The performance of PVC plastic wrapping tape in various temperature environments has a significant impact on its application range and use effects.
First, the stickiness of PVC tape will change significantly in low temperature environments. As the temperature decreases, glue tends to become more viscous, but at the same time its flexibility decreases. For example, when used outdoors in cold winter, the tape may become hard and brittle, which makes it difficult to fit complex-shaped surfaces when wrapping packaged items, and is prone to warping or breaking, thus affecting the sealing and sealing properties of the package. Solidity.
Secondly, the test of PVC plastic wrapping tape in high temperature environment should not be underestimated. When the temperature rises, the glue in the tape may soften, resulting in a decrease in viscosity. In some high-temperature warehousing or transportation scenarios, such as near heat sources or during hot summer transportation, the tape may not be firmly attached to the packaged items, causing the packages to fall apart and fail to protect and fix them.
Furthermore, temperature changes will also affect the tensile properties of PVC plastic wrapping tape. At low temperatures, the tensile strength of the tape will increase, but the brittleness will also increase, and it is easy to break suddenly during the stretching process; while at high temperatures, its tensile strength will decrease, and it may overextend or even lose its strength when subjected to a certain amount of tension. The elasticity after stretching affects the tightness and stability of the packaging.
From the perspective of color stability, the color of PVC tape may fade or change when exposed to high temperatures or direct sunlight for a long time. This not only affects the appearance of the tape, but also causes inaccuracy and confusion in information transmission in some cases where color is required to distinguish packaging contents or labeling.
In addition, due to cyclic changes in temperature, such as in areas with large temperature differences between day and night or during transportation that undergoes seasonal changes, PVC tape will repeatedly experience expansion and contraction. This thermal expansion and contraction effect may cause a gap between the tape and the packaged material, allowing air and moisture to enter, accelerating the oxidation or moisture deterioration of the packaged items, and also weakening the structural integrity of the tape itself and reducing its service life. .
The unwinding force of PVC tape will also change in different temperature environments. At low temperatures, the tape may become stiff and difficult to unwind, easily causing waste of tape and inconvenient use; at high temperatures, the unwinding force may be too small, causing the tape to loosen on its own when not in use, affecting normal packaging operations.
Understanding the performance changes of PVC plastic wrapping tape in different temperature environments is extremely important for rationally selecting usage scenarios, optimizing storage conditions, and developing and improving products to adapt to a wider temperature range.
