ETO-sterilizable R-PET films refer to a specific type of plastic film that is made from recycled polyethylene terephthalate (R-PET) and can be sterilized using ethylene oxide (ETO) gas. Polyethylene terephthalate (PET) is a common thermoplastic polymer resin used in various applications, including packaging films and bottles. R-PET is recycled PET material, which is obtained from post-consumer PET products or PET manufacturing waste. Recycling PET helps reduce environmental impact by reusing plastic and reducing the need for virgin plastic production. ETO sterilization is a widely used method for sterilizing medical devices, pharmaceutical products, and certain types of packaging materials. It is effective in killing microorganisms and ensuring the sterility of products. ETO gas penetrates packaging materials, making it suitable for sterilizing products inside sealed containers, including films used for medical packaging. ETO-sterilizable R-PET films offer a sustainable and sterilizable packaging solution, combining the benefits of recycled materials with the ability to maintain sterility in sensitive applications. These films are designed to withstand the ETO sterilization process without compromising their physical or barrier properties, making them suitable for use in medical and healthcare packaging where sterilization is crucial.
