How does stretch film work to secure and protect items?
Author:admin Date:2023-07-06
Stretch film, also known as stretch wrap or pallet wrap, is a highly stretchable plastic film used to secure and protect items during storage, transportation, or shipping. It is commonly used in industries such as manufacturing, logistics, and warehousing. Stretch film works by utilizing its unique properties and application technique to tightly wrap around products or pallets, providing stability and protection. Here's how it works:
Elasticity: Stretch film is made from linear low-density polyethylene (LLDPE), a material that possesses excellent stretchability and elasticity. This means it can be elongated and stretched without breaking or losing its shape.
Film Thickness: Stretch film comes in various thicknesses, typically ranging from 15 to 30 microns (0.6 to 1.2 mils). Thicker films offer higher puncture resistance and load-bearing capacity.
Tensioning: To apply stretch film, it is unwound from a roll and manually or mechanically stretched. The tension applied during the wrapping process is crucial for achieving a secure and tight wrap. Stretching the film increases its elongation potential.
Cling Properties: Stretch film has cling properties on both sides. This means it adheres to itself when wrapped around an object, creating a tight and secure seal. The cling effect eliminates the need for additional adhesives or tapes.
Containment: As the stretched film is wrapped around the item or pallet, it contracts back to its original size, exerting a squeezing force. This force holds the load tightly together, minimizing movement and preventing shifting during handling, storage, or transportation.
Protection: Stretch film provides protection against dust, dirt, moisture, and other environmental factors that can potentially damage the goods. It acts as a barrier, shielding the items from external elements, thereby preserving their integrity.
Load Stability: By securely wrapping pallets or items together, stretch film enhances load stability. It helps prevent product tampering, reduces the risk of damage caused by impacts or vibrations, and improves overall safety.
Transparency: Stretch film is typically transparent, allowing for easy identification and visual inspection of the wrapped goods without the need for unwrapping. This feature is beneficial for inventory management and quality control purposes.
In summary, stretch film works by utilizing its stretchability, cling properties, and tensioning technique to tightly wrap and secure items or pallets. It provides stability, protection, and containment, ensuring that goods remain intact and undamaged during storage, shipping, or transportation.
