An automatic wrapping machine is being used to quickly and tightly wrap the aluminum coils with VCI stretch film. This ensures uniform and secure wrapping for effective corrosion protection.

The VCI stretch film used appears to contain volatile corrosion inhibitors that vaporize and prevent white rusting or other damage to the aluminum. The film creates a barrier against humid environments and corrosive agents. It has its advantages for aluminum profiles protection.

  • VCI stands for volatile corrosion inhibitors. The film contains chemical compounds that vaporize and protect the aluminum from corrosion.
  • VCI stretch film helps prevent white rust and other corrosive damage to aluminum coils during storage and transit. It creates a protective barrierand also continues to emit corrosion inhibitors over a long period of time.
  • VCI stretch film is elastic and can stretch over uneven coils for a tight, protective wrap. It is also tear resistant for durability.
  • The corrosion inhibitors in the VCI stretch film neutralize corrosive agents like acid, alkali, and salt. It protects against corrosion even in humid environments.
  • VCI stretch film can be used for wrapping individual coils, bundling multiple coils together, or wrapping entire coil stacks. It works for both round and flat coils.
  • Popular types of corrosion inhibitors used in VCI stretch film include salicylic acid, phosphonoacetic acid, and imines. They inhibit corrosion in different ways. Selection depends on the types of metals and corrosive environments

The stretchiness of the film allows it to closely wrap the irregular shapes and uneven surfaces of the aluminum coils without creases or tears. It conforms well to the contours of the coils.

Multiple layers of wrapping with overlap between layers provide comprehensive coverage and extra thickness of protection. The overlaps also help seal the wrap.

The wrapped coils are protected in a corrugated cardboard box for added cushioning, stacking strength and moisture barrier. The VCI film continues to emit corrosion inhibitors even within the box.

According to the description, this technique helps improve the corrosion resistance and lengthen the storage life of the aluminum coils for up to 1 year. The coils can be safely stored in warehouses or transported long distances.

Periodic inspections of the wrapped coils would still be advisable, but the VCI stretch film can create an effective passive protection system against corrosion damage.

In summary, this video demonstrates how VCI stretch film can be used an automatic wrapping machine for thoroughly and comprehensively protecting aluminum coils from corrosion during storage and transportation. The technique showcased can help maximize the usable life of aluminum profiles and master coils.
