Aluminum Export Packing: Paper Interleaving, Film and Wooden Cases

Introduction

Aluminum export packing should protect aluminum plate, sheet, coil, strip, bar, tube, profile and machined parts from scratches, oxidation, moisture, edge damage, deformation and label mix-up during sea, air or truck shipment. For buyers, the key specification checks are packing method, paper interleaving, protective film, moisture barrier, pallet strength, wooden case quality, edge protection, bundle marking, heat/lot traceability and pre-shipment packing photos.

Aluminum materials are lightweight but surface-sensitive. A shipment may meet the correct alloy, temper and size requirement, but still be rejected if the surface is scratched, wet, stained, oxidized or bent after transport. This guide explains the standard scope, aluminum grade and product form considerations, certificate and packing checklist, common buyer mistakes, FAQ and a downloadable packing specification CTA for international aluminum purchasing teams.

Standard Scope for Aluminum Export Packing

Export packing is usually defined by the purchase order, customer packing specification, product form and transport method. Unlike alloy chemistry or mechanical properties, packing requirements are often not fully controlled by one single material standard, so buyers should write packing details clearly in the RFQ and PO.

Scope Item	What Buyers Should Define	Why It Matters
Product Form	Plate, sheet, coil, strip, bar, tube, profile, tread plate or machined part	Different shapes need different packing support and surface protection.
Surface Requirement	Mill finish, brushed, polished, anodized, coated, protective film or visible-face surface	Surface-sensitive aluminum needs stronger scratch and moisture protection.
Transport Mode	Sea freight, air freight, truck transport, LCL, FCL or mixed shipment	Sea freight and LCL usually need more moisture and impact protection.
Handling Method	Forklift, crane, pallet truck, container loading or warehouse stacking	Packing must resist compression, bending, forklift impact and lifting stress.
Documentation	Packing list, case marks, heat/lot labels, MTC and packing photos	Supports receiving inspection and prevents shipment mix-up.

Aluminum Grade and Product Form Packing List

Packing should match both the aluminum grade and product form. Marine grades, polished sheets, thin coils, long profiles and precision machined parts often need more protection than general-purpose industrial stock.

Aluminum Product	Common Grades	Recommended Export Packing
Aluminum Sheet	1050, 1060, 1100, 3003, 5052, 5754, 6061	Paper interleaving, protective film if required, waterproof paper, wooden pallet or wooden case.
Aluminum Plate	5083, 6061, 6082, 7075, 2024, 7050	Strong wooden pallet, edge protection, waterproof wrapping and steel/plastic straps.
Aluminum Coil / Strip	1050, 1060, 3003, 5052, 8011, 8079	Eye-to-sky or eye-to-wall packing, core protection, waterproof paper, outer protection and wooden pallet.
Aluminum Tube / Pipe	6061, 6063, 6082, 5052	Bundle packing, plastic caps, wrapping, wooden case for small or polished tubes.
Aluminum Profile	6061, 6063, 6082	Individual wrapping if surface is critical, bundle protection, separators and long wooden cases.
Machined Aluminum Parts	6061, 6082, 7075, 2024	Individual wrapping, foam separation, thread/edge protection, carton inside wooden case.

Paper Interleaving, Protective Film and Moisture Protection

Paper interleaving and film protection are not decorative details. They are practical measures to prevent surface scratches, staining and metal-to-metal friction during transport. Buyers should specify which surface requires protection and whether the film must be removable without adhesive residue.

Protection Method	Best Use	Specification Check
Paper Interleaving	Sheet, plate, cut pieces, polished surface and visible panels	Confirm paper between each sheet or only between bundles; check dryness and cleanliness.
Protective Film	Decorative sheet, brushed sheet, panels, coated material and visible-face products	Confirm film side, film thickness, adhesive residue risk and removal condition.
Waterproof Paper	Sea freight, humid warehouse storage and long-distance export	Check full coverage and avoid direct water contact with aluminum surface.
Plastic Wrapping	Coil, sheet bundle, tube bundle and export pallet	Protects against dust and moisture, but must not trap existing moisture inside.
Desiccant / Moisture Absorber	High-humidity sea freight, sealed cases and surface-critical goods	Useful when condensation risk is high; does not replace dry packing before sealing.

