Envelopes & Packing Material

Mailing and Packing Made Simple

Whether you mail invoices, send samples or wrap goods for pickup, this category gathers the essentials that keep your packing bench moving. We focus on dependable stocks that feed smoothly through office devices, seal securely and protect contents in transit.

What You’ll Find Here

• Business Envelopes – White and manila in C4 (A4 flat), C5 (A5 or A4 folded once) and DL (A4 folded into thirds), available in window and non-window styles with gummed, self-seal or peel & seal closures.
• Bubble Cushion Envelopes – Padded mailers that help absorb knocks for small products, gadgets and literature packs.
• Packing Papers – Kraft/brown sheets for wrapping and void-fill, sugar/butter/mahjong paper for interleaving, lining and general protection, plus cut sheets for large-format wrapping jobs.

How to Choose

• Size & fold – Use C4 when documents cannot be folded, C5 for A4→A5, and DL for A4→DL letters.
• Seal type – Gummed is economical; self-seal speeds manual jobs; peel & seal gives the strongest, longest-life bond.
• Window vs non-window – Window relies on the address printed on the letter; non-window suits handwriting or label application.
• Protection – Use bubble mailers or heavier paper when the contents need cushioning or scuff resistance.

Usage Tips

• Match envelope size to fold style to prevent bulky edges and sorter jams.
• Apply clear addressing with A4 sheet labels or choose window envelopes to show printed addresses.
• For certificates and items that must remain flat, choose C4 and a heavier gsm.
• Store paper and envelopes flat, clean and dry to maintain sealing strength and print quality.
• For any direct-contact uses (e.g., food wrapping), always check the individual product notes and local requirements.

FAQ

What’s the difference between gummed, self-seal and peel & seal?

When should I use a window envelope?

Choose window when the address is printed on the letter and positioned to show through; choose non-window for handwriting or label application.
