What is PE wrapping film?
PE film, also known as PE wrap, is a thin elastic-plastic material used to wrap around products, boxes, crates, and pallets. It should be noted that the higher the elastic recovery rate, the better the membrane. The primary purpose of PE film is to stack products onto pallets and hold them correctly and securely during transit.
PE film is one of the widely used and available products, becoming the first choice of many users in recent years to pack all kinds of products, goods, and items. , protect components and machines from dust and agents that affect product quality.
PE film wrap is also used in many different industries such as shipbuilding, construction, agriculture, medical, …
Advantages and disadvantages of PE film wrapping
Advantages of PE film wrapping
- High strength: PE film has high mechanical strength, lightweight but ensures product protection properties, and has a high puncture and tear resistance when used correctly.
- High adhesion: PE film has good adhesion, helps to adhere to other layers of goods, and maintains a fixed adhesion when weather conditions change.
- Good waterproof ability: PE film is impervious to water and other liquids, helping to protect the product from the influence of the external environment.
- Various sizes: PE film has a variety of sizes, from 25cm to 50cm, suitable for many different products.
- Flexibility: PE film has high flexibility and elasticity, and is easy to bend and twist, helping to pack products of different shapes.
- Safe for health: PE film does not contain harmful substances, safe for human health and the environment.
- Reasonable price: PE film is cheap, and suitable for a variety of products and different applications in packaging and protection.
Disadvantages of PE film
Although PE (Polyethylene) film has many advantages, there are also some disadvantages as follows:
- Decreased elasticity: PE film can lose its elasticity after long use, resulting in the product inside being compressed or deformed.
- Does not meet the requirements of applications requiring flame retardant, oil, and chemical resistance.
- Not suitable for applications requiring high gloss film, such as high-grade product packaging.
Polyethylene - one of the most widespread and versatile polymers in the world. In this article, we will explore what polyethylene is, how it is obtained, and what advantages and disadvantages it has in the context of injection molding.

Definition and Production
Polyethylene is a polymer obtained from ethylene monomers through polymerization.
The production process of polyethylene includes the following stages:
- Polymerization: Ethylene monomers undergo polymerization, resulting in the formation of polyethylene molecules.
- Formation of the Polymer: Polyethylene can be made in various forms, including films, pipes, sheets, and other products.
Advantages of Polyethylene in Injection Molding
Injection molding is a technology for forming plastic products in which plastic material is melted and injected under pressure into molds. Polyethylene is a very suitable material for this process.
Here are some of its advantages:
- Plasticity: Polyethylene has high plasticity, making it suitable for molding into various shapes and configurations.
- Low Density: Polyethylene has low density, which makes products made from it lightweight and cost-effective in manufacturing.
- Corrosion Resistance: Polyethylene is resistant to most chemical substances, allowing its use in aggressive environments, including contact with water and chemicals.
- Electrical Insulation Properties: Polyethylene provides good electrical insulation, making it suitable for manufacturing insulation products.
Disadvantages and Limitations
Despite its many advantages, polyethylene also has some disadvantages:
- Thermal Stability: Polyethylene can melt at high temperatures, limiting its use in high-temperature applications.
- Mechanical Strength: Polyethylene may have lower mechanical strength compared to some other plastics, which may require additional reinforcement in constructions.
Applications in Injection Molding
Polyethylene is used in injection molding to produce various products, including plastic bottles, containers, automotive parts, household appliances, and other items where a combination of lightness, plasticity, and corrosion resistance is required.
