Business correspondence requires not only a neat appearance but also maximum efficiency and security. The C5 envelope with a window is one of the most popular choices for companies that value time-saving and professionalism when sending invoices, contracts, or official letters.
This envelope features a special peel and seal strip (HK type), which significantly speeds up the packing process. You no longer need to moisten the edge – just remove the protective strip and press down firmly. This is especially relevant when preparing large volumes of mail at once.
One of the key advantages of this model is the blue interior lining. This special printing layer ensures total confidentiality of the contents; even when held against strong light, the text remains unreadable. This is critical for sending confidential data or personal information.
The 45x90 mm window on the left side is designed to display the recipient's address. This eliminates the need to print labels or write addresses by hand – simply format your document so the address aligns with the window. The standard 80g/m² paper weight provides durability and ensures the envelope won't tear during transport.
This C5 envelope is an indispensable office tool for mass mailing. It is ideal for accounting departments, public institutions, and marketing teams. Due to its certified quality and reliable sealing mechanism, it is a cost-effective choice that ensures a flawless company image.
A C5 envelope is perfect for A5 sheets or a standard A4 sheet folded once in half.
Yes, the envelope fully complies with postal standards. The 80g paper is durable enough for safe transit.
The window is made of high-quality transparent film that remains clear, allowing automatic sorting machines to read the address easily.
