Envelope, File Folder

Updated: 2026-07-22

Overview

Envelopes and file folders are fundamental office supplies used for mailing and organizing documents. Envelopes are designed to securely hold letters or papers, often featuring adhesive seals. File folders, on the other hand, are used for categorizing and storing documents in filing systems. Both products are typically made from paper, though plastic or reinforced materials are also available for added durability. Their designs vary based on intended use, such as windowed envelopes for addresses or tabbed folders for easy identification.

Envelopes come in various styles, including standard, windowed, and padded options. Windowed envelopes have a transparent section to display addresses, while padded envelopes offer extra protection for fragile contents. File folders often include tabs for labeling and may feature reinforced edges for longevity. Customization is a key feature, with options for printing logos, colors, or specific sizes. Eco-friendly materials, such as recycled paper, are increasingly popular among businesses aiming for sustainability.

Main Uses

Envelopes are primarily used for mailing letters, invoices, and other documents. They are indispensable in postal services, offices, and e-commerce for shipping small items. File folders are essential for organizing paperwork in offices, schools, and archives, helping maintain efficient document management systems. In B2B contexts, bulk procurement of these supplies is common for corporate mailings, record-keeping, and promotional campaigns. Custom-printed envelopes and folders also serve branding purposes.

Culture and Development

Envelopes have a long history, dating back to ancient civilizations like Mesopotamia, where clay envelopes were used. Modern paper envelopes became widespread in the 19th century with the advent of mass postal systems. File folders emerged alongside the growth of bureaucratic and office cultures, evolving to meet organizational needs. Today, digitalization has reduced some demand for physical envelopes and folders, but they remain vital for legal, archival, and certain business communications. Innovations include eco-friendly materials and smart folders with RFID tags.

B2B Procurement Guide

For B2B buyers, key considerations include volume discounts, customization options, and supplier reliability. Bulk purchases often reduce per-unit costs, making it economical for large organizations. Custom printing for branding requires choosing suppliers with high-quality printing capabilities. Evaluate material quality, especially for folders that undergo frequent use. Eco-friendly options, such as recycled paper or biodegradable plastics, are increasingly demanded. Lead times and MOQs (minimum order quantities) should align with business needs.
