What is your standard packaging method for heat sinks?
Aluminum heat sinks may look sturdy, but they’re surprisingly vulnerable during shipping—especially those with thin fins or long profiles.
We use a multi-layer packaging system including foam, shrink wrap, and export-grade cartons or wooden crates to protect every heat sink.
Our approach to packaging isn’t just about safety—it’s about protecting your production schedule, your costs, and your brand reputation.
Do you offer shock-proof or export-grade packaging?
Shipping isn’t smooth sailing. From forklifts to customs inspections, your heat sinks can face a lot before they reach you.
Yes, we offer shock-proof and export-grade packaging designed to withstand rough handling, moisture, and stacking pressure during international transit.
We know how easily an unprotected heat sink can be dented or scratched during shipping. That’s why we use industrial packaging solutions compliant with global export requirements.
Export-Grade Packaging Overview
| Feature | Description |
|---|---|
| ISPM 15 Wooden Crates | Internationally approved crates for ocean freight |
| Shock-absorbing Foam | Reduces impact stress during long-haul transport |
| Anti-Moisture Barriers | Prevents corrosion caused by humidity |
| Palletized Cartons | Easy stacking and forklift handling |
In every shipment, we secure the packaging with strong bands and apply clear labeling for customs clearance and warehouse teams. Our crates are designed to keep the product intact, even if dropped from moderate heights.
Sinoextrud offers shock-proof and export-compliant packaging for all overseas orders.True
Our packaging is designed to handle long-distance shipping stress and meet international standards.
Standard packaging is only suitable for domestic shipping, not export.False
Our standard method is export-ready, and we regularly ship globally.
Can packaging be customized for fragile fins?
Fragile fins are tricky. Even a little pressure or vibration during shipping can bend or crack them. Standard bulk packaging just doesn’t cut it.
Yes, we offer customized packaging for fragile fins using foam inserts, dividers, and vacuum wrapping to eliminate risk during transit.
Some fins are thinner than a credit card. For these profiles, we build separate compartments using soft foam trays or thick corrugated partitions. We also use bubble cages or stretch film if extra shock absorption is needed.
Protective Packaging for Fragile Fins
| Custom Option | Benefit |
|---|---|
| Foam Tray Inserts | Isolate each unit to prevent metal-to-metal contact |
| Corrugated Partitions | Distribute pressure evenly across all items |
| Vacuum Wrap | Holds units tightly in place, minimizes shifting |
| Bubble Cage Wrapping | Adds air cushioning for vibration control |
For fragile fins used in LED lighting or electronics, we’ve helped customers cut their damage claims to zero by switching to custom slotting and boxing.
Custom packaging is available for fragile fins to prevent bending and abrasion.True
We provide foam trays, dividers, and vacuum sealing for added protection.
All heat sinks are packed the same, regardless of fragility.False
We tailor packaging based on fin thickness, length, and end-use application.
How are long profiles protected during shipping?
Long aluminum profiles look clean and precise coming off the extrusion press—but one shipping error, and they’re warped beyond use.
We protect long heat sink profiles using reinforced wooden crates, foam padding, and mid-point supports to prevent bending or twisting.
Many clients order heat sink profiles over 3 meters long for architectural, solar, or industrial installations. These require specialized packing to ensure structural integrity.
Long Profile Packaging Strategy
| Protection Method | How It Works |
|---|---|
| Full-Length Wooden Crate | Encases the entire profile in a rigid shell |
| Foam or Felt Wrapping | Prevents scratches and surface abrasion |
| Central Support Blocks | Stops profiles from sagging under their own weight |
| Edge Reinforcements | Avoids chipping or compression from stacking |
We also bundle profiles in small groups with PE film before placing them in the crate, which adds another layer of safety. For sea freight, we sometimes include moisture indicators and desiccant packs inside the box.
Long profiles are packed in reinforced crates with internal supports to avoid bending.True
Proper bracing keeps profiles rigid and damage-free, even over long distances.
Long aluminum profiles are shipped loose in standard boxes.False
This method would result in high damage rates—we use crates and structured protection.
Are eco-friendly packaging options available?
Many of our customers are in renewable energy and green tech. It’s not just their products—it’s their principles. And they expect packaging to align.
Yes, we offer eco-friendly options like recyclable kraft paper, biodegradable foam, and FSC-certified cartons for sustainable shipping.
We’ve made it easier to reduce your environmental footprint. We’ll replace plastics with paper-based alternatives, use water-based adhesives, and avoid coatings that complicate recycling.
Green Packaging Materials
| Material | Environmental Benefit |
|---|---|
| Kraft Paper Wrap | Biodegradable, easily recyclable |
| FSC Carton Boxes | Responsibly sourced paper fibers |
| Biodegradable Foam | Breaks down safely after disposal |
| Recyclable PE Films | Can be reused or collected for recycling |
This is especially popular with clients shipping to Europe, where local regulations often require sustainable materials. We’re happy to build green into your packaging specs.
Eco-friendly packaging is available, including kraft paper and biodegradable foam.True
We support sustainable options for customers who request recyclable or compostable materials.

We offer several green alternatives tailored to customer requirements.
Conclusion
Packaging isn’t just a box—it’s a protection strategy. From shock-proof crates and fragile-fin foam trays to long-profile braces and eco-friendly wraps, we design every detail so your heat sinks arrive in perfect condition.
