Learn more about Self Seal Postal Boxes

Packaging Supplies ever-growing range of postal boxes is everything you need to mail your product safely and securely.

Our self seal mailing boxes can give you a more presentable feel than a standard single or double-wall 0201 style cardboard box. This range has been designed to be functional, sturdy and versatile. Send your product in the highest quality product without a guilty conscience.

These die-cut cardboard self seal boxes fit perfectly within retail and gift packaging sectors, which are widely used in the fashion, eCommerce and boutique industries.

What features do these self seal postal boxes have?

These self-seal postal and mailing boxes have a fold-down hinged lid, with a peel and seal closure and tear open strip.  This means no additional tape is needed to secure your box for posting, meaning you can feel confident with a tamper-proof box and your customer gets a great unboxing experience.

Pricing in Proportion Sizes

Packaging Supplies have given, where applicable, the Royal Mail PiP (Pricing in Proportion) mailing guide, so that you can estimate the delivery costs of your product in a given size of the box.

For example, boxes in this postal box range fall into a small parcel bracket, which has the maximum dimensions of 450mm (L) x 350m (w) x 160mm (H) and a maximum weight of 2kg.

Packaging Without a Guilty Conscience 

This product is part of our ‘Plastic-free, recycle me’ range, part of our mission to create good quality packaging that is as gentle as it can be on the environment.

This specially-engineered board is not just 100% recyclable but also made from 100% recycled content – and all this without losing on performance. 

The P flute used in this range has the added benefit of being thinner in appearance than other commonly used flutes, this means you can pack 30-35% more on a pallet compared to the B flute, which all helps towards improving the carbon footprint.

Expert packaging suppliers for over 40 years, with an emphasis on plastic-free packaging

In the late 1970s, two friends and colleagues, Tim Allen and Stewart Middleton saw a gap in the market for a different type of packaging supplier. At the time, other businesses were selling custom made boxes and stocking packaging consumables, but Tim and Stewart wanted to offer more than that. They wanted to give their clients additional services, such as warehouse storage and the ability to have their packaging delivered as and when it was required. Packaging Supplies was established, and the rest is history.
