Correct use of food packaging bags
To identify toxic food packaging bags, the following simple methods can be used to identify whether plastic bags are toxic or not:
Water detection method: put the plastic bag in water, the non-toxic plastic bag can surface after being put into the water; the toxic plastic bag will not float upward.
Hand touch detection method: touch the plastic bag with your hands, those with a sense of lubrication are non-toxic; otherwise, it is toxic.
Jitter detection method: grab one end of the plastic bag with your hand, pat it hard, and those that make a crisp sound are non-toxic; otherwise, they are toxic.
Fire detection method: You can cut off one side of the plastic bag and burn it with fire. The poisonous one is not easy to burn; the non-toxic one is easy to burn in case of fire.
The correct choice of food packaging bag selection and use of qualified food plastic packaging bags should pay attention to the following points:
1. The outer packaging of food plastic packaging bags must have Chinese logos, marked with the factory name, factory address, and product name, and the words "for food" should be clearly marked. Products are accompanied by a product inspection certificate after leaving the factory.
2. The food packaging bag is odourless and odourless when it leaves the factory, and a plastic packaging bag with a special odour cannot be used for food packaging.
3. Colored plastic packaging bags (such as dark red or black currently on the market) cannot be used for food packaging. Because such plastic bags are often made of recycled plastic.
4. Try to use materials that are not coated or coated. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of materials with plating are used. This not only brings difficulties to the recycling and reuse of materials after the products are scrapped, but most of the coatings themselves are toxic. If people eat these packaged foods, it will cause great harm to people's bodies. In addition, the coating and plating process also brings great pollution to the environment. For example, the paint volatilizes toxic solvent gas, and the waste liquid and waste residue pollution containing heavy metals such as chromium are generated during electroplating. Therefore, packaging materials that are not coated or plated should be selected as far as possible.
5. It is best to buy food from the food packaging bag factory, not from the street stalls.
6. Due to the non-degradable characteristics of food packaging bags, it will cause environmental pollution. Therefore, when purchasing food, it is best to use green packaging materials. Paper is currently the most widely used green packaging material. Therefore, it is best to choose original paper packaging when purchasing food, and biodegradable plastics are also acceptable.
