Types Of Mailer Boxes

Mailer boxes come in various shapes and sizes to accommodate different products and shipping requirements. Here are some common types of mailer boxes:

  1. Regular Slotted Container (Rsc): RSC mailer boxes are the most basic and widely used type of these boxes.

RSC boxes are versatile and can be used for various products, making them a popular choice for many businesses.

They are easy to assemble and provide a secure closure, making them a popular choice for businesses looking for efficient and hassle-free packaging solutions.

One of the biggest advantages of using these boxes for your business is the ability to customize them according to your brand’s unique requirements. Custom mailer boxes can help you create a lasting impression on your customers, enhance your brand identity, and differentiate your products from competitors. Here are some customization options to consider:

  1. Custom Printing: Custom printing allows you to add your brand logo, graphics, text, and other design elements to your mailer boxes.

Finishing options such as foil stamping, embossing, debossing, and spot UV coating can enhance the visual appeal of your mailer boxes and create a premium look and feel. These finishing options can be applied to your brand logo, graphics, or other design elements, adding a touch of sophistication to your packaging.
  5. Custom Colors: Custom colors allow you to create boxes that match your brand’s color scheme, creating a consistent and cohesive brand image. You can choose from a wide range of colors and Pantone matching system (PMS) colors to create boxes that reflect your brand’s personality and aesthetics.
