Description
Polyethylene terephthalate (PET), produced from ethylene glycol and either terephthalic acid or dimethyl terephthalate, is commonly used as packaging material for drinking water, mineral water, carbonated beverages and edible oils. The strength and permeability properties of PET, its resistance to chemicals and its high degree of transparency are the main factors that make it more applicable. Migration from packaging materials into products generally is concerned with minor constituents that influence the quality of the contained product by sensory or toxicological hazards. In Indonesia, BPOM has stated in PerBPOM No 20 in 2019 the specific migration limit for Ethylene Glycol is 30 mg/kg (ppm) and Diethylene Glycol is 30 mg/kg (ppm).

How can SIG help?
SIG laboratory can test the migration of ethylene glycol and diethylene glycol using a food simulant to ensure that there are no residues in your PET product and ensure that you comply with the regulations set by our country

Method of Analysis
The analysis for migration of ethylene glycol and diethylene glycol is carried out using a gas chromatograph.
