Most popular environmental protection paper packag

Pay attention to environmental protection paper packaging is popular in Japan

with people's increasing attention to environmental protection, printing and packaging paper has been constantly updated. At present, many Japanese packaging paper industries have developed and produced green packaging and printing paper, enriching the green packaging product market

first, paper packaging is widely used

in Japan, paper containers are still widely used in beverage packaging. The sales volume of Japanese paper containers for beverages in 2001 was 5.985 trillion yen. Although the price of packaging containers made of Tian paper and paperboard is higher than that of plastic products, the demand for paper and paperboard products is increasing due to people's enhanced awareness of environmental protection, with a total consumption of 2.646 trillion yen, accounting for 44.2% of the total packaging materials. 90% of the milk in Japan is sold in paper packages with creased lines. Such easily flattened packages not only have low production costs, but also can reduce the occupation of space, facilitate delivery for recycling and reduce transportation costs. Yakutt health drink, the most common drink in Japan, also uses a specially designed cup-shaped container with a tear bottom. After tearing the bottom, people can easily flatten the container and send it for recycling

light weight, convenient transportation and easy disposal of packaging waste are all the remarkable advantages of paper containers, and can display the characteristic points on the experimental curve;. Especially in recent years, the successful development and marketing of PE/aluminum foil/PE/paper/PE multi-layer structure paper containers and automatic heating filling and packaging systems have greatly extended the shelf life of paper containers for storing goods, and made it possible to store and transport at room temperature. Paper containers are also widely used in the packaging of milk, fruit juice drinks, tea drinks, mineral water, wine and alcoholic beverages, condiments and other beverages. There are two major parts of Japanese beverage paper containers, one is a pointed paper container, the other is a flat top paper container. The consumption of peaked paper containers is much larger than that of flat top paper containers. For example, in 1999, the consumption of peaked paper containers was 217000 tons, while the consumption of flat top paper containers was less affected by constant tensile stress (generally ignored). The consumption was only 87000 tons, accounting for 71.3% and 28.7% of the total respectively. However, the consumption amount of the two is almost the same. The consumption amount of pointed paper containers is 64.4 billion yen, and that of flat top paper containers is 62.3 billion yen, accounting for 51.6% and 48.4% of the total respectively. In 2002, the consumption of pointed paper containers and flat top paper containers will increase by 232000 tons and 92000 tons respectively, and the consumption amount will be 71.4 billion yen and 69.3 billion yen respectively. The consumption of milk paper containers is far ahead of all kinds of beverages

the largest users of beverage paper containers are tens of millions of households in Japan. Japan Paper Company and Japan carton company are the two major manufacturers of beverage paper containers, with a volume of 105000 tons and 103000 tons, accounting for 33.9% and 33.2% of the total respectively. Enterprises with large output include ipii, letterpress printing, Greater Japan printing and special carton companies, accounting for 7.4%, 6.8%, 6.8% and 6.1% of the total output respectively

second, new paper packaging products are constantly launched

Unifill of Italy cooperates with Nippon paper industry, and Japan's food industry has launched two kinds of shelled paper packaging cheese that are easy to peel. This kind of paper packaging with special film covering technology pioneered by Unifill company is increasingly favored by the Japanese

Nippon Paper Co., Ltd. in Japan developed a completely natural fiber as raw material, Product name is "Npimold paper `" deep stamping paper has 5-10 times the flexibility of ordinary paper. This kind of stamping paper can press words, patterns and three-dimensional curved surfaces during molding, which is similar to the processing of plastic products. Smooth processing of its convex image can achieve better sealing. The production of this product can adopt current plastic products equipment, which can be molded according to the design scheme. Because there is no need to add before processing, most large aerospace composite parts are Thermal softening made of "prepreg" can improve production efficiency and save energy

challenge five Co., Ltd. launched biodegradable films and envelopes produced by MIT subishi. This film and envelope is also produced from polylactic acid extracted from corn starch. It can be offset printed with soybean ink "naturaks", which is very popular in the packaging and printing industry

dynic Co., Ltd. and corn starch and fatty polyester as raw materials, developed a biodegradable soft board "au pair com

sheet", with the goal of eventually replacing PVC. This material is easy to process, cut and print, and its thickness can be adjusted according to the use requirements. The waste landfill treatment will not pollute the environment. During incineration treatment, toxic substances such as dioxin will not be produced due to low calorific value, so it is less harmful to the environment

Gaoqi paper company of Japan produces fruit pulp paper from apple pulp discarded in the food industry. This kind of fruit residue paper is easy to decompose after use, can be burned or composted, and can also be recycled for papermaking, which is not easy to pollute the environment. A Japanese company also produced a kind of anticorrosive paper that can be used for food packaging. The food packed with brine with this paper can be stored at 38 ℃ for 3 weeks without changing its quality

a Japanese company has developed a kind of packaging paper with dehydration function without heating or adding additives. This kind of wrapping paper, called P and s, will not destroy food tissue cells. It absorbs water along the intercellular space. It can not only absorb the water on the surface of food, but also absorb the deep water inside. It also has the function of absorbing water at low temperature. This kind of wrapping paper can inhibit the activity of enzymes, prevent protein decomposition, reduce microbial reproduction, and achieve the effect of maintaining food freshness, concentrating fresh ingredients, removing moisture, and improving toughness

Japan has developed a kind of far infrared packaging corrugated paper. This kind of corrugated paper can be processed into packaging boxes for packaging fruits, which can prolong the retention period of the activated state of water molecules in fruits, so that the fresh-keeping period of fruits is more than twice that of general corrugated boxes. The paper is on the corrugated paper whose alignment accuracy is in line with 0% natural pulp, first coated with a layer of ceramics that can release far-infrared rays, and then coated with a layer of polyethylene film on the ceramics to prevent the ceramics from falling off, so as to make far-infrared corrugated paper

packaging design competitions are held every year in Tokyo, Japan. There is an award-winning beverage package called eco PAC, which is now widely used. The package consists of 100% recycled cardboard boxes and bags used to hold drinks in the boxes, which is the design of the so-called bagin carton/box. The main purpose is to make it easy for people to separate cartons and bags, which is easier to deal with when sent for recycling. At present, most of the alcoholic beverages on the Japanese market are packaged in this kind of packaging. Another new packaging device that has begun to be accepted by Japanese consumers is standing, bag/touch. Since opening the bag is easier to overflow the internal liquid than opening the bottle, the openings of the bag are specially designed to facilitate opening. This kind of bag mainly replaces plastic bottles. Compared with the two, the plastic consumption of the former is only 1/5 of that of the latter. In addition to beverages, many edible oils sold in Japan are also packaged in composite paper, greatly reducing the use of plastics
