As a convenient packaging product, convenience bags have penetrated into every corner of rural and urban areas due to their lightweight, easy processing, consumption resistance, waterproof, and convenient carrying characteristics. They have become almost a necessity for people's lives, and people rely too much on them. However, has anyone considered whether they will harm human health while bringing convenience to people?
According to the investigation, these Jinan convenience bags can be divided into types such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, etc. based on their raw materials. Convenience bags made of polyethylene and polypropylene are safe and can be used to hold food. But most convenience bags made of polyvinyl chloride are toxic. They are made from recycled waste plastic and dyes, and these convenience bags have varying degrees of evaporation residue that does not meet the standard requirements.
If food is packaged in this convenient bag, it will pose a certain risk to human health. Especially for children and adolescents in their growth stage, it will have an impact on their physical and intellectual development. So, how can we identify and use toxic and non-toxic convenience bags in daily life?
1、 Place the convenience bag in water and press it down to the bottom. A convenience bag that can surface is non-toxic, while one that sinks is toxic.
2、 Non toxic convenience bags have basically no odor, while toxic convenience bags have an unpleasant and pungent odor; If rubbed by hand, non-toxic convenience bags can make a crisp sound, while toxic convenience bags have a dull and astringent sound; Non toxic convenience bags appear milky white, semi transparent, or colorless and transparent, with flexibility and a sense of lubrication when touched. The surface has wax, which is flammable when exposed to open flames and can continue to burn after leaving the fire without any odor. Toxic convenience bags are cloudy or light yellow in color, sticky to the touch, and have a foul odor when burned.
3、 When purchasing cooked food, Dim sum and other direct food and condiments, do not use convenience bags. Purchase convenience bags to legitimate shopping malls and pay attention to checking if the markings on the outer packaging bags are complete.
4、 Refrigerator should avoid using convenience bags for frozen or refrigerated food. Instead, use cling bags, plastic wrap, or paper bags.
5、 It is prohibited to use colored convenience bags to directly hold food. Because colored convenience bags have strong permeability and volatility, once food is contaminated, it is easier for the human body to absorb.
6、 It is strictly prohibited to use toxic convenience bags to hold food, and toxic and non-toxic convenience bags should be separated during storage.
