PE (polyethylene) films, especially low-density polyethylene (LDPE) films and high-density polyethylene (HDPE) films, occupy a pivotal position in the field of plastic packaging films. These two films have become popular choices in the market due to their unique properties and wide application areas.
LDPE film is known for its excellent toughness, moisture resistance and heat sealing properties. It is often used as the inner film of composite flexible packaging materials, as well as packaging occasions that need to withstand certain stretching and twisting. The flexibility and tear resistance of LDPE film enable it to withstand large deformation and impact during the packaging process, thereby ensuring the integrity and aesthetics of the packaging. At the same time, LDPE film also has good printability and heat sealing properties, making it easy to make labels and packaging bags of various shapes and sizes.
HDPE film is favored for its translucent appearance, good strength and toughness, and excellent opening properties. It is widely used in shopping bags, garbage bags, fruit packaging bags, and various food packaging bags. HDPE film has good heat resistance and is particularly suitable for the heat sealing layer of cooking bags, which can maintain the integrity and sealing of packaging at high temperatures. In addition, HDPE film also has good chemical resistance and can withstand the erosion of various chemicals to ensure the safety and stability of the products in the package.
In recent years, the rise of linear low-density polyethylene (LLDPE) film has further enriched the varieties and applications of PE film. LLDPE film has higher tensile and impact strength, as well as excellent tear and puncture resistance. This makes it show great application potential in the packaging of various daily necessities, frozen foods, and the manufacture of heavy packaging bags and garbage bags.
For merchants, it is crucial to understand these diverse varieties and wide applications of PE films. It can not only help merchants better choose film materials that meet customer needs, improve the quality and efficiency of product packaging, but also play an important role in innovative packaging design and optimizing production costs. By rationally selecting and applying PE films, merchants can reduce costs, improve product quality, and meet consumers’ demand for environmentally friendly and sustainable packaging.
