What's the wrapping packaging of copper coils?

Copper is a kind of good material in terms of it's characteristics of anti-rust, anti-errosion and high reformability compare with other metal material such steel and aluminum...... but, it's also a fragile material just as the other metal. It needs protective package especially when it's made as the special and high value products such as copper tubes, copper wire, copper strip and copper pipes. Because these products is not just need to have good functions but also need to have a nice exterior. Any damage such as a scratch, a stain or a torn package could lead to a bad sale or lower price to the owner and make the seller to have a lower profit or even lose money.

Take the air conditioning copper tubes as an example. If the copper coils are packaged by only layer of thin plastic bag, the package could be easily torn by the abrasion, hit during the storage or transportation. The torn package will be less protective to rain and dust. After a long time of storage in the warehouse, the products will be covered by dust and have stains look dirty. But if the copper coil is packaged by reinforced wrapping with one layer or even more layers of thick film and tape, such as LLDPE stretch film, HDPE film and PP belt or composite paper. It will unable to be scratched or wear no matter how you throw it, ship it or store it.

The copper coil wrapping machine uses stretch film/tape or composite paper....as packing materials to pack various circular items such as steel coils, bearings, tires, copper coils, etc by winding. It replaces manual winding packaging with faster wrapping speed. Convenient operation but great production efficiency, and the labor intensity of the workers is reduced. The wrapping effect is neat, beautiful with good tension. Dust-proof, moisture-proof, and protect the surface of the product for transportation and storage, and improves the product’s exterior.

The main characteristic of the copper coil wrapping machine:
  1. Wide range of applicability, special sized products will have specific design.
  2. The main board is adjustable with heights to adapt to different sized coils through wheels.
  3. Separated electrical cabinet for safe operation and technical testing and trouble-shooting.
  4. Using PLC programmable control with simple and clear operation panel, automatic error warning by indication lamp.
  5. Different packing materials are available to use according to packaging requirements.
  6. The tension of the wrapping material can be adjusted.
  7. The supportive rollers and protective side rollers in contact with the surface of the products are all coated with anti-wear polyurethane, to protect the products.
  8. The turning ring speed as well as supportive roller speed regulated by frequency converters, convenient to adjust overlap ratio (20%-90%) according to the packaging requirements.
  9. Motor overload protection, avoid possible damage and extend the service life.
Guardrail is adopted for safe operation.
