The raw materials of PETG media bottles generally meet the requirements of USP Class VI medical polymer materials. Medical polymer materials refer to polymer materials used to manufacture human internal organs, external organs, pharmaceutical dosage forms and medical devices, and their sources include natural biopolymer materials and synthetic biopolymer materials. There are 6 levels in USP Class I - USP Class VI in the US plastic classification test. The plastics rated as the sixth level of US medical plastics means that a very comprehensive and strict test has been established. Its test items include systemic toxicity test (mice), intradermal reaction test (rabbit), implantation test (rabbit). Grade VI is the gold standard for various medical-grade raw materials, and it is also a very high-quality choice for medical device manufacturers.
The above are the standards and requirements that PETG media bottles raw materials should follow. In addition to paying attention to this point, when purchasing bottles, enterprises should also pay attention to the overall control of product quality by suppliers, such as production process, quality inspection, etc., to ensure product quality.
