According to reports, scientists from the Federal University of Viçosa, Brazil, have recently developed a new type of food packaging material that can extend the shelf life of foods and reduce the intake of consumer preservatives. The plastic film containing anti-microbial agents developed by researchers at the university can gradually release preservatives into foods within a certain period of time. This not only ensures the quality of foods, but also can solve the problem of consumers' intake of more preservatives at the beginning of shelf life. The problem. Researchers used bread and sausages to make satisfactory results. After 15 days of preservation of the bread wrapped in new packaging paper, no microorganisms were still born. Using the same principle, antiseptic plastic bottles were tested, and natural preservative packaging materials were planned to be developed.
A Swedish company currently develops and develops a new type of green packaging material called TPR. This packaging material is suitable for a variety of processing operations such as hot press molding, blow molding, injection molding, and extrusion molding. According to reports, this TPR packaging material is made of calcium carbonate bonded to polyolefins through a special process. Its structure is very similar to that of egg shells. It contains 95% of calcium carbonate and the remainder is polypropylene as a binder. Due to the extremely rich calcium carbonate resources, the raw materials for the production of this TPR green packaging material come from a wide range of sources and its waste is environmentally friendly.
German scientists recently developed a low-cost multilayer barrier film. Compared with conventional multilayer barrier films, the use of non-adhesive multilayer films significantly reduces production costs and improves product performance.
The new technology uses adhesive and structural (or barrier) resin blends as raw materials to produce a three-layer plastic film without a bonding layer, replacing the previous 5- and 7-layer films.
Non-adhesive layer barrier film is mainly used in milk packaging to prolong the shelf life of milk and prevent contamination of milk.

The world's first lipstick was discovered in the Sumerian city of Ur about five thousand years ago.
The ancient Egyptians would use black, orange, and purple lipsticks; in ancient Rome, a lipstick called Fucus was made of purple-red mercury-containing plant dye and red wine sediment.
Guerlain of France introduced tube lipsticks to the United States, mainly for a small number of nobles. The first metal tube lipsticks were produced by Maurice Levy and Skorwell Manufacturing Company in Waterbury, Connecticut, USA. and the Scovil Manufacturing Company) was manufactured in 1915 and is a popular product.
Lipstick development trend
In recent years, the use of various pearlescent powders and processed pigments has made lipsticks more diversified and more comfortable in texture. Similar to the development trend of other types of beauty cosmetics, lipsticks continue to maintain the focus on beauty; taking into account the functions of moisturizing, nourishing and sun protection.
Precautions
Keep the lipstick at room temperature and avoid high temperature in the storage place. The lipstick can be stored for three years before it is opened, and the shelf life is shortened to one to two years due to the contact with oxygen after it is opened. When the color of lipstick changes or emits a peculiar smell, stop using it.
