Use Cases & File Specs
Use Cases & File Specs
Some documents deserve to travel flat. Large envelopes in C4 size (229×324mm) hold A4 sheets without folding, so contracts, tender submissions, and official correspondence arrive with clean pages and no creases. For offices where paperwork is the product — legal, finance, government, construction, and procurement teams — ZprintPro large envelopes are the office essential that keeps multi-page bundles presentable end to end.
Contract-heavy businesses mail signed agreements, amendments, and board packs in volume, and the heavier stock carries the extra pages comfortably. Tender and bid teams use the same envelopes to present sealed submissions with a professional, tamper-evident feel, while HR and finance departments standardize on them for letters, payroll packs, and employee documentation.
Because the format is a workhorse, consistency pays: match the envelope colorway to your folders and letterhead so the whole document set reads as one system. The glue type is selectable to suit your sealing workflow, and if confidentiality matters, an inner print option can be discussed so sensitive material stays discreet.
Stock is primarily 100–120g book paper, chosen to hold multiple pages without sagging, with C4 (229×324mm) as the standard size. Printing spans single-color to full four-color, with optional self-adhesive seals and windows. We also advise on thickness for machine sealing, so automated stuffing lines run without jams.
Pricing is HK$0.60–3.40 per piece from a 100-piece minimum, with free US shipping over $100 and DHL Express or FedEx in 3–5 days to the USA and 2–4 days to Japan, plus worldwide delivery to 50+ countries. Same-day file confirmation and ISO 9001 certified production keep office workflows predictable.
