32 ECT Vs. 200# Mullen Test Boxes? Choose The Right Box

When it comes to selecting the right corrugated cardboard box for shipping and packaging, the choice can be confusing. At SupplyLand, we often get questions about the differences between 200# Mullen Test boxes and 32 ECT boxes. This is especially true when some large vendors prefer the heavier 200# boxes.

But here’s the truth: in many cases, this added weight and cost aren’t necessary for most consumer goods

Two commonly used types are 200# Mullen-rated and 32 ECT (Edge Crush Test) boxes. Though they may look alike, each has unique features that impact stacking strength, bursting strength, and cost-effectiveness. Here is a quick guide to help you choose the best corrugated box for your needs.

Understanding the Ratings: 32 ECT vs. 200# Mullen Test

32 ECT (Edge Crush Test): Measures stacking strength—how much weight a box can bear per inch of edge. Lightweight and versatile, 32 ECT boxes are ideal for products where stacking strength and cost efficiency are key.
200# Mullen Test: Measures bursting strength—how much pressure the box can withstand before bursting. This makes 200# boxes perfect for heavy-duty items or shipments that require extra protection against rough handling.

Quick Comparison Guide: Choosing the Right Box for Your Needs

32 ECT Boxes: Ideal for lightweight, stackable items like apparel, books, and standard consumer goods. They’re cost-effective and perfect for e-commerce shipping, reducing both material and shipping expenses without compromising on performance.

200# Mullen Test Boxes: Better suited for shipping heavier and bulkier items that require additional strength. They excel with products that have sharp edges or unusual shapes, but their usage is becoming more niche as industry demand shifts toward ECT-rated options.

Pros and Cons of 32 ECT Boxes

Advantages:

Lightweight and Cost-Effective: Designed to minimize shipping costs while maintaining ease of handling.
Eco-Friendly: Require less raw material, making them an excellent choice for businesses focused on sustainability.
Excellent Stacking Strength: Ideal for lighter goods like clothing, books, and smaller electronics.

Disadvantages:

Not Optimal for Heavy-Duty Items: For extremely heavy products or items with sharp edges, additional bursting strength may be needed, which Mullen Test boxes can provide.

Focused on Standard Applications: While 32 ECT boxes are available in a wide range of sizes, they are optimized for standard, lightweight shipping needs and may not be suitable for highly specialized applications.

Pros and Cons of 200# Mullen-Rated Boxes

Advantages:

Superior Strength: Offers added protection for extremely heavy or fragile items, making them reliable for long haul demanding shipments.
Trusted for Fragile Items: Commonly used for high-value goods like electronics and glassware that need extra care during handling.
Durable for Long-Distance Shipping: Ideal for international or long-haul shipments, where added protection is required.

Disadvantages:

Higher Shipping Costs: The additional weight of Mullen Test boxes increases overall shipping expenses.
Bulkier and Less Flexible: Heavier and harder to handle compared to 32 ECT-rated boxes, which are more versatile for modern logistics.

While Mullen Test boxes excel in these niche areas, the demand for them is declining due to advancements in ECT-rated boxes, which now meet most shipping and packaging needs at a lower cost and weight.

Breaking the Myth: Heavier Boxes Aren’t Always Better

There's a widespread misconception in the industry that heavier, thicker boxes are always the superior choice for shipping. While 200# Mullen Test boxes do provide added strength, they can significantly increase shipping costs without offering substantial benefits for lighter items. For many e-commerce and consumer goods, 32 ECT boxes deliver reliable protection and quality at a more cost-effective price, making them an excellent choice for everyday shipping needs.

32 ECT high-quality boxes are the ideal choice for businesses focused on cost-effectiveness and lightweight shipping.
