Some documents deserve just that little bit more protection than usual. Our Securitex brand tear-resistant envelopes were developed especially for important and confidential letters and documents. These high-quality envelopes are not only fully opaque, which conceals the contents from curious eyes, the sturdy 130 gsm envelopes are also tear-resistant and waterproof. This makes them ideal for mailing reports, contracts, diplomas and other privacy-sensitive documents. Securitex envelopes are available in various document sizes with or without a gusset. They also look very smart and professional thanks to the high-quality brilliant white outer layer that is a perfect surface for printing.
