Envelope AirPro Nr.3 170x225 mm brown outer, 150x215 mm inner

AirPro Envelope Nr.3 170x225 mm brown outer, 150x215 mm inner is a mailing envelope designed for everyday postal and office use. The envelope features a brown exterior and an inner usable area that accommodates standard letters, documents and small flat items. It is suitable for routine correspondence and simple storage tasks where protection from dirt and light handling is required.

Advantages

The envelope provides a compact solution with clear outer dimensions for easy sorting and postage calculation. Its inner usable area leaves sufficient margin for contents while minimizing excess bulk. The brown exterior offers a neutral appearance that hides minor marks and is compatible with address labelling and ink printing. The construction supports standard handling by postal services and office staff.

Suitable for

• Standard letters and folded A4 documents
• Printed invoices, receipts and notices
• Small flat items such as photos, index cards or thin brochures
• Office filing and short-term document storage

Key specifications

• Outer dimensions: 170 × 225 mm
• Inner usable area: 150 × 215 mm
• Color: brown exterior
• Format: rectangular mailing envelope for flat contents
• Closure type: manual flap (suitable for adhesive or tape sealing)

How to use

Insert folded or flat documents into the envelope ensuring they fit within the inner usable area. Align the content so addresses or document edges are positioned away from the flap to allow secure closure. Seal the flap using the recommended adhesive, gummed strip or tape. Print or write the recipient address on the front surface, or apply a pre-printed label in a clear, readable position. For postal dispatch, check postage requirements and handling instructions prior to sending.

Usage recommendations

For best results when printing addresses directly on the envelope, test print settings on a sample to confirm legibility. Avoid overfilling beyond the inner usable area to prevent tearing or damage during handling. Store unused envelopes flat in a dry environment to preserve shape and sealing performance.
