# Food Packaging Translation Food packaging is an integral component of food commodities, playing crucial roles in protecting food, preserving freshness, and facilitating circulation. Among various food packaging methods, metal packaging, boasting advantages such as excellent structural reinforcement, airtight preservation, superior barrier properties, strong oxidation resistance, ease of transportation, and recyclability, has gradually emerged as one of the key packaging solutions. Food packaging serves to protect food from damages caused by biological, chemical, and physical external factors during the circulation process from the factory to consumers. It also functions to maintain the stable quality of food itself, facilitates the consumption of food, showcases the appearance of food, and creates an appealing image to attract consumers, thus possessing value beyond material costs. Therefore, the food packaging process is also an indispensable part of the food manufacturing systems engineering. As learned from food packaging exhibitions, food packaging can be categorized based on different criteria: - By packaging material: metal, glass, paper, plastic, composite materials, etc. - By packaging type: cans, bottles, packs, bags, rolls, boxes, cartons, etc. - By packaging method: canning, bottling, sealing, bagging, wrapping, as well as filling, assembling, sealing, labeling, coding, etc. - By product hierarchy: inner packaging, secondary packaging, tertiary packaging, outer packaging, etc. - By technology: moisture-proof packaging, waterproof packaging, mildew-proof packaging, fresh-keeping packaging, quick-frozen packaging, breathable packaging, microwave sterilization packaging, aseptic packaging, gas-flushed packaging, vacuum packaging, oxygen-absorbing packaging, blister packaging, skin packaging, stretch packaging, retort pouch packaging, etc. Machine-made paper refers to paper and paperboard produced on various types of paper machines. It is characterized by stable basis weight, good uniformity, and high strength. Machine-made paper includes printing paper and paperboard, writing, drawing, and reproduction paper and paperboard, packaging paper and paperboard, as well as household, sanitary, and decorative paper and paperboard. According to data from the National Bureau of Statistics, the output of machine-made paper and paperboard in China has remained relatively stable in recent years, reaching 136.914 million tons in 2022. With the rapid advancement of technology, in addition to protecting food from damage during transportation and extending the shelf life of food, food packaging has also been endowed with unique value propositions and specific marketing functions. Food packaging can directly link effective marketing content with brands, exerting a significant impact on consumers' purchasing behaviors. Currently, an increasing number of food enterprises have begun to focus on the development of green and recyclable packaging. For instance, some dairy enterprises have launched milk packaging products without printing, and some enterprises have used boxes made from sugarcane waste to package mooncakes... More and more enterprises are adopting compostable and naturally degradable food packaging materials. It is evident that green packaging is an unavoidable topic and trend in the food packaging industry.
