What are the advantages of PE film?

PE film is the most popular and commonly used plastic in the world, used in shopping bags, toys and shampoo bottles. The annual production of this material exceeds 100 million tons of resin, accounting for 34% of the plastics market. PE film has many advantages, which is why it has been used to manufacture many products for many years.

Why choose PE film?

There are many types of plastic films, and they are usually used for packaging, coating, and protecting items. There are several kinds of materials, such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS) and other materials. Among them, PE film is made of polyethylene. It is made of raw materials, and it has obvious advantages compared with other films to choose PE film. The following will show you why you should choose PE film.

What are the benefits of PE film?

Polyethylene film is referred to as PE film, which is colorless, tasteless, non-toxic, odorless, and translucent. Excellent mechanical strength, dielectric properties, moisture resistance to humid environments, can withstand low temperatures to minus 70 and can still maintain flexibility and chemical stability in low temperature environments. It is insoluble in most solvents at low temperature, and does not react with moisture, grease, chemical compounds, etc. Compared with other films under the same thickness, PE film has lower transparency and lower flexibility, and the biggest point is that it is environmentally friendly and non-toxic.

l PE film burns into carbon dioxide and water without residue. In this process, no toxic smoke or gas will be produced, and no cinder will be produced

l PE film does not contain plasticizers and heavy metals. They are harmless to physiology

l No peculiar smell or waste water will be produced during the production of PE film

What are the advantages of PE film in the application field?

PE film can generally be divided into three types. 1. Low-density polyethylene film (LDPE) 2. Medium-density polyethylene (MDPE) 3. High-density polyethylene (HDPE), depending on the manufacturing methods and control methods used by different manufacturers. Based on the above advantages and unique properties, PE film is widely used in many fields, such as food, medicine, daily chemical, industrial and other fields.

①　PE film has many useful characteristics, making it suitable for many applications. It has low strength and hardness, but is very ductile and has good impact strength; it will stretch rather than break.

②　Polyethylene is waterproof and durable, so compared to other polymers, polyethylene is more durable when exposed to elements.

③　PE film is a good electrical insulator, with electrical tree resistance, but it will be charged with static electricity. Adding an antistatic agent will prevent this.

④　Depending on the thickness of the PE film, it can be almost transparent to opaque. The transparency of low-density polyethylene (PE) makes it suitable for packaging.

⑤　PE film as HDPE can be recycled into other products, which is more cost-effective than making new products with new plastics.

⑥　For medium to high density polyethylene, the melting point ranges from 120 to 180 degrees Celsius; for low density polyethylene, the melting point ranges from 105 to 115 degrees Celsius. Good heat resistance allows it to be used at high and low temperatures.

Different PE film application fields require different functions of PE film. For example, in the food field, the most commonly used performance requirements are hygiene, non-toxicity and safety. Industrial performance requires puncture resistance and excellent tear resistance, so PE film came into being . There are more than a dozen functional products produced by PE film as the main body, but there is no need to be confused. The essential material is still PE film as the main material, usually PE protective film and PE composite film.
