HERLITZ C4 brown paper envelopes (229 x 324 mm) are designed to hold unfolded A4 documents and correspondence. Each envelope is made from 90 g/m² recycled paper with a plain brown finish and a gummed flap for secure closure. The pack contains 10 envelopes, shrink-wrapped for convenient storage and transport. The material carries the Blue Angel environmental certification, indicating a reduced environmental impact compared with conventional paper products.

Advantages

How to use

Insert unfolded A4 documents into the envelope so they lie flat and align with the edges. Moisten the gummed flap and press firmly along the seal to ensure a secure closure. For mailing, affix postage and any required labels or address information to the front of the plain surface. When storing documents, write or apply a label on the exterior to identify contents before sealing.

Usage recommendations

For reliable postage handling, avoid overfilling the envelope; keep internal contents within the dimensions to prevent stress on the gummed seal. Use a damp sponge or sealing gum for consistent adhesion and allow a moment for the glue to set before stacking. For long-term archiving, store sealed envelopes in a dry, cool environment away from direct sunlight to preserve paper quality.
