You use the dry lamination method in flexible packaging to stick two materials together without using wet glue. A dry laminator puts a liquid adhesive on one material. It dries the adhesive. Then it joins this material to another layer with heat and pressure. This process makes a strong and dependable bond. Today, more companies pick flexible packaging because it fits modern needs. Over 63% of FMCG packaging now uses these solutions. Many products use recyclable or compostable materials. Dry lamination helps you follow these trends and give high-quality packaging.
Dry lamination uses heat and pressure to stick materials together. It does not use wet glue. This method is clean and quick. It works well for flexible packaging.
The process starts with getting the materials ready. Then, adhesive is put on. Next, the adhesive is dried. After that, the films are pressed together. The product is cooled and rolled up at the end.
Dry lamination is used a lot for food and home product packaging. It makes strong seals. These seals keep out air and water.
Picking the right adhesive is very important for good bonding. Water-based acrylics are often chosen. They are safer and better for the environment.
Dry lamination can help save money. It also cuts down on waste. This makes it a smart choice for companies that want better packaging.
A dry laminator joins two or more flexible films. This machine does not use wet glue. It puts a thin layer of adhesive on one film. The adhesive dries before the films are pressed together. This makes the process fast and clean.
A dry film laminator has many important parts. Each part helps the dry film lamination work well. The table below shows the main parts and what they do:
| Component | Description |
|---|---|
| Unwinding Systems | These feed the films into the machine and keep them straight. |

| Drying System | It uses heat to dry the adhesive before the films are joined. |
| Lamination Nip | This presses the films together using heat and pressure. |
| Rewinding System | It rolls up the finished laminated film. |
| Auxiliary Systems | These help control tension, guide the film, cool it, and check for quality. |
Every part of the dry film laminator helps the process go smoothly. The machine lets you control heat, pressure, and speed. This helps you make packaging that is high quality.
Dry film lamination is used in many industries. This method helps make packaging that keeps products safe and fresh. Dry laminators are best when you need strong, clean, and fast bonds.
Here are some ways dry film lamination is used in flexible packaging:
Food packaging, like pet food, dry goods, frozen food, candy, and coffee
Household products, such as wipes, cosmetic items, and cleaning product refill sachets
You can use dry film laminators for many types of packaging. Dry film lamination makes strong seals and keeps out air and moisture. The packaging looks nice and protects your product. Many companies use dry film lamination because it fits modern packaging needs.
Let’s see how the dry laminator works step by step. This method joins flexible films without using wet adhesives. The process is clean, quick, and makes strong bonds.
Here are the main steps in dry film lamination:
Material Preparation
First, you pick the films or substrates you want to use. These can be plastic films, foils, or paper. You must make sure the surfaces are clean. There should be no dust or oil.
Adhesive Application
Next, you put a thin layer of adhesive on one film. In dry laminating, you often use self-adhesive films or adhesive powders. Sometimes, you use films that already have adhesive. These only need heat or pressure to work.
Drying
The film with adhesive goes through a drying system. The machine uses heat to take away moisture or solvent from the adhesive. This step makes sure the adhesive is dry before joining the films.
Bonding
Now, you bring the two films together. The dry laminator uses heat and pressure to stick them. This makes a strong and even seal between the layers.
Cooling and Rewinding
After bonding, the laminated film cools down. The machine rolls up the finished film. It is now ready for use or cutting.
Tip: Always check if your films are clean before you start. Clean films help stop bubbles and weak spots in the final product.
You control some important things during dry film lamination. These settings help you get the best results and stop problems like bubbles, wrinkles, or weak bonds.
| Parameter | Range |
|---|---|
| Composite Roller Temp. | 50°C - 70°C |
| Composite Pressure | 0.3 - 0.4 MPa |
| Glue Application | 3.7 - 3.8 g/m² |
You must watch these settings closely. The right temperature and pressure help the adhesive stick well. Too much heat or pressure can cause wrinkles or color changes. Too little can make the bond weak.
In dry film lamination, you do not use liquid adhesives. You use films with adhesive already on them or hot-melt binders. This keeps the process clean and safe for you and the environment. It also lowers the chance of problems like bubbles or glue not drying.
You might have some problems during dry laminating:
Weak bonding
Bubbles or trapped air
Wrinkles in the laminate
Ink bleeding or color change
You can fix many of these by changing the process settings. For example, slow down the machine to let air out. Or raise the drying temperature to remove more moisture.
The adhesive you pick changes how your flexible packaging works. You should choose adhesives that bond well, bend easily, and resist chemicals or heat. Water-based acrylics are popular because they are safer and better for the environment than solvent-based ones.
Note: Always pick an adhesive that fits your packaging needs. The right adhesive helps you avoid problems and makes sure your packaging works well.
If you know how each step works and control the process, you can use dry film lamination to make strong, nice-looking, and reliable flexible packaging.
