How to choose high-quality stretch film?

Choosing high-quality stretch film is crucial for ensuring the safety of goods during transportation and storage. Here are some key factors to consider when choosing high-quality stretch film:

Material quality: High quality stretch film is usually made of linear low-density polyethylene (LLDPE), which has good tensile properties, tear resistance, and puncture resistance. Check whether the product uses high-purity raw materials to ensure its durability and reliability.

Stretching rate: The stretching rate of a stretch film refers to the degree to which it can be stretched. A higher stretch rate means that more goods can be wrapped with less film, thereby saving costs. However, attention should also be paid to the retention and recovery of the membrane under high tensile conditions.

Transparency: The high transparency stretch film makes it easier for you to view the items inside the package, which is crucial for inventory management and safety checks.

Adhesive and sealing properties: High quality stretch film should have appropriate self-adhesive properties to securely wrap around goods without the use of additional tape. Meanwhile, it should also be able to maintain good adhesion performance under various temperature conditions.

Thickness: Choose the appropriate thickness according to the type of goods that need to be packaged. Thicker films are more suitable for heavy or sharp edged items, while thinner films are suitable for light or smooth surface items. Generally speaking, the thickness ranges from 8 microns to 30 microns.

Environmental adaptability: Consider the performance of stretch film under different environmental conditions, such as temperature changes, humidity, etc. Some high-end products can maintain excellent performance even under extreme weather conditions.

Brand reputation and service: Choosing stretch films from well-known brands can ensure product quality, and these brands often provide better after-sales service and technical support.

Environmental considerations: If possible, choose products that are recyclable or made from recycled materials, which can help reduce the impact on the environment.

By considering the above factors comprehensively, you can better choose high-quality stretch film that suits your needs. In addition, obtaining samples for actual testing is also a good method for evaluating the performance of stretch films.
