Product Introduction:

Due to the outstanding superior properties of PET (ethylene terephthalate), such as non toxicity, light weight, high transparency, and high strength

Non fragile, with good pressure resistance, good airtightness, and relatively stable chemical properties, PET bottles are an ideal food and beverage bag

Container loading. However, during its processing and shaping, acetaldehyde is prone to residue, and during storage, acetaldehyde can also be produced, posing a threat to human health.

The national standard GB13114-1991 for hygiene standards of PET packaging materials for food containers requires a residual acetaldehyde content of ≤ 0.5mg/kg (even 0.3mg/kg).

Coca Cola, Danone, Nestle and other companies require testing of acetaldehyde content in PET bottle embryos.

According to relevant food hygiene regulations in China, trace amounts in polyester (PET) bottles used for food and beverageacetaldehydeThe content needs to be used in the production and bottling process of beverages

gas phaseChromatography is used for daily testing, and many domestic polyester bottle and beverage production enterprises require the gas phase of the production enterprise to implement this testing process

Chromatography has high quality cost-effectiveness and good stability and reproducibility. Analysis of Trace Acetaldehyde Residue in GC-7900 Polyester Bottles of Our Company by Gas Chromatography

spectrometerBecoming a leader in testing this process, with high sensitivity, good stability, and long service life, it has been promoted in numerous beverage and bottle factories across the country

Using, achieving good results, and obtaining Coca ColaHigh praise from beverage companies such as Danone, Wahaha, and Uni President.
