Cardboard Mailer Boxes

Cardboard Mailer Boxes That Make Shipping Simple and Safe 

Shipping boxes need to do more than hold a product. They should keep items safe, stay closed during delivery, and give customers a good first look at your brand. A strong box can also reduce empty space and make packing easier. 

At Umbrella Custom Packaging, we make custom cardboard mailer boxes for online stores, clothing brands, beauty companies, gift shops, subscription brands, bookstores, small businesses, and large retailers. We can change the size, shape, material, printing, and finish to fit your products. 

Whether you ship one small item or a full product set, we can create packaging that is easy to pack and simple to open. In addition, your logo and brand colors can turn a plain shipping box into packaging customers can remember. 

Custom Cardboard Mailer Boxes Made to Fit Your Products 

Products come in many sizes and shapes. Therefore, using the same box for every item does not always work. A box that is too large can leave too much empty space. On the other hand, a small box may not give the product enough room. 

Custom cardboard mailer boxes can be made around the exact size of your item. We can change the length, width, depth, and inside space based on what you ship. As a result, the product can fit better and stay more organized. 

For example, a clothing company may need a flat box for shirts. A beauty brand may need a smaller box with an insert for bottles and jars. Similarly, a gift company may need more inside space for several items. 

Businesses that ship books and printed items can also use our book mailers boxes to help keep products neat and safe during delivery. 

Strong Materials for Cardboard Mailer Packaging Boxes 

The right material helps your packaging stay strong during packing, storage, and shipping. However, the best material depends on the size and weight of your product. Therefore, we offer several board types and thicknesses. 

E-Flute Corrugated Board: Around 1.5 mm to 2 mm thick. It works well for clothing, cosmetics, books, small gifts, accessories, and other light to medium products. 

B-Flute Corrugated Board: Around 2.5 mm to 3.2 mm thick. It gives more strength and works well for heavier items and larger shipping boxes. 

F-Flute Corrugated Board: Around 0.8 mm to 1.2 mm thick. It is thin and gives the box a clean look while still adding useful support. 

Kraft Corrugated Board: Available in about 250 GSM, 300 GSM, 350 GSM, and heavier options. It gives the package a simple and natural brown look. 

White Corrugated Board: Available in different thicknesses, including E-Flute and B-Flute. Its clean white surface works well for colorful logos, graphics, and other custom artwork. 

Recycled Board: Available in different GSM and flute options based on product and box size. It is useful for brands that prefer recycled paper choices. 

FSC-certified and recyclable paper options are also available. So, you can choose the material, thickness, and flute type based on product weight, shipping needs, design, and budget. 

Useful Sizes for Small and Large Products 

Choosing the right size can help keep products in place and reduce extra space. We make fully custom sizes, so you do not have to use only standard dimensions. 

Small Box: 6" × 4" × 2" for jewelry, small beauty items, and accessories. 

Medium Box: 9" × 6" × 3" for cosmetics, gifts, and small retail products. 

Clothing Box: 12" × 9" × 3" for shirts, fashion items, and other soft products. 

Large Box: 14" × 10" × 4" for larger product sets and subscription orders. 

Extra-Large Box: 16" × 12" × 5" for larger gifts, clothing sets, and several products. 

Custom Size: Length, width, and depth can be changed based on the exact size of your item. 

These sizes are only examples. The final size depends on your product, inserts, shipping needs, and the amount of inside space required. 

Add Inserts to Keep Products in Place 

Some products need more support inside the box. Bottles, jars, electronics, glass items, and small gifts may move if there is too much open space. Therefore, custom inserts can help keep each item in the right place. 

Paperboard Inserts: Useful for small and lightweight products. They can help hold items in a fixed position. 

Corrugated Inserts: A stronger option for products that need more support during shipping. 

Dividers: Useful when several items need to stay separate inside one package. 

Custom Compartments: A good choice for gift sets, beauty kits, electronics, and other product sets. 

Inserts can also make the inside of the box look cleaner when customers open it. Therefore, they can help with both product protection and presentation. Brands that send products every month can also use subscription boxes to create matching packaging for regular customer deliveries. 

Simple Finishes for a Clean Shipping Look 

Shipping packaging does not always need expensive finishing. In many cases, clear printing and strong material are enough. However, selected finishes can make custom packaging look more special. 

Available options include: 

• Matte lamination 
• Gloss lamination 
• Aqueous coating 
• Spot UV 
• Gold foil 
• Silver foil 
• Embossing 
• Debossing 
• Inside printing 
• Outside printing 
• Custom die-cut details 

For example, a natural kraft box may only need a black printed logo. On the other hand, a premium beauty company may choose a white box with full-color printing and a small foil logo. So, you can keep the design simple or make it more premium. For smaller and lighter products, kraft mailer boxes are another useful choice when you want simple shipping packaging with a natural brown look.

Working with a Cardboard Mailer Boxes Manufacturer 

Choosing the right cardboard mailer boxes manufacturer is important when your business needs custom sizes and regular orders. A good manufacturer should understand box strength, product size, printing, inserts, and shipping needs. 

At Umbrella Custom Packaging, we create packaging based on the products you actually ship. You can choose the board type, dimensions, artwork, printing method, inserts, and finish. 

This is useful for both new and growing businesses. A small brand may need one simple size. However, a larger company may need several sizes with the same logo, colors, and design.
