Factors to Consider When Selecting PE Stretch Film

When choosing PE (polyethylene) stretch film, multiple specific factors should be considered to ensure that the selected film meets specific application requirements and can perform at its best during use.

1.Thickness

Membrane thickness: The common thickness range is from 15 μ m to 50 μ m or thicker. When choosing, the weight and type of packaging contents should be considered:

（1）Lightweight items: 15 μ m to 20 μ m;

（2）Medium sized items: 20 μ m to 30 μ m;

（3）Heavy or irregular items: 30 μ m and above.

2.Stretching and strength

（1）Tensile strength: Choosing a film with high tensile strength can improve its load-bearing capacity and ensure that it will not break during packaging and transportation

（2）Ductility: A good PE stretch film should be able to maintain its extensibility during the stretching process and not easily tear.

3.Transparency

（1）Transparency requirement: If you need to view the contents of the package, choose a high transparency stretch film; If visibility is not required, black or white film can be chosen to provide additional privacy and light protection capabilities.

4.Protective properties

（1）Moisture resistance: For goods that are prone to moisture, choose a film with good moisture resistance and waterproofness to prevent moisture from seeping in and protect the contents.

（2）UV resistance performance: If the film is used for outdoor storage or transportation, it is recommended to choose UV resistant PE stretch film to prevent the film from aging due to sunlight exposure.

5.Application Environment

（1）Temperature and humidity: Consider the temperature and humidity of the packaging environment, and choose a film that can maintain performance under specific climatic conditions. For example, certain membranes can maintain toughness in low-temperature environments.

（2）Chemical resistance: If there may be chemicals present in the storage environment, consider choosing a PE film that resists specific corrosive substances.

6.Environmental Friendliness

Recyclability: Prioritize the use of films made from recyclable or environmentally friendly materials, which can help reduce environmental impact and meet sustainable development needs.

In short. When choosing PE stretch film, considering the above factors comprehensively can help you find the most suitable product, thereby ensuring the safety and integrity of the items during packaging and transportation. Understanding specific needs and evaluating the pros and cons of different choices can help you make the best decisions.
