According to reports, the research project was approved by the Provincial Science and Technology Department in 1999. It was jointly funded by South China University of Technology and City Huilong Plastic Machinery Co., Ltd. under the auspices of Guangdong Province and the National Natural Science Foundation and the Science and Technology Project. It is a composite independent innovation achievement of computer technology modeling and simulation, rheology, mechanical equipment, control, polymer materials and other technologies and disciplines.
The extruder developed by the research results is called "chaotic mixing type low energy extruder". On-site inspection by the Guangdong Provincial Technical Supervision Machinery Product Quality Inspection Station showed that the extruder achieved a major breakthrough in energy consumption. Previously, China's polymer packaging material extrusion compound production line has long been monopolized by foreign companies, mainly imported from Japan Sumitomo, Modern and Musashino, South Korea Xing'an and other companies. This achievement has achieved independent intellectual property rights, filled the domestic gap, broke the long-term monopoly of foreign products in the Chinese market, and produced good economic and social benefits. The results are of great significance for the development of China's packaging industry and the promotion of packaging technology and the enhancement of product competitiveness in China's food, beverage, dairy, cosmetics, pharmaceutical, industrial and agricultural chemical industries.
EVA shrink films are designed for products that require high shrinkage but medium barrier properties,such as frozen meat.Made of EVA/PE material,it has the characteristics of high water vapor barrier,excellent transparency and gloss,high puncture resistance and so on.We can custom any sizes you need for large quantity,and also offer standard sizes for most customers.
Here are the standard widths:
165mm,180mm,190mm,205mm,225mm,250mm,275mm,300mm,325mm,350mm,375mm,400mm,425mm,450mm,475mm,500mm,and the length can be any size.
We also provide printing service with flex Packaging Machine,the machine can print 20 colors at most. Below are packaging operations:
1. Set appropriate temperature on the vacuum machine and hot water tunnel;
2. Place opening of EVA Shrink Film over the sealing bar. Make sure the product is not too hot (with vapor) and with minimal contamination to ensure longer shelf life. Examine that there are no wrinkles over the sealing area to avoid breakage;
3. Make sure the product has not been pressed at the bottom of the EVA Shrink film, and the area of the seal is completely clean;
4. Leave about 5cm space between product and vacuum seal. This is to improve vacuum effect, and also to allow some room for product to expand after freezing (for frozen product);
5. Place vacuum packed product in water for 1-2 seconds.
Barrier shrink EVA Shrink film is a flexible packaging solution made of plastic shrink EVA Shrink film,which shrinks around the product after heating,just like the second layer of skin of the product.The barrier shrink EVA Shrink film protects the product throughout the distribution process.If the packaging EVA Shrink film is accidentally damaged,it can significantly reduce the impact on the meat and minimize the loss.
These shrink EVA Shrink films have barrier properties to prevent ambient gases, moisture, aroma and other factors.
With excellent sealing performance, excellent puncture resistance, transparency and excellent adhesion, barrier shrink EVA Shrink film has attracted extensive attention among end users.
Shelf life is one of the most critical factors when end users use packaged food.Barrier shrink EVA Shrink films provide manufacturers and retailers with the advantage of extending the shelf life of products.All these EVA Shrink films also show a better visual appeal to the product,so as to attract customers.These types of EVA Shrink films mainly affect the shelf life of Chicken and birds, poultry, broiler,cheese, quail, etc.,and create sufficient opportunities for the industry to expand its market trail.
In addition,global consumer concerns about convenience,hygiene and food safety are also increasing,which is affecting the entire packaging industry.
