The hottest review of international packaging in 2

  • Detail

Looking back on the international packaging in 2005, the trend of global packaging development in the past year is that the standards and regulations of food packaging are stricter, and the prohibited additives and additives are clearer. Technology and material research and development are developing in the direction of conforming to circular economy and reducing the total amount of packaging waste. Here, let's review the international packaging in 2005

food packaging has a global standard

the hottest topic in the global packaging industry in 2005 is the safety of packaged food. Based on the HACCP safety management system standard, the international organization for Standardization ISO formulated iso2200/2005 standard - "food (packaging) safety management system - Requirements for any organization in the food chain", which was officially promulgated on the official website of ISO on September 1st, 2005

EU bans badge

European and American studies have shown that bisphenol A (badge) is an "environmental hormone", which will cause harm to human health and the ecological environment even in the case of extremely low intake. Europe and the United States also strictly restrict the use of such compounds in packaging materials, organic coatings and adhesives

for this reason, the European Commission approved and issued the 2002/16/EC Directive on the use of some Epoxy Derivatives in food packaging in the spring of 2002. According to the directive, EU member states have banned the production of food can coatings and adhesives for food packaging containing these substances from December 31, 2005, and also banned products containing these ingredients from entering the EU market

biological steel

American scientists have successfully developed a new material "Biosteel" with high strength, good toughness and degradability

according to media reports, there is a kind of black spider in the southern United States, whose silk is extremely hard and tough. So the scientists conducted an interesting experiment: inject the spider's protein gene into a specially bred Brown goat, so a large amount of flexible protein fiber can be extracted from the milk produced by the goat. The cloth woven with transgenic goat milk fiber is actually much stronger than the bulletproof clothing. The research shows that this kind of milk fiber cloth has good performance when it is used for anti sprint packaging of military articles. In the future, after the cost is reduced, it may be used for civilian product packaging

anti counterfeiting label

in May 2005, German researchers developed a new anti-counterfeiting label system. The new system is a perfect combination of laser technology and packaging technology, giving full play to the advantages of thin film material data storage technology. First, the laser beam scans the anti-counterfeiting pattern and activates its light spots to store on the special polymer film. In particular, the film thickness is only 50 μ m. One million light points (pixels) can be stored per square millimeter. They can form a three-dimensional hologram to form the anti-counterfeiting logo or digital code image of the enterprise. In addition, the laser spot can also store 1000 bytes of product data information, which can be used to introduce the relevant information of the product. Finally, during the inspection, the laser hologram and product data information can be reproduced on the screen through a special reading device

functional paper

South Korea has launched an anti unpacking multi-layer packaging functional paper, which is made of kraft paper, special foaming materials, adhesives and lining paper. It has self-adhesive, shock absorption, flexibility, corrosion resistance, anti unpacking and other functions, and is mainly used for the packaging of high-grade hardware goods and handicrafts

Japan produces a new type of packaging paper that can prevent food from mildew and deterioration and maintain food flavor. According to media reports, it is made by fusing the special glyceride with other compounds, dissolving it in ethanol aqueous solution, spraying or dipping the paper, and drying it. It is widely welcomed by merchants because of its good mildew proof function and good cost performance

in addition, it is treated with special mineral shrinkage solution, which is specially used for fresh-keeping packaging paper bags of fruits and vegetables

new plastics

with the development of science and technology, fruit and vegetable skins can be used to make packaging materials. It is reported that Cornell University in the United States invented a blow molded film made of orange peel plastic, which can also be used as a new technology for many utilization technologies, such as food preservation. According to researchers, orange peel contains 95% lemon olein, and it is the best material for making peel plastic. Firstly, lemon oil essence is oxidized to make lemon oil essence peroxide; Then it is combined with carbon dioxide with a special catalyst, and finally the carbonized lemon oil concentrate polymer is prepared. The plastic properties of this product are equivalent to that of polystyrene. This technology has many advantages. First, it is rich in materials, second, it can be used for the future, third, it can help reduce carbon dioxide in the atmosphere and reduce the greenhouse effect, fourth, it is conducive to environmental protection, and fifth, it can save oil

single layer PET bottles

in 2005, polyester bottles, especially single-layer PET bottles, were the most popular. First of all, in order to meet the needs of the beer market, the United States launched a single-layer PET beer bottle, which is made of polyester material polyshield, making a breakthrough in the production technology of PET beer bottles. It is reported that polyshield is a new PET/PA blend resin, which has excellent mechanical properties, high oxygen absorption and gas barrier, as well as the color and transparency of traditional glass beer bottles. The single-layer beer bottle made with it has excellent pressure resistance and can withstand the pasteurization process of 65 ℃ for 30min. It has been tried all over the world. New Zealand has also developed a new single-layer pet wine bottle, which has been put into use on air routes. The volume of the wine bottle is 187ml, and the shape is different from that of the glass bottle, but it can be operated on the standard filling line

smart packaging

France launched an intuitive fresh-keeping package, namely "ox eye". It automatically displays the freshness of packaged food through color change. "Ox eye" is an intelligent display device, which looks like a "target". The ring in the center contains chemicals. It will polymerize with the increase of time and the change of temperature, and its color will change automatically. When the time is extended and the temperature rises, the number of bacteria in packaged food will also increase significantly, and the ox eye will automatically turn from transparent to black, which is easy for managers and consumers to identify, so it is very popular

in order to prevent the phenomenon of stealing packaged food in supermarkets, Japan has introduced an intelligent anti-theft packaging: as long as someone opens the bottle cap of the food container, the pattern on the bottle cap will change color, which is especially suitable for anti-theft eating of granular, powdery, baked and canned food. The principle is to use ferrous oxide to change color due to oxidation after opening the bottle cap

fresh-keeping packaging

France launched a new type of fresh-keeping packaging for vegetables - cobservespratiques, which can extend the shelf life of vegetables to two years, opening up a new world for vegetable packaging. I think it is the market that guides and supports e-commerce enterprises and express delivery enterprises to use green packaging products or packaging product brands that have passed the green certification of express packaging products. Convenient cans are a new type of sealed shallow dish, which is composed of 2 or 4 independent chambers. The products are filled and sealed and then sterilized at high temperature. As the outer transparent film is used for sealing, it is convenient for consumers to purchase intuitively. It is mainly used for fresh-keeping packaging of beans and mixed vegetables, and has been sold in France. Singapore also introduced a safe gas filling method last year for fresh-keeping packaging of high-end vegetables

VA company of Finland and CITA company of France have successfully developed a wine preservation bottle stopper, which is composed of TiO2 coated non-woven fabric and activated carbon, instead of cork, and makes the wine more mellow and delicious. The United States has also launched an intelligent nano fresh-keeping film

high heat resistant packaging materials

Canada has successfully developed a new high heat resistant food packaging material - PET/pen new material. It has many advantages, such as high temperature resistance, embrittlement resistance, moisture resistance, oxygen resistance, UV resistance and so on. It can be directly packaged in high temperature production lines, thereby extending the shelf life of packaged food. The key to the high temperature resistance of new materials is the addition of special substances, which was successfully developed by gueceph University in Canada, opening up a new way for high temperature packaging
