industry is increasing day by day, and the scope of application is also expanding. Due to the poor oxygen and water vapor barrier ability of PE, and the excellent oxygen and water vapor barrier ability of aluminum foil, but the two Combination can only be combined, and the cutting performance of aluminum foil is poor, and the high cost is not conducive to promotion and application. PE vacuum aluminized composite film not only has very good oxygen and water vapor barrier ability, but also has good performance and low cost. It has good comprehensive performance in terms of mechanical properties and appearance novelty, and is easy to promote and u...
