Information on the most widely used ASTM standards within the materials testing industry
Packaging
Mechanical testing in the packaging industry determines the packaging's resistance to compression, impact, and tension, directly ensuring the safety of contents during storage and transportation. UnitedTest can cover comprehensive mechanical testing for packaging, complying with ISO, ASTM Standards, and provides customized testing solutions for compression, drop, tear, and more.
Packaging quality inspection is a core part of quality control across multiple key industries, including food, pharmaceuticals, cosmetics, electronics, and industrial products. Its importance lies not only in ensuring the integrity of products during storage, transportation, and sales until they reach consumers, but also directly relates to product safety, brand reputation, resource efficiency, and regulatory compliance.
Packaging quality inspection covers multiple parameters, with main items including: 1. Physical and mechanical properties: such as compressive strength, stacking performance, bursting strength, edge crush strength, peel strength, sealing performance (seal strength and integrity), and drop impact performance; 2. Barrier performance: testing the permeability rates against gases (such as oxygen and carbon dioxide) and water vapor; 3. Seal integrity: used to detect minute leaks through methods such as vacuum decay, high voltage leak detection, or dye penetration; 4. Material hygiene and safety: testing for migration of specific substances, residual solvents, heavy metals, and fluorescent substances; 5. Appearance and print quality: including dimensional accuracy, color consistency, barcode readability, print adhesion, and surface defects. The inspection scope covers the entire lifecycle from packaging raw materials (paper, plastic film, metal foil, adhesives, etc.), semi-finished products (such as cartons and containers), to final packaged products, and can be conducted under simulated conditions of different temperatures, humidity, and transport vibrations.
The core equipment includes: Electronic universal testing machine for accurately measuring tensile, compressive, tear, and other mechanical properties; Intelligent electronic compression tester, specifically for crush and stacking tests of corrugated cartons; Permeability tester and water vapor transmission rate tester, which quantify the oxygen and moisture barrier properties of packaging materials; Seal tester, which assesses the overall sealing performance of packaging using vacuum or positive pressure methods; Leak detector, which uses high-sensitivity sensors to locate microscopic leaks; Friction coefficient tester, which evaluates film openability and conveyor performance; Drop tester, which simulates vertical impacts to evaluate packaging protection; and laboratory environmental chambers, which provide standardized temperature and humidity testing conditions.
