PE bag is a plastic bag made of PE (polyethylene), which is a very common thing in our daily life and can be seen everywhere. And PE bags can be divided into high-pressure PE bags and low-pressure PE bags, so what is the difference between the two? Next, let's discuss it in detail.
High-pressure PE bags are made of low-density polyethylene (LDPE), which is obtained through reaction in a high-pressure environment; The low-pressure PE bag is made of high-density polyethylene (HDPE) obtained through polymerization reaction in a low-pressure environment.
Due to its low density, high-pressure PE bags have a soft texture, good ductility, and impact resistance, but are prone to cracking; Low pressure PE bags have a hard texture due to their high density, good hand feel, and are not easily stretchable but have good stability, as well as good heat resistance and mechanical strength.
Due to its softness, high-pressure PE bags are generally thicker and require more raw materials, which leads to a relatively higher price.
High pressure PE bags are generally used for lightweight packaging, while low pressure PE bags are generally used for heavy packaging.
