Green Plastic Packaging Material - PVDC
When we enter the mall supermarket, we will be attracted by a variety of products. Their beautiful packaging is showing you their unique charm. Indeed, good products need good packaging. In people's traditional ideas, the intuitive evaluation of a product mainly depends on the appearance of the product. This shows that the product packaging is very important. Choosing a good packaging material is an important way to reflect the corporate image and demonstrate the quality of the product. PVDC coating is an excellent "green" plastic packaging material.
PVDC (polyvinylidene chloride) is a light yellow, powdery, high barrier material. In addition to the general properties of plastics, it also has self-extinguishing properties, oil resistance, taste protection and excellent moisture, yin and other properties, but also has excellent printing and heat sealing properties. PVDC is a packaging material with the best comprehensive barrier performance in plastic packaging in the world today. It is different from the fact that the polyvinyl alcohol has a sharp drop in gas barrier property as the moisture absorption increases, and it also differs from the nylon membrane in that the moisture-barrier property deteriorates due to the water absorption. It is a high-barrier performance material that is both moisture- and gas-barrier. Below is a set of numbers that can be intuitively reflected. In 224 hours, the temperature is 30.80°C, the relative humidity is 90%, the area per square meter, the oxygen permeability (OTR) of -PVDC is only L.2-26.4ML, and the nylon is 40.3ML of the original ethylene. It is 3875-13020ML. From the comparison of this set of figures, it can be seen that the barrier performance of PVDC is several times, more than ten times that of ordinary packaging materials. Even several hundred times. Therefore, the use of PVDC coating film packaging foods on the food color, aroma, taste, moisture, etc. have excellent protection, can make food preservation period increased several times, dozens of times, hundreds of times, can greatly reduce the food seasons, etc. The variety of factors caused a lot of losses. The proportion of PVDC in the actual packaging is very limited, and the increase in the cost of composite products is very small, so the application of PVDC in packaging is promising.
PVDC not only has excellent high barrier properties, but also has excellent printing performance, composite properties and transparency. In practical applications, PVDC film also has special requirements for printing ink, compounding and equipment. Therefore, it is not necessary to change the process of each process, thereby greatly improving production efficiency and reducing costs.
The application of PVDC is very extensive, involving various industries such as food, chemical, cosmetics, cosmetic products, pharmaceuticals, hardware and machinery products, and military supplies. As early as the fifties and sixties, it was widely used in Western developed countries. China's PVDC started late, so people do not know much about PVDC, and the concept of packaging is relatively weak. Therefore, the application of PVDC is also relatively limited. With the increasing attention paid to environmental protection issues, PVDC composite packaging materials with a relatively light weight have attracted extensive attention. Because of its application, it is possible to achieve a reduction in the extensive use of packaging materials, thereby reducing over-exploitation of waste sources and resources. PVDC is a non-toxic, safe plastic material that has been recognized as a "green" packaging by various countries!
At present, there are many PVDC coating film production lines in China. Among them, Zhejiang (Zhangzhou) Futong Plastic Packing Co., Ltd. is a large domestic manufacturer specializing in the production of PVDC coating film. The company has high-grade coating film production lines imported from Switzerland and high-speed slitting units imported from the United Kingdom. It specializes in producing all kinds of PVDC coating films with an annual production capacity of 2,000 tons. The company has successively formed a variety of products including KOP, KPET, KPA, and K-coated cardboard. In 1999, the company passed the IS0900 certification. The products have been recognized and affirmed by experts and companies at home and abroad. It also hired well-known experts from home and abroad as technical guidance to further develop new packaging materials to meet the higher requirements of packaging.
In summary, the use of PVDV can not only improve China's packaging product quality, but also reduce the losses caused by product packaging, thereby enhancing market competitiveness and establish a new corporate image. I believe that in the future packaging industry, the full and reasonable use of PVDC coating film will become the mainstream of the packaging industry.
