Does stretch film break or become damaged easily when wrapping sharp or irregularly shaped items?

During the packaging process, stretch film needs to face various shapes of objects, among which sharp or irregular shaped objects put forward higher requirements for the durability and protective performance of stretch film. When using stretch film for packaging, if the material selection, thickness, and process are improperly handled, the film layer may be broken or damaged, affecting the overall stability and protective effect of the packaging.
The material and formula of stretch film have a direct impact on its anti-rupture ability. Different types of stretch films have differences in flexibility and tensile strength. Generally, the use of materials with stronger toughness can improve its adaptability to sharp objects. For example, materials with higher elasticity can effectively disperse pressure when impacted by external forces, reducing the damage of the film layer caused by excessive local force.
The thickness of stretch film is also an important factor in determining its durability. Although thinner film layers can meet the needs in general packaging applications, they may be easily punctured or torn due to stress concentration when facing objects with complex shapes and protruding edges. Therefore, when packaging objects with sharp corners, choosing thicker and tougher film materials can effectively reduce the risk of rupture. In addition, the multi-layer structure design of the reinforced film layer can also improve its overall puncture resistance, making it less likely to break after being stressed.
The production process of the stretch film also affects its durability. Different processes will affect the uniformity and tensile strength of the film layer. During the production process, by optimizing the stretch ratio and cooling process, the toughness of the film layer can be improved so that it can better adapt to irregularly shaped items during the stretching process without breaking easily. In addition, the use of special additives, such as tear enhancers or highly elastic materials, can further improve the durability of the stretch film, making it more reliable when packaging sharp or angular items.
The method of use also plays a key role in the protective ability of the stretch film. In the actual packaging process, if the winding method of the stretch film is unreasonable, it may cause uneven force and increase the possibility of rupture. For example, when packaging angular items, the cross-winding method can effectively disperse the force and make the tension distribution of the film layer more uniform. In addition, appropriately increasing the overlap of the film layer during wrapping can enhance the overall puncture resistance and reduce the damage caused by excessive force on individual parts.
