Cardboard envelopes and mailers

Post different sized products with our versatile cardboard envelopes and mailers

At RAJA, we have plenty of ways to help you protect your products while they’re in the post. A simple and effective way to offer some extra protection when your items are in transit, helping to ensure they arrive to your customers and clients looking as good as when they left your workplace. Stocking your business with small cardboard envelopes is an economical way to provide a snug fit for letters and thicker items like magazines, as they are more resistant to punctures and the frequent bumps normally found in postal packaging.

For products, like books or DVDs, flat cardboard envelopes are the perfect choice for your postal packaging. Our sturdy envelopes can also expand to fit different sizes and shapes, making them the ideal choice if you’re sending items with various weights. Made from solid 500 – 550 gsm board, these envelopes provide a snug fit for their contents.

If you’re an online or an e-commerce business, and you’re selling goods that aren’t a standard shape, then our cardboard mailers are a useful alternative. A more environmentally friendly option than polythene options, our brown paper mailing bags are ideal for sending out bulkier products, like clothing. Our e-commerce Kraft paper mailing bags are perfect for sending fabrics through the post, and are able to be recycled once they reach their destination. Utilising cardboard mailing envelopes gives you the versatility to send both flat and unconventional shapes.

Forming a comprehensive part of the RAJA envelope range, our selection of flat cardboard mailers and envelopes, as well as our mailing bags, are available in plenty of the popular sizes that are standard to the Royal Mail.For a more premium feel with a distinctive appearance, our white cardboard mailer envelopes can give a professional appearance to your products.

Can I recycle my postage material?

At RAJA, we’re always driving to help businesses become eco-responsible. One of the key advantages to stocking cardboard shipping envelopes in your workplace is that they are an eco-friendly alternative to polythene, or envelopes with windows. The entirety of our range is recyclable. So you can secure your contents while doing your part for the environment. Check out our blog for more information on which envelopes and mailing bags are the most eco-friendly.

You can count on us!

Our specialists are on hand to help you navigate our products so you can have the best one for your business. With our wide range of white and brown cardboard envelopes and mailers, RAJA can help your products arrive at their destination safely and securely.
