Frequently Asked Questions (FAQ)
How should the portrait A5 and landscape A5 envelopes be applied practically in the office?
- The landscape A5 envelope is ideal for the accounting and cashier departments to gather bundles of small-scale retail invoices, cash receipts, or inventory inbound-outbound slips.
- The portrait A5 envelope features a slender vertical form factor, making it perfect for standing items such as commercial mailing envelopes, event access passes, business passports, or small office hardware like USB drives and charging cables.
Why are King Star's A4 and F4 envelope sizes larger than standard paper dimensions?
For instance, the actual dimensions of King Star's A4 envelope are 350 x 230 mm, while a standard A4 paper sheet measures roughly 297 x 210 mm. This safety margins are calculated by the manufacturer to allow personnel to store thick document sets with multiple sheets, texts attached with staples, or binder clips inside spacious rooms without cramping paper corners or tearing paper edges.
Should businesses prioritize placing orders in "Piece" units or by the "Pack"?
If the business needs uniform quantities to establish a large-scale office archiving system, selecting the "Pack of 10 pcs" or "Pack of 12 pcs" specification from the manufacturer helps the administrative department easily manage the supply inventory. Moreover, it ensures the best wholesale price benefits and optimizes procurement costs.
