Bottle tests

Bottle testing verifies the mechanical strength, performance, and dimensional accuracy of rigid packaging for liquids. These tests apply to glass , plastic (PET, HDPE, PP), metal , and composite .
They are essential for checking strength, leak-proofness, resistance to internal pressure and drops, as well as compliance with packaging and transport standards .

Methods and parameters measured

Bottle testing covers several types of physical and mechanical tests adapted to the constraints of use:

• Drop tests : measurement of impact resistance to assess resistance to breakage or deformation after impact.
• Compression or crushing tests : determination of the maximum force that can be withstood before breakage, useful for storage and palletizing.
• Internal pressure tests : verification of resistance to pressure exerted by the liquid, particularly important for carbonated beverages.
• Leak testing : detection of leaks or closure defects on cap/bottle systems.
• Dimensional control : measurement of circularity, height, wall thickness and neck.
• Accelerated aging tests to assess the stability of the material over time or under environmental stresses.

These tests are carried out according to ISO, ASTM, EN standards or according to manufacturers' specifications , guaranteeing compliance with the requirements of the packaging sector.

For further analysis, also check out the compression test , the tensile test or the leak test .

Industrial applications

Bottle testing is used at every stage of development, manufacturing, and quality control:

• Food and beverage packaging : control of glass or PET bottles intended for water, juices, sodas, wines or oils.
• Cosmetics and pharmaceuticals : verification of the resistance and compatibility of plastic or aluminum bottles with the packaged products.
• Chemical and detergent industry : testing of resistance to solvents and acids, measurement of chemical and mechanical compatibility.
• Materials and polymers : validation of the properties of resins, additives and formulations used in the manufacture of packaging.

These analyses guarantee packaging safety , regulatory compliance and customer satisfaction , while reducing the risks of non-compliance in production.

Analytical interest and complementarity

Bottle testing can be combined with other tests for a comprehensive evaluation of the material and the performance of the finished product:

• Bending test to evaluate the rigidity of the walls;
• DSC thermal analysis to study the crystallinity of the polymer;
• TGA analysis to measure thermal stability;
• FTIR infrared spectroscopy to identify the composition of materials;
• Total immersion tests to evaluate the resistance of packaging to prolonged contact with liquids.

These complementary approaches ensure a complete characterization of the physical and chemical performance of the packaging.
