FAQ

We do not offer the option of printing inside in cardboard envelopes through our standard range. However, if you need that option, please use the service of request a quote.

We offer two sizes of cardboard envelopes C4 (32.4 cm x 32.9 cm) which is perfect for an A4 document and C5 (22.9 cm x 16.2 cm), which fits an A5 document.

Both white and natural kraft are made from the same material, carton. Carton is lighter than cardboard, has lower grammage and doesn’t include fluting (layers made from recycled paper).
White carton is recommended if you wish to print large parts or the entire box in a solid colour. The natural kraft option works best for minimalist designs, or along with darker colours – deep brown, black or navy blue. Check out the Inspirations page to see the differences between white and natural kraft wine boxes, or order a sample pack and check it out in the flesh.

Rigid yet beautiful. Custom cardboard envelopes are perfect for shipping flat items, soft goods, photos, wedding invitations, prints, and just about any type of document. They are available in white or natural kraft and sealed with a peel-and-seal strip.

Custom Envelope Sizes

Our envelopes come in a variety of sizes, all of which are strong, durable and can be used for a variety of problems. Sending standard A4 documents or paperwork, C4 envelopes are the best size, whereas smaller C5 envelopes are better for products, cards or smaller documents. All our sizes fit Royal Mail standards.

Strengthen your branding with Cardboard Shipping Envelopes

Show your professional approach to business. Use personalised envelopes to deliver agreements, invoices, pictures, catalogues and other important documents with your own touch of style.

Soft or flat goods? We’ve got you covered!

Even the smallest, most simple cardboard mailer box or traditional postal packaging may be overkill for a small or flat item. In cases like this, custom envelopes are your ideal packaging solution. Bowties, documents, photos, postcards, or other small things all fit perfectly in a Cardboard Envelope. Add a little “thank you note” to your board backed envelopes and make your recipient’s day!

Recycled cardstock is the ideal material for your personalised envelopes if your brand is conscious about its environmental impact. Both styles – white and natural kraft – are fully recyclable. We use only water-based inks to make these ideal envelopes eco-friendly.

And here’s the best part – designing cardboard envelopes is super-easy in Packhelp’s online editor. You don’t have to be a designer to create the best custom envelope for your business. Add your company’s logo, create a memorable pattern or adjust the envelope design by adding text. Make the design all about your brand or address your customer by printing a witty text.

high Quality envelope printing that keeps your goods safe

Worry no more about the security of your items inside your custom cardboard envelope. Open the envelope with a simple peel-and-seal adhesive strip. Securing a gummed envelope takes seconds. Take the protective layer off, seal the envelope and send it. Our C5 and C4 envelopes are strong, durable and can be used for a variety of problems.

Small orders and bulk quantities

Let’s say you want a pile of 50 custom envelopes, ‘just in case’ you need them. You might also want 1000 personalised cardboard envelopes to invite guests to your company event or meet the requirements of your day-to-day operations. Depending on your needs, Packhelp’s envelope printing service can take orders from just 30 pieces to tens of thousands. You design your coloured envelope and we take care of the rest.
