Explore the development trend of the packaging industry in the United States (II)

important packaging concepts formed

1 Environmental protection

in recent years, the United States has vigorously advocated waste paper recycling, which has achieved remarkable results. It is reported that the e-cubetm packaging material recently produced by the American E-TECH products company is made of recycled waste paper, which looks like a square. After filling, it can make vulnerable goods such as eggs not move in the box and avoid cracking. Compared with foamed plastics, e-cubes are more convenient in filling, and can fill goods of any shape, recyclable, biodegradable and non-toxic. Longview fiber company of the United States recently launched a high-quality retail packaging paper bag with handle, which can be printed in three to four colors. It is produced from recycled kraft paper bags, which are divided into Kraft color, bleached and other colors. Although this kind of paper bag is more expensive than plastic bag, it has a long service life and can compete with it

biocope company in the United States is a manufacturer of material synthesis and biodegradable materials. Recently, it took the lead in launching water cups made of plastic PLA polymer materials synthesized from grain. This product was first provided to the Sydney Olympic Games and has been put on the American market and is very popular. The company said that the physical properties of the cup made of this new material can be comparable to that of petroleum synthetic plastics, but its environmental protection performance cannot be compared with that of petroleum synthetic plastics because it is derived from plants and can be completely decomposed. It can be thrown away with food waste without any treatment. The cup can be decomposed into water, carbon dioxide and organic matter together with food waste

2. Diversification

take the food industry as an example. As Americans' demand for food consumption is changing in the direction of multi specification and diversification, the food processing industry has invested in the development of more flexible and flexible packaging. It usually takes two years to develop a new packaging product. Now it only takes half a year for the product to go on the market. This fully shows that the U.S. packaging industry develops new varieties and products quickly and in a short time. At the same time, the packaging industry is committed to providing consumers with more convenient packaging. According to the prediction of the U.S. Census Bureau, the United States will enter an aging society by 2025. Taking full account of the potential demand of elderly consumers for packaging products, the U.S. packaging industry has begun to develop packaging that can adapt to the characteristics of the aging society in the future, such as zipper closure, easy to open metal top cover, double finger pull ring, etc

in order to make food packaging convenient and beautiful, easy to open and store, enterprises continue to introduce new food packaging products to the market. Polypropylene/Acetaldehyde vinyl alcohol/polypropylene material is used at the edge of small food packaging, which is easy to open; The fast-food sweet bread is packaged in polyester film and placed on plates made of solid bleached kraft cardboard, which can solve the problems of local baking, labor-intensive and uneven quality in the past, and also extend the shelf life. The plates made of solid bleached kraft paperboard have a coating that can prevent grease from overflowing, which can withstand both the high temperature of the baking oven and the low temperature of post-treatment cooling

in order to ensure the safety of consumers, anti-theft open mouth packaging tends to be used for a variety of products. The American pharmaceutical industry was the first to adopt anti-theft open mouth packaging. Now this kind of packaging to ensure product quality and safety has been applied to food processing industry, dairy products, beverages and other packaging

3. With the use of flexible packaging on cars, about% of consumer goods in the U.S. market today appear in the form of flexible packaging. The survey shows that flexographic printing accounted for 75% of the flexible packaging market of film materials in the United States in 1996, 85% in 2000 and 95% in 2002. According to the "2002 industry status report" of the flexible packaging Association, the flexible packaging market is an industry worth US $20billion, accounting for 17% of the total packaging market of US $114billion, becoming the second largest sector of the packaging market, while the flexible packaging industry market of paper products processing in the United States is still the largest so far. The influence of structural parameters on the properties of self reinforced monopolymer composites in mold the flexible packaging industry has many growth areas, such as shrink tube packaging, sterilization soft bags, vertical bags and food packaging

A report of FPA believes that the market prospect of flexible packaging in the United States is very broad. The report points out that before 2005, there were three major markets with the most development potential in the United States: first, fresh agricultural products: at present, half of agricultural products have adopted flexible packaging, but it also points out that some agricultural products will develop towards sterile packaging due to the improvement of refrigeration equipment and technology. Second, pharmaceuticals: Although blister packaging does not belong to complete flexible packaging in a sense, but the aluminum foil or adhesive layer in the top area belongs to this packaging scope, its development momentum is rapid. For surgical equipment, soft packaging tends to be more standardized and cost rationalized than hard packaging. Third, the food market: the pet food market is one of the highlights. The production and consumption of beer in the United States has been the largest in the world for many years, with 2325 tons in 2000. The consumption of plastic bottles has increased rapidly in recent years, and glass bottle packaging has also increased in recent years, because the proportion of high-end beer has increased significantly. In recent years, due to the rapid development of PET bottles, the proportion of metal canned soft drinks in all soft drinks has declined, from 55% in 91 to 48.3% in 99. The consumption of glass bottles has also decreased significantly, from 12% of the total beverage bottles in 90 to 0.8% in 99. Soft drink packaging in the United States is made of metal cans and pet. The exhibition organizers themselves are also constantly exploring and learning from experience, but PET bottles have a broader prospect. Among other beverage containers, PET bottles grew the fastest, from 11.4 billion in 1992 to 24.2 billion in 2001. The number of glass bottles decreased from 14.2 billion in 1992 to 8.2 billion in 2001. In addition, three-dimensional bags used for beverage product packaging are also growing rapidly

packaging equipment and its development trend

1 Packaging equipment

packaging automation operation procedures have been widely used, such as PLC equipment, data collection systems, etc. In order to cater to consumers, the packaging industry in the United States tends to use a large number of information labeling systems. Because the government requires packaged products to be marked with nutritional ingredients, instructions and bar codes, the labeling system is developing towards multifunctional information

American scientists have developed a new integrated circuit inspection bag 3-angle detector, which can measure the deterioration time of a certain food or beverage. This new device for food quality detection is composed of a sensor and a scanner. Its energy comes from the radio waves emitted by the scanner. The main material of the sensor is lead. When packaging food, it is placed in the food box together. When testing, the inspectors only need to aim the scanner at the food to emit radio waves. The radio wave signals emitted by the scanner will make the food vibrate and send out music scores at the same time, The music score wave is first reflected on the box wall of the food box, and then transmitted to the sensor. By calibrating the vibration degree, vibration transmission time and music score transmission speed with a standard database, the time of the detected food deterioration can be determined instantly, and the detection result is quite accurate

2. Development trend of food packaging

most new food packaging in the United States mainly uses petrochemical products as raw materials. More and more people are willing to use plastic cans and bottles, which will replace glass products and metal products in some cases. The reason is that they are light in weight and can reduce transportation costs. Traditional fiber packaging materials have a trend of being phased out. Polypropylene film is most likely to completely replace cellophane, while translucent paper and grease proof paper will be replaced by high-density and low-density metal foil

at present, the focus of the U.S. Food Labeling industry is still on 60 # and 70 # GIS (single-sided coating) label paper, but more and more buyers of gluing label are turning to plastic synthetic materials. These plastic labels, usually polypropylene, are used in some metal cans, but they are most favored by the beverage industry and are widely used in plastic and glass bottles. Sleeve type plastic labels with heat shrinkability are applied to metal cans and bottles at the same time, because aniline printing method is both economical and satisfactory. In recent years, two major changes have taken place in the field of paper labels, one is the demand for UV curing outer coating, and the other is the use of a wider range of ink colors. Many printing plants can print nine colors at a time, and printing more special colors only costs a little money
