Custom Cardboard Envelopes

Custom Printed Cardboard Envelopes

When it matters that your documents, samples or delicate items arrive in perfect condition, cardboard envelopes are the smart choice. Sturdy, professional and fully customisable, they combine practical protection with a polished branded finish — making them far more than just a posting solution. At Pixartprinting, we offer high-quality printed cardboard envelopes in a range of standard formats, with a choice of premium materials, lamination and special finishes, all delivered free of charge, always.

Cardboard Envelopes for UK Businesses

Standard paper envelopes simply aren't built to protect what matters most. Custom cardboard envelopes, on the other hand, are constructed from thick, rigid SBS paperboard that shields your contents from bumps, bending and transit damage — giving you and your recipients complete peace of mind. Whether you're sending contracts, certificates, catalogues, photo albums, CDs or DVDs, our cardboard envelopes ensure everything arrives exactly as it left you.

Printed with your logo, brand colours or a full custom design on the outside, they also turn every delivery into a brand touchpoint — a small but significant detail that sets professional businesses apart.

Custom Cardboard Envelopes for Small Businesses

You don't need to be a large corporation to benefit from branded packaging. Our custom cardboard envelopes are available from just 25 copies, making them an ideal solution for small businesses, independent retailers, photographers, artists and online sellers who want to make a strong impression without committing to large minimum order quantities. With up to 10 different designs available per order, you can create variations for different product lines, seasons or campaigns — all in a single, streamlined order.

Responsible Printing You Can Be Proud Of

All of our cardboard envelopes are printed on SBS paperboard (380 gsm) — a high-quality, matt white board that delivers excellent print results on the front surface. Our FSC™ certification guarantees that the materials used in our cardboard envelopes are sourced from forests managed in accordance with rigorous environmental, social and economic standards. Choosing Pixartprinting means choosing responsible printing from a supplier you can trust.

Lamination and Special Finishes for Cardboard Envelopes

A great design deserves a great finish. Our custom cardboard envelopes can be enhanced with a range of lamination and special finish options that protect your print and elevate the overall presentation:

• Lamination: choose from matt for a refined, non-reflective look; gloss for bold, vivid colours; or soft-touch for a velvety, premium feel that's tactile and distinctive.
• Special finishes: add an extra dimension to your design with 2D or 3D varnish for a raised, glossy effect, or opt for 2D or 3D gold and silver foil — available in gloss or matte — for a luxurious metallic detail that catches the eye and communicates quality.

Printed Cardboard Envelopes with Your Logo

Every detail of your custom cardboard envelope can be tailored to your brand. Print your logo prominently on the front, apply your brand colours across the full surface or create a design that reflects the character of your business — from bold and graphic to refined and minimal. With Pixartprinting, your envelopes become an extension of your brand identity, making an impression before your recipient has even opened them.
