Introduction to Woven Bags with PE Liners
Woven Bags with PE Liners are a versatile and durable solution designed to cater to various industrial packaging needs. These bags are constructed with polypropylene (PP) woven fabric, which provides strength and flexibility, and an inner PE liner that ensures moisture resistance and protection from external contaminants. Such features make these bags ideal for packaging products ranging from chemicals and fertilizers to food and agricultural goods.
The PE liner can be customized for different thicknesses, textures, and sealing properties, making it a vital component in specialized applications. Some of the common variations include Aluminum Liner Bags, which enhance barrier properties, and Liner PE Bags that are used for high-moisture or sensitive products.
Product Specifications and Advantages
Below is a table detailing the key parameters of Woven Bags with PE Liners:

Historical Background: The Evolution of Woven Bags
Roots in Textile and Plastics Revolution
The origin of woven bags dates back to the advancements in the textile industry during the early 20th century. With the advent of synthetic fibers, particularly polypropylene and polyethylene, the plastic revolution of the mid-1900s reshaped industrial packaging. Initially developed for heavy-duty applications, woven bags with liners emerged as a superior alternative to jute sacks and multi-layer paper bags due to their cost-efficiency, lightweight nature, and reusability.
Expansion into Diverse Applications
In the latter half of the 20th century, the versatility of Woven Bags with PE Liners allowed them to penetrate new markets. The agricultural sector adopted these bags for grain storage, while the chemical and construction industries utilized them for packaging powders and granules. Over time, customized options such as Aluminum Liner Bags and multi-wall bags were introduced, catering to niche requirements like high-barrier properties for sensitive goods.
The Rise of Woven Bags in China
China’s role in the global woven bag industry has been significant, especially in recent decades. Here’s how woven bags have evolved and thrived in the Chinese market:
- Pioneering Efforts by Wenzhou Merchants
