This guide is for businesses and individuals seeking a professional, eco-friendly mailing solution. The key benefit is the combination of a premium, super white finish with sustainable recycled materials and a secure peel-and-seal closure. A potential caveat is that the C4 size might be larger than needed for standard letter mail. These C4 envelopes are made from high-quality recycled paper, are FSC certified, and feature a smooth, professional finish. They are compatible with digital and laser printers and utilize a convenient, tamper-proof peel-and-seal mechanism.

A C4 envelope (229 x 324 mm) is designed to hold an A4 sheet of paper without folding, or with a single fold. It's a larger size suitable for brochures, multiple documents, or items that require more space.
Yes, these envelopes are made from 100% recycled paper and are certified by the Forest Stewardship Council (FSC), ensuring they come from responsibly managed forests.
The peel and seal closure provides a strong, tamper-evident seal when applied correctly. It uses a strong adhesive strip that requires no moisture or heat, making it quick and secure for mailing.
Yes, these envelopes are compatible with both digital and laser printers. Ensure your printer can handle the C4 size and 120gsm paper weight.
The 120gsm (grams per square meter) weight indicates a thicker, more durable paper. This makes the envelope more robust, protecting your contents from damage during transit and giving a more premium feel.
Store the envelopes in a cool, dry place, away from direct sunlight and moisture, to preserve the paper quality and the effectiveness of the peel-and-seal adhesive.
The window dimensions are 40 x 105 mm, which is suitable for standard address labels or printed addresses.
Ensure the flap and the sealing surface are clean, dry, and free from dust or oils. Press firmly along the entire length of the seal for at least 10-15 seconds. Avoid sealing over rough or uneven surfaces.
Verify that the printer is set to handle C4 size and the 120gsm paper weight. Ensure envelopes are loaded correctly according to your printer's manual. Do not overfill the printer's feed tray. Print in smaller batches if necessary.
Check the storage conditions. If stored improperly (e.g., in a humid or very hot environment), the adhesive may degrade. Ensure the pack has not been open for an excessively long period.
Ensure you are using printer settings appropriate for envelopes. Some printers may have specific 'envelope' settings. Clean the printer's rollers and print head if smudging is persistent across multiple envelopes.
Setup: No setup is required for these envelopes beyond filling them with your documents and sealing them using the peel-and-seal strip. Ensure the surface area for the seal is clean and dry for optimal adhesion.
Compatibility: These envelopes are fully compatible with standard digital and laser printers for printing addresses or custom designs. Ensure your printer can handle C4 size paper and the 120gsm weight.
Care: Store envelopes in a cool, dry place away from direct sunlight and moisture to maintain the integrity of the paper and adhesive. Avoid prolonged exposure to extreme temperatures. For cleaning, use a dry or slightly damp cloth to wipe the exterior; avoid soaking the envelope.
