Transparent Heat Shrink Wrap Maintenance:

1. Storage environment control

Transparent heat shrink wrap should be stored in a dry, cool, and light-proof environment to avoid degradation of material performance. According to the material characteristics, the recommended storage temperature is 15-30℃ and the relative humidity is 40%-60%. In such an environment, the film can maintain its physical properties and transparency and extend its shelf life. If the storage environment is too humid or the temperature is too high, the film may become soft, sticky, or its performance may deteriorate. A humid environment will cause the film to absorb moisture, affecting its moisture-proof performance and shrinkage effect, while high temperature may cause the film to shrink or deform prematurely, making it unable to function normally in actual use. Therefore, choosing a suitable storage environment is crucial to ensuring the quality of transparent heat shrink film. The warehouse should be equipped with good ventilation equipment and temperature and humidity control devices, and the storage conditions should be checked regularly to ensure that the film is always in the best storage state to meet the needs of packaging production and use.

2. Avoid contact with sharp objects

During handling and storage, transparent heat shrink film should be avoided from contact with sharp objects to avoid scratches or cracks. According to actual tests, contact with sharp objects may cause scratches on the surface of the film, affecting its transparency and shrinkage performance. During packaging and transportation, the integrity of the film is directly related to the protective effect of the product. Once the film is scratched or broken, its sealing and protective properties will be greatly reduced, causing the product to be exposed to the external environment, increasing the risk of contamination and damage. Therefore, smooth tools should be used during handling, and equipment with sharp edges should be avoided. At the same time, when storing, the film should be placed on a flat and smooth shelf, away from areas where sharp objects may be generated, such as metal fragments, wood thorns, etc. For damaged films, they should be replaced or repaired in time to ensure the quality of packaging and avoid unnecessary losses to the product due to problems with packaging materials.

3. Correct heating method

When using transparent heat shrink film, the correct heating method should be used to ensure that the film shrinks evenly and forms a tight package. According to actual tests, when using a hot air gun or shrinking furnace, the temperature should be controlled between 100-150℃, and the heating time should be adjusted according to the thickness of the film and the size of the product. The correct heating method is one of the key factors to ensure the packaging effect. If the heating temperature is too high, the film may age, turn yellow or even crack prematurely, affecting the appearance and protective performance of the packaging; if the heating time is insufficient, the shrinkage may be incomplete, the film cannot fit tightly to the surface of the product, the packaging may be loose, and it cannot effectively resist the interference of external factors. Therefore, when using a hot air gun, the temperature and heating time should be reasonably set according to the characteristics of the film and the requirements of the product to ensure that the film is evenly heated. At the same time, operators should undergo professional training and master the correct heating techniques to avoid local overheating or uneven heating, and improve packaging quality and production efficiency.

4. Regularly check the quality of the film

During use, the quality of the transparent heat shrink film should be regularly checked to ensure that it has not aged, discolored or degraded. According to industry recommendations, each batch of film should be sampled and tested before use to check its tensile strength, transparency and shrinkage performance. If the quality of the film is found to have deteriorated, it should be replaced in time to avoid rupture or incomplete shrinkage during the packaging process. Regularly checking the quality of the film is an important means to ensure the stable operation of the packaging production line and qualified product quality. During the production process, if unqualified films are used, packaging failure may occur, production costs and time may be increased, and even product delivery and sales may be affected. Through regular sampling tests, it is possible to promptly detect whether the film has problems such as aging, discoloration, and reduced tensile strength, and take corresponding measures, such as adjusting storage conditions and replacing film batches. This not only helps to improve the qualified rate of packaging, but also avoids product damage and customer complaints caused by packaging quality problems, and maintains the good image and economic benefits of the company.

5. Avoid long-term exposure to high temperature environments

Transparent heat shrinkable films should avoid long-term exposure to high temperature environments to avoid affecting their performance. According to actual tests, long-term exposure to high temperature environments may cause the film to shrink prematurely or its performance to deteriorate. During storage and transportation, if the film is in a high temperature environment for a long time, such as an open-air warehouse in summer or an area close to a heat source, the physical properties of the film may change, such as becoming brittle and reducing shrinkage, making it unable to meet normal packaging requirements. In addition, premature shrinkage may also cause the film to deform before use, affecting the smooth progress of packaging operations. Therefore, when storing, try to avoid placing the film in a high temperature environment, such as near heating equipment, direct sunlight, etc. If it is necessary to store it in a high temperature environment for a short time, appropriate protective measures such as sunshade and heat insulation should be taken to reduce the impact of high temperature on the performance of the film, ensure that the film can perform its packaging function normally when in use, and ensure the quality and packaging effect of the product.

6. Reasonable stacking and handling

During storage and handling, transparent heat shrink film should be reasonably stacked and handled to avoid excessive extrusion or bending. According to actual tests, excessive extrusion or bending may cause deformation or rupture of the film, affecting its use effect. Transparent heat shrink film is usually stored and transported in the form of rolls. If it is stacked too high or subjected to excessive pressure, it may cause sliding or deformation between the layers inside the film roll, resulting in the film not being able to shrink evenly during use, affecting the tightness and appearance quality of the packaging. At the same time, excessive bending of the film may cause local stress concentration, cracking or damage to the film, reducing its tensile strength and puncture resistance, and increasing the risk of rupture during packaging. Therefore, the film roll should be placed vertically during storage, and the stacking height should be controlled to avoid exceeding the bearing capacity of the film roll. During handling, it should be handled with care, and appropriate handling equipment and tools should be used to prevent the film from being collided and squeezed. Deformed or damaged film rolls should be processed or adjusted in time to ensure that they are in good condition before use to meet the quality and efficiency requirements of packaging production.
