Green Packaging: The Choice of Healthy Living

Since the development of human society today, there have been rapid changes and rapid changes. Advanced science and technology and productivity promote the continuous advancement of social ruts. Human spiritual civilization and material life have been unprecedentedly improved. Some people say that human life should be proportional to the advancement of medical care. This statement seems superficial, but it is not entirely true. In my opinion, whether food eaten by people is the key to human longevity. In today's society, humans are pursuing green foods. Many food packaging packages will also be labeled as green foods. It seems that human health is guaranteed. Wow, sad! This is far from enough!

Let us think about the food we eat every day. People today must keep up with the pace of the times and be so busy every day. TAKEN AWAY FOOD became the first choice for people in the morning. And those foods are usually placed in simple plastic bags without any health guarantee. I have seen news on a television about the plastic bags used by a manufacturer. The manufacturer cleaned the recovered plastic grass and used the plastic to produce a new batch of plastic bags. Most of these plastic bags are used in fast food or food bags. These plastic bags are naturally unsanitary. Therefore, in real life, we should try to avoid plastic bags directly containing imported foods, mainly for the sake of our health.

Not only plastic bags, many plastic containers filled with polymers are harmful to health. 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. Foods packaged with this material may cause chronic lead poisoning. In addition, polyvinyl chloride products slowly release hydrogen chloride gas (HCI) at high temperatures (eg, above 80° C.), which is toxic. Therefore, PVC should not be used as a food packaging material. The most typical plastic application is the annual moon cake packaging. In fact, most of the moon cake packaging uses transparent plastic packaging every year, which is both beautiful and reduces the cost of moon cake manufacturers. However, these manufacturers have never considered from the perspective of human health. I advise consumers to be cautious when purchasing plastic-packaged foods.

At present, the use of paper for food packaging in China is also a relatively large phenomenon. In the food industry, including green foods (such as carton milk), a large number of whitened paper is used for packaging. In order to improve the whiteness of paper in its production process, most of them 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 paper fibers, it has great toxic effects on people.

According to relevant sources, many companies currently prefer to package foods with colored wrapping paper. Although colored inks are printed on the outside of food wrapping paper on one side, the printed colored paper is bundled together and there is no printing surface for each wrapping paper. Can be exposed to ink. Even paraffin-waxed colored waxed paper will give color inks a chance to come in direct contact with food because of uneven waxing. There are many high-grade food packaging that uses tin foil. It is understood that 60% of the lead content in tin foil exceeds the allowable health index and is recognized as the “culprit” causing acute and chronic heavy metal poisoning.

The above facts are by no means my malicious exaggeration. Its true existence is slowly swallowing human health. The current situation shows that we should vigorously promote the application of green packaging and actively develop new products for green packaging.

In terms of plastic film, PP and POF are used as the replacement products of PVC heat shrinkable film and can be widely used in outer packaging or collective packaging of clothing, food, medicines, beverages, stationery, toys, cosmetics, paper products, daily necessities, etc.; Europe and the United States have strict environmental protection requirements for metal products, handicrafts and textile fabrics. These materials meet the US FDA and USDA standards, and do not release toxic gases during heat sealing. The waste can be recycled.

The study of replacing the existing plastic packaging with "biodegradable resin" is also underway. Corn is a delicious and nutritious food. It is also widely used in the manufacture of animal feed and sweeteners. With the development of technology, scientists have also found that using corn to make a variety of plastic products. The "corn starch resin" that has been successfully researched in Japan and China in recent times is a new type of green environmental protection material. This kind of resin is made of corn and processed and plasticized. It can be used to make a variety of disposable plastic products, such as cups, plastic bags, and commodity packaging.

U.S. Department of Agriculture food science experts have also developed a new type of environmentally friendly packaging materials. This material is completely made of crushed strawberries. This new stringent food packaging material is no different in performance from the original product. The food film made of it can also prevent the infiltration of oxygen, so as to achieve the purpose of food preservation. Because the composition of this new material is derived from vegetables and fruits that are not suitable for human consumption, it is a natural ingredient that can be decomposed. Environmentally friendly materials. In the test, the packaging film made of this magical material can not only play a role in keeping fresh, but also can improve the taste of bananas and apples and other fruits.

In our country's Hubei Wuhan Wuhan Futuo Central Packaging Materials Co., Ltd. and Wuhan Jinfeng Environmental Protection Company Plastics Co., Ltd., we have mastered the technology of pulling deteriorative grain processing into shock-proof and decompression packaging materials. Not only China's deteriorated grain has found a way out, but also successfully explored packaging materials. Alternatives. In addition, they are also able to process waste materials such as bagasse, wheat straw, and newspapers into various types of shockproof and pressure-reducing materials such as golden yellow and orange. Tests have shown that the performance of this material is not inferior to that of foamed plastics, but the weight needs further study.

Japan's Suntory company uses the gift beer packaging as a gift to the customers. The packaging box is made of wheat shells after being processed and refined. After packaging, this kind of material can be differentiated and become a kind of fertilizer, forming a kind of resource. The packer did a good job in the ecology and recycling process. In the past, under the guiding principle of unlimited resources, a model of resource → → processing → sales → use → discarding → recycling was formed to complete the following virtuous cycle:
┌Processing a sales ┐
Use of resources to recycle a waste
It takes nature. It is also natural and there is no pollution.

The newly developed Tetra Pak is also a veritable green package. This paper packaging can be recycled into "colored board" to produce furniture, flooring, toys, and audio equipment. It is produced in Sweden, where environmental awareness is very strong. Experts are now doing further research on green packaging materials.

The “TPR” green packaging material invented by Swedish experts is made of calcium carbonate bonded to polypropylene through a special process. Its structure is very similar to the eggshell, which contains 95% of calcium carbonate and the remainder is binder polypropylene. This material can be processed by various methods such as thermoforming, blow molding, injection molding, and extrusion molding. And it is smooth, smooth, and can be printed directly with a variety of colors. At present, butter and ice cream packaging products made from this material have appeared on the markets of Switzerland, Finland, the United States and Russia.

Some composites are also the preferred material for green packaging. Composite materials are two or more films that are combined to form a unitary material. This material overcomes the shortcomings of a single material, maintains the superior properties of the original material, and produces new properties. At present, there are over 500 kinds of composite materials. The development of green food composites has tended to be diversified, with multi-functional and multi-phase composite materials. The nanocomposite material (refers to the microscopic structure of the material such as the crystal and the grain boundary to reach the nanoscale level) can be said to be the latest technology product.

From the above facts, we can clearly understand that green packaging materials have developed greatly. Packaging green food with green packaging materials is a veritable green food, and it is the demand for social development. Green packaging - the embodiment of human health.
