Environmental conditions for moisture-proof packaging of self-supporting bags packaging, storage and transportation conditions and climatic conditions
According to the characteristics of packaging materials, moisture-proof packaging is mainly divided into two categories: one is moisture-proof packaging to prevent the package from losing moisture, and the other is the packaging that absorbs moisture (increasing moisture). The former mainly uses high barrier packaging materials to prevent moisture from discharging out of the package, while the latter can also add high hygroscopicity material desiccant into the package.
The environmental conditions, storage and transportation conditions and climatic conditions of moisture-proof packaging are embodied in the characteristics of the packaging materials, the required storage and transportation period, the temperature and humidity in circulation, etc. Therefore, when selecting the packaging bag, the corresponding moisture-proof packaging bag should be customized according to the specific requirements of the food.
Bag knowledge: what characteristics should flexible packaging materials have?
1. Protection performance.
Self supporting bag packaging should protect the contents, so that their performance and reliability are not affected by external mechanical factors such as impact or vibration, environmental substances such as water or air, and climatic conditions (such as temperature).
2. Operational performance.
For plastic packaging printing materials, the first thing to have printability, or through pretreatment can solve the problem of printing fastness. It is also required to have certain rigidity and stiffness, which can adapt to the automatic packaging of packaging machinery, the sealing and bag making of heat sealing machinery, and has the properties of easy filling and opening.
3. Transfer and storage performance.
The package should have a certain pressure strength, which is not easy to be damaged under general pressure in the circulation field. The shape of packing materials should be easy to stack and occupy less space.
4. Promotion performance.
The style and color of self-supporting bag packaging should be novel, the decoration and printing color should be bright and generous, in line with the interests of people in the sales area, and have market competitiveness. In addition, no static electricity is required to avoid dust pollution. http://www.dgfzb.com/
