Embodiment Construction

[0005] First, the rough surface of the paper is bonded to the bright surface of aluminum foil. The bonding material is low-density polyethylene particles LDPE (ICTA) produced by Beijing Yanshan Chemical Plant, with a basis weight of 13~14g / m 2 , The temperature is controlled between 315~340℃, and the compound speed is 50~60 m / min. Secondly, the requirements for the first coating on the aluminum surface: the aluminum surface coating is a matte film, the adhesive material is LDPE (ICTA) + AE (modified polyethylene particles produced by DuPont); the ratio is (80kg+20kg) , The film quantitative is 13~14g / m 2 , The temperature is controlled between 315~340℃, and the coating speed is 50~60 m / min. Finally, the second coating requirements: coating on the first coating surface (heat seal layer), the coating material is DuPont plastic particles 53007 or 20D745 + antistatic agent (produced by Shanghai Auxiliary Factory), with The ratio is (100kg+2kg), and the film quantitative is 15g / m 2 ±1g...

Abstract

The invention discloses the manufacturing technique of composite paper, comprising the following steps: a. the rough surface of paper and the bright surface of aluminum foil are glued by LDPE; b. drenching film on the surface of aluminium; c. the second drenching film, and adding antistatic agent into the drenching film material. The technology removes the package pollution from maize flour and possesses the high utilization value.

Description

Technical field [0001] The invention belongs to the technical field of packaging and printing, and in particular relates to a production process of bowl surface cover composite paper. Background technique [0002] The paper bowl surface cover composite paper currently on the market is electrostatically charged, which makes the printing and packaging operations prone to double / multiple adhesion problems. Corn flour used to reduce its adhesion will cause pollution to printing and packaging products. Summary of the invention [0003] The purpose of the present invention is to provide a production process for bowl surface cover composite paper that can effectively overcome the above-mentioned defects and prevent double-sheet / multiple-sheet adhesion problems during the packaging operation. The technical solution of the present invention is a production process of bowl surface cover composite paper, which is characterized in that: the process is carried out according to the following ...
