Customers need to judge whether the customized food packaging bags are suitable for their products
Food vacuum packaging bag is a common kind of packaging in plastic flexible packaging. Compared with ordinary plastic packaging bag, it has obvious advantages in packaging performance, environmental protection performance and aesthetic degree. If consumers want to accurately and appropriately select food vacuum packaging bag, what aspects should we pay attention to?
First, the outer package of food packaging bags should be marked in Chinese, indicating the name of the factory, address and commodity name, and the word "for food" should be marked in the prominent place. After the goods leave the factory, they are attached with the commodity inspection certificate.
Second, the vacuum packaging bags for food are odorless and odorless when they leave the factory. Most of the vacuum packaging bags with special smell are produced with old materials or polluted in the production process, so they can not be used for food packaging.
Third, colored food packaging bags (dark red or black and other colors used in the market at that time) should not be used for food packaging. Because this kind of vacuum packaging bag is often made of recycled plastic, and pigment may also migrate to food.
Fourth, as far as possible to choose no coating, coating data. In order to make the packaging more beautiful and corrosion-resistant, many materials containing coating or coating are used in modern packaging. This not only brings difficulties to the recovery and reuse of the invalid materials, but also most of the coatings are toxic. If you eat these packaged foods, you will have great damage to your health. In addition, the process of coating and plating also brings great pollution to the environment. Such as coating volatile toxic solvent gas, electroplating waste liquid containing chromium and other heavy metals, waste residue pollution. Therefore, we should try to choose the packaging bag without coating and coating.
Fifthly, the best choice of food to go shopping malls, not to the street stalls to buy. Manufacturers with large demand can customize these large-scale professional packaging bag manufacturers such as Cangzhou hannuo plastic packaging, and the price is more favorable than retail.
Sixth, because the vacuum packaging bag for food is not easy to degrade, it will cause environmental pollution. Therefore, when purchasing food, it is best to choose green packaging materials. Paper is now the most widely used green packaging materials. Therefore, when choosing food, the best choice of the initial paper packaging is appropriate, biodegradable plastic can also be. http://www.dgbpk.com/
