Recommended Apparatus for ASTM D5458 Testing
Accurate testing under ASTM D5458 requires specialized fixtures and instrumentation capable of measuring the large elongations and relatively low forces associated with stretch wrap films. A properly configured universal testing system ensures that film specimens stretch uniformly and fail within the gauge section rather than at the grip interface.
Typical ASTM D5458 test systems include the following components.
Stretch Film Preparation Fixture
A dedicated ASTM D5458 stretch film fixture is used to pre-stretch the specimen to a controlled elongation prior to tensile measurement. The apparatus consists of an inclined platform with a clamping carriage and anchor point that allows the film to be stretched smoothly along a defined path. This fixture ensures repeatable specimen preparation and helps simulate the elongation behavior of pallet wrap films during real packaging operations.
Film Grips
After preparation, the specimen is transferred to the universal testing machine using grips designed specifically for thin polymer films. Because stretch wrap materials are extremely thin and capable of very high elongation, grip selection is critical.
Common grip configurations include:
• Self-tightening roller grips for high-elongation film materials
• Pneumatic film grips that apply controlled clamping pressure
• Rubber-faced jaws that increase friction while preventing specimen damage
These gripping systems distribute clamping force evenly across the film width and prevent tearing or slippage during large extension tests.
Load Cells
Stretch wrap film testing typically requires low-capacity load cells due to the relatively small tensile forces generated by thin films. High-resolution load cells allow the testing machine to accurately capture the small variations in tension that occur during film stretching and relaxation.
Universal Testing Machine
A universal testing machine used for ASTM D5458 should provide:
• precise crosshead speed control
• sufficient crosshead travel to accommodate large elongations
• high-resolution displacement measurement
• software capable of generating force-elongation curves
Extended travel capability is particularly important because stretch films frequently reach elongations of 200–300% or greater before failure.
Universal Test Machine Co. provides ASTM D5458 stretch film preparation fixtures, thin-film grips, and compatible universal testing systems designed to perform stretch wrap film testing according to industry standards. These solutions integrate with universal testing machines from major manufacturers and allow laboratories to perform repeatable stretch wrap film characterization for packaging and logistics applications.
