What should be checked regularly during the storage of plastic stretch film

Plastic Stretch Film is a key material widely used in packaging, fixing and protecting various items. Regular inspection during its storage process is important to ensure the quality of the film, extend its service life and avoid potential risks. significance.

First of all, appearance inspection is the basic link in storing plastic stretch film. This process mainly focuses on whether there are scratches, cracks, stains, mildew and other abnormal phenomena on the surface of the film. These defects not only affect the appearance of the film but may also have a negative impact on its tensile properties, self-adhesion and overall service life. Therefore, before each storage or after a certain period of time, a comprehensive visual inspection of the film must be carried out to ensure that its surface remains clean, flat and free of damage.

Transparency is one of the important indicators for evaluating the quality of plastic stretch film. Highly transparent films can effectively display the appearance of packaged items while reducing potential damage to items from light. During storage, the transparency of the film needs to be checked regularly to ensure that it has not been reduced by aging, contamination or improper storage. If the transparency is found to have dropped significantly, the film should be replaced in time to avoid affecting the packaging effect.

Stretch performance is the core characteristic of plastic stretch film, which is directly related to whether the film can closely fit the packaged items during the packaging process, thereby providing sufficient fixation and protection. During storage, the tensile properties of the film must be checked regularly, including key indicators such as tensile strength and elongation at break. These performance tests can be carried out through professional tensile testing machines to ensure that the tensile properties of the film meet actual use requirements.

Self-adhesion is another key performance of plastic stretch film, which determines whether the film can be firmly attached to the packaged items during the packaging process, thereby preventing the items from being displaced or damaged during transportation. During storage, the self-adhesiveness of the film should be checked regularly to ensure that it has not been reduced by prolonged storage, temperature fluctuations or contamination. If the self-adhesiveness drops significantly, the film should be replaced immediately to ensure that the packaging effect is not affected.

Inspection of the storage environment cannot be ignored either. In addition to a detailed inspection of the film itself, conditions such as temperature, humidity and light in the storage environment should be regularly assessed. These environmental factors have an important impact on the storage quality of the film. For example, excessively high temperature may cause the film to soften and deform, and even affect its tensile properties and self-adhesiveness; while excessive humidity may cause the film to become damp and moldy, thus reducing its service life. Therefore, during the storage process, the temperature and humidity of the storage environment should be regularly monitored to ensure that they are maintained within an appropriate range to maintain the quality and performance of the plastic stretch film.
