First, the selection of raw materials for aluminum-plastic composite film
1. Plastic film, such as polyethylene (PE), polyester (PET), etc.
2. Aluminum foil, usually made of high purity and bright surface;
3. Adhesives, commonly used polyurethane adhesives, acrylic adhesives, etc.
Second, the production process of aluminum-plastic composite film
1. Plastic film molding: make the required plastic film to the required thickness and width;
2. Adhesive coating: the adhesive is evenly coated on the surface of the plastic film;
3. Place the aluminum foil: Cover the aluminum foil on the plastic film to ensure that the surface of the aluminum foil is in full contact with the adhesive;
4. Pressing: by pressing the aluminum foil and plastic film composite;
5. Roller coating printing: printing the composite aluminum-plastic film, printing color, pattern, text, etc. can be customized according to customer needs;
6. Finished product production: cutting, edge sealing and other customized processing according to customer needs.
Third, matters needing attention in the production of aluminum-plastic composite film
1. Pressing temperature, time, pressure and other process parameters need to be determined according to the specific composite material;
2. When preparing adhesives, it is necessary to pay attention to the proportion of components to ensure that the adhesive is evenly coated and has good adhesion;
3. In the rolling coating printing process, the printing thickness needs to be controlled to ensure the printing quality;
4. When making finished products, it is necessary to do a good job of cutting, edge sealing and other processing procedures to ensure the appearance and quality of finished products.
The above is a detailed introduction to the production process of aluminum-plastic composite film, and I hope to provide you with some help. It should be noted that in the production process, we must pay attention to environmental protection and safety issues, and actively take measures to reduce the production of waste gas, waste water, etc., to ensure the safety and stability of the production process.
