To effectively package copper tubes, polyethylene shrink films customized for copper tube wrapping must be utilized. Polyethylene is chemically compatible with copper and resistant to corrosion, moisture, and oxygen permeation. It provides an airtight and waterproof barrier for the tubes.
For efficiency, smaller diameter copper tubes can be bundled together with straps before shrink wrapping each tube individually. However, larger tubes are usually wrapped separately. The straps must not constrict the tubes.
Each wrapped tube or bundled package must be clearly labeled with specifications such as tube details, contents, quantity, etc. This enables easy identification and inventory management.
The wrapped tubes are stacked on pallets in a nested fashion for storage and shipping. The bottom layer is secured to the pallet. The secured packages are then wrapped with stretch wrap or shrink film and sealed at the edges with tape.
The shrink film must adhere to the entire length of each tube for complete encapsulation. No gaps or tears should be left where contaminants or moisture can seep in.
The shrink film is carefully shrunk around the tubes using a tube shrinker or pancake shrink wrapper. Heat is applied uniformly avoiding scorching of the tubes or films. Proper shrinking results in a snug, transparent cover.
It is imperative to test the packaging on samples to check for any damage before mass production. Appropriate improvements to materials or process are implemented accordingly.
Some additional tips:
• Use UV stabilized films for outdoor storage.
• Include breathable films for certain tubes.
• Print tube details on films for easy identification.
The recommendations aim to effectively and safely package copper tubes while ensuring protection from environmental damage, contamination, moisture, and corrosion during storage and transportation. Please let me know if any clarification is needed or if you have additional questions. I can also suggest equipment suppliers or provide visual examples if required.
