Food packaging is an important part of food commodities, but China has not yet introduced relevant standards for food packaging. Every holiday, the government departments must promote the rejection of excessive food packaging, but it has repeatedly been banned. Also, for instant noodle packaging, products with a shelf life of more than 6 months should be packaged in PET film. This is an international standard, but most of our products use PP film packaging, so we can only guarantee the quality for 3 months (this is the previous standard). After expiration, it will affect the personal health of consumers. Food packaging is the “coat†of food, and its safety will have a significant impact on the safety of food. Food packaging safety needs to pay attention to the following issues: (1) Defining the storage and transportation characteristics of food There are many classification methods for food packaging, which can be divided into moisture-proof packaging, waterproof packaging, mildew-proof packaging, pneumatic packaging, vacuum packaging, frozen packaging, and retort packaging according to functions. According to the storage and transportation characteristics of different foods, choosing the suitable packaging method is the primary factor to ensure the safety performance of food packaging. For example, fried and puffed foods are prone to deterioration due to oxidation reaction. Therefore, when selecting the packaging method, the packaging performance should be considered, and high barrier packaging materials , especially packaging materials with low oxygen transmission rate, can be effectively guaranteed. Food safety during the warranty period. (2) to ensure the quality and adaptability of packaging materials Non-standard production of packaging materials is one of the main causes of food safety hazards. Nowadays, most food companies do not allow packaging companies to put their own logo on the product, which makes it impossible for consumers to identify the origin of the package. Because consumers can't supervise, food companies often use the low cost as the main consideration when selecting packaging suppliers, and related to the cost of testing, many food companies have a weak sense of safety control over packaging raw materials and processes. (3) Consider the impact of printing methods At present, most of the inks themselves contain benzene, and in order to facilitate printing, they can only be diluted with a mixed solvent containing toluene. If food packaging companies use cheaper toluene with lower purity, the problem of residue of benzene and other organic solvents will be more serious. At present, the state has promulgated relevant standards, comprehensively banned benzene on food packaging, and strictly limits the total amount of solvent residues. However, due to cost issues, many companies in the food packaging industry are currently unable to meet the corresponding limit standards. (4) Standardize the use of recycled plastics At present, China does not allow the use of recycled plastics in hard plastic packaging for food, but unscrupulous traders often use recycled plastics to produce inferior food packaging materials for personal gain. These recycled plastics have been contaminated many times and pose a great threat to food safety. In fact, if the channels and methods for recycling and recycling waste plastics can be standardized, the use of recycled plastics that meet the food packaging standards for food packaging is a good measure to save resources and reduce environmental pollution. For example, the US FDA has clearly defined PET materials. After recycling, it can be reused on food packaging.
