Product Differentiation & Market Advantages
Most cold-form aluminum foils on the market are universal flexible materials, while our Hard Cold Form Alu Rolls For Capsule Blister Pack is a customized hard-type product for capsule packaging scenarios, with targeted structural optimization. Aiming at the problem that capsule blisters are easy to be squeezed and deformed during commodity circulation, we increase the overall structural rigidity of the aluminum foil, ensuring that the three-dimensional blister cavity remains intact after long-distance transportation and stacking, protecting capsules from extrusion damage.
In terms of barrier technology, this product adopts double-layer compact composite structure, which solves the common defects of single-layer cold-form foil such as easy air permeation and poor moisture resistance. It is more suitable for long-term storage of capsules in high-temperature and high-humidity regions such as Southeast Asia, Middle East and South America, helping customers' products adapt to diversified global market environments and reduce after-sales quality complaints.