Wooden Cases, Pallets and Edge Protection

Wooden packing is important for export aluminum shipments because it protects the material from bending, collision, forklift damage and compression during container loading. Long profiles, thin sheets and high-value machined parts need especially careful support.

Wooden Packing Type	Recommended For	Quality Check
Wooden Pallet	Standard plate, sheet, coil and bar shipments	Check load capacity, bottom support, forklift clearance and moisture condition.
Wooden Case	Thin sheet, profiles, tubes, small parts, machined parts and LCL shipment	Check case strength, internal fixing, edge protection, dry condition and case marking.
Crate Packing	Profiles, tubes and long lightweight products	Ensure product cannot slide, bend or rub during transport.
Edge Protection	Sheets, plates, coils, strips and cut blanks	Check corner guards, side protection and strap contact points.
Internal Separators	Machined parts, anodized profiles and polished sheets	Prevent part-to-part friction, surface marks and dents.

Certificate and Packing Checklist

For aluminum export orders, buyers should check not only the material certificate but also the packing documents and photos. This helps prevent disputes about whether damage occurred before shipment, during loading or after arrival.

Document / Check	What It Confirms	Buyer Verification Point
EN 10204 3.1 MTC	Alloy, temper, heat/lot number, chemistry, mechanical properties and standard	Check grade and temper match the purchase order.
Dimensional Report	Thickness, width, length, OD, wall, tolerance, flatness and quantity	Confirm dimensions before goods are packed and shipped.
Surface Inspection	Scratches, stains, oxidation, dents, edge damage and film condition	Important for sheet, plate, coil, profile and visible surface products.
Packing List	Case number, size, quantity, net weight, gross weight and package count	Must match labels, marks and commercial invoice.
Packing Photos	Paper, film, wrapping, pallet/case, edge protection, labels and case marks	Useful proof of pre-shipment packing condition.
Loading Photos	Container condition, pallet placement, lashing, stacking and cargo protection	Important for LCL/FCL export and insurance claim support.

Specification Checks Before Shipment

Before approving shipment, buyers should verify that material, packing and documents are consistent. Packing should be checked before container loading, not only after arrival.

✅ Confirm alloy, temper, standard, size, quantity and heat/lot number.

✅ Confirm surface condition: no harmful scratches, oxidation, water stains, dents or edge damage.

✅ Confirm paper interleaving is used where sheet-to-sheet protection is required.

✅ Confirm protective film side, coverage and film condition for visible-face products.

✅ Confirm waterproof paper, plastic wrapping and moisture protection are applied before wooden packing.

✅ Confirm wooden pallet/case is dry, strong and suitable for forklift handling.

✅ Confirm labels show grade, size, heat/lot number, quantity, PO number and case number.

✅ Confirm packing list, MTC, surface inspection and packing photos are received before shipment.

Buyer Mistakes to Avoid

Only specifying the aluminum grade and size: Grade and size do not define export packing. Buyers should specify paper, film, pallet, wooden case and moisture protection if needed.

Ignoring surface sensitivity: Decorative sheet, brushed sheet, anodized material and visible panels need stronger protection than ordinary machining stock.

Using wet or weak wooden packing: Damp wood, weak pallets or poor internal support can cause oxidation, stains, bending and case damage during transport.

Forgetting edge protection: Aluminum sheet, plate and coil edges are easily dented by straps, forklift impact and rough handling.

Not requesting packing photos: Without photos, it is harder to prove whether scratches, water stains or case damage happened before or after shipment.

Sealing moisture inside the package: Plastic wrapping should protect dry material, not trap condensation or wet paper against the aluminum surface.

Mixing lots without clear labels: Labels, packing list and MTC should match each lot, alloy, temper and size.
