Online businesses are booming day by day, and so does the need for durable packaging. When your order arrives in less than perfect condition, you lose future sales from the same customers. Custom mailer packaging gives UK businesses a practical way to address multiple concerns of brands such as:
- Crushed corners
- Loose products
- Weak closure
- Excessive void space
We design the boxes around your product dimensions that reduce movement and give a professional look. Whether you sell clothing or subscription products, these boxes are easier to handle for all shipping. Choose from suitable paper grades and customisation options based on your product and delivery needs. You can not only balance product protection but also achieve storage efficiency. We manufacture personalised mailer boxes with multiple closure and box styles that are:
Roll End Tuck Top Mailers
This style of custom packaging mailer boxes has extended flaps that wrap around the box and improve strength. The tuck-end closure of the boxes makes sure that the product remains enclosed without complicated assembly. From fashion to cosmetics and subscription boxes, all can use this box style.
Roll End Front Tuck Mailers
These boxes have a reinforced body and a practical front closure. The roll-end tuck mailer design keeps the contents stable during shipping and handling. The style of the wood is perfect for products of medium weight that need more support than a simple folding carton. You can select custom dimensions to further enhance the product fit and reduce unnecessary movement.
Die-Cut Mailer Boxes
In custom postal packaging, a die-cut mailer is one of the unique styles. It has precise cutting that creates specific shapes and folds of the boxes. The die-cut design allows you to get packaging for products with unusual dimensions. Die-cut mailer boxes are used in e-commerce for personalised presentation. You can select further elements in your packaging such as custom inserts and handles.
Corrugated Mailer Boxes
Your custom shipping boxes UK can be manufactured with corrugated material for additional strength. This material has high resistance against compression and impact. The boxes are perfect for products that need high-end courier handling. Inline retail and subscription boxes are manufactured with corrugated material to prevent product crushing and keep them lightweight.
Subscription Mailer Boxes
When brands have to deal with recurrent deliveries, they can select subscription boxes. These custom mailer packaging options for businesses can be matched to monthly product combinations and help improve in-store product movement. Brands can also get the option for custom graphics that will create a recognisable delivery experience.
Materials Used for Quality Packaging
Your packaging material determines the effectiveness of a mailer in protecting the product. A quality material for custom mailing boxes handles stacking and performs well during courier transport. Corrugated and kraft are common materials used in the manufacturing of mailers. Besides these, folding box boards and cardboard are also used. We select the materials that balance:
- Durability
- Weight
- Cost
- Appearance
- Storage requirements
The common materials that we use are as follows:
Corrugated Board
When parcels need additional resistance against crushing and impact, we use corrugated boards. This is a fluted material and provides cushioning and rigidity without making the package excessively heavy. You can get corrugated boxes in mailer style with different flutes to accommodate variable protection requirements.
Kraft Board
For a natural appearance with practical packaging, kraft material can be used. This material is produced from virgin and recycled fibres based on the required specifications. Kraft is suitable for simple and environmentally conscious packaging.
Solid Bleached Board
Brands can select solid bleached boards for custom ecommerce packaging and get a smooth surface with bright printing. This option works well when colour production and clean presentation are important. SBS is a lightweight and premium option for shipping packaging and retail boxes. The smooth surface of the material of custom cardboard mailer boxes accommodates coatings and finishing processes to enhance resistance and visual appeal.
With the use of quality materials and high-quality design services, we provide boxes with the following characteristics:
- Durable structure that withstands courier handling without collapsing.
