Benefits of Corrugated Mailers
Why choose corrugated mailers over other packaging types? Here’s what you gain:
1. Outstanding Protection
The fluted corrugated construction absorbs shock, resists crushing, and shields contents from harm.
2. Lightweight Efficiency
Enjoy robust protection without unnecessary weight. This can reduce shipping costs, especially for high-volume senders.
3. Easy Assembly
Many modern mailers feature quick-fold designs, reducing packing time and frustration.
4. Versatility in Sizing and Applications
From flat mailers for photos to deep boxes for electronics, there’s a shape and size for nearly every product.
5. Professional Appearance
Choose crisp white or classic kraft. Add custom printing for branded impact—first impressions count!
6. Eco-Friendly Choices
Many mailers are 100% recyclable. Look for mailers made from recycled materials for a reduced carbon footprint.
7. Cost-Effectiveness
Corrugated mailers are often less expensive per unit than rigid alternatives, especially in bulk.
How to Choose the Right Corrugated Mailer
Selecting the most suitable corrugated mailer involves evaluating several factors:
1. Determine Your Contents
- Size: Measure your product’s length, width, and height. Your mailer should offer a snug (but not tight) fit.
- Weight & Fragility: Heavier or delicate items may require double-wall or heavy-duty mailers, potentially with cushioning inserts.
- Quantity per Shipment: Will you send single items or bundled sets? Choose mailers large enough for everything, but not excessively so.
2. Choose the Mailer Style
- Tuck Top/Roll-End: Great for general shipping and easy access.
- Tab Lock or Tamper-Evident: For added security, especially for sensitive or high-value goods.
- Literature Mailers: Ideal for documents or flat items.
- Custom Print: Excellent for branding and memorable unboxing experiences.
3. Color and Finish
- Kraft (Brown): Hides scuff marks, practical, and classic.
- White: Clean and professional; enhances custom printing.
- Custom Print/Foiling: For upscale branding or promotions.
4. Pack Size and Bulk Ordering
If you regularly ship, order mailers by the case to achieve cost savings and ensure you’re never out of stock.
5. Sustainability Features
Look for options with high recycled content, or that are clearly marked as recyclable/compostable if environmental impact matters to you.
Practical Tips & Best Practices for Corrugated Mailer Selection and Use
Sizing and Packing
- Size up mailers carefully for each product—overly large boxes lead to excess postage and more packaging waste.
- Use filler (bubble wrap, paper) if there is any extra space to prevent content from shifting.
- For literature or photo mailers, select “rigid” or reinforced options to prevent bends.
Assembly and Closure
- Fold mailers along the scored lines for a crisp, firm shape.
- When using a tuck-top design, ensure the flaps are properly closed for structural strength.
- Consider sealing edges with packing tape for heavy contents or upgraded security.
Shipping Considerations
- Confirm the max weight recommendation for your selected mailer style—avoid overpacking.
- When branding is key, opt for white mailers with custom printing and clear graphical placement.
- Flat mailers save on dimensional shipping costs for papers or photographs.
Storage & Handling
- Store unused mailers flat and dry to prevent warping or softening.
- Stack filled mailers with heavy items on the bottom to maintain alignment and strength.

FAQ
What is a corrugated mailer?
A corrugated mailer is a packaging box made from fluted, layered cardboard, providing a lightweight yet durable way to protect and ship a wide range of products.
How do corrugated mailers differ from standard cardboard boxes?
Corrugated mailers typically have quick-fold, tuck-flap, or tab-lock closures for easy assembly, and are generally single-piece designs. Shipping boxes are often larger, require tape, and may need more assembly time.
Can I use corrugated mailers for heavy or fragile items?
Yes, but choose heavy-duty or double-wall corrugated mailers for extra weight or fragile goods, and consider adding cushioning inside for optimal protection.
Do corrugated mailers come in different sizes and colors?
Absolutely. Sizes range from small (3″ x 3″ x 1″) to large (over 19” long), and most are available in kraft brown or bright white. Custom colors and printing for branding are also offered.
How can I ensure my products fit perfectly in a mailer?
Measure your items (including any internal packaging) and select a mailer that’s slightly larger. Avoid too much extra space, which can lead to product shifting.
Are corrugated mailers environmentally friendly?
Most are recyclable and often contain recycled content. Always check product specifications for eco-friendly features if sustainability is a priority.
Can I get custom-printed corrugated mailers?
Yes. Many suppliers offer custom branding, allowing you to print logos, designs, or even messages for marketing and personalization.
How should I store unused corrugated mailers?
Store them flat, in a dry location, away from direct sunlight and moisture. This maintains their structural integrity and keeps them ready for easy assembly.
What closure options are available for corrugated mailers?
Closure types include fold/tuck-tops, tab locks, adhesive strips (self-seal), and sometimes require tape for added security.
When should I choose a literature mailer vs. other styles?
Literature mailers are best for shipping documents, catalogs, books, or anything that needs to remain flat and protected. Choose other styles for bulkier, three-dimensional, or heavier products.
With this guide, you’re prepared to choose the perfect corrugated mailer for your shipping, presentation, and protective needs. Consider your contents, shipping requirements, and branding goals—and select with confidence.
