由 caicai8478 I. Core packaging principles
3D protection principles: damping, damp-proof, and displacement
Balanced weight distribution: the weight of a single package shall not exceed 23 tons (railway weight limit) or 26 tons (sea transportation weight limit)
Modular design: the frame and glass components should be packaged separately, and the movable parts should be fixed
II. Classification packaging standards
(I) Glass component packaging specifications
Glass type Packaging method Special requirements
Single-layer flat glass Vertical A-frame + EPE pearl cotton + steel edge corner guard No more than 15 pieces per tray, with a spacing of ≥8mm
Insulating glass Nitrogen-filled packaging + desiccant + shockproof frame Silicone cushions are installed at the four corners
Tempered glass Honeycomb cardboard + explosion-proof film + steel frame Prominently marked “TEMPERED GLASS”
Special-shaped glass Customized foam mold + wooden box packaging Each piece is managed with a separate number
(II) Packaging specifications for door and window frames
Metal frame:
Aluminum profile: PE wrap film + corner guard + corrugated cardboard spacing (spacing ≥ 30mm)
Steel frame: anti-rust oil treatment + vapor phase anti-rust film + VCI anti-rust paper
Composite material frame:
UPVC profile: UV protective film + anti-deformation bracket
Wood-aluminum composite: moisture-proof paper + mildew-proof agent + breathable film packaging
III. Key protection technology
Six-sided buffer design:
Top: 5cm thick high-density EPS foam
Bottom: anti-slip rubber pad + wooden pallet (ISO standard size)
Around: honeycomb cardboard + bubble film composite layer
Dynamic reinforcement plan:

Environmental protection measures:
Humidity control: built-in humidity indicator card + silica gel desiccant (≥ 200g per cubic meter)
Temperature adaptation: – 30℃~70℃ environmental simulation test
Salt spray protection: 96 hours salt spray test is required for sea transportation
IV. Transport adaptation plan
(I) Special requirements for sea transportation
The inner wall of the container should maintain a ventilation gap of 15cm from the cargo
Use container desiccant (8-10 bags per container)
Install anti-condensation blanket on the top layer (especially for Southeast Asian routes)
(II) Key points for railway transportation
Reinforcement focus: vibration protection at track joints
Temperature difference treatment: -40℃ low temperature test is required for cross-continental transportation
Stacking limit: no more than 2 layers and total height <2.8 meters
(III) Special treatment for air transportation
Weight control: single piece ≤80kg (narrow-body aircraft) or ≤150kg (wide-body aircraft)
Air pressure adaptation: packaging must withstand 0.6 atmosphere pressure changes
Static protection: electronic components require ESD packaging
V. Quality verification process
ISTA 3E test:
Random vibration test (sea transport spectrum)
Incline impact (3° incline/48km/h)
Pressure test (continuous 1 hour/500kgf)
Four-step method for on-site inspection:
Chart
Code
Document requirements:
Packaging inspection report (including photos)
Material MSDS certification
Proof of mildew treatment (for wood materials)
VI. Industry best practice cases
Export plan for a certain brand of system doors and windows:
Problem: The breakage rate of sea transport to Germany is as high as 12%
Improvement measures:
Use vacuum adsorption glass handling system
Upgrade to EPP foam mold packaging
Add real-time transport monitoring instrument
Effect: The breakage rate is reduced to 0.8%, saving $280,000 in claims annually
VII. Innovative solutions for 2023
Smart packaging system:
Built-in temperature and humidity sensor + GPS tracking
Impact recorder (threshold ≥ 5G automatic alarm)
QR code traceability system
Application of environmentally friendly materials:
Degradable plant fiber buffer material
Nano-coated moisture-proof paper (thickness 0.3mm replaces traditional 3mm cardboard)
Magnesium alloy corner guard (60% lighter than steel)
It is recommended that companies establish a packaging database to record damage data under different transportation methods and continuously optimize packaging solutions. For high-value products, it is recommended to purchase separate breakage insurance (the premium is about 1.2-1.8% of the value of the goods).
