In the four pillars of modern packaging - paper, plastic, metal, glass materials. One of the fastest growing paper products. Paper and plastic are the cheapest. Raw materials are widely sourced and not as fragile as glass, nor as heavy as metal. Easy to carry.
The International Health Organization and domestic environmental protection experts believe that domestic and foreign markets will gradually ban the use of plastic food bags. In the future, shopping should use non-toxic and harmless “full-paper eco-bags”. Paper products are prone to decay and can either recycle recycled paper or make plant fertilizers. It can also reduce environmental pollution. Purifying air.
First, the main packaging paper and paperboard wood packaging materials
Foreign wood packaging
Heavy wood packaging in developed countries, including the use of high-strength multi-story (double arch) corrugated carton (box body); non-wood pallets (seat table): edge, corner, bottom, roof reinforcement of structural materials and septum The use of non-wood products such as liners, padding, filling buffers, positioning, protection, and accessories (combination and filling) has been in the commercialization stage as early as the mid-1980s. However, until now, a certain amount of boxes made of processed wood products such as fumigated wooden boxes and plywood have been used. Its technology and equipment have a high level.
Common wood packaging paper
High-strength multi-layer corrugated cardboard boxes for heavy-duty packaging
For small and medium sized wood cartons, three corrugated paperboards (usually seven layers) are generally used to make heavy-duty crates through automatic production lines, which are fixedly connected to the wooden pallets at the bottom of the box. (In recent years, paper pallets and non-whole wood have been gradually used. Combination tray). As early as the 1950s, the United States invented the structure of a combined heavy-duty carton and used a octagonal clamp pad and a large-head self-tightening screw to fix the bottom and seat (tray) patents (uspat.No. 2469710, etc.). In the early and mid-80s of the 20th century, patents were introduced into Japan to form a special-resistant crown packing box, which can pack heavy goods, special flat-width heavy items, castings, and electromechanical products. For super-major type wood packaging, the composite or composite structure of super-multilayer corrugated cardboard is used. For example, the American company Rexam uses two three-watt seven-layer corrugated paperboards to glue together, making and constructing a 14-story, overweight corrugated cardboard box that can withstand large Ford trucks. Load 7.5t or more.
Honeycomb cardboard
Honeycomb cardboard is used as a liner or spacer in heavy-duty containers. Cooperate with the inner wall of the box to reinforce the wall material for load-bearing, and use it in the production of full-paper trays. In foreign countries, it is rare to make cardboard cartons. despite this. The speed, performance and product quality of foreign honeycomb paperboard production lines are still higher than that of domestic equipment, and thus the selling price is very high.
Wood pallets
On behalf of the wood trays are honeycomb cardboard trays, pulp molded trays, trays filled with fillers, plastic trays, metal trays, etc. Together with the packaging box, they are used as a whole for transport packaging and participate in high-quality circulation processes, which have been developed abroad for many years. Saving resources and protecting the environment are commonplace. Therefore, there are various pallet production lines available for market selection, so the quality and price of pallets are suitable. We must develop various pallet production technologies and equipment. As a “generation wood packaging” is one of the main contents of innovative technology and product development.
Bamboo plastic sheet packaging
Bamboo plywood packaging mainly replaces large wooden crates. In recent years has begun to apply. The application of the bamboo glue board for the heavy-duty equipment box wall board has achieved good results, and the application of the heavy-weight equipment box load-bearing packing board is still in the further development experiment. Second, flexible packaging materials in China's flexible packaging market has a very broad development potential
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 and improve nutritive value and ease of use. It is expected that at the end of the “10th Five-Year Plan”, about 6.75 billion soft packaging boxes will be used each year.
Juice drinks and other beverages
According to the China Beverage Industry Association, China's average per capita beverage consumption is only one-fifth of the world average, and the potential for product development is huge. Many products are still to be developed and developed. Therefore, the demand for flexible packaging cartons will greatly increase.
Vegetable juice processing industry
At present, the processing of vegetable juice in our country is almost blank. with the development of the society. The development of technology. People's pursuit of health and renewal of consumer attitudes, in the next 5-10 years, China's vegetable juice production of beverages or condiments will be a greater development, the best packaging of such products will be aseptic soft packaging carton.
Third, advanced technology of paper packaging technology
Bottles with waste paper bottles
Kao Corporation uses waste paper as raw material to make bottles that can hold bleach and shampoo. The recovered waste paper is made into pulp, and then the plastic bottles are used to form the bottles and caps, which are not only beautiful and practical, but also can be recycled. After being discarded, they can also be biodegraded. Therefore, it is conducive to environmental protection.
In the process of manufacturing packaging bottles from waste paper, the waste paper is first soaked in water, and then beaten into pulp by a beater. The pulp is formed by injecting into a metal mold and dried to form various bottles. This bottle can be used to contain liquids, powdered solids, but contains liquid shampoos, etc. The bottle needs to be waterproofed by applying a thin layer of plastic coating on the surface.
Since such a method using waste paper bottles can be mass-produced, its cost is lower than that of commonly used plastic bottles.
Anti-oil waterproof agent for paper products comes out
An oil and water repellent agent for paper tableware and specialty paper products was successfully developed in Tianjin. This product can completely replace imported products. After the launch of the market, users responded well.
This oil and water repellent agent is mainly formed by polymerization of butoxymethylol methacrylamide, methacrylic acid, dehydroglycerol ester, ethylene glycol dimethacrylate and comonomer. All indicators are in line with the relevant national standards, with oil-and water-repellent dual-performance, can make paper products show bright and smooth. The product can be widely used in paper tableware, food packaging paper, moisture-proof paper, glazing paper and other production areas, for the upgrading of domestic paper products to provide a high quality and low price of new additives products.
