5 Smart Tips for Packing Multiple Items in a Mailer Box

When your customer orders several items at once, packaging becomes more than just containment — it’s about protection, branding, and presentation. Getting it right ensures every item arrives intact, every customer feels valued, and your unboxing becomes part of your brand story. Here are five refined tips from DIYPack to help you pack multiple items in a mailer box with care, efficiency, and style.

1. Plan Your Packing Strategy Before You Start

Effective packing begins with a layout. Before filling the box, examine all items — shapes, fragility, weight — and sketch a rough plan. Identify which items need extra padding, which can lie flat, and how to stack items to maximize space while avoiding pressure points or stress on delicate pieces.

2. Prioritize Weight and Size Order

Place heavier, bulkier items at the bottom of the box to create a stable base. Lighter items go closer to the top. This positioning reduces shifting during transport and helps avoid damage from pressure or crushing. For very heavy items, consider reinforcing the bottom of the box or investing in stronger flute sizes available at DIYPack for larger boxes.

3. Separate and Cushion Each Item Properly

Each product should be independently wrapped or lined to prevent rubbing or collisions. Use sustainable void fill such as recycled paper, molded pulp, or kraft inserts between items. Where gaps exist, fill with cushioning material — while avoiding excessive packing that results in bulging sides. Snug, well-structured packing keeps everything safe without wasting materials or increasing box size unduly. Have an order larger than 1,000? Contact us to talk about how we can help with kraft inserts.

4. Keep Box Size and Flute Strength Optimized

Right-sized packaging isn’t just better for the environment — it’s better for your bottom line. At DIYPack, boxes are adjusted in flute size based on square footage to ensure strength without excess bulk. Choose a box that’s just big enough to hold your items and necessary cushioning. Oversized mailer boxes add cost, allow more movement, and may degrade unboxing impact.

5. Verify Every Order Before Sealing

Take the time to inspect the contents before sealing the mailer. Cross-reference against the order summary to ensure nothing is missing. Check that everything is cleanly wrapped, aligned correctly, and protected. A final inspection helps reduce returns and build customer trust in your reliability and attention to detail.

Why These Tips Matter for Your Brand’s Reputation

Quality packaging signals professionalism. When all items arrive safely and beautifully presented, your customer’s experience extends beyond the product itself. They share unboxings, remember your brand, and are more likely to become repeat buyers. With DIYPack’s range of corrugated mailer boxes, design tools, and sustainability features, you have everything you need to make packaging a strategic asset, not just a necessity.
