Over printed foil: excellent barrier properties and strict production process

In today's society, as consumers have increasingly higher requirements for food safety and quality, the selection of packaging materials has become particularly important. Among them, as a high-tech, high-performance packaging material, top-printing foil is showing extraordinary potential in many fields such as food, medicine, and daily chemical products with its unique advantages. The key reason why over printed foil is so popular lies in its excellent barrier properties against water, air (especially oxygen), light and microorganisms. These properties together build an indestructible protective barrier for the packaged items. Comprehensive protection.

Barrier performance: the first line of defense to protect quality
Barrier to water and oxygen: Water is one of the important factors causing food spoilage, while oxygen is a necessary condition for most oxidation reactions. Both will accelerate the deterioration process of food. The upper printing foil achieves effective isolation of water molecules and oxygen through precise manufacturing processes, greatly reducing the humidity and oxygen content of the internal environment of the packaging, thereby significantly delaying the rate of food spoilage and maintaining the freshness and purity of the product. Taste.

Blocking of light: For some light-sensitive products, such as certain drugs, cosmetics and some foods, exposure to light can trigger chemical reactions, leading to color changes, loss of nutrients and even deterioration. With its excellent light-shielding properties, the upper printing foil effectively blocks the penetration of ultraviolet and visible light, providing a light-proof protective space for these products and ensuring the stability of their quality.

Barrier to microorganisms: Microbial contamination is a major threat to food safety. The high-density structure and special coating design of the printed foil effectively prevent the invasion and reproduction of microorganisms such as bacteria and mold, creating a sterile or low-bacteria environment for food, which greatly reduces the risk of food deterioration due to microbial contamination. .

High temperature annealing and disinfection: safe and hygienic production guarantee
In addition to its excellent barrier properties, the production process of the over printed foil also follows strict safety and hygiene standards. Among them, the high-temperature annealing and disinfection process is a key step to ensure the safety of aluminum foil. This process uses a high-temperature environment to completely kill any bacteria, viruses and microorganisms that may be attached to the aluminum foil during the production process, ensuring that the product reaches extremely high hygiene standards when it leaves the factory. This is not only responsible for the health of consumers, but also a strong safeguard for the corporate brand image.

With its excellent barrier properties and strict production processes, over printed foil plays an irreplaceable role in ensuring the quality of packaged goods, extending shelf life, and reducing waste. With the advancement of science and technology and the diversification of consumer demands, we have reason to believe that high-performance packaging materials such as printed foil will be more widely used in the future, contributing more to food safety, environmental protection and sustainable development.
