What Should I Pay Attention to When Using VCI Film Packaging?

The anti-rust protection of metal parts can ensure the quality of the product in transportation. VCI stretch film does not contain nitrites, phosphates and amines, and complies with environmental protection standards such as the EU ROHS Directive and REACH regulations, but to give full play to the anti-rust effect, many important details need to be paid attention to in actual operation. Let's take a look together!

Introduction of VCI stretch film:

VCI stretch film is a plastic film that incorporates a gas phase rust inhibitor. After packaging, the rust inhibitor will slowly evaporate, forming a protective molecular film on the metal surface, which can effectively isolate moisture and oxygen and prevent corrosion. VCI stretch film usually has tensile properties, can directly wrap items, is easy to operate, and has a long anti-rust period.

VCI stretch film application:

This VCI stretch film is not only for a certain kind of metal, steel, iron, aluminum, aluminum alloy, copper, silicon steel, as well as phosphate sheet, galvanized sheet, tinplate, color coated sheet and other metal products, can be used to prevent rust. Such as steel parts in auto parts factories, copper components in electronics factories, and galvanized sheets in the field of building materials can all be effectively protected by our VCI stretch film.

What should I pay attention to when using VCI stretch film packaging metal parts?

1. Before packaging, the metal surface must be dry and clean. If there is moisture or oil on the surface of the part, the VCI molecules cannot form a complete protective layer.

2. When packing, it should be sealed as well as possible. Although VCI stretch film can work in an enclosed space, try to wrap the VCI plastic tightly to reduce the internal air flow.

3 Pay attention to the placement direction of VCI plastic. Generally, the treated side of the VCI plastic should face the metal surface. When wrapping, ensure direct contact with the parts to ensure the anti-rust effect.

4. Unused VCI plastic should be stored in a cool and dry place, and packaged parts should also be stored in a dry and ventilated warehouse, and should not be in a humid environment for a long time.

5. Understand the anti-rust validity period. The anti-rust effect of VCI plastic is not permanent. According to the estimated storage and transportation cycle of the product, it is necessary to choose the film model with the appropriate anti-rust validity period, and make a good time plan to avoid overdue storage.

6. Operators should wear gloves. Direct contact with metal parts and the inside of the film by hand will affect the anti-rust effect.

VCI plastic market trends:

The VCI plastic market is increasingly developing rapidly in a safer and more environmentally friendly direction. There is an increasing demand for environmentally friendly VCI plastic that are nitrite-free and heavy metal-free. Moreover, the stability of the supply chain and product traceability have also received more and more attention.

CVCI can customize VCI plastic according to the special needs of customers. If customers need films of specific thickness and width, we can adjust the production process; if customers have special anti-rust cycle requirements, we can also optimize the formula to adapt the film to a longer anti-rust time to ensure that it meets the packaging needs of different industries and different parts.

Conclusion:

The correct use of VCI plastic is very important. Pay attention to the details of metal pretreatment, packaging sealing and storage conditions, etc., which can exert a good protective effect and protect your products from corrosion.
