With the continuous development of society, the pace of life is accelerating, and reducing kitchen labor has become a demand of people. Therefore, frozen food is favored by people for its fast, delicious and rich variety. So what issues should you pay attention to when making frozen food packaging bags? Frozen food packaging bags must meet the requirements of large circulation, from production, transportation to sales, to maintain the quality characteristics of frozen products, to prevent the pollution of bacteria and harmful substances. Taking quick-frozen dumplings as an example, many consumers no longer buy them once, many of which are caused by poor packaging, resulting in water loss of dumplings, oxidation of oil, air drying, yellowing, cracking and other quality problems.
So, what should be paid attention to in the production process of frozen food packaging bags? There are seven aspects: 1.packaging standard and regulations; 2.the characteristics and protection conditions of frozen food; 3.the performance and scope of packaging materials; 4.the food market positioning and circulation area conditions; 5.the packaging structure and materials for freezing The impact of food; 6. a reasonable packaging structure design and decoration design; 7.packaging testing.
Good frozen food packaging must have five characteristics: first, to have high barrier properties, to prevent product contact with oxygen, to prevent moisture evaporation; second, impact resistance and puncture resistance; third, low temperature resistance, even in packaging materials At -45 ° C, it is not deformed or cracked at low temperatures. The fourth is oil resistance; the fifth is hygienic to prevent the migration of toxic and harmful substances into food.
