Stretch Pallet Wrap Testing: From Puncture to Impact Resistance

Understanding the Role of Stretch Pallet Wrap in Packaging

Stretch pallet wrap plays a vital role in industrial packaging, particularly in logistics and warehousing. Designed to secure and stabilize palletized goods, this thin plastic film must maintain high performance across various conditions. To ensure quality and reliability, manufacturers and quality control professionals must conduct a series of mechanical and physical tests. These assessments not only validate product quality but also ensure compliance with customer and regulatory expectations.

A Cell Instruments Co., Ltd., we offer advanced solutions for evaluating the performance of stretch pallet wrap, enabling precise control over material properties and helping customers optimize their packaging systems.

Puncture Test: Measuring Film Toughness Under Stress

IL prova di foratura is essential to determine the film’s resistance to sharp objects or concentrated stress points. During this test, a probe penetrates the stretch film at a controlled speed, and the force required to puncture it is recorded. This test is critical for applications where stretch wrap is exposed to irregular or pointed loads during transit.

Peel Cling Test: Evaluating Film-to-Film Adhesion

Peel cling test measure the cling force between overlapping layers of stretch wrap. High cling values are essential for load stability, but excessive cling can lead to film blocking during unwinding. This test helps balance wrap effectiveness with operational efficiency in automatic or manual applications.

Tensile Strength Test: Determining Load-Holding Capability

IL tensile strength test measures how much force the film can withstand before breaking when stretched. High tensile strength indicates better load retention and resistance to tearing under tension. It is an indispensable performance metric for high-load and high-speed packaging operations.

Elongation Test: Assessing Flexibility and Stretch Performance

Elongation testing determines how far the stretch wrap can extend before breaking. This property is crucial for gauging the film’s elasticity, which directly affects the wrap’s ability to conform to irregular loads and maintain tension during transport.

Elmendorf Tear Test: Measuring Resistance to Propagation of Tears

IL Elmendorf tear test evaluates the wrap’s ability to resist the growth of a tear once it begins. A tear in transit can compromise the load’s safety. This standardized method helps ensure reliability, especially in films used in rough handling environments.

Impact Resistance Test: Ensuring Durability Against Sudden Force

In an impact resistance test, the film is subjected to a falling dart or a sudden force to simulate drop or impact scenarios. This helps verify whether the stretch pallet wrap can protect goods from shock damage during loading and unloading processes.

Thickness Test: Ensuring Uniform Material Distribution

IL thickness test provides insight into the uniformity of film production. Inconsistent thickness can lead to weak spots, resulting in breakage or compromised load security. Consistent thickness helps maintain overall performance across the entire stretch film roll.
