Ancient packaging origins
By 2000 BC, China was using pottery as food containers, while the Greeks used wooden barrels to transport food by 1000 BC. During the Northern and Southern Dynasties of China (AD 557), there are records of duck meat wrapped inus leaves, a natural packaging that combines preservation and medicinal functions.
Industrial Revolution breakthroughs
The invention of tinplate cans by British Durand in 181 and the patent for tin-coated steel cans in 1812 drove the commercialization of canned food. In 1861, British law allowed manufacturers to printed packaging, marking the beginning of branded packaging.
Modern material revolution
The application of plastic film in the early 20th century and the introduction of multi- composite flexible packaging technology from Taiwan in the 1960s. PET bottles in the 1970s and nanomaterials in the 1980 have promoted the development of packaging towards lightweight and functionalization.
Contemporary innovation trends
Packaging bags are becoming increasingly intelligent and environmentally friendly. Smart packaging indicates food fresh through color changes, such as oxygen-sensitive packaging bags developed in the UK. In the field of environmental protection, there are rice-based degradable bags that decompose naturally within100 days. Single-material packaging bags are 100% recyclable.
