Ii. Product Performance: The "Hardcore Strength" of High-barrier Aluminum-coated Paper

The high-barrier aluminized paper of Cailong New Materials, with its unique process and material combination, has become an "all-round player" in the packaging industry. Its core technical highlights include:

1. Excellent barrier performance

High-barrier aluminized paper is a new type of packaging material with excellent performance. It is to coat a layer of aluminium on the surface of the paper. This endows the paper with excellent barrier properties, effectively blocking the passage of oxygen, water vapor and light. Its oxygen transmission rate (OTR) is ≤0.1 and water vapor transmission rate (WVTR) is ≤0.3, thereby protecting the items inside the packaging, extending their shelf life and maintaining quality, and replacing plastic packaging.

The aluminum layer has strong adhesion and high composite strength, avoiding the problem of coating peeling caused by transportation or storage.

2. Environmental protection and recyclability

Biodegradable, recyclable and replaceable plastics are in line with the global trend of the "plastic restriction order". The main components of the product are paper and degradable materials. It supports recycling and has a minimal impact on the environment after degradation.

3. It combines printing and aesthetics

It has excellent light-blocking properties while maintaining metallic luster and printability, meeting the pursuit of high-end brands for packaging visual effects. It can be directly printed to make bags, presenting a bright appearance and enhancing the packaging grade of products.

Iii. Application Scenarios: Demands from fields such as food, medicine, and cosmetics

High-barrier aluminum-coated paper, with its multi-functional characteristics, has become the "packaging favorite" in many industries:

1. Food packaging

For products with high requirements for oxygen and moisture resistance, such as coffee, tea and chocolate, the high-barrier aluminum-coated paper of CAI Long can effectively prevent the passage of oxygen and water vapor, and has high light-blocking properties, which can extend the shelf life by more than 30%.

2. Packaging of alcoholic beverages and cosmetics

High-basis weight aluminized paper is used for wine boxes and cosmetic gift boxes, which not only has excellent anti-counterfeiting effects but also a luxurious texture. It is both beautiful and fresh as well as easy to identify.

3. Pharmaceutical packaging

Aluminized paper has excellent water resistance, oxidation resistance, UV resistance and anti-permeation properties, which can help maintain the stability and effectiveness of drugs and is often used to make medicine packaging boxes, etc.

Iv. Technical Advantages and Product Characteristics of Colored Dragon Aluminized Paper

The aluminum-coated paper of CAI Long adopts an advanced vacuum aluminum-coated process to form a uniform and dense aluminum layer on the surface of the base material. The thickness is controllable and the adhesion is strong, ensuring that the aluminum is not easily removed during the composite processing. Its products combine metallic luster with the flexibility of paper, featuring high gloss and excellent printing performance, which can meet the decorative requirements of high-end packaging. In terms of functionality, the oxygen transmission rate (OTR≤0.1) and water vapor transmission rate (WVTR≤0.3) of aluminum-coated paper stand out, effectively extending the shelf life of contents such as food and medicine. In addition, the colored dragon aluminized paper is environmentally friendly, safe and reliable. It uses paper instead of plastic, reducing the use of plastic and enhancing the feasibility of recycling.

V. Future Outlook

With the development of the packaging industry and people's recognition of environmentally friendly materials, the future development prospects of aluminum-coated paper are broad. With the upgrading of the plastic restriction order and consumption upgrade, the trend of aluminum-coated paper replacing plastic packaging is clear, but it also faces many challenges. Enterprises need to constantly innovate, optimize product structure, enhance technological level, strengthen environmental awareness, and actively respond to market changes in order to achieve sustainable development.
