In the world of packaging, not all corrugated boxes are created equal. Behind every sturdy box is a critical detail that most buyers overlook — the flute type. Whether you’re packaging electronics, apparel, food, or pharmaceuticals, the type of flute inside your corrugated board directly affects your product’s protection, stacking strength, and cost.
At ANIPACK Packaging Industries, we work with top-tier B2B clients across Pakistan to select and produce the perfect flute type for their needs. Here’s a breakdown of what flute types are — and which one might be best for you.
What is a Flute?
A flute is the wavy layer sandwiched between the two flat linerboards of a corrugated sheet. This structure:
- Provides cushioning and rigidity
- Adds crush resistance
- Helps with stacking strength
- Affects printing quality and box thickness
Different flute types offer different benefits. Let’s look at the most common types used in industrial and commercial packaging across Pakistan.

Clients needing maximum protection during transit, especially for export or long-haul distribution.

Combo Flutes: Did You Know?
Sometimes, we combine two flute types in one board (e.g., BC Flute) to provide double protection — one for stacking strength, another for cushioning. Ask us if a double-wall setup is right for your fragile or export-grade items.
Final Word: What Flute Type Should You Choose?
At ANIPACK, we help you decide based on:
- Product weight and fragility
- Transportation method (local vs export)
- Desired box thickness and visual finish
- Budget and storage concerns
You don’t need to become a packaging expert — that’s our job. Just tell us what you’re shipping, and we’ll recommend the best structure for maximum safety, minimum waste, and optimal cost.
