Outstanding Features of Thien Long Plastic Button Envelope
High-Quality Virgin PP Plastic Material for Safety
The product is made from a premium PP plastic source, featuring soft, flexible, and resilient characteristics that provide excellent impact resistance. This material not only protects the envelope against water and dust accumulation effectively but also ensures high durability during continuous office use. The colorless (transparent) plastic helps users quickly identify internal document titles without opening the flap.
Secure Plastic Snap Button Design
The envelope utilizes a durable plastic press stud closure mechanism, firmly fixed using modern heat-sealing technology. The snap joint features standard tightness, keeping the fold-over flap secured to the body to protect documents from falling out or being misplaced while employees are on the move or traveling for business.

Frequently Asked Questions (FAQ)
Which plastic thickness should I choose for documents that are circulated frequently?
For documents that need to be retrieved and opened continuously or carried out to meet clients, businesses should prioritize selecting product codes with greater thickness, such as 0.16 mm (FO-CBF04) or 0.18 mm (FO-CBF05), to ensure the envelope shape remains sturdy and offers better load-bearing capacity.
Why is Thien Long's A4 envelope size larger than standard A4 paper dimensions?
The actual dimensions of Thien Long's landscape A4 envelope are 340 x 240 mm, whereas standard A4 paper measures roughly 297 x 210 mm. This intentional difference allows office staff to easily slide in thick document bundles with multiple sheets or documents attached with staples without cramping or tearing the paper edges.
Which packaging specification should businesses select when buying in large quantities?
For convenience in inventory counting, consumable supply management, and to secure the best wholesale price policies from us, corporate purchasing departments should place orders according to the "Pack of 10 pcs" or "Pack of 12 pcs" specification corresponding to each product code.
