Aluminum Foil For Food Packing Per Ton
With the increasing enrichment of life, the types of food are also constantly enriched...Different types of food have different packaging.
Food packaging bags can help food extend the shelf life, but the shelf life of different materials is different.
Aluminum foil bags are very common in food packaging, and their use must meet certain sealing requirements, and the sealing degree of aluminum foil bags must also be ensured.
The common and strict sealing method is the heat sealing method
The heat sealing method is a method of fusing two layers of aluminum foil together. This fusion method enables the two layers of aluminum foil to be combined into one without cracking or breaking, and at the same time, there will be no leakage problems, so as to meet the sealing requirements. Food packaging bags are manufacturing process requirements formulated by functional requirements, so that the packaging can achieve a certain use effect.
There are many specifications of aluminum foil packaging bags, not only different in size, but also different in thickness, which also makes it meet the standards of packaging requirements.
The thickness and other specifications of the aluminum foil material of the packaging bag used in different product packaging are different, which is determined by the nature of the aluminum foil packaging of the product. For products with strict vacuum requirements, the thickness of the material used should be larger.
The greater the thickness of the aluminum foil packaging bag, the tighter the packaging and sealing performance, the more it can meet the packaging requirements, but the cost of aluminum foil packaging materials will be higher. The cost of aluminum foil packaging materials is calculated by quality.
Food packaging bags are not made of simple aluminum foil, but made of composite materials. This composite material is made of aluminum foil and nylon. Some are made of four-layer co-extruded film. As far as food is concerned, it is often a multilayer composite material.
The reason for using aluminum foil multilayer composite materials is to package food, and more importantly, to maintain food quality requirements. The other is that rich colors and patterns can be printed on food packaging bags. This is why the current food can be recognized by the market in a way, and the importance of appearance is also a necessary way of publicity for food.
