Zhenhai Refining & Chemical Co., Ltd. successfully researched and produced new polyethylene-plated aluminum-based products

China Petrochemical News Network reported on August 4, Zhenhai Refining & Chemical's polyethylene plant successfully produced 140 tons of special materials for polyethylene aluminized substrate film
.
The product has the characteristics of less precipitation, high transparency, and high tensile strength, and has good aluminum adhesion properties.

In the domestic market, most high-barrier packaging films are made of polypropylene or polyethylene and high-barrier materials, which are relatively expensive
.
High barrier materials such as ethylene-vinyl alcohol copolymer or nylon are not recyclable, and the packaging film cannot be reused after it is discarded

In May of last year, Zhenhai Refining & Chemical Co.
, Ltd.
trial-produced a special material for polyethylene aluminized base film for the first time.
After the trial, the manufacturer believed that the aluminum adhesion force could not fully meet the production needs and proposed improvement requirements

On August 3, Zhenhai Refining and Chemical Polyethylene Plant switched brands, technicians tracked the whole process, and maintained real-time communication with teams and quality inspections, which overcomes the difficulty of reverse melt finger control, density jamming, and reactor parameter adjustment during the process of brand cutting.
After waiting for difficulties, the production task was successfully completed
.
At present, the self-sold product has been contacted with the cooperative enterprise for trial
