I. Product Overview: Precision Specifications for Cap-Specific Scenarios

8011 H26 0.150mm anti-theft cap aluminum foil belongs to the national standard 8xxx series Al-Fe-Si specialized aluminum alloy materials.

It is a functional aluminum foil specifically developed for the stamping, threading, and sealing processes of anti-theft caps, distinguishing itself from ordinary decorative, pakiranje, or thermal conductive aluminum foils with its strong deep-processing adaptability and scene specificity.

• Legura 8011:​ A classic and mature grade in the packaging foil field, featuring a scientific ratio of iron and silicon elements and extremely low impurity content. This ensures forming stability and weather resistance at the material source.
• Temper H26:​ A semi-hard work-hardened state achieved through precise cold working hardening combined with low-temperature partial annealing. This process resolves the industry pain point of aluminum materials being “prone to collapse if too soft” ili “prone to cracking if too hard.”
• Thickness 0.150mm:​ A universally validated “golden thickness” for anti-theft caps. It is moderate—not overly heavy—while providing sufficient support for forming.

This specialized aluminum foil features a uniform and dense internal grain structure with strong material stability. It is adaptable to full-process deep-processing techniques such as stamping, duboko izvlačenje, high-speed threading, and hemming. Its standardized core parameters are as follows:

II. Market Demand: Packaging Upgrades Fuel High-End Aluminum Foil Trend

Posljednjih godina, China’s food safety supervision system has continuously improved, and packaging safety standards in the pharmaceutical, hrana, and beverage industries have been upgraded. This drives the anti-theft packaging industry into a phase of rapid upgrading.
