Soft foil

Soft foil

Aluminum foil has a high sealing, very low air permeability, oxygen permeability. Combined with its own metal radiation, plasticity, widely used in life. It is basically divided into: aluminum paper, aluminum plastic, Tetra Pak (seven layers), heat seal, milk cover and so on. Especially in the fields of medicine, high-end food, cosmetics, cigarette cardboard and so on is a very practical basic material.

Soft aluminum foil processing refers to a process of processing and making aluminum foil in the flexible packaging industry, which is mainly used in food packaging, pharmaceutical packaging, cosmetic packaging and other fields. Soft foil processing is widely used in various packaging fields, because of its good fresh-keeping, moisture-proof, fireproof, heat insulation and other characteristics, by people's favor.

The processing process of soft aluminum foil mainly includes the selection of aluminum foil coil, printing composite, drying, cutting, forming and other links. The first is the selection of aluminum foil coil, according to the requirements of the product to choose different specifications and thickness of aluminum foil coil. Then is the printing composite, through the printing process to print the necessary food identification, logo and other information to the surface of the aluminum foil, while the composite treatment, enhance the wear resistance, water resistance, oxidation resistance and other properties of the aluminum foil. Drying is to achieve a certain degree of dryness of the processed aluminum foil products for subsequent processing operations. Cutting is to cut the aluminum foil material after printing according to the product size, so that it meets the market demand. After the molding, the aluminum foil material will be cut and molded into a variety of food packaging bags, bags of rations, cosmetics packaging boxes and other products.

The advantages of aluminum foil processing are mainly reflected in the following aspects: First, the preservation performance is good, aluminum foil has excellent air tightness and gloss, which can effectively protect the freshness and taste of food and extend the shelf life of food. The second is good moisture resistance, aluminum foil material has good moisture resistance, can avoid food spoilage. Third is strong fire resistance, aluminum foil has good fire performance, help to protect the safety of packaging items. In addition, the aluminum foil also has good thermal insulation performance, which can effectively isolate the external ambient temperature and keep the temperature of the packaged items stable.

The application fields of soft foil processing are very wide, mainly including food packaging, pharmaceutical packaging, cosmetic packaging and other fields. In the field of food packaging, soft foil bags are widely used in packaging all kinds of dried fruits, dried fruits, potato chips, biscuits and other foods, with good air tightness and fresh-keeping effect. In the field of pharmaceutical packaging, soft aluminum foil material bags are used to package various drugs, health products and other products to ensure the safety and efficacy of products. In the field of cosmetic packaging, soft aluminum foil boxes are used to package all kinds of cosmetics to enhance the sense of grade and protection of products.

In general, aluminum foil processing is an important flexible packaging processing technology, with a wide range of application prospects and market demand. With the improvement of people's living standards and the continuous improvement of the safety and quality requirements of food, medicine, cosmetics and other products, the processing of soft foil will usher in a broader space for development. Aluminum foil processing enterprises should increase technology research and development efforts, improve product quality and brand image, meet market demand, and promote industrial upgrading and transformation.
