Double Wall Corrugated Sheet: A Strong and Versatile Packaging Solution

Blog Article

In industries where strength, durability, and protection are crucial, double wall corrugated sheets have become a go-to solution. These sheets offer superior strength and are widely used for packaging, shipping, and even in some construction applications. This article explores what double wall corrugated sheets are, how they’re made, and where they’re used.



What is a Double Wall Corrugated Sheet?


A double wall corrugated sheet is made up of two layers of fluted paper (corrugation) sandwiched between three linerboards. This creates a strong and thick sheet that can handle heavier loads compared to single wall sheets.



Structure Breakdown:




  • Outer liner




  • First fluted layer




  • Middle liner




  • Second fluted layer




  • Inner liner




This layered structure enhances the sheet’s ability to withstand pressure, impacts, and stacking weight.






Key Features


1. High Strength and Durability


Double wall sheets are ideal for packaging heavy or fragile items due to their rigid and stable structure.



2. Excellent Shock Absorption


The two fluted layers provide extra cushioning, reducing the risk of product damage during transit.



3. Recyclable and Eco-Friendly


Made from paper-based materials, these sheets are often recyclable and biodegradable, making them a sustainable option.



4. Versatile Usage


Can be used for packaging, protective padding, dividers, and even temporary structures in industrial settings.






Manufacturing Process




  1. Corrugation: Kraft paper is passed through heated rollers to form flutes.




  2. Adhesion: The fluted paper is glued between linerboards using strong adhesives.




  3. Assembly: Two fluted layers and three liners are combined to create the double wall structure.




  4. Finishing: The sheet is cut, shaped, or printed according to its final use.







Common Applications




  • Industrial Packaging: For machinery, electronics, and automotive parts.




  • Shipping Boxes: For heavy-duty transportation.




  • Retail Displays: Providing both structure and aesthetic appeal.




  • Protective Barriers: Used in construction sites or warehouse dividers.




  • Storage Solutions: Long-term storage boxes for bulky or sensitive items.







Comparison: Single Wall vs Double Wall Corrugated Sheet







































Feature Single Wall Double Wall
Layers 1 flute + 2 liners 2 flutes + 3 liners
Strength Moderate High
Weight Capacity Light to medium loads Heavy loads
Cost Lower Slightly higher
Best For Standard packaging Heavy-duty and protective uses






Conclusion


The Double Wall Corrugated Sheet is a practical and reliable solution for industries needing strong, protective, and eco-friendly packaging materials. Whether for shipping, storage, or structural use, its durability and versatility make it an indispensable product across many sectors.
