The unique performance of boiling PVDC coated BOPA film mainly comes from the perfect combination of its double-layer structure. As a substrate, BOPA film provides high strength and excellent barrier properties. The hydrogen bonding between nylon molecular chains makes BOPA film have excellent barrier effect on gases such as oxygen, nitrogen, and carbon dioxide, thereby effectively extending the shelf life of food.
The PVDC coating further enhances the film's high temperature resistance and preservation ability. PVDC is a high barrier resin with excellent oxygen, moisture and gas barrier properties. When it is coated on BOPA film, it can form a dense protective layer that effectively prevents the external environment from invading the food in the package. PVDC coating can withstand high temperatures up to a certain temperature (such as 140°C) without deformation or damage. This feature enables boiling PVDC coated BOPA film to maintain the integrity and sealing of the package during high-temperature boiling.
The application of boiling PVDC coated BOPA film in the food packaging industry is mainly concentrated in the field of food that requires high temperature treatment. These foods need to withstand high temperature and high pressure during processing, and traditional packaging materials often cannot meet this demand. Boiling PVDC coated BOPA film has become an ideal packaging choice for these foods with its excellent performance combination.
Stewed food is a kind of food that needs to be cooked at high temperature for a long time. Its packaging materials need to be able to withstand high temperature and high pressure environment while maintaining the integrity and sealing of the packaging. Boiling PVDC coated BOPA film just meets this demand. Its high strength and high temperature resistance enable the packaging to maintain structural stability during high temperature stewing, while its excellent barrier properties effectively extend the shelf life of the food.
Canned food is a kind of food that has been sterilized at high temperature. Its packaging materials need to be able to withstand the sterilization environment of high temperature and high pressure while maintaining the sealing and barrier properties of the packaging. Boiling PVDC coated BOPA film is also suitable for this field. Its PVDC coating can effectively prevent the external environment from invading the food in the package, while the high strength of the BOPA film ensures the integrity and stability of the package.
In addition, the boiling PVDC coated BOPA film also has good transparency and glossiness, making the food in the package more tempting and delicious. This feature is particularly important in the food packaging industry because it can attract consumers' attention and improve the market competitiveness of products.
In addition to the food packaging industry, boiled PVDC coated BOPA film is also widely used in the fields of medicine, electronic products, etc. In pharmaceutical packaging, its high strength and barrier properties can protect drugs from the external environment, while its high temperature resistance enables it to maintain the integrity and sealing of the packaging during high-temperature sterilization. In electronic product packaging, boiled PVDC coated BOPA film can also provide good protection to prevent electronic products from being damaged during transportation and storage.
With the continuous improvement of consumers' requirements for food safety and preservation, and the growing demand for high-performance materials in the packaging industry, the market prospects of boiled PVDC coated BOPA film are very broad. Especially in the field of food packaging, its unique combination of properties makes it an ideal choice for foods that require high-temperature processing.
However, boiled PVDC coated BOPA film also faces some challenges. For example, its production cost is relatively high, and advanced production technology and equipment are required. In addition, with the improvement of environmental awareness, consumers are paying more and more attention to the recyclability and degradability of packaging materials. Therefore, how to reduce production costs and improve environmental performance while maintaining performance advantages will be an important direction for the future development of boiled PVDC coated BOPA film.
Boiled PVDC coated BOPA film has shown a wide range of application prospects in the food packaging industry with its unique performance combination. Especially in the field of food that requires high temperature treatment, such as stewed food, canned food, etc., it has become an ideal packaging choice. With the continuous advancement of technology and the continuous expansion of the market, boiled PVDC coated BOPA film is expected to play its unique advantages in more fields and bring more efficient, environmentally friendly and safe solutions to the packaging industry.
