Blister packaging product categories and process equipment
Looking at the overall situation, the plastic packaging bag industry still has a very good development trend in the future, and food packaging is one of the important increasing poles of plastic packaging. With the continuous improvement of the quality of life, food packaging needs to be diversified to meet the consumption needs of modern people at different levels, which has to involve the innovation of food packaging materials.

Recyclable packaging material made of amorphous polyethylene terephthalate
The Danish food packaging expert Faerch Plast recently obtained a European patent for its recyclable packaging material Mapet II made of amorphous polyethylene terephthalate for meat, poultry and fish. Praise. It is reported that the material is specially developed for fresh meat, poultry and fish in advanced sealed packaging, which can allow consumers to eliminate the risk of leakage or potential contamination during transportation. The material is made of amorphous polyethylene terephthalate. Faerch Plast adds a small amount of special adhesive to each Mapet II tray to replace the original PE layer to ensure its tightness. The adhesive is also approved for direct food contact. Lars Gade Hansen, President of Faerch Plast, said: "We are very happy to receive this award. This breakthrough product is well received in the European food market."
Can replace plastic packaging made of styrene plastic
Holfeld Plastics (Wicklow, Ireland), a subsidiary of Waddington Europe, won the Worldstar Packaging Awards for the second time in the food contact category. The winner this time is the Hydrozorb H-PE material produced by the company. Holfeld's H-PET is a pioneering case of material development and continuous product innovation-it can replace styrene plastics. It is a lightweight, low-carbon r-PET mixed with organic and inorganic fillers, changing the tradition The performance of r-PET. It has all the commercial advantages of PS and has no adverse effects on the environment. The reduction in surface tension enables packaging made of this material to extend the shelf life of perishable mushrooms and berries. H-PET material uses fewer petrochemical ingredients in its manufacturing-20% of which are inorganic fillers. After testing, this material meets the EU 10/2011 standard for food contact grade plastics. At least 50% of the other ingredients are post-use waste. By improving the ratio of weight to strength, the stability problem is also solved.
New polyethylene product series used in food packaging
American petrochemical company Exxon Mobil recently launched a series of new polyethylene products, high-performance XP polymers. These products can help processors develop new types of liquid packaging and food packaging, and can even be used to construct liners. The company claims that liquid packaging applications include stand-up packaging, bag-in-box, etc., high-performance XP polymer can produce special films, with good bending resistance and toughness, effectively preventing product leakage or contamination. In the field of food packaging, it has good sealing performance in high or low temperature environments. Cindy Shulman, vice president of ExxonMobil Chemical Plastics and Resins, said that these innovative polymers are our company’s commitment to continued growth and innovation, and we are very happy to expand our polyethylene product portfolio.
"Six concepts" help plastic food packaging become more competitive
Aseptic packaging
Aseptic packaging accounts for a large proportion of food packaging. For example, small bags of aseptic milk are cheaper, have good product flavors, and have a long storage time at room temperature. Manufacturers and consumers welcome this kind of packaging products. It not only overcomes the limitation of production area, but also removes the cold chain required in the transportation process, which is conducive to market expansion. According to statistics, liquid food aseptic packaging exceeds 70%, and more than 100 billion carton aseptic packaging is consumed globally every year. At present, there are more than 3,000 sets of various aseptic packaging equipment in China, with an annual production capacity of more than 1.5 million tons. Tetra Pak of Sweden, SIG Momeibao of Switzerland and International Paper Company of the United States are the three giants in the field of aseptic carton packaging. With the development of the economy and the improvement of people's living standards, the demand for convenience food is bound to increase greatly, which will certainly promote the further development of aseptic packaging.
Green packaging
Green packaging refers to packaging that is non-polluting to the ecological environment, harmless to human health, and can be recycled and recycled. Today, when people are extremely concerned about the ecological environment, the green packaging of food has also become a necessity. Experts predict that green food will dominate the world market in the next 10 years, and green packaging is the passport of green food among consumers, and it is of great significance for shaping green food brands.
Functional packaging
With the rapid development of packaging technology, in recent years, a number of new packaging products with unique functions and diverse varieties have been developed at home and abroad, which are refreshing and have been favored by consumers and attention by operators. Recently, the U.S. FDA has approved the application of a UV blocker to American food packaging. The sunlight and the fluorescent lamps in the warehouse contain ultraviolet rays, and the ultraviolet blocking agent added to the transparent PET packaging material of this product can effectively block ultraviolet rays and prevent any changes in the color, smell, taste and nutritional value of the items in the package. Transparent packaging materials allow consumers to understand the quality and appearance of the product. A Japanese company introduced a kind of preservative paper that can be used for food packaging. Its production process is to immerse the raw paper in an ethanol solution containing 20% ​​succinic acid, 33% sodium succinate and 0.07% sorbic acid, and then dry it. Foods with marinade in this paper package can be stored at a high temperature of 38°C for 3 weeks without deterioration.
Smart packaging
Smart packaging is usually composited with functional packaging materials such as photoelectric temperature sensitive, humidity sensitive, and gas sensitive. It can display some important parameters such as temperature, humidity, pressure, degree of sealing, and time of the packaging space. This is a very promising functional packaging. Sichuan Haodong High-Tech Co., Ltd. recently successfully developed a novel anti-counterfeiting packaging film. The advantage of this kind of anti-counterfeiting packaging film is that it is colorless and transparent, and will not affect the patterns on the packaging bags, cartons, iron boxes, and glass bottles of the goods. Under light, it can clearly show laser holographic patterns and text that cannot be counterfeited. If it is used in an automated packaging production line for commodities, the overall anti-counterfeiting effect of commodities can be more ideal. This novel anti-counterfeiting packaging film is a colorless plastic film with a thickness of generally 10-100 microns.
Convenient packaging
The convenience of food packaging is also an aspect that cannot be ignored in the development of food packaging. Consumers need packaging that is more convenient to open and seal, and they also need food packaging that can bring more convenience to life. Convenience is the new development trend of food packaging. In order to facilitate the consumption of consumers, the use of light energy, chemical energy and metal oxidation principles enables food to be automatically heated or automatically cooled in a short time to meet the needs of outdoor workers, tourists, the elderly and children. For example, the self-cooling beverage can in the United States contains a small container of compressed CO2. The volume of CO2 expands rapidly when it is opened, which can reduce the beverage temperature to 4.4°C in 9 seconds.
Personalized packaging
With the continuous improvement of the level of technology, similar products are becoming more and more homogeneous. The competition between enterprises has transformed into a competition of image power in a certain sense. Design is not only a simple visual stimulation, but more importantly, creating In the design of the information communication with the design product, the clever application of the law of color and emotion, and give full play to the suggestive role of color, can more arouse the widespread attention and interest of consumers.
