Tin printing and drying technology after the tin is formed, some words and patterns need to be offset printed to increase the of the product. However, we may not know the drying process. Let's introduce the iron can printing drying technology.
With a certain amount of stock, this non-woven packaging bag has become the choice of many people.
.Classified by appearance: vest bag, straight bag. Sealing bag, rubber strip bag, etc.
Japanese tradition and European melting furnace: Western composition, arrangement, combination space, Japanese modification and material.
.After the iron can enters the oven, the next stage is heating up. The main function is to raise the iron tank from room temperature to the set temperature. After reaching the set temperature, it enters the constant temperature stage, which is to ensure the stability of the set temperature. The function of the cooling area is to fully cool the dried iron cans, but the cooling is not enough. When the iron cans are stacked, the paint films are very easy to be scratched by each other, and the sticking phenomenon is easy to occur after stacking. The baking time has a great relationship with the machine speed. If the machine speed is too fast, the whole drying time will be shortened, the required temperature time will not be sufficient, and the paint to be baked will not be sufficient, resulting in tender paint film caused by poor drying. It makes the food or beverage easy to deteriorate.
() foreign trade export cartons and 5-layer corrugated boxes are generally used for color printing of external non-woven packaging, and B / C tiles are mainly used for corrugated. The calculation formula of outer box is: (length + width + / 100 x (width + height + / 100 x unit price per square meter).
Textile fabrics and biodegradable / photodegradable non-woven fabrics, etc. The varieties developed in China have covered photodegradation, photobiodegradation, photooxidative biodegradation, high starch content biodegradation, high calcium carbonate filled photooxidative degradation, total biodegradation and other categories; Application of degradable non-woven products in non-woven packaging color printing, professional non-woven bags, cotton bags, canvas bags, thermal insulation bags, hand decoration Bags & nbsp; Safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted. They have been widely used in ordinary non-woven packaging color printing films, shopping bags, bags, etc., and have played a positive role in improving environmental quality. In order to protect the ecological balance, it is urgent to study fully biodegradable non-woven fabrics, especially the high-quality and low-cost fully biodegradable non-woven fabrics filled with edible powder or inorganic minerals.
The non-woven packaging bags usually used in the industrial field are bags with thick raw materials. Because industrial goods are usually divided into large and heavy parts, sometimes some goods have severe wear on the bag, so it is necessary to use such bags for packaging. At present, aluminum foil bags are widely used in industry. Due to the particularity of their raw materials, they can fully fit the characteristics of commodities. It can achieve certain maintenance and beautiful results, and it can also be in the market
The gram weight of non-woven fabric of general bag is 80g, 90g, 100g and 120g.
Reach consumers safely. This requires designers to pay attention to the modeling, structure, materials and other aspects of packaging, so as to improve the comprehensive protection of products. For example, in the design of egg packaging, in order to consider the safety, mutual tray design is adopted: the puffed food is filled with nitrogen to keep the crispness of the product itself, At the same time, the survival of products can not be guaranteed, and other functions of packaging lose their significance.
Sincere service.All kinds of commodities, from factories to terminal stores to consumers go through countless links such as transportation and storage. This process is the circulation of Shangjing. In the whole process, from the beginning of convenient packing to easy stacking. To be easy to place in the store and reasonable space: to be convenient for consumers to splice, open and use; Later, it is convenient for waste recycling. Whether it is production, transportation or consumption, people should feel the convenience brought by packaging. Designers should consider the packaging materials, structure and modeling according to various factors in the process of commodity circulation and use, and strive to scientifically realize the convenience of the whole process from production to use to recycling.
Try to use the same material for color printing of non-woven packaging
However, the retention environment of pulp, small plate and red ball in the liquid is different. In the liquid the service life of the small board is short. It can only be retained for 72 hours at the room temperature of 20 ~ 240C. The red ball can be retained for 2L days in the cold storage of 4 ~ 60C. You can choose products and tens of millions of products, professional non-woven bags, cotton bags, canvas bags, thermal insulation bags and hand decoration Bags & nbsp; The transaction is safe and guaranteed. The pulp is well preserved in the cold storage environment of 200C. If they can be classified and retained it is ideal. New non-woven packaging color printing is adopted, sub bags are connected outside the bag, and separation equipment is used to separate pulp, small plate and red ball according to different relative density and sub pack them into different sub bags. Because of the universality of this new technology, it can be realized in the mining process & amp; amp; quot; & amp; amp; quot;, For example in the process of collecting, only small plates are collected, and other components are returned to the donor's. With this method, the number of small plates that can be normally collected at one time by individual donors is equivalent to the number of small plates collected in the previous 10 ~ 20 human fluids.
In the drying process, and the time is about 13 minutes. The coating drying strip is between 170 ℃ and 210 ℃, and the tunnel oven is about 25-35m long. It consists of three stages: heating zone constant temperature zone and cooling zone. These areas are arranged in strict accordance with the requirements. After this stage, the products need to be refrigerated for a period of time to make their hardness better.
Respect for customers.Pragmatic in Europe and America: rationally highlight information (Coca Cola) and make various prompts and explanations with rigorous standardization.
Hot pressing bag: from the literal meaning, it means to press the non-woven fabric into the same non-woven bag at high temperature.
Material elements material elements include basic materials (paper materials, non-woven materials, glass materials, metal materials, ceramic materials, bamboo and wood materials, leather materials and other composite materials) and auxiliary materials (adhesives, coatings, etc.), which are the material basis for the realization of the great functions (protection, convenience and) of non-woven packaging color printing, It is directly related to the overall function and economic cost of non-woven packaging color printing, production and processing mode, and the recycling and treatment of non-woven packaging color printing waste.
.Reach consumers safely. This requires designers to pay attention to the modeling, structure, materials and other aspects of packaging, so as to improve the comprehensive protection of products. For example, in the design of egg packaging, in order to consider the safety, mutual tray design is adopted: the puffed food is filled with nitrogen to keep the crispness of the product itself, At the same time, it also ensures that the products will not be broken: the colors of beer bottles are mostly dark green and dark coffee. It has long been considered that the bottle body is isolated from the sun under the light. The protection function mainly refers to the function that acts on objects rather than people. This is the basic function of packaging. Without the protection function, the survival of products can not be guaranteed, and other functions of packaging lose their significance.
Vacuum non-woven packaging bag the food packed in vacuum packaging bag sometimes adds some agents or other chemicals that change the taste of food in order to increase the shelf life, because it needs to be heated when sealing and vacuumizing, it can save non-woven packaging color printing materials, reduce the cost of non-woven packaging color printing and reduce the pressure of environmental protection. When considering the shape elements of non-woven packaging color printing design, we should give priority to those geometries that save raw materials. Among various geometric bodies, if the volume is the same, the surface area of the spherical body is small; For prism, the surface area of cube is smaller than that of cuboid; For a cylinder, when the height of the cylinder is equal to the diameter of the bottom circle, its surface area is small.
