Most paper cups available on the Chinese market would not meet the new national standard, which comes into effect on June 1, according to industry insiders. The country's first regulation on disposable cups will focus on raw materials, additives and printed patterns, and is aimed at boosting consumer safety. However, as the new rule does not include details on any penalties for offenders, experts predicted on Monday that the standard is unlikely to have a major impact in the short-term. "Most cups, not only those served at small, roadside restaurants, but also those provided by big-name catering companies, will be substandard once the national standard comes into force," said Dong Jinshi, executive vice-president of the International Food Packaging Institute in Beijing.
