A selection of the most commonly asked questions regarding ecommerce packaging, order fulfillment, and more
What sizes of white postal boxes are available?
We offer a wide variety of sizes to cater to diverse needs. Our Royal Mail PiP boxes are designed for large letters with dimensions no greater than 353 x 250 x 25mm and a maximum weight of 750g. For larger items, our Trojan Fold-Up Postal Boxes range from compact options like 107 x 75 x 55mm to larger sizes like 425 x 165 x 120mm.
Are your white postal boxes eco-friendly?
Yes, white postal boxes are one of the most eco-friendly packaging options available. Made from FSC-certified cardboard and containing at least 70% recycled materials, they are also fully recyclable after use.
What are PiP boxes, and why are they beneficial?
PiP (Pricing in Proportion) boxes are designed to comply with Royal Mail's large letter sizing. They help reduce postage costs while ensuring your items are securely packaged. Ideal for small items and documents, these boxes fit through standard UK letterboxes, offering convenience for customers and businesses alike.
Can these boxes be used for fragile items?
Our Trojan Fold-Up Postal Boxes and larger PiP boxes are made from rigid E-Flute cardboard, providing good protection for fragile items. For extra safety, we would recommend pairing them with additional protective materials like bubble wrap or foam inserts and if possible using “Fragile” printed tape to ensure your items are handled with care.
Do you offer bulk discounts for white postal boxes?
Absolutely. We provide competitive pricing and bulk discounts for wholesale and pallet quantities of white postal boxes, making it cost-effective for businesses with high-volume packaging needs. Equally, we can provide quantities as low as 25 units for lower packaging volumes.
What’s the difference between PiP white postal boxes and Trojan white postal boxes?
PiP boxes are tailored to Royal Mail’s large letter specifications, ensuring cost savings on postage. Trojan boxes, on the other hand, offer a broader range of sizes and are designed for more general shipping needs, providing robust protection for various goods.
