Abstract

The invention belongs to the technical field of composite aluminum-plated bags, and particularly relates to a production process of a solvent-free composite aluminum-plated bag, which comprises the following processing steps: (1) mounting a printing film and an aluminum-plated film to be compounded on a solvent-free compounding machine; (2) blending a solvent-free two-component polyurethane adhesive; (3) debugging; (4) compounding: unwinding the aluminum-plated film, and controlling the tension to be 0.6-0.8 N / cm in the unwinding process; conveying the aluminum-plated film and the printing film coated with an adhesive solution to a composite roller, compounding the printing film and the aluminum-plated film under the pressure of 0.18 mpa / cm < 2 > to 0.23 mpa / cm < 2 >, wherein it is guaranteed that the temperature is controlled to be 35 DEG C to 40 DEG C while compositing is conducted; (5) cooling; (6) coiling: coiling the cooled film material into a coil under the tension of 1 to 1.4 N / cm; (7) drying and solidifying. The solvent-free composite aluminum-plated bag is produced by using the means of the scheme, and the produced composite aluminum-plated bag can meet the requirements in the aspects of sealing performance, high temperature resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of composite aluminized bags, and in particular relates to a production process of a solvent-free composite aluminized bag. Background technique [0002] Aluminum-coated film is made by evaporating high-purity aluminum wire into a gaseous state at high temperature (1100-1200°C) through a vacuum aluminum-plating process, and then when the plastic film passes through a vacuum evaporation chamber, the gaseous aluminum molecules precipitate on the surface of the plastic film to form a bright Metallic color film is the main raw material for making composite aluminized bags. [0003] Composite aluminized bag refers to the bag made by compounding the printed film and the aluminized film. When preparing the aluminized bag, it is necessary to use glue to combine the two materials. Since the solvent-based glue has been developed very maturely, various performance indicators Both can better meet the production needs, ...
