Will Frozen Food Packaging Bags Ever Rule the World?
According to the market research report of China's frozen food industry, there are two kinds of frozen foods sold by merchants: one is in bulk; the other is in bags. The bagged frozen foods, as the name suggests, are packaged in frozen food bags, which are quick-frozen foods that are not packaged in frozen food bags for retail sale. The more popular may be the latter, because this frozen food saves the cumbersome packaging, reduces the price of the food, and buys more and buys less, is convenient and convenient, and is very popular among consumers, so whether it is in the supermarket or in the supermarket Markets are very common; bulk frozen foods mainly include pasta, meat, pickled products, cakes, etc., with a wide variety. However, the packaged package contains various information such as ingredient list, production date and shelf life, and the price is higher than that of bulk. In bulk, they are all in the streaking state. The glass door of the freezer can be taken freely, and the frozen food in the freezer has no information except the price and name. Therefore, in terms of food safety, the wide application of frozen food packaging bags will definitely be the trend of the current and future industry development.
With the rapid development of supermarkets and chain stores and the formation of cold chain, frozen foods are more and more popular. According to the statistics of relevant departments, the annual output of frozen food in China has reached 6.5 million tons, and it is increasing at a rate of 25% per year. The per capita annual consumption is close to 10 kg. Therefore, because of the increasing popularity of frozen food packaging, frozen food packaging also puts higher demands on the performance of packaging materials. The basic function of frozen food packaging is from production, transportation to sales, to maintain the quality characteristics of the product, to prevent bacterial contamination and to be convenient to eat. Currently, frozen foods are packaged in two broad categories: soft and hard. The soft type is based on a plastic film. Thick and hard packaging, such as a slightly thicker paper packaging box, composite aluminum foil stamping container, etc., the former accounted for a large proportion. Nowadays, the common frozen food packaging on the market adopts the following structure: OPP/LLDPE structure can achieve good moisture resistance, cold resistance, low temperature heat sealing and strong tensile strength, etc., and the cost is relatively economical; NY/LLDPE structure can resist freezing, impact resistance and puncture. The cost is relatively high, and the product packaging performance is good; structures such as PET/LLDPE and PET/NY/LLDPE and PET/VMPET/LLDPE are also used in the frozen products, but the usage rate is relatively low. There is also a simple PE bag, such as vegetable packaging. The above several product structures are the structures in which the packaging of low-temperature frozen products in the domestic market is relatively concentrated. Our company has 20,000 square meters of garden-style independent factory, advanced packaging manufacturing equipment (automatic computer high-speed concave brush machine, fully automatic computer high-speed flexographic printing machine, automatic baler, etc.), and the plant area is designed and built according to international standard factory buildings. Clean, hygienic and safe. Moreover, our products are exported to the United States, Europe, Australia, South Africa and other countries and regions, and have won the reliance of customers at home and abroad. Therefore, the development of frozen food packaging bags is definitely good.
And because of the simple operation and convenient consumption, frozen food has gradually become the new favorite on the table of the people. The frozen dumplings and dumplings in bulk are everywhere in the supermarket: unpacked dumplings and dumplings are placed in plastics according to the filling. In the box, the consumer chooses himself and puts it into the shopping bag with a spatula. However, there are many health problems with this kind of food exposed in the air.
First of all, since there is no outer bag, no matter when the food is put on the shelf or in the process of consumer selection, human contact is inevitable and the quality of hygiene is difficult to guarantee. Secondly, due to the large contact area between food and air, it is easy to cause water to evaporate, resulting in product cracking, oil oxidation, rancidity and other phenomena, and easy to breed bacteria. Again, many supermarkets sell bulk frozen foods that are only labeled with the name, taste, and price, without a date of manufacture and shelf life. When people eat frozen food, the product is likely to have passed the shelf life. According to the state regulations, the shelf life of frozen foods is -18 °C. In general, the lower the temperature, the slower the decomposition of nutrients and the slower oxidation of fat, and the flavor and quality of the product can be stabilized for a longer period of time. However, due to the continuous picking and purchase of bulk frozen food in the supermarket, the storage temperature is difficult to maintain at -18 °C.
What's more, some small-scale workshops produce quick-frozen foods that use inferior meat and vegetables as raw materials. When stored, the bacteria in the raw materials will multiply and even produce toxins, such as heat-resistant enterotoxin produced by Staphylococcus aureus. This toxin can be destroyed at an oil temperature of 218 ° C - 248 ° C. It is easy to cause food poisoning after eating. Therefore, the emergence of frozen food packaging bags has become inevitable, because it can keep the food fresh while maintaining the temperature of the food, and with the increase in people's living standards, it will become a necessity.
Therefore, affordable food, widely used frozen food packaging bags will certainly rule the world in the future.
