Foods requiring the most demanding barrier properties: for example, high-quality milk powders, coffee grounds, and nuts and fried foods with high oil content. These materials are extremely sensitive to oxygen and moisture; Even the slightest intrusion can cause clumping, loss of flavor or oil curdling (a musty smell). 9 Micron Aluminium Foil provides a double insurance policy, maximizing the life of peak flavor and ensuring top quality.
Chemically active everyday chemicals: Many high-end cosmetics, skin care products, and some condiments (such as sauces and hot pot bases) contain a wealth of active ingredients or volatile substances. Not only are these products sensitive to oxygen, but their inherent oily, acidic or aromatic properties can also corrode thin packaging materials. The 9 Micron Aluminium Foil provides a thick metal barrier, effectively preventing component damage, degradation, aroma escape, and the introduction of external odors.
You might think that the Alu Foil Jumbo Roll 1235 For Lamination 9mic aluminum foil is just a thicker version of the 7mic with better performance. But the reality is much more interesting than that. A world of deep customization.9mic aluminum foil is like that. It's a great "basic platform" on its own, but its true power lies in its ability to be a "special forces soldier" with a variety of functions in conjunction with its various products.
Dealing with high temperatures? A piece of cake. For example, some food wrappers and prepared foods need to be boiled or steamed in boiling water. In this case, adding a "lining" made of high temperature resistant plastic (such as CPP) will help it withstand the heat. The bag won’t break or delaminate, and the aluminum foil won’t react with food, making it safe and convenient.
Worried about a puncture? Wear a "stab-proof vest" for this. If you’re packaging meat products or hard-edged snacks with bones, you can coat it with a layer of ultra-tough nylon. This is similar to adding a layer of chain mail to armor, significantly increasing puncture resistance and ensuring safe transport.
Exceptionally smooth and flat plastics (such as PET) such as the outer layer can be used to print beautiful, vibrant designs. When displayed on the shelf, it instantly catches your eye.

Why a thickness of 9 Micron Aluminium Foil was chosen instead of 8 or 10 microns
Customers choose the 9 Micron Aluminium Foil not only for its durability, but also for its reliable foundation, which is flexible enough to meet a variety of needs. This tailor made method is its true best.
You might be curious as to why a thickness of 9 Micron Aluminium Foil was chosen instead of 8 or 10 microns. This was not a random decision; There is a lot of depth involved, a sweet spot that was carefully considered by the engineers.
Think of aluminum foil as tightrope walking. If it’s too thin Alu Foil Jumbo Roll 1235 Alloy(like 7 microns), even if it’s lightweight and flexible, it swings violently in the wind, has a low tolerance for error, and has extremely high demands on manufacturing equipment and processes, even the slightest flaw can cause problems. If it is too thick Alu Foil Jumbo Roll 1235 Alloy (e.g. 12 microns or more), while it is stable, it adds weight and cost, loses flexibility, and becomes bulky, making it unsuitable for many applications that require flexible packaging.
The 9-micron thickness seems to strike the perfect balance. It is more stable than Alu Foil Jumbo Roll 1235 For Lamination 7 microns thick, making it more reliable on production lines and less prone to breakage or creating unsightly micro-holes due to slight vibrations from machinery. At the same time, it is not so thick that it is cost prohibitive or the packaging is too rigid. It ensures top-notch safety while maintaining excellent flexibility and relatively economical cost. So this "9" is a proven golden number in practice. It means "spending your money wisely, while ensuring absolute safety." For many high-value or perishable products, choosing a 9mic offers a more reliable guarantee. The additional cost reduces quality risk significantly, making the trade-off better worth it.
How 9mic Aluminum Foil Locks in Freshness
When we talk about the protective properties of 9mic aluminum foil, many people think it just means "keeping the bad stuff out." While this is true, it also has an equally important ability: "keeping the good stuff from the inside out."
It's like a two-faced guard, guarding a castle. The gates are tightly sealed, preventing the enemy from entering (oxygen, moisture, bacteria), while also preventing the princess within (fragrance, flavor) from escaping. Think of your favorite spicy beef jerky or aromatic coffee: their appealing aroma is actually a collection of volatile molecules. If the packaging is not tight, these aroma molecules will disappear quickly, leaving the food bland and tasteless.
The thick metal layer of 9mic aluminum foil creates an impenetrable barrier, locking these flavor compounds securely inside the package. This ensures you can enjoy the original, full flavor of the product from the moment you open the package to the last bite. It also effectively prevents moisture loss for products that require a certain moisture level (such as some pastries that tend to dry out).
Thus, it is more than just a "protective shield"; It's also a "freshness box." It provides an expansive, stable microenvironment, insulating the contents from the outside world and keeping it safe and secure until you open. Every extra penny you spend buys not only a longer shelf life, but also a compromise-free, perfect experience from the moment you open the bag.
