Conform with ASTM D5458 Standard Test Method for Peel Cling of Stretch Wrap Film.
General introduction
Peel cling fixture is fully engineered to comply with ASTM D5458 Standard Test Method for Peel Cling of Stretch Wrap Film, the global authoritative testing standard for self-adhesion (cling) performance of PE stretch wrap, pallet wrapping film, food cling film and hand stretch film.
The fixture adopts a fixed 20° inclined test platform as required by ASTM D5458:
Secure a large base film sheet flat on the inclined plane (no wrinkles/bubbles)
Attach a standard 1-inch (25.4 mm) wide film test strip onto the base film with uniform contact pressure
The fixture guides the universal testing machine (UTM) to peel the strip at constant speed, capturing peak peel force to calculate cling strength (N/25mm or lb/in)
Supports both unstretched & pre-stretched film testing (50%/100%/200% stretch ratios) to simulate real pallet wrapping scenarios.

Film cling directly determines pallet load stability, unwinding smoothness, and wrapping efficiency. This fixture delivers repeatable, lab-comparable cling data for film raw material R&D, production QC, incoming material inspection, and third-party certification labs. It eliminates inconsistent manual setups and meets US packaging industry export testing requirements.

One set fits all stretch film types: machine stretch wrap, hand stretch film, food PVC cling film, biodegradable PLA wrapping film
Complete supporting accessories included: precision 25.4mm film cutter, smoothing roller, conditioning template, cleaning wipes, calibration ruler
Step 1: Fixture Installation
Mount the fixture onto your UTM lower crosshead via the standard adapter, lock firmly, align the pulley pulling line vertically to the upper machine grip.
Step 2: Base Film Preparation
Cut base film to 5×20 inch size, lay flat on the 20° inclined plate, fix both ends with the bottom roller clamp, adjust to target pre-stretch ratio and lock the tension knob.
Step 3: Test Strip Lamination
Cut 25.4 mm wide film strip; smooth onto the center of base film with the supplied roller to remove air bubbles, attach strip tail to fixture upper clip.
Step 4: Test Execution
Set UTM speed to 305 mm/min, start tensile test. The machine records peak peel force automatically. Calculate cling strength = max peel force / 25.4 mm width.
Complete minimum 5 replicate samples per batch for average data as ASTM required.
Step 5: Post-Test Cleaning
Wipe the inclined plate with dry cloth to remove film residue, release all clamps, store in dry environment.
Plastic Stretch Film Manufacturers
Production online QC, formula modification R&D, adjust cling additive dosage to avoid over-sticky blocking or insufficient self-adhesion.
Packaging Material Inspection Labs & Third-Party Test Institutes
ASTM-standard testing for export certification, pallet wrapping material performance verification, official test report issuance.
Logistics & Pallet Wrapper End Users
Incoming raw film quality inspection, compare different film suppliers’ cling consistency, reduce loose pallet cargo risks during transit.
Food Packaging Industry
Food-grade PE/PVC cling film self-adhesion testing for supermarket packaging, fresh food wrapping.

Standard
ASTM D5458 defines a peel cling procedure to quantify the "cling" — the ability of a stretch wrap film to adhere to itself — between two layers of film, measured both in an unstretched and a stretched condition. Self-adhesion (cling) between two stretch wrap film layers under both stretched and unstretched states, using a constant-rate peel test on a universal testing machine (UTM) with dedicated inclined cling fixtures.
ISO 527-3 Plastics - TENSILE PROPERTIES - PART 3: FOR FILMS AND SHEETS
ISO 527-3 is a common international standard that is used to determine the tensile properties of plastic film or sheeting - a plastic test specimen with a thickness less than 1 mm. The tensile properties include tensile strength, yield strength, yield strain, strain at break, and in some cases Young's Modulus. Due to the flexible, delicate nature of these plastic specimens, both gripping and strain measurement can be a challenge.
ISO 527-3 Tensile Test of Plastic Thin Film Sheet
It covers the specimen preparation requirements of thin plastic sheets and films. Thin plastic specimens created with the practices of ISO 527-3 are tensile tested with the practices of ISO 527-1. Thin plastic specimens created in accordance with ISO 527-3 are cut, or punched from a sheet of thin plastic. ISO 527-3 specifies that thin plastic film of sheet specimens must be free from cracks or scratches that will affect the tensile test. ISO 527-3 allows for four specimen geometries that can be used for tensile testing. There are three acceptable dogbone shaped specimens that are acceptable. Specimen created following ISO 527-3 can be used to determine the tensile properties of thin plastic sheets and films including the tensile modulus of elasticity and the tensile energy to break (TEB).
ASTM D6195 provides procedures to quantify the loop tack property of pressure-sensitive adhesives (PSAs)—a critical metric for adhesives that form rapid, measurable bonds upon contact (e.g., tapes, labels, stickers). The standard focuses on two test methods (A and B) and is widely used for quality control and research in packaging, labeling, and adhesive manufacturing. It provides a quantitative measure of an adhesive's ability to form an immediate bond upon brief, light contact with a substrate, simulating real-world application conditions where minimal pressure and dwell time are typical.
ASTM D1894 quantifies surface slip resistance of plastic films and thin sheets sliding against identical film, metal, glass or other flat substrates, generating empirical friction data for production quality control and material performance evaluation. Test static (starting) and kinetic (continuous sliding) friction coefficients of plastic film & thin sheeting; primary for flexible packaging materials.
ASTM D5748 determine the resistance of stretch wrap / stretch film to penetration by a probe under a controlled, low-rate (quasi-static) single-velocity condition, while the film is clamped so it develops biaxial stress — the stress state most representative of real-world end use.
ASTM D1709: Standard Test Methods for Impact Resistance of Plastic Film by the Free-Falling Dart Method
ASTM D1709 test methods cover the determination of the energy that causes plastic film to fail under specified conditions of impact of a free-falling dart. This energy is expressed in terms of the weight (mass) of the missile falling from a specified height which would result in 50 % failure of specimens tested.
