The BS EN 16068-2011 standard specifies the technical requirements for PET film 38 in rigid plastic containers. It is suitable for 38 mm diameter rigid plastic containers coated with PET (polyethylene terephthalate) coating. It is widely used in food and beverage Encasement. The standard details the performance requirements of PET film, including film adhesion, temperature resistance, transparency, mechanical strength, etc., to ensure its Stability and safety in practical applications. Through the implementation of this standard, the mass assurance level of film containers has been improved, which helps to standardize the Encasement industry, ensure compliance with the requirements of the international market, and promote technological progress and material innovation.
