As the name suggests, a supermarket advertising bag is a customized bag produced by plastic manufacturers for businesses in the retail industry, serving the purpose of promotion and publicity. Also known as supermarket shopping bags, they are widely used in daily life—but how much do you know about their materials?

Supermarket advertising bags typically come in two types of materials: high-pressure polyethylene (HDPE) bags and low-pressure polyethylene (LDPE) bags. Both belong to the PE (polyethylene) material category but have distinct advantages and disadvantages.

HDPE bags are commonly used for high-grade shopping tote bags, gift tote bags, and finished product bags required for industrial packaging. This is because HDPE bags feel soft and glossy on the surface, and more importantly, they are durable enough to carry objects of a certain weight. LDPE bags, on the other hand, are considered mid-to-low-grade supermarket advertising bags, frequently used in shopping malls, supermarkets, and the food industry. They are also the material for takeout bags used in restaurant kitchens and vest-style bags sold at supermarkets. Key features of LDPE bags include excellent tensile resistance, high hardness, resistance to deformation from occasional tearing, and protection against punctures by blunt objects.

How can you distinguish between these two types of plastic supermarket advertising bags in daily life? A simple method is to tear the bag forcefully: if there is a white mark at the tear, it is an LDPE bag; otherwise, it is an HDPE bag. During the test, you will also notice a clear difference—HDPE bags offer greater resistance when being torn.
