The difference between non-woven fabric lamination and coated non-woven fabric.

The production process of non-woven fabric lamination

Non woven fabric lamination is a manufacturing process that covers a layer of film on the surface of non-woven fabric. This manufacturing process can be achieved through hot pressing or coating methods. Among them, the coating method is to coat polyethylene film on the surface of non-woven fabric, forming a film coated non-woven fabric with barrier and reinforcement properties.

The production process of coated non-woven fabric

Coating is a manufacturing process that involves evenly coating plastic slurry onto a substrate and drying it. This manufacturing process can use different substrates, such as paper, plastic film, fabric, etc. Among them, polyethylene is one of the most commonly used substrates.

Comparison between non-woven fabric lamination and coated non-woven fabric

1. Different waterproof performance

Due to the coating method used for non-woven fabric lamination, its waterproof performance is stronger. The waterproof performance of the coating is also very good, but due to the special nature of its production process, there are certain water discharge problems.

2. Different breathability performance

The breathability of non-woven fabric coated with film is better because the film it is coated with is a microporous film that can penetrate water vapor and air. However, due to its better sealing performance and relatively poor breathability, the film is coated.

3. Different flexibility

Due to the fact that the coating is made by drying the plastic slurry, it has better flexibility and bending resistance. The non-woven fabric coating is harder under the protection of the surface film.

4. Different application ranges

Due to the different processing locations of non-woven bag coating and lamination, their application scenarios also vary. Due to the special properties of the film making process, it can be used in many fields, such as making wall panels, clothes hangers, agricultural films, garbage bags, etc. Non woven fabric lamination is mainly used in medical, health, home and other fields.

5. Different processing locations

The difference between non-woven bag coating and lamination lies in the different processing locations. Non woven bag coating generally refers to the reinforcing material at the bottom of the non-woven bag, which is treated with coating to make it waterproof, thus avoiding the erosion of goods by moisture when using non-woven bags in humid environments. And laminating is to cover a layer of film on the surface of the bag, mainly used to enhance the wear resistance of the bag, improve aesthetics and effectiveness.

6. The handling methods are also different

Non woven bag coating is generally used by coating a waterproof material on the bottom of the bag, and then drying to form a coating. And lamination is processed using a laminating machine, which covers a layer of film on the surface of the bag and then undergoes hot pressing treatment to form lamination.

【 Conclusion 】

Although both non-woven fabric lamination and coating are manufacturing processes, they have significant differences and advantages and disadvantages in the production process. Based on actual needs, select suitable processes and materials to maximize their advantages.
