Can plastic bottle testing** be done? What are the testing items and standards for plastic bottles? How much does the impact testing of plastic bottles cost? How long does it take for a plastic bottle inspection report to be issued? Foshan Huajin's third-party material testing laboratory can provide all kinds of plastic bottle testing services, including quality testing, composition testing, impact resistance, hazardous substances, food grade identification, pressure resistance, RoHS testing, etc. As a third-party testing center, the institution has CMA, CNAS certification and testing qualifications, complete testing equipment, scientific and reliable data, and can issue a nationally recognized plastic bottle test report within 5-10 working days.
Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Polyester (PET), polyethylene (PE), and polypropylene (PP) are widely used as raw materials for plastic bottles, and the corresponding organic solvents are added, heated at high temperatures, and then blown by plastic molds, extruded, or injection molded plastic containers.
As one of the common packaging containers in modern life, plastic bottles are widely used in various industries. However, plastic bottles can have some potential quality and safety issues, so testing them is important. This article will introduce the relevant content and implementation standards of plastic bottle testing.
The testing content of plastic bottles mainly includes the following aspects.
1.Appearance inspection: Appearance inspection is mainly to check the appearance of plastic bottles, including the flatness, finish, color uniformity of the bottle body, etc. The surface quality of the plastic bottle can be judged through the appearance inspection to ensure that its appearance meets the standard requirements.
2.Size and capacity testing: Size and capacity testing is to measure and verify the size and capacity of plastic bottles, including bottle body height, bottle mouth diameter, bottle bottom diameter, bottle thickness, etc. Dimensional and capacity testing ensures that the geometric dimensions and capacity of the plastic bottles meet the requirements of the standard.
3.Physical property testing: Physical property testing is mainly to test the physical properties of plastic bottles, including the strength, pressure resistance, impact resistance, heat resistance, etc. of the bottle body. Through physical property testing, the performance of plastic bottles in actual use can be evaluated to ensure that they have sufficient strength and durability.
4.Chemical performance testing: Chemical performance testing is to test the chemical properties of plastic bottles, including whether the inner wall of plastic bottles contains harmful substances, whether they meet the relevant standards of food contact materials, etc. Through chemical performance testing, it can ensure that plastic bottles will not produce harmful substances in specific environments such as contact with food, and ensure the health and safety of users.
There are many plastic bottle testing items, and the following are the regular items:
Leak testing. Check that the plastic bottle is able to seal the cap tightly.
Microbial testing. Detect plastic bottles for harmful microorganisms.
Light transmittance detection. Check whether the light transmittance of the plastic bottle meets the standard.
Factory inspection. Conduct quality inspection of plastic bottles before leaving the factory.
Water pressure resistance test. Test the strength of plastic bottles under pressure.
Leak detection. Inspect whether the plastic bottle is able to remain sealed under pressure.
In addition, there are chemical composition, melt index, air tightness detection, low temperature freezing detection, halogen testing, torque testing, anti-static testing, rigidity testing, ring stiffness testing, sealing firmness testing, dissolved oxygen testing, bubble testing, defect testing, RoHS testing, food grade identification, migration element analysis, etc.
The testing and implementation standards of plastic bottles are also an important basis for the testing of plastic bottles.
The testing standards for plastic bottles are as follows:
1. Appearance quality inspection standards: the bottle mouth should be smooth and flat, and the size and thickness should meet the standard requirements; The thickness of the bottle should be uniform, and there should be no obvious deviation or different thickness; The cap should be free of cracks, holes or deformations, and the cap should fit snugly and remain tightly sealed.
2. Size and capacity standards: The size and capacity of plastic bottles should meet the relevant standards to ensure that they can hold predetermined items or liquids, and are convenient to use and store.
3. Material standards: The materials used in plastic bottles should meet relevant standards and should not contain harmful substances to ensure the safety and environmental protection of plastic bottles.
4. Performance standards: Plastic bottles should have certain mechanical, thermal, and chemical properties to ensure that they can withstand the influence of various environments and conditions during use.
In addition, depending on the use scenario and use, the testing standards for plastic bottles may also include requirements in other aspects, such as hygienic standards for food-grade plastic bottles, sterility standards for medical-grade plastic bottles, etc.
Plastic bottle testing and inspection process:
1. Fill in the application form: contact Huajin testing staff to confirm the testing standards and projects, and sign the power of attorney.
2. Arrange to send samples: send the samples by express or directly to our laboratory.
3. Product testing: After payment, the laboratory arranges testing and issues a draft report.
4. Confirm the draft report and issue a formal report.
5. Report bill delivery service, as well as report interpretation and after-sales service.
The above is the relevant introduction of Huajin Testing on plastic bottle testing services, more about plastic bottle testing costs, standards, projects, cycles and other issues can be consulted by consulting ** engineer or call us. (Test The testing cycle, method and steps are subject to the engineer, if the sample is special, you can communicate with the engineer about the particularity of the sample, and the institution can design a reasonable testing and analysis plan for you to save your time).
