How Mailer Boxes Are Made

Printing: We begin by printing on your chosen cardboard using flexography for kraft and offset for white cardboard. This process includes multiple color calibrations to ensure accuracy and vibrancy. Optional finishes like spot UV, glitter, or foil stamping are added for a sophisticated touch.

Composite (For Corrugated Mailer Boxes): Next, we composite brown or white cardboard with a corrugated sheet using strong adhesive, followed by flattening and a two-day natural drying process. This ensures strong cohesion and prevents deformation.

Die-cutting: Die-cutting shapes the boxes with precision, using a combination of sharp and blunt blades. We conduct thorough inspections and calibrations to avoid excess pressure and waste, ensuring each box is perfectly crafted.
Box Cutting and Making: Finally, boxes are shaped and offcuts removed. This step is crucial for final assembly and quality. We use specialized equipment for precision, offering both two-dimensional and three-dimensional options based on your preference.

What Design File Shoule Be Prepared

File Format: Preferred formats: AI (Adobe Illustrator) or PDF for high-resolution artwork.
Resolution:Minimum of 300 DPI (dots per inch) to ensure sharp and clear prints.
Color Mode:Use CMYK color mode, which is best for four-color process printing. Avoid RGB mode to prevent color printing issues.
Fonts: Convert all text to outlines or include the specific fonts used to avoid font replacement issues.
Graphic Elements:All logos, photos, and icons should be high quality and correctly positioned. Provide necessary links and avoid using copyrighted images without permission.
Bleed Area: Usually an extra 3 to 5 mm around the edges, to ensure no white margins appear after cutting and printing.

How To Choose The Materials Of Custom Mailer Boxes

Selecting the right material for your mailer box is crucial to ensure that your products are adequately protected and your brand values are upheld. Here's a guide on how to make this important decision:

Consider Product Requirements: Start by understanding the nature of the products you intend to ship. Fragile or valuable items may require a sturdier and more protective material, while lightweight or non-fragile products may allow for more flexibility.
Evaluate Durability: Assess the durability of the materials available. Corrugated cardboard is a popular choice due to its strength and cushioning properties. Consider the thickness (measured in ECT or Mullen test ratings) to gauge the material’s ability to withstand handling and shipping.
Eco-Friendly Options: If sustainability is a priority, opt for materials made from recycled content or sustainable sources. Look for certifications like FSC (Forest Stewardship Council) to ensure responsible sourcing.
Printing And Customization: Consider the printing quality and customization options for each material. Some materials may provide better printing results and vibrant colors, which can enhance your brand’s visual appeal.
Budget Constraints: Balance your material choice with your budget. While premium materials may offer superior protection and aesthetics, they can be more expensive. Assess how your choice aligns with your overall packaging budget.

How To Assess Quality Without Professional Machinery

You don't need specialized equipment to gauge the quality of your mailer boxes. Here's how to assess their quality with simple methods:

1. Printing Quality: Inspect the printing quality, if applicable. Crisp and vibrant printing with accurate colors and clear text demonstrates attention to detail.
2. Tactile Assessment: Run your hands over the box’s surface. Quality mailer boxes should feel sturdy and free from flimsiness. Check for any loose or unglued seams, as well as the overall thickness of the material.
3. Fold And Closure Test: Fold the box along its creases and secure it using the intended closure mechanism (e.g., tabs, adhesive). A secure and snug fit indicates good craftsmanship.

How To Store Custom Mailer Boxes

Dry Environment:
Store the boxes in a dry place to prevent moisture from weakening the cardboard. Excess humidity can lead to warping or mold.
Temperature Control:
Keep the boxes in a temperature-controlled environment. Extreme temperatures can cause the material to expand or contract, affecting the box’s integrity.
Avoid Direct Sunlight:
Store the boxes away from direct sunlight as UV rays can fade the print and weaken the box material over time.
Stack Carefully:
If stacking boxes, do it evenly and carefully to avoid crushing. It’s best to not stack too high to prevent the bottom boxes from bearing too much weight.
Flat Storage:
If possible, store the boxes flat rather than assembled. This saves space and prevents the boxes from becoming misshapen.

Factors That Influence Prices Of Custom Mailer Boxes

Box Size: The size of the box is a crucial factor in cost determination. Larger boxes require more materials and time to produce, leading to higher expenses.
Material Quality: The type of material used significantly influences the price. Specialty materials tend to be more expensive than standard options.
Printing And Customization: The complexity of printing and customization can increase costs. Additional features like die-cut windows or inserts add to the complexity and, consequently, the expense.
Quantity: The number of boxes ordered impacts the cost per unit. Bulk orders typically result in lower per-unit costs due to efficiencies in production.
