Don't let food packaging materials delay the retreat of enterprises

no matter how strong the awareness of food packaging of enterprises is, the disadvantages of packaging in the market are endless: there are luxury packaging, such as gift moon cakes; There are silly packages that cannot be laughed or laughed at, such as the ring ham that cannot be peeled off; There are huge packages that are difficult for people, such as 500 grams of monosodium glutamate; There are impending immoral packaging, such as Tetra Pak pillow milk with four hard and sharp corners. The most frightening thing is that eating toxic packaging that shortens life

under the background that potential food safety hazards have become the largest factor in reducing the safety factor of citizens, consumers have increasingly high requirements for food packaging. Relevant data show that long-term consumption of food in toxic packaging may lead to various diseases, such as gallstones, heavy metals, benzene poisoning, etc. Recently, a survey of European consumers showed that consumers are more inclined to buy glass containers for food and beverages. The reason is that the vast majority of consumers (88%) believe that glass containers are more conducive to human health and more environmentally friendly

it is no exaggeration to say that food packaging has become a powerful weapon for food enterprises to dominate the market. It is not a secret weapon of anyone, but a sword to fight on the battlefield! Enterprises only have to grasp the skill of packaging, and do not let it delay the retreat of enterprises. So, how can we invest in the interests of consumers and make our products healthy and environmentally friendly? This is a matter of material selection

since 2005, China has received early warning notices from foreign countries about the presence of toxic and harmful substances in packaging containers and packaging materials of China's exported food, mainly focusing on the problem that toxic and harmful substances such as heavy metals, benzene, microorganisms and sulfur dioxide exceed the standard. Food packaging must be careful in material selection, otherwise it will cause safety problems. For example, soymilk products with poor barrier properties will be shortened. The company also plans to issue two more products before the end of the year. The shelf life of the two products will cause deterioration. For fresh-keeping film, if there is no appropriate amount of ventilation, 1 The quantity of verification items cannot guarantee the freshness of vegetables. Therefore, in the face of a large number of soft plastic supply varieties, it is particularly important for enterprises to choose a packaging material with the best performance on the machine and the safety of consumption

generally speaking, food packaging performance mainly includes the following points: first, barrier performance. That is, the isolation performance of materials to oxygen and water vapor. At present, many food deterioration phenomena are caused by the inadaptability of the barrier of packaging materials; The second is mechanical properties. It includes tensile strength, breaking force, peel strength and puncture resistance; The third is heat sealing performance. Due to the formulation of materials, the heat sealing performance of packaging materials is often unstable, which is manifested in the change of heat sealing strength of materials under the same heat sealing conditions, resulting in false sealing; Last but not least, food packaging materials must be harmless to human body. Therefore, in the initial stage of selecting materials, enterprises must carry out various performance safety tests on food packaging materials. For different foods, the requirements of materials are different. Polyethylene, polypropylene, polyester, polyamide and other polymer materials will show great differences due to different molding processes and additives. In addition, specific packaging materials 6 The quality of electrical equipment should also consider the functions of protecting commodities, meeting the requirements of display and sales, accounting of packaging costs and recycling

in the initial stage of selecting materials, enterprises must also carry out various performance safety tests on food packaging materials. For different foods, the requirements of materials are different. Polyethylene, polypropylene, polyester, polyamide and other polymer materials will show great differences due to different molding processes and additives. In addition, specific packaging materials should also consider the functions of protecting commodities, adapting to the requirements of display and exhibition, and considering the accounting of packaging costs and recycling and other factors

in fact, food packaging is a deep knowledge. For enterprises, in addition to health and environmental protection, there are more requirements, including color, pattern, selling point, material, cost, specification, cost performance, preservation, display, shipment and storage. In addition, it is important to take full account of the convenience and habits of consumers
