Packaging Aluminum Foil Jumbo Rolls in the Market
Aluminium foil is an important material in laminates and has wide application in food packaging. Its barrier function against the migration of moisture, oxygen and other gases, and volatile aroma, as well as against the impact of light is generally higher than any plastic laminate material.Therefore, aluminium foil is used in the laminates when insufficient barrier properties are the limiting factor for shelf-life stability of food.
The barrier properties of aluminium-coated plastic laminates, which can offer an alternative to aluminium foil laminates, are somewhat less efficient.
The use of aluminium foil in rigid, semirigid, and flexible package for in-pack thermal processing allows the selection of package geometries that ensure rapid heating and minimum heat damage during processing.
On the tightness of packages, the mechanical stability and quality of sealing is of particular importance.
The chemical stability of aluminium foil china in contact with food depends on the composition of the food items. With present toxicological knowledge, the use of aluminium in packaging material is considered to be safe, and inner-coating of the foil is recommended in specific cases.
In developed countries, flexible packaging has become one of the main packaging forms for food and beverages, replacing canned and bottled products within a certain range. In recent years, China's flexible packaging market has also developed rapidly. Aluminum foil composite production lines have been introduced, which can be used in different processes such as dry compounding, hot melt compounding and extrusion compounding depending on the use of flexible packaging. Flexible packaging is not only moisture-proof and fresh-keeping, but also can print a variety of patterns and texts, making it an ideal material for modern commercial packaging.
Aluminum-plastic composite tubes are widely used in the packaging of toothpaste, cosmetics and some industrial products because of the excellent barrier properties, strong corrosion resistance and good printability. In 2002, aluminum-plastic composite pipes have completely replaced the toothpaste packaging of traditional aluminum tubes. In addition, the demand for aluminum-plastic composite hoses in the fields of medicine and health care products, cosmetics, condiments, and industrial supplies has also increased to varying degrees.With the improvement of people's living standards, there is still much development space in flexible packaging aluminum foil roll.
