PE film is widely used in many different areas of life, bringing many benefits to users. In the packaging industry, PE film is used to coat the surface of the packaging and then protect the product from the effects of the environment.
So what exactly is PE film? Besides coating the packaging film, what is the product used for? Readers, please join us to find out the answer in this article.
What do you know about PE films?
PE film, also known as shrink film or PE Stretch film. PE stands for polyethylene, which is prepared by the polymerization of ethylene monomers (C2H4) under suitable temperature and pressure conditions.
PE film is produced from virgin PE resin, which is made by melting at a suitable temperature in an extruder. Then the manufacturer proceeds to put the mixture into the injection mold and cool it down, from which the PE film is produced.
PE plastic resins are put into the extruder, the temperature is raised to make the plastic granules melt, brought to the shaping mold, and then rolled in. Manufacturers easily adjust the thickness of the film by changing the speed of stretching during the passage of the forming.
General characteristics of PE film
Polyethylene film is white, slightly transparent, odorless, and flexible. In particular, PE film does not conduct electricity and heat. Moreover, the film is impermeable to water, O2, CO2, NO2... Thanks to its high durability, elasticity, and good adhesion, the product is widely used in many areas of life.
Besides physical properties, PE films also have chemical properties. Polyethylene film at normal temperature does not react with any solvents or solutions. If the temperature is above 70 degrees Celsius, the PE film is poorly soluble in mineral oil, xylene, etc. In particular, this plastic film is not dissolved in water.
Common types of PE films
In daily life, the closest PE film is food wrap. PE film helps preserve food from dirt, and insects, and keeps food fresher for longer.
PE film has many uses not only in the manufacturing sector but also in some cases of daily life. PE film is used to wrap electrical wires, wrap goods, and bags, ... or used as a rain screen, and in the manufacture of equipment for chemical production. The common types of Polyethylene used today can be mentioned as below:
Industrial PE film for wrapping machine
This is a good quality machine-wrapped shrink film, tested for durability, tearing, and perforation. When performing the wrapping, the user is not afraid of being interrupted, operating smoothly.
PE shrink film used to wrap the machine can wrap bulky products, ensuring the safety of goods. The PE film used to wrap the machine usually has the following indicators:
-
Weight from 3.8kg, 5kg, 10kg, and 15kg
-
Core diameter is 7.6cm or 3” inch
-
The usual thickness is 20-23micron
PE film for hand wrapping
The hand-wrapping film is used to protect many different products, most of which are small and light in size. Pe stretch films are widely used in industries such as garments, seafood, etc with the following specifications:
-
Weight from 1.4 to 4 kg.
-
Thickness from 15mic-19mic, or 25mic.
Application of PE film in today's life
Polyethylene film is used in many different aspects of life, and possesses many preeminent features and safety for users and goods.
Application of PE film in the production of jumbo bags
The application of PE film in the production of FIBC bags helps to preserve the inner products from water or leaking out of the bags. For products that are not exposed to water or wet environments, coated PP bulk bags are the right solution.
PE film in food processing
Possessing the feature of being thin, non-toxic and easy to use, PE shrink film is used by housewives to wrap meat or some other kinds of food. When making cakes, PE film is used to cover the baking tray, waiting for the dough to ferment. At the same time, safe PE food wrap is used to cover processed food to protect food from flies or other insects.
PE film in agriculture
In agriculture, PE shrink film is used to wrap and preserve feed for livestock and poultry. At the same time, PE agricultural film is a mulch layer used to wrap agricultural products, helping to prevent the soil from being affected by pests and diseases, affecting crop quality.
