Paper packaging materials and their application in the field of food packaging

in the four pillar materials of modern packaging, paper, plastic, metal and glass. Among them, paper products have the fastest growth. Paper and plastic are the cheapest. Raw materials come from a wide range of sources, and are not as fragile as glass, nor as heavy as metal. Easy to carry

the International Health Organization and domestic environmental protection experts believe that the use of plastic food bags will be gradually banned in domestic and foreign markets, and non-toxic and harmless all paper environmental protection bags should be used for shopping in the future. Paper products are easy to decay, which can be recycled or used as plant fertilizer. It can also reduce environmental pollution. Purify the air

I. main packaging paper and paperboard

substitute wood packaging paper materials

substitute wood packaging abroad

substitute wood heavy packaging in developed countries, including the use of high-strength multi-layer (double arch) corrugated boxes (box Department); Non wood product tray (seat part): the application of non wood product materials for strengthening structural materials at the edges, corners, bottoms and tops, as well as cushioning, positioning, protection and auxiliary materials (combined filling part) for partitions, cushions and filling, has entered the stage of commercial application as early as the mid-1980s. But up to now, a certain amount of fumigated and antiseptic wooden boxes and packing boxes made of processed wood products such as plywood are still used. Its technology and equipment are of high level

commonly used substitute wood packaging paper

high strength multi-layer corrugated cardboard boxes used in heavy packaging

for small and medium-sized substitute wood cartons, generally three corrugated cardboard (generally seven layers) can be used to make heavy-duty packaging boxes through automatic production lines, which are fixedly connected with wooden pallets at the bottom of the box (and it is also very stable for the performance of this machine to cut off the power in time. Over the years, paper pallets and non whole wood composite pallets have been gradually used). The United States invented the structure of combined heavy-duty cartons as early as the 1950s and patented the use of octagonal clip pads and large square head self tightening screws to fix the bottom of the box and the seat (tray) (. In the early and mid-1980s, patents were introduced into Japan to form a special Naiguan packing box, which can pack heavy goods, castings, mechanical and electrical products with extra long and extra flat width. For overweight large substitute wood packaging, the composite or combined structure of super strong multi-layer corrugated board is used. For example, Rexam company of the United States uses two three tile seven layer corrugated cardboard to stick together to make and form a 14 layer overweight corrugated cardboard box, which can withstand large Ford Trucks. The bearing capacity is more than 7.5t

honeycomb paperboard

honeycomb paperboard is used as a liner and separator in heavy packing boxes. Cooperating with the inner wall of the box, it is a wall panel material for load-bearing reinforcement, which is of great use in the production of all paper pallets. In foreign countries, it is rare for honeycomb paperboard to be made into packaging cartons. For all that. The speed, performance and product quality of foreign honeycomb paperboard production lines are still higher than those of domestic equipment, so the price is very high

substitute wood pallets

substitute wood pallets include honeycomb cardboard pallets, pulp molding pallets, paper filled pallets, plastic pallets, metal pallets, etc. They, together with the packing cases, as a whole of transportation packaging, participate in the high-quality circulation process, which has a history of development for many years abroad. Saving resources and protecting the environment is a common thing, so there are various pallet production lines for the market to choose, so the pallet quality and price are appropriate. We must develop the production technology and equipment of various pallets. As a substitute for wood packaging, it is one of the main contents of innovative technology and product development

bamboo plywood packaging

bamboo plywood packaging mainly replaces large wooden packaging boxes. It has been applied in recent years. The application of bamboo plywood as the wallboard of large and heavy equipment packing cases has achieved good results, and the application of bamboo plywood as the packing plate for load-bearing of large and heavy equipment packing cases is still in further development and experiment. 2、 Flexible packaging paper materials have broad development potential in China's flexible packaging market

dairy market

according to the world development trend. In the future, dairy products should be changed from milk powder to liquid milk, which can save energy, improve nutritional value and facilitate use. It is estimated that by the end of the tenth five year plan, about 6.75 billion aseptic fresh-keeping flexible packaging boxes will be used every year

fruit juice beverage and other beverage industries

according to the China Beverage Industry Association, China's per capita beverage consumption is only one fifth of the world average. There is great potential for product development, and many products need to be developed and developed. Therefore, the demand for flexible packaging cartons will increase greatly

vegetable juice processing industry

at present, the processing of vegetable juice in China is almost blank. With the progress of society. The development of science and technology. With the pursuit of health and the renewal of consumption concept, the production of beverages or condiments from vegetable juice in China will be greatly developed in the next years. The best packaging for this kind of products will be sterile flexible packaging cartons

III. advanced paper packaging technology

waste paper packaging bottle

Kao company of Japan uses waste paper as raw material to make packaging bottles that can contain bleach, shampoo, etc. The recycled waste paper is made into pulp, and then the packaging bottle and bottle cap are made by the molding method of plastic products. It is not only beautiful and practical, but also recyclable and biodegradable after being discarded. Therefore, it is conducive to environmental protection

in the process of making packaging bottles with waste paper, first immerse the waste paper in water, and then beat it into pulp with a beater. The pulp is injected into a metal mold for molding, and then dried into various packaging bottles. This kind of packaging bottle can be used to contain liquid and powdered solid, but when it is used to contain liquid shampoo, etc. The packaging bottle needs to be waterproof by coating a thin plastic coating on the surface, and the scrap price rebounds in some areas

because this method of making packaging bottles with waste paper can be produced in large quantities, its cost is cheaper than the commonly used plastic packaging bottles

oil proof and waterproof agent for paper products comes out

an oil proof and waterproof agent for paper tableware and special paper products has been successfully developed in Tianjin. This product can completely replace imported products. After it was put on the market, users responded well

this oil proof and waterproof agent is mainly polymerized with butoxy hydroxymethyl acrylamide, methacrylic acid, dehydrated glyceride, ethylene glycol dimethacrylate and comonomers. All indicators meet the relevant national standards, and have the dual effects of oil and water resistance, which can make the paper products bright and smooth. This product can be widely used in paper tableware, food packaging paper, moisture-proof paper, glazing paper and other production fields, and provides a new auxiliary product with high quality and low price for the upgrading of domestic paper products
