Import A4 File Folder With 3 Holes And Card Pocket — Buy in Bulk from Supplier in China

The A4 file folder from Yiwu Joinus Stationery Co., Ltd. is a three-hole punched design with an integrated card pocket, built for A4 document storage. It measures 210 mm by 297 mm to fit standard international paper sizes, with the holes spaced at 80 mm intervals, a typical configuration for European and Asian binders. The folder’s card pocket is positioned on the front cover for quick identification, and the material is a standard 250 GSM manila or polypropylene, selected for durability in frequent use.

This variant uses a reinforced spine and rounded corners to resist bending and tearing, a common upgrade for folders intended for heavy office rotation. The three-hole punch aligns with ISO 838 standard spacing, ensuring compatibility with most ring binders. Manila folders in this category typically meet a bursting strength of 1.2 kPa, while polypropylene versions offer water resistance and a smoother surface for writing. The card pocket is usually 50 mm by 70 mm, sized for business cards or labels.

Professionals in legal, academic, and corporate environments use these folders to organise reports, contracts, and presentation materials. They are also adopted in educational settings for student assignments and administrative records. The folder’s lightweight design, often under 100 grams, makes it practical for carrying in briefcases or backpacks. Buyers sourcing from Yiwu Joinus Stationery Co., Ltd. should confirm binder compatibility, material type, and colour options as these can vary by production batch.
