In modern logistics and transportation, stretch film plays an extremely important role, and its anti-vibration and buffering performance is directly related to the safety and integrity of goods.
Stretch film mainly absorbs and disperses the vibration and impact force generated during transportation through its own elastic deformation. When the goods are bumped and collided, stretch film can buffer the external force to a certain extent and reduce the risk of damage to the goods. However, there are still some limitations in the anti-vibration and buffering performance of stretch film. For example, the buffering capacity of ordinary stretch film is relatively limited, and the protection of some fragile and delicate items may not be sufficient.
From the perspective of materials, the elastic modulus and damping coefficient of traditional stretch film materials are insufficient in dealing with complex transportation environments. It is possible to consider using new composite materials, such as adding rubber particles or other elastomer components, to improve the elasticity and damping characteristics of stretch film and enhance its buffering effect.
In terms of structural design, changing the texture or thickness distribution of stretch film can optimize its anti-vibration and buffering performance. For example, a stretch film designed with a wavy or honeycomb structure can provide more deformation space when subjected to external force, thereby better dispersing energy.
The production process also has a significant impact on the vibration-proof and buffering properties of stretch film. Accurately controlling the stretching process parameters, such as stretching ratio and stretching speed, can make the molecular orientation of stretch film more reasonable and improve its mechanical properties and buffering capacity.
In addition, the multi-layer composite structure of stretch film is a very promising direction for improvement. By combining different functional layers, such as combining an outer layer with high strength with an inner layer with good buffering performance, the packaging stability and vibration-proof and buffering properties of stretch film can be taken into account.
In practical applications, the specifications and winding methods of stretch film can also be reasonably selected according to the characteristics of the goods and transportation conditions. For example, for fragile goods, the number of winding layers of stretch film can be increased or a special winding pattern can be adopted to maximize its vibration-proof and buffering effect. Through the analysis and improvement of stretch film in terms of materials, structure, process, etc., its vibration-proof and buffering properties in logistics transportation can be significantly improved, and the safety of goods during transportation can be better guaranteed.
