1. Material Characteristics: The core material of non-woven bags is non-woven fabric, also known as nonwoven cloth, a new type of fiber material directly formed from fibers through mechanical, chemical, or thermal bonding. Compared to traditional textiles, non-woven fabrics do not require complex processes such as spinning and weaving, resulting in simpler production processes and lower costs. They also possess good breathability, softness, and water absorption. The material is environmentally friendly and biodegradable, aligning with modern green consumption concepts.
2. Physical Properties
Load-bearing capacity: The load-bearing capacity of non-woven bags varies depending on thickness and manufacturing process. Generally, ordinary non-woven bags can bear a weight of 5-10 kg, while thicker or specially treated products can bear over 20 kg. Some customized products can even meet higher load-bearing requirements.
Durability: Non-woven bags have good tear resistance and abrasion resistance, with a lifespan of several years under normal use. Some products, through the addition of anti-aging agents or special processing, can extend their lifespan to 10 years. Waterproofing: Ordinary non-woven bags have poor waterproofing, but their waterproofing performance can be improved through lamination processes (such as PE film), making them suitable for humid environments.
3. Appearance and Design
Colors and Patterns: The colors of non-woven bags can be customized to meet specific needs. Common colors include basic colors such as white, black, and red. Colorful patterns or brand logos can also be achieved through printing processes.
Shapes and Sizes: Various shapes are available, including tote bags, backpacks, and flat bags; sizes are flexible and can be customized to suit different uses, ranging from A4 document bags to large shopping bags.
Printing Processes: Supports various processes such as gravure printing, offset printing, and heat transfer printing. The printing results are clear and vibrant, suitable for corporate promotion or personalized customization.
4. Environmental Protection and Sustainability: Environmental friendliness is one of the core advantages of non-woven bags. Their raw materials (such as polypropylene fiber) are recyclable, and the production process is energy-efficient and low-polluting. After disposal, they can be naturally degraded or recycled, reducing the environmental burden and meeting global requirements for plastic pollution control.
5. Application Scenarios
Retail Industry: As a shopping bag to replace traditional plastic bags, enhancing brand image.
Advertising and Promotion: Customized bags with company logos or slogans for promotional gifts or giveaways.
Industrial Packaging: Used for inner packaging or transportation protection of products, such as electronic components and food.
Everyday Use: Such as storage bags, document bags, gift bags, etc.
6. Industry Standards and Quality Certifications
Non-woven bags must comply with environmental standards (such as the EU RoHS Directive) and food contact safety standards (if used for food packaging). Some high-end products have passed international certifications such as SGS and ISO, ensuring reliable quality.
7. Cost and Cost-Effectiveness
The price of non-woven bags is affected by factors such as material thickness, size, and printing process. The unit price of ordinary shopping bags is usually between 0.5-3 yuan, while customized products (such as thickened or special-shaped bags) may be more expensive. In the long run, their durability and environmental friendliness make their overall cost lower than that of disposable plastic bags.
