Ointment tubes are typically made from either plastic or aluminum. Due to their cost-effectiveness and durability, they are commonly used for packaging and dispensing topical medications, such as ointments, creams, and gels for treating various conditions.
To ensure the packaged product’s quality and safety, ointment tubes undergo a variety of tests
Material testing includes physical properties and barrier properties tests. Tensile strength tests are to find out how strong and how flexible the packaging materials are. Pull the material to see when it breaks, while flexibility tests bend it to check for cracking. This matters for how the tube handles squeezing and everyday use.
Labthink C610M Auto Tensile Tester is professionally applicable to measurement of tensile, peeling, deformation, tearing, heat sealing, adhesive, puncture force, opening force, pulling force and low speed unwrapping force as well as other properties of plastic films, composite materials, soft package materials, plastic flexible tube, adhesives, adhesive tapes, label stickers, medical plasters, release paper, protective films, combined caps, aluminum foils, diaphragms, back sheets, non-woven fabrics, rubber and paper, etc.
Barrier Properties tests measure how well does the tube prevent air or moisture from getting in, especially for sensitive products.
Labthink C403H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249，ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others.
Leakage testing is to ensure that the tube does not leak its contents. Pressure Testing is often performed to mimics the stresses of squeezing or being stored. Water bath testing and visual inspection are also common ways of detecting leakage.
Labthink C660B Leak and Seal Strength Tester is professionally designed for the leakage tests of packages for food, drugs, medical instruments, household chemical products, cars, electronic components, stationeries and other industrial products. The instrument also can be used to test seal performance of specimens after falling and compression tests
By combining these tests, manufacturers can ensure that ointment tubes are safe, effective, and keep their contents in perfect condition.
