Green food craving for green packaging

Today, there are more and more types of green food on the market. From milk, vegetables, fruits, to food, processed foods, etc., green food has gradually entered the lives of some people. However, many green foods do not have green packaging. Pay attention to the fruits and vegetables in grocery shopping malls. Although there are some foods that use degradable containers and cling film for “green” packaging, there are still many foods that use only disposable foam plastic trays and transparent plastic packaging. The film or PVC plastic packaging bag looks very nice, but does not match with the green word, so that the meaning of "green" is compromised.

All along, due to the immature conditions in various aspects, there is no uniform requirement for the product packaging of green food production enterprises. The outer packaging of green products can only meet the national common standards for food labels. Most green foods in real life do not use green packaging, and some green food packaging does not meet the general standards, and even use some toxic and hazardous substances for packaging.

According to relevant experts, at present, there are still improper phenomena in the production, processing, and use of food packaging materials in China. There are many phenomena in the use of paper for packaging in foods, such as in the food industry, including green foods (such as carton milk). Whitened paper for food packaging. However, in order to improve the whiteness of paper during the production process, most papers are treated with fluorescent whitening agents. Fluorescent whitening agent is a chemical substance with strong carcinogenic activity. Although it can play the role of bleaching fiber, it also has a great toxic effect on humans and animals.

Second, the ink contamination of food packaging paper is also very serious. At present, many companies like to use colored wrapping paper to package food (such as milk, although the color ink is printed on the outside of the food packaging paper on one side, but the colored paper after printing is bundled together, and the non-printing surface of each packaging paper is also in contact. Ink, even if it is paraffin wax-colored waxed paper, will not be uniform because of wax coating, color inks still have direct access to food. Therefore, the use of paper on food packaging does not indicate that it is safe. There are many advanced food packaging. All of them use tin foil, and it is understood that 60% of the lead in the tin foil exceeds the allowable indicators of health, and lead is recognized as the “culprit” causing acute and chronic heavy metal poisoning.

In addition, green foods are packed in plastic bags, such as food and vegetables. According to experts, some plastics add plasticizers and antioxidants to improve performance. These additives are often toxic. Polyvinyl chloride is also a commonly used plastic, but additives are used in its production. For example, dibutyl phthalate is used as a plasticizer and chronic lead poisoning can occur in foods packaged with this type of food. In addition, polyvinyl chloride products will slowly release hydrogen chloride gas (HCI) at high temperatures (eg, above 80° C.), which is poisonous. Therefore, PVC should not be used as a food packaging material.

The United States and other countries of the environmental community to reduce packaging waste contaminated with comments made in three areas: First, should be no or little use packaging; the second is the packaging should be recycled; the third is where it can not be recycled biodegradable, does not endanger public surroundings. Fresh-keeping bags made of oxygen-removing materials on the inner walls of containers and lids developed by the United Kingdom and Germany are used to “eat” excess oxygen in the containers through these oxygen-removing materials to achieve preservation and prolong the shelf life of fruits and vegetables. At present, there are paper packaging, biodegradable plastic packaging, and bio-packaging materials that are popular in the domestic and international markets and the “green packaging” advocated by consumers. In China, edible liquid fresh-keeping film for fruits and vegetables has been used for fresh-keeping of fruits and vegetables. The domestic green packaging technology has reached the international advanced level. Therefore, to ensure the popularity of green packaging that is truly “green” and healthy, it is not far from our lives.
