Customer question: Is the food bag biodegradable?Excellent answer:Food-grade plastics are generally non-degradable. Food-grade plastic packaging is generally not produced with degradable plastics because it is in contact with food and should meet the shelf life requirements of food, and degradable plastics are added with biodegradable materials or photolytic materials. Its appearance is not very good (such as poor transparency, gloss, etc.) does not meet the appearance requirements of food packaging. This type of plastic will degrade, but it takes a long time to degrade, so it is not considered an environmentally friendly plastic from an environmental point of view.Under normal circumstances, when the plastic bag is produced, the distance from the bottom3arrive5At centimeters, a logo will be printed (some manufacturers print it elsewhere), a triangle logo. There are numbers in this logo.
