I. Why Have Plastic Bags Become the Mainstream Packaging Method?

Plastic bags have maintained a significant position in the global packaging market for a long time, thanks to their inherent advantages.

1. Excellent Protective Performance
   Plastic materials are waterproof, moisture-proof, and dust-proof, effectively protecting products.
   For example:

   • Garment bags prevent clothes from getting damp or dusty.

   • Courier bags ensure the safe transport of goods.

   • Industrial bags reduce the impact of external environmental factors on products.
     For products requiring long-distance transportation, plastic bags are an efficient and practical packaging option.

2. Lightweight and Reduced Transport Costs
   Compared to cardboard boxes, glass, or metal packaging, plastic bags are lighter and take up less space. This is especially important in cross-border e-commerce and international logistics, where packaging weight directly affects shipping costs. Using lightweight plastic packaging can:

   • Lower logistics expenses.

   • Improve warehousing efficiency.

   • Reduce storage space occupancy.

3. Flexible Customization Capabilities
   Plastic bags have good processing properties and can be customized to meet business needs. Common customization options include:

   • Printing brand logos.

     For businesses aiming to enhance their brand image, custom plastic bags serve not only a protective function but also as a form of brand promotion.
