ASTM D882 is an ASTM International test method used to determine tensile properties of thin plastic sheeting and films. It is widely referenced for comparing material strength and elongation behavior in packaging films, liners, and other thin polymer products.
D882 applies to plastics under 1.0 mm (0.04 in.) thick and is commonly used for quality control, product development, and material comparison when test conditions and specimen preparation are tightly controlled.

ASTM D882-26 — Standard Test Method for Tensile Properties of Thin Plastic Sheeting
ASTM D882 is written for tensile testing of plastic films and thin sheeting below 1.0 mm thickness. It addresses key sources of variation that matter for thin materials, such as specimen thickness, specimen preparation, grip type, test speed, and how extension is measured.
This standard is often used both for routine production checks and for comparative material characterization where consistency and repeatability are important.
Quick Definition
Document type: Test method.
Primary purpose: Determine tensile properties of thin plastic films/sheeting (under 1.0 mm thick) using a tensile testing machine and appropriate gripping and extension measurement methods.
Common outputs: Tensile strength and elongation-related results (exact reported values depend on the edition and the options used).
What This Standard Covers
ASTM D882 covers tensile testing of plastics in the form of thin sheeting and films with thickness less than 1.0 mm (0.04 in.). It also recognizes that “film” is commonly used for thinner sheeting (with terminology defined separately in ASTM terminology standards).
The method allows different ways to measure specimen extension (for example, by grip separation or by dedicated extension measurement), and it includes a procedure to determine tensile modulus at a specified strain rate.
Why This Standard Matters in Testing
Thin films can be especially sensitive to grips, alignment, and extension measurement. ASTM D882 is often selected because it calls attention to these factors and supports more meaningful comparisons between lots, suppliers, and formulations when conditions are controlled.
It is also frequently used as a reference method when film products are purchased or released against internal specifications that cite D882 results.
Common Materials, Product Types, or Applications Covered
ASTM D882 is commonly applied to thin polymer films and sheet products, including:
- Packaging films (converted film, barrier layers, and multilayer structures where a film tensile check is required)
- Industrial liners and protective films
- Thin plastic sheets used in fabrication, lamination, or thermoforming feedstock (when under the thickness limit)
- General-purpose QC testing of thin plastic webs
When thickness is 1.0 mm (0.04 in.) or greater, tensile testing is typically handled by other plastics tensile methods (such as ASTM D638), so edition matching is important when a product spec cites both thickness and method.
Common Test or Verification Workflow
In many labs, ASTM D882 is run as a repeatable incoming or in-process check with controlled specimen prep and a standardized conditioning and test routine.
Common workflow elements: Prepare film specimens to the required geometry, verify thickness, mount in suitable film grips, apply tensile loading at the specified rate, measure extension using the chosen approach, and report tensile properties in the required units (SI is the reference unit system in the current ASTM edition record).
Equipment Commonly Used for This Standard
ASTM D882 points most directly to a tensile testing system configured for thin, low-force specimens and stable gripping.
Common equipment categories: Universal testing machine (electromechanical UTM is common for films), appropriate low-capacity load cell(s), film grips selected to minimize slippage and tearing at the jaws, and an extension measurement approach matched to the accuracy requirement (crosshead/grip separation or dedicated extensometry where applicable).
Practical selection cautions: Thin film results can shift with grip design, alignment, and how extension is measured. If you are comparing pneumatic vs. mechanical grips, or deciding whether an extensometer/optical extension solution is needed for your reporting requirements, you can request pricing for a configured tensile system based on your film type and force range.
How to Read This Designation or Revision
Base designation: ASTM D882 identifies the test method for tensile properties of thin plastic sheeting.
Year suffix: A designation such as ASTM D882-26 refers to the edition associated with the year “26” (2026). Test parameters and reporting expectations can change between editions, so purchasing, compliance, or customer documentation should cite the full designation including the year.
Revision sensitivity: If a customer specification calls out D882 with a specific year (or references legacy results), use the exact cited edition when setting up test conditions and reporting formats.
Related Standards, Methods, or Frameworks
ASTM D882 itself points users to additional references depending on thickness and terminology needs.
Commonly paired references: ASTM D638 for thicker plastics tensile testing (at or above 1.0 mm), ASTM D883 for plastics terminology (including film vs. sheeting terminology), and ASTM D4000 as a directory reference for existing ASTM plastics materials standards. The ASTM listing also notes technical similarity to ISO 527-3 for film/sheet tensile testing.
