Hygienic properties of pet food bags
Including evaporation residue (acetic acid, ethanol, n-hexane), potassium permanganate consumption, heavy metal, decoloring test.Evaporation residue reflects the possibility of leaching residues and heavy metals from vinegar, wine, oil and other liquids in the use of food packaging bags. Residues and heavy metals will have adverse effects on human health. In addition, residues will also directly affect the food's color, aroma, taste and other food quality.
The degradation performance
According to different degradation types of products, they can be divided into photodegradable, biodegradable and environmental degradation types.The degradation performance reflects the product's ability to be accepted by the environment after its use. If the degradation performance is good, the bag will break, differentiate and decompose by itself under the combined action of light and microbes, and eventually become debris, which is accepted by the natural environment.If the degradation is not good, it will not be accepted by the environment, resulting in "white pollution".
