Starting from two methods to do a good job of packaging roll film products
（1） Understand the characteristics of food and determine the required protection conditions
In order to do a good job of food packaging film, first of all, we should understand the main ingredients and characteristics of food and the internal reactions that may occur in the process of processing, storage, transportation and circulation, including abiotic internal biochemical reaction and biological spoilage reaction mechanism. Secondly, we should study the sensitive factors that affect the main components of food, especially the nutritional components such as fat, protein and vitamin, including light Oxygen, temperature, microorganism, physics, mechanical mechanics and other factors. Only by mastering the biological factors of packaged food and determining the required protection conditions, can we correctly select packaging materials and packaging technology
（2） Study and master the packaging performance, application scope and conditions of packaging film materials
There are many kinds of packaging materials with different properties. Therefore, only by understanding the packaging properties of various packaging film materials and containers can we choose the packaging materials which can not only protect the food flavor and quality, but also reflect its commodity value, and make the comprehensive packaging cost reasonable. For example, low temperature resistant food packaging materials should be selected. www.dgbpk.com/
