The bags in the box are often made of recycled plastic from the receiver
In ancient packaging design, in order to make the package more beautiful, indecent and corrosion-resistant, a small amount of data with coating was used. This not only brought difficulties to the acceptance and re application of the scrapped data, but also made most of the coating itself toxic. If people ate the food in these packages, It will do great harm to people's body. Other coating and plating processes also bring great purification to the situation. For example, toxic solvent gas volatilized from coatings, waste liquid containing chromium and other heavy metals occurred during electroplating, and waste residue purification. Therefore, packaging materials without coating and coating should be selected as far as possible.
The data of high barrier function of packaging can not only satisfy the requirements of high barrier for drinking water and domestic fruit juice, but also meet the requirements of aseptic preservation, non-toxic and non purification. Because the soft packaging materials of bag in box are soft and light film as inner bag and corrugated paper sheet as outer carton, the package is close to the body, the weight of packaging information is small, the effective space in the package is small, the smooth transportation of goods is very convenient, and the storage and transportation cost is much lower than that of the goods with rigid packaging. The package of drinking water in the box is easy to use. When the valve is opened, the switch is free; after the valve is opened, air can not enter, which can meet the health requirements of ancient people and significantly improve the quality life of drinking water.
