How does the thickness of film shrink customization affect its strength?

Publish Time: 2024-04-30
The thickness of film shrink customization has a direct and significant impact on its strength. First of all, we need to make it clear that the thickness of shrink film customization refers to the amount of material accumulation per unit area, usually measured in microns (μm) or millimeters (mm). Strength refers to the material's ability to resist damage from external forces and is one of the important indicators for evaluating material performance.
When the thickness of shrink film customization increases, its internal fiber and molecular structure will become closer. This tight packing allows the material to better disperse and resist the impact of external forces when it is acted upon. Therefore, thicker shrink film customizations tend to have higher strength and can better protect packaged items from damage during transportation or storage.
Specifically, thicker shrink film customization can withstand greater tensile force and impact force. During the packaging process, shrink film customization requires wrapping items tightly through heat shrinkage. Thicker films can better maintain their shape and dimensional stability, thereby ensuring the tightness and integrity of the packaging. In addition, when items are subject to external impact, thicker shrink film customization can provide better cushioning and protection, reducing damage to items.
However, the thickness of shrink film customization is not as thick as possible. Excessively thick shrink film customization will not only increase the cost, but may also affect the aesthetics and practicality of the packaging. At the same time, a film that is too thick may be more difficult to control its shape and dimensional stability when heated and shrunk, resulting in poor packaging results.
Therefore, when selecting shrink film customization, the appropriate thickness needs to be determined based on specific packaging needs and item characteristics. Generally speaking, for items that are heavier, have irregular shapes, or require a higher level of protection, thicker shrink film customization can be selected to ensure the integrity and safety of the packaging. For some items that are light, fragile or need to be displayed, you can choose thinner shrink film customization to balance cost and effect.
In short, the thickness of shrink film customization is one of the important factors affecting its strength. When selecting shrink film customization, the appropriate thickness needs to be determined based on specific packaging needs and item characteristics to ensure the integrity and safety of the packaging.
