FAQs

What are letterbox boxes?

Letterbox boxes are packaging with a width and height that allow them to fit through standard UK letterboxes. The length of the pack can be adjusted to accommodate different-sized products. Letterbox packaging allows items to be delivered even if the recipient is not at home.

What products are letterbox boxes suited to?

Letterbox boxes are popular for a wide range of products. They are suitable for games, DVDs, books, brochures, chocolates, clothing, flowers, and any product with similar dimensions. They are also commonly used for subscription box packaging.

Do letterbox boxes adhere to Royal Mail pricing bands?

Letterbox boxes typically fall within the Royal Mail PIP (pricing in proportion) guidelines. These guidelines determine the prices for parcels that they deliver. Adhering to these can further reduce your expenditure through reduced delivery costs.

What are letterbox boxes manufactured from?

Letterbox boxes typically use single-wall cardboard, which allows for maximum space within the pack. However, the specific grade is chosen based on the product’s weight and fragility.

Can letterbox boxes include inserts?

Although letterbox boxes have limited internal space, you can include inserts. Die-cut cardboard fittings or foam packaging inserts (such as Stratocell) are the most common, helping to brace and cushion products from damage during shipping.
