Polyester mainly refers to polyethylene terephthalate(PET),Traditionally, it also includes polybutylene terephthalate(PBT)Linear thermoplastic resins such as polyarylesters. It is a type of engineering plastic with excellent performance and wide applications. Due to its non-toxic, lightweight, high transparency, non fragility, good pressure resistance, and relatively stable chemical properties, it is widely used in food and beverage packaging containers. However, during its processing and molding, it is easy to cause residual acetaldehyde, which can be harmful to human health. national standardGB13114-1991The hygiene standard for polyethylene terephthalate resin used in food containers and packaging materials requires that the residual content of acetaldehyde should be ≤0.5mg/kg (even0.3mg/kg)Coca Cola, Danone, Nestle and other companies require testingPETThe acetaldehyde content of bottle embryo seeds.

According to relevant food hygiene regulations in China, polyester is used for food and beverages（PET）The trace acetaldehyde content in the bottle needs to be detected by gas chromatography during the bottling process of beverages. Many domestic polyester bottle and beverage enterprises require their gas chromatography to have high quality cost-effectiveness, good stability, and reproducibility in order to implement this verification process. Our company'sGC-9860Analysis of Trace Acetaldehyde Residue in Polyester Bottles by Gas ChromatographyBecome a leader in testing this process and promote its use in numerous beverage and bottle factories in * * * *, achieving good results..
