In the packaging and logistics industry, heavy-duty shipping bags and standard polyethylene bags are two common packaging materials. Although they are both made of polyethylene, they have significant differences in design, strength, and load-bearing capacity due to their different uses. Heavy-duty shipping bags are usually used to carry heavy objects and bulk commodities, while standard polyethylene bags are more suitable for packaging lightweight items. Understanding the difference between these two bags is crucial to choosing the right packaging material.

1. Material strength and thickness
Heavy-duty shipping bags are usually made of thicker and stronger polyethylene materials, and their thickness is generally larger, usually above 0.1 mm. In contrast, standard polyethylene bags are usually thinner, about 0.03 mm to 0.08 mm. The thickness of heavy-duty shipping bags enables them to withstand heavier weights and high pressure during transportation, while standard polyethylene bags are more used to package lightweight items and are suitable for daily transportation and storage.

2. Load-bearing capacity
Because heavy-duty shipping bags are made of thicker polyethylene materials, they have a higher load-bearing capacity and can carry heavy objects. Typically, these bags are designed to transport heavy items such as sand, ore, and building materials. Standard polyethylene bags are more used to pack light items such as clothing, food, or small parts, and cannot withstand heavy weight.

3. Usage scenarios
Heavy-duty transport bags are generally used in industries such as industry, construction, and agriculture, especially when bulk items need to be carried, such as transporting bulk materials, chemicals, agricultural products, etc. Standard polyethylene bags are widely used in daily life, such as food packaging, clothing storage, shopping bags, etc., mainly to meet the needs of light packaging.

4. Design and closure method
Heavy-duty transport bags are usually designed as large square or cubic bags, suitable for carrying large quantities of items and maintaining a stable shape during transportation. They are usually equipped with reinforced closure systems, such as ropes, cable ties, or stronger heat-sealed seams to ensure the stability and safety of the bags during long-distance transportation. The design of standard polyethylene bags is simpler, usually with a simple folding closure, which is convenient to use.

5. Durability and tear resistance
Because heavy-duty transport bags need to withstand greater weight and pressure from the external environment, they have stronger tear resistance, which can effectively avoid rupture or damage during transportation. Standard polyethylene bags have weak tear resistance and are suitable for packaging lightweight items, but they are prone to rupture when subjected to greater pressure.

6. Cost
Because heavy-duty shipping bags use more and stronger materials, the production cost is relatively high. In contrast, standard polyethylene bags have lower production costs and are suitable for daily lightweight packaging needs.

Heavy-duty shipping bags and standard polyethylene bags are significantly different in terms of carrying capacity, material strength, and usage scenarios. Heavy-duty shipping bags are suitable for the transportation of heavy objects and bulk commodities, while standard Heavy-duty PE Tubular bags are more suitable for daily lightweight packaging.
