PP, HM, and LDPE bags are types of plastic bags commonly used for packaging various items. Here's a brief description of each:

1. 1. PP Bags (Polypropylene Bags):

   • - Made from polypropylene, a thermoplastic polymer.
   • - Known for their strength, durability, and resistance to moisture and chemicals.
   • - Often used for packaging food items, textiles, grains, and industrial products.
   • - Can be woven or non-woven, depending on the specific application.

2. 2. HM Bags (High-Density Polyethylene Bags):

   • - Made from high-density polyethylene (HDPE), a strong and rigid plastic.
   • - Offers excellent strength-to-density ratio, making it suitable for carrying heavy items.
   • - Resistant to tearing, puncturing, and moisture.
   • - Commonly used for grocery bags, trash bags, packaging materials, and agricultural purposes.

3. 3. LDPE Bags (Low-Density Polyethylene Bags):

   • - Made from low-density polyethylene (LDPE), a flexible and lightweight plastic.
   • - Known for its toughness, flexibility, and transparency.
   • - Offers good resistance to moisture, chemicals, and punctures.
   • - Widely used for packaging food, pharmaceuticals, clothing, and various consumer goods.
