Things To Consider Before Choosing Between 3-Ply, 5-ply, And 7 Ply Corrugated Boxes 

1. Weight of product – Lightweight products may use 3 ply boxes, but if you are shipping heavier items, then you may need something more durable like 5 or 7 ply boxes. However, this is not always the case. 

2. Fragile items – If you are shipping glass, electricals or fragile parts, you may want to use a sturdier box with extra padding or inserts. 

3. Stackability – If you are going to be stacking the cartons, you may want to choose one that has good compression strength and stack height. 

4. Transport – If you are transporting goods over long distances, frequently or exporting, your packaging needs may be greater. Choose a box that will suit the distribution environment. 

5. Cost of packaging – Whilst the packaging may be cheaper, it may result in more damage to your product. Consider the cost of the packaging, how well it protects the product, the weight, and how easy it is to store. 

6. Paper quality – The number of plies doesn’t always determine how strong the box will be. The paper GSM, burst strength, Edge Crush Test (ECT), and flute profile will also have an effect. 

Which Corrugated Box can be Effective based on your business?  

Based on your work process, products, and business workflow, you need to choose the right category of corrugated box.  

• Choose 3 Ply corrugated boxes if your company delas with small and lightweight products, specific-size parcels, and has a low budget for packaging solutions.  
• Choose 5 ply corrugated boxes if you primarily deal with mid-size and duty products. Also, if you are looking for a decent cushioning effect for fragile products, you can opt for 5 ply.  
• Choose 7 ply corrugated boxes if your organization deals with heavy-duty product manufacturing.
