PVDC Coated Films' excellent chemical resistance and aroma retention performance lead packaging innovation

The excellent performance of PVDC coated film is first reflected in its chemical resistance. Many foods and daily consumer products are often exposed to external factors such as oxygen, moisture and oil during the packaging process, resulting in a decrease in their quality and taste. PVDC coated film can effectively prevent the penetration of oxygen, thereby delaying the oxidation and corruption of food and maintaining the flavor and freshness of food. Especially for products with high fat, high sugar or high humidity, the barrier performance of PVDC film is more significant. It can effectively isolate harmful substances in the external environment and ensure that the product is not contaminated or deteriorated during long-term storage, thereby greatly extending the shelf life of the product.

In addition to antioxidant properties, PVDC film also performs well in aroma retention. For many foods, especially coffee, spices, baked products, etc., the aroma is the most important part of the consumer experience. Traditional packaging materials often find it difficult to effectively prevent the loss of aroma, resulting in the loss of the original aroma and freshness of the product during storage or transportation. PVDC coating film has gas barrier ability and can effectively maintain the aroma of food, so that coffee beans, spices and other flavored products can retain their natural aroma to the maximum extent during the packaging process. Therefore, PVDC coating film has become an ideal choice for high-end food packaging, especially for goods that need to be stored for a long time or transported across borders.

In addition, PVDC coating film also has oil resistance. When dealing with foods with high oil content, such as potato chips, nuts, fast food, etc., PVDC film can effectively prevent oil penetration and avoid greasy substances from eroding packaging materials, thereby extending the storage period of food and maintaining the appearance and quality of the product. This feature makes it widely used in the packaging of high-fat foods, helping to maintain the freshness and flavor of food while improving the durability of packaging.

PVDC coating film also has good processing performance and can be well compounded with other materials to form a high-performance multi-layer structure. Whether it is heat sealing performance, printing performance or lamination process, PVDC coating film can be perfectly combined with other packaging materials such as PET, BOPP, etc. to provide multi-level protection functions. Its heat sealing property makes the packaging process more efficient, especially in the high-speed operation of the food packaging line, PVDC film can achieve stable heat sealing strength to ensure the integrity and sealing effect of the packaging. This is undoubtedly an ideal choice for food packaging manufacturers who need efficient production.

In terms of environmental protection, with the increasing global demand for sustainable packaging materials, PVDC coated film has also begun to gradually move towards a more environmentally friendly direction. Although the recycling of PVDC film is still the focus of industry attention, many research institutions and companies are exploring ways to improve its production process and recycling methods, striving to ensure packaging performance while improving its sustainability and environmental protection. In the future, with the advancement of technology, PVDC coated film is expected to achieve higher recycling efficiency and further reduce the negative impact on the environment.

PVDC coated film has become an indispensable key material in food and high-end consumer product packaging due to its chemical resistance, aroma retention performance and high barrier properties. Whether it is to extend the shelf life of food, maintain its freshness and flavor, or protect products from external environmental factors, PVDC film can provide an ideal solution. As consumers' requirements for food quality and packaging performance continue to increase, PVDC coated films will continue to play an important role in the packaging industry and promote packaging technology to develop in a more efficient, environmentally friendly and sustainable direction.
