When people think of "plastic bags", what usually comes to mind are the thin, transparent shopping bags in supermarkets. However, the world of plastic packaging actually falls into two main categories: plastic woven bags and plastic film bags.
Although both types of bags are made of plastic, they have essential differences in terms of materials, structure and performance. Ordinary plastic bags are mostly made of polyethylene (PE) film, while woven bags mainly use raw materials such as polypropylene (PP) or high-density polyethylene (HDPE).
In terms of load-bearing capacity, the gap between the two is even more obvious. The medium-sized bags of ordinary plastic film bags can generally carry 1 to 10 kilograms, and the heavy-duty bags can only carry 10 to 30 kilograms. In contrast, the medium-sized bags of PP woven bags can directly carry 25 to 50 kilograms, and the heavy-duty bags can carry even more, up to 50 to 100 kilograms.
