The packaging method for copper materials should take into account oxidation resistance, physical damage resistance, stability, and cost control. The specific choice depends on the material form, transportation distance, and storage environment. The following are the main packaging methods and applicable scenarios:

1、 Basic packaging method

wooden case packaging

Applicable: Large copper plates, precision copper strips, and export copper tubes.

Features: Inner lining with rust proof paper/plastic film+desiccant (silicone), outer layer reinforced with steel strip. Pressure and moisture resistance, in compliance with the Maritime Fumigation Standard (ISPM15).

Disadvantages: High cost and bulky.

Tray wrapping film packaging

Applicable: Copper coils, copper plates, pipe/bar bundles.

Features: Copper materials are stacked on wooden/plastic pallets → fixed with high-strength wrapping film → supplemented with steel straps for bundling.

Space saving, easy for forklift handling, dustproof and moisture-proof (basic level).

Steel/plastic strapping

Applicable: Bundled copper pipes, copper rods, and wire reels.

Features: Cross or cross shaped bundling to prevent scattering, often used in conjunction with pallets or bare packaging.

2、 Anti oxidation special packaging

(Core used for easily oxidizable materials such as pure copper and precision copper strips)

Vacuum+VCI packaging

Step: Copper strip passivation treatment → VCI anti rust paper interlayer pad → Vacuum sealing (nylon composite bag) → Add desiccant.

Advantages: Completely isolated from oxygen/water vapor, rust proof period of up to 2 years, suitable for export.

Gas phase rust proof bag (simplified version)

Copper material is directly packed into a polyethylene bag containing VCI particles, and after sealing, the rust proof particles form a protective film.

Applicable: Small copper materials for short distance transportation, oil-free, transparent and visible.

Heat shrink film/plastic bag sealing

Copper pipes and fittings are heat sealed in PE bags or covered with heat shrink film, and desiccants are placed inside to achieve moisture and dust prevention.

3、 Customized form scheme

The recommended packaging method for copper strips/foil rolls is vacuum+VCI paper in a wooden box/iron frame. Key protection points, incision sealing, anti side oxidation

The recommended packaging method for copper plates/ingots is wooden crates (for export) or steel straps tied with rust proof film (for short distance). Key protection points, pressure and moisture resistance, edge reinforcement

The recommended packaging method for copper pipes is wooden pallets, circular paper pads, sponge compartments, and wrapped film. Key protection points, anti friction between pipes to avoid scratches

The recommended packaging method for copper wire/wire material is cardboard layering+cross shaped bundling or heat shrink film pallets. Key protection points, anti scattering and moisture-proof

4、 Balancing Logic and Cost

Anti oxidation priority:

High value/precision copper materials (such as copper strips): vacuum+VCI>rust proof bag>ordinary seal.

Ordinary copper material: wrapping film/bundling+desiccant is sufficient.

Transportation scenario:

Sea freight/export: fumigated wooden boxes+vacuum rust prevention (pressure and moisture resistance).

Domestic land transportation: pallet wrapping+steel strapping (cost reduction of 30%~50%).

Physical protection:

Deformable material (thin copper strip): add foam/cardboard buffer inside the wooden box.

Heavy duty materials (copper ingots): Bare bundling, but need to prevent lifting scratches.

Summary:

Precision copper material: passivation+VCI rust prevention+vacuum sealing+wooden box.

Bulk copper material: pallet winding+steel strip bundling+outer rust proof film.
