Technical field
The invention belongs to special paper products technical fields, and in particular to a kind of preparation method of Mixidene.
Background technology
Food packaging is the important component part of food industry, can be in the matter for storing with keeping food in transportational process
Amount and safety, and by preventing unfavorable factor or condition from extending the shelf-life of food.Therefore, packaging material provides object for product
Suitable physical and chemical condition is protected and created to reason, this is for obtaining satisfied shelf life and keeping food quality and safety
It is most important.Other than should have the basic performance of packaging material, should also have some prevents water vapour, oxygen for food packaging
The performance that gas, carbon dioxide and other volatile compounds penetrate.
Moisture control is the important component of food packaging, and in some cases, increased moisture can be led
Food spoilage is caused, and in other cases, the loss of moisture is exactly the reason of food requirement of sense declines.When the presence of moisture has
It can lead to unnecessary chemical reaction and promote the growth of certain micro-organisms；And the loss of moisture also can especially influence the matter of food
The variation of ground and appearance, relative humidity can lead to food surface lack of moisture, lead to many irrational mix defects, such as go out
Now caking, crystallization or viscosity etc..The increase of moisture may also occur due to food in packaging, some water content are higher
Food is for example, vegetables and other fruits and vegetables tissues can release moisture in respiratory.Therefore, food and surrounding are avoided or reduced
Dehydration between environment and water transport, for most important in terms of food quality and safety.Food paper packing material must
It must be according to the demand of packaging food, it is ensured that proper water vapor transmitance extends food to keep the balance of moisture in pack environment
The storage time of object.
