White envelope

Start with document size and choose between common formats like A4 (about 35x25 cm) and DL or similar sizes. For bulk mailing, packs of 50 or 150 are convenient, while individual packs like 10 slips are ideal for lighter, occasional use. Consider the paper weight, with 100 GSM envelopes offering more durability than lighter options. Matching the envelope size to your documents ensures secure, flat transport and a neat presentation.

Self-adhesive envelopes provide a built-in seal that eliminates licking or moisture and offers quick, secure closure, ideal for busy mailing tasks. Standard envelopes require moisture to seal and may rely on a separate adhesive strip or flap. If security is a priority, self-seal options paired with strong paper are useful, while standard seals suffice for everyday, non-sensitive mail.

Consider your typical mailing frequency: 50- or 50-envelope packs work well for regular correspondence, while a 150-envelope box suits higher-volume tasks. For lighter, occasional use, smaller packs like 10 envelopes provide flexibility without excess waste. Choosing a mix of pack sizes can cover both daily and occasional bigger mailing jobs efficiently.

Yes. Security self-seal envelopes come with a secure pattern and strong self-seal closure to protect contents during transit, making them suitable for important documents. For professional presentations, DL and C4 formats in white deliver a clean, official look, especially when combined with robust 100 GSM or higher paper stock that resists creasing.

Common options include A4 at 35x25 cm, DL size, and C4 formats. Paper weights vary from around 80 GSM to 100 GSM, with 100 GSM offering enhanced durability for everyday documents. Self-adhesive variants typically emphasize secure sealing and ease of use, while standard envelopes emphasize affordability and wide availability.
