With the development of economy and social progress, packaging has become an indispensable part of people's life. As a new type of packaging material, aluminum foil bag is more and more favored by consumers.
1: aluminum foil bag material
Aluminum foil bag material is mainly aluminum alloy. Aluminum alloy has good corrosion resistance, heat resistance and impact strength, but because of its high density, not easy to shape, so it is not suitable for use as a packaging container. Aluminum foil bags are usually wrapped in plastic or cardboard. Plastic tray has good wear resistance and chemical stability, very suitable for packaging container; Cardboard tray is more durable, and easy to process molding. Aluminum foil bags can be packed in a variety of ways: for example, common cylindrical cartons or square boxes, can also be made into different sizes of rectangular or oval boxes, can also be customized according to user requirements, such as appearance patterns. Aluminum foil bag has strong compressive resistance and ductility, can withstand a certain degree of pressure action, so it is widely used in the field of transportation packaging.
2: Packaging methods and characteristics
There are many kinds of aluminum foil bag packaging methods, each has its own characteristics. Aluminum foil bag materials mainly include aluminum alloy, plastic and paper. The shape of the foil bag can be round, square or rectangular. What is p e pp? There are also many different types of aluminum foil bag sealing, such as zip closure, screw closure, screw closure and so on. Aluminum foil bags come in white, colored and mixed colors. In addition, the aluminum foil bag also has the advantages of good waterproof performance, strong wear resistance, not easy to break. Aluminum foil bags are suitable for most food, beverage, candy, cigarettes and other products.
3: Application domain
Aluminum foil bags are a common packaging material used in the food, beverage and pharmaceutical industries. Because of its good corrosion resistance and wear resistance, it is widely used in the packaging of various products. Aluminum foil bags mainly include cardboard or plastic film and multiple layers of PVC coating and other forms. Cardboard/plastic foil bags are made by layering paper or plastic film with metal or non-metal, and coated with anti-corrosive pigments and antioxidants. This composite film can effectively prevent water from seeping into the printed matter and extend the service life of the printed matter. Multilayer PVC coated aluminum foil bags are usually bonded with three layers of films of different thicknesses, so that they have good chemical corrosion resistance and impact strength, and can withstand alternating hot and cold changes at higher temperatures without damage. In addition, this packaging method can greatly increase the packaging cost and reduce production efficiency.
As a new packaging material, aluminum foil bag has many advantages. Such as light, easy to fold and other characteristics, has a higher competitiveness in the market. At the same time, because it is non-toxic and harmless, there is no harm to the human body, so it is widely used in various occasions.
