Aluminium Foil Roll 1235 O For Flexible Packaging
Aluminum foil is an excellent packaging material. The shortcomings can only be related to its characteristics: light, thin, and soft, and cannot be used for structural packaging. It has limited tensile and shear resistance and must be combined with other materials to ensure packaging. Its strength and ease of use.
When packaging, composite packaging can be used to vacuum; companies and products with high requirements for food packaging basically use aluminum foil packaging.
If you insist on the shortcomings, that is, the aluminum foil used for packaging must be compounded with other materials to achieve good results. Aluminum foil is generally used as a composite material for packaging. Composite materials are difficult to recycle.

The "composite" in the industry actually means "laminate", which means that films of different properties are glued together in a certain way, and then sealed to protect the contents. The composite processing methods of flexible packaging mainly include dry compounding, wet compounding, extrusion compounding, co-extrusion compounding and so on.
Dry compounding is suitable for the compounding of various composite film substrates and films, aluminum foil and paper. It has a wide range of applications and excellent resistance to chemical media. For example, foods and cosmetics contain ingredients such as alkali, acid, spicy, and oil. There are water, flavor, emulsifier and other ingredients. Chemicals include solvents, pesticides and other ingredients. They are widely used in packaging with demanding contents. The composite strength is high, the stability is good, and the product transparency is high. It can produce high- and mid-range composite films. , Can also produce composite films for freezing, preservation or high temperature sterilization; convenient and flexible to use, simple to operate, suitable for small batch production of multiple varieties.
Aluminium Foil Jumbo Roll 30 Micron for Hookah Shisha Because the shape of the aluminum foil for flexible packaging is seriously bad, the aluminum foil will form wrinkles when rolled or unfolded
