Solventless Laminating Machine Suppliers

A laminating machine is an industrial equipment that laminates two or more substrates (such as film, paper, aluminum foil, and other coils) into one through adhesives or hot pressing processes. It is widely used in packaging, building materials, medical, and new energy fields. It combines materials through dry, wet, and composite processes: dry laminating uses solvent glue to volatilize in an oven and then hot press bonding, which is suitable for high-barrier food packaging; wet laminating uses water-based glue to directly adhere and then dry, and is mostly used for paper and plastic materials. Solvent-free lamination is an environmentally friendly material bonding technology that uses AB glue to directly apply it to the surface of the substrate at room temperature or low temperature, and then composite it with another layer of material. Compared with traditional composite technology, it is more environmentally friendly.

How does Solvent Based Dry Laminating Machine achieve volatile and hot press bonding of solvent-based adhesives?

1. Coating stage: Evenly coat the adhesive mixture

The workflow of Solvent Based Dry Laminating Machine is mainly divided into three key links: coating, drying and hot pressing. First, during the coating stage, the device uniformly coats the adhesive containing organic solvent on the surface of the substrate. These solvents usually have low boiling point characteristics such as ethyl acetate, etc., and their presence can reduce the viscosity of the adhesive, allowing them to spread and wet the substrate better. At this time, the adhesive and the solvent form a mixed liquid, and the substrate such as plastic film, aluminum foil and other materials are covered with a set thickness through the control of a precision metering roller or a gravure roller.

2. Drying link: efficiently realize solvent volatility

Then it enters the drying stage, which is the core step in achieving solvent volatility. The coated substrate is sent to the drying box, and the temperature is accurately controlled between 60℃ and 80℃ through a hot air circulation system. Under the action of high-temperature hot air, the low-boiling organic solvent vaporizes rapidly and discharges the equipment through the exhaust system. It is worth noting that the drying process requires extremely high accuracy of temperature and wind speed control. Too low temperature will lead to solvent residue, affecting the composite strength and safety; too high temperature may damage the substrate and even cause fire risks. Professional Solvent Based Dry Laminating Machine suppliers, such as China's Jiangyin Huitong Packaging Machinery Co., Ltd, will optimize the drying box structure and temperature control system through customized design to ensure that the solvent residue meets strict standards such as food packaging, and at the same time improve drying efficiency.

3. Hot pressing composite: forming a firm material bond

When the substrate has been dried and the residual solvent has dropped to the safe range, it enters the hot pressing compounding stage. In this link, the dried glue coating substrate and another layer of substrate are closely bonded under the joint action of the heating roller and the rubber press roller. The surface temperature of the heating roller is usually maintained at 80℃ - 120℃, and the rubber press roller provides a pressure of 0.3 - 0.8MPa. The high temperature and high pressure promote the fully fusion of the adhesive molecules with the substrate molecules, forming a firm chemical bond or physical winding, achieving permanent recombination of two or more layers of materials. This hot press bonding method not only imparts excellent barrier properties, mechanical strength and weather resistance to the composite material, but also ensures that the composite surface is flat and bubble-free, meeting the appearance and performance needs of high-end packaging products.

Solvent Based Dry Laminating Machine achieves efficient volatilization and reliable bonding of solvent-based adhesives through precise coating, drying and hot pressing processes. The technical support of professional customized suppliers provides enterprises with stable and efficient solutions in packaging production, promoting the industry to continuously develop towards intelligence and greenness.
