VCI+ gas phase anti-rust film is a relatively good VCI+ gas phase anti-rust packaging material developed in recent years. It is an anti-corrosion packaging material formed by adding gas phase corrosion inhibitors to plastic films in a certain way. It is a special functional film.
The production and development history of VCI+ gas phase anti-rust film is later than that of gas phase anti-rust paper, but compared with VCI+ anti-rust paper, it can not only simplify the packaging process, but also has the advantages of transparency, thermoplasticity and airtightness. At the same time, it can be recycled and reused, saving resources and being very environmentally friendly. At present, as one of the main products of VCI+ gas phase anti-rust packaging materials, the research and application of VCI+ gas phase anti-rust film has received increasing attention, and the market share has increased year by year.
With the continuous development of corrosion inhibitor synthesis technology and plastic processing technology, VCI+gas phase anti-rust film has become a widely used VCI+gas phase anti-rust packaging material, which can meet the packaging of metal products of different specifications, ranging from mechanical parts of a few millimeters to entire aircraft. Applicable fields include: automotive industry, shipbuilding, aircraft field, machinery field, electrical appliances, electronics field, metallurgy field, hardware tools, weapons and equipment and other metal processing fields.
With the widespread application of VCI+gas phase anti-rust film products, customers in different fields have put forward more requirements on its appearance, smell, structure, strength, form of expression and other aspects. In order to cope with metal product packaging of different shapes, volumes and uses, VCI+VCI film products have developed from the original ordinary PE VCI film to fabric-reinforced VCI+VCI film with multi-layer structure, aluminum-plastic composite VCI+VCI film, VCI+VCI heat shrink film and VCI+VCI stretch film; from the initial simple film form to various forms such as flat bags, anti-rust covers and cushioning pads. With the improvement of people's awareness of environmental protection and health, customers pay more attention to the odor and toxicity of VCI+VCI film. Low-odor, nitrite-free and environmentally friendly VCI+VCI film products are increasingly favored by the market.
Through the analysis of customer market demand and the collection and research of products of major domestic and foreign manufacturers, VCI+VCI film products and technologies are currently developing in the following directions:
(1) Corrosion inhibitors for VCI+VCI films are developing in the direction of general, high-efficiency, non-toxic and environmentally friendly. Universal nitrite-free VCI+ gas phase anti-rust film products suitable for multi-metal anti-rust protection have attracted wide attention from customers.
(2) VCI+ gas phase anti-rust film products are developing towards the direction of diversified product structure, diversified forms, and diversified base resins. This is mainly reflected in the emergence of VCI+ gas phase anti-rust film products with multi-layer composite structures, different forms, and different materials. For example, fabric-reinforced VCI+ anti-rust film, aluminum-plastic composite VCI+ anti-rust film, VCI+ gas phase stretch anti-rust film, VCI+ gas phase anti-rust biodegradable film, and polyvinyl acetate VCI+ anti-rust film.
(3) Higher requirements are placed on the appearance and odor of VCI+ gas phase anti-rust film products. Low odor, good transparency, and beautiful VCI+ products are very popular with customers.
