What is PE packaging film?

PE (Polyethylene) is a type of polymer, or plastic material, formed from ethylene units linked together through non-polar hydrocarbon bonds. This polymer has flexible properties and excellent recyclability, making it a popular choice in the industrial and packaging sectors.

PE film (PE Stretch Film) is a form of PE plastic. It is produced by melting the PE plastic pellets at the appropriate temperature in an extruder. Then, the molten PE plastic is shaped and cooled through a production process. PE film has the ability to stretch and maintain its shape, and it is often used to wrap and protect goods and food from external environmental influences.

The production process of PE packaging film

The most common method for producing PE film is using an extrusion machine. Specifically, the production steps may include:

  • Melting PE pellets: PE plastic pellets are fed into the extruder and melted at a temperature of about 120°C.
  • Shaping and cooling: The molten PE plastic is then passed into a mold to shape and adjust the size. Afterward, the PE film is cooled and rolled onto product rolls.
  • Rolling into finished products: Once the PE film has been shaped and cooled, it is rolled into rolls that can be used.

What are the characteristics of PE film?

Physical properties:

  • PE film is typically transparent or colorless and has no odor.
  • It is non-conductive of heat and electricity.
  • It has high strength and good stretchability (up to 300%), making it easy to wrap around various shapes.
  • PE film is waterproof and resistant to oils and greases, preventing the infiltration of air and other harmful agents.
  • The melting point of PE is high (around 120°C), while its glass transition temperature is low (-100°C), which gives it stability in various temperature conditions.

PE film has become an essential part of the packaging and transportation industry due to its outstanding properties and flexibility in protecting goods and food.

Chemical properties:

  • At room temperature, PE film does not react with many solvents, dyes, acids, alkalis, and bromine water. This makes PE film a suitable material for preserving and packaging various types of food and goods that need protection from external factors.
  • At high temperatures (above 70°C), PE film may have limited solubility in some solvents like mineral oil, turpentine, xylene, and toluene. This property can be used in some special applications but is not commonly encountered in normal conditions.
  • PE film is insoluble in water, fatty alcohols, and essential oils at any temperature, allowing it to maintain stability in humid and temperature-variable environments.
