What are the seam treatment methods of ADULT EVA RAINCOAT, and what are their advantages?

The seam treatment methods of ADULT EVA RAINCOAT mainly include heat-sealed seams, taped seams, sewn seams and welded seams. These treatment methods each have their own unique advantages and applicable scenarios, ensuring the waterproofness, durability and aesthetics of the raincoat in different use environments.

Heat-sealed seams are made by melting the EVA material at the seams with high-temperature equipment, so that they are fused together to form a seamless connection. The biggest advantage of this treatment method is its excellent waterproof performance. Heat-sealed seams can achieve complete waterproofness, prevent rainwater from seeping through the seams, and ensure that the wearer can stay dry even in heavy rain. In addition, the heat-sealed seams are highly firm and not easy to crack or fall off, which extends the service life of the raincoat. Due to the characteristics of seamless connection, the raincoat after heat sealing has a neat and beautiful appearance, which is very suitable for users who have high requirements for appearance.

Taped seams are to paste waterproof strips at the seams and fix the strips by hot pressing or cold pressing. The advantage of this treatment method is to enhance the waterproof performance. The adhesive strips cover the seams, effectively preventing rainwater from penetrating and providing an additional layer of protection. The adhesive strips have a certain degree of elasticity, adapting to various stretching and bending of the raincoat, increasing the flexibility and comfort of the raincoat. If the adhesive strips are worn or fall off, they can also be easily replaced or repaired, extending the use time of the raincoat. Raincoats with taped seams are particularly suitable for outdoor activities and sports occasions because they can adapt to frequent movements and stretching.

Sewing seams are sewn together by sewing machines. The seams can be sewn with single seams, double seams or multiple layers, providing a variety of options. The advantages of sewing seams are that they are low in cost and simple in process, suitable for large-scale production, and reduce production costs. At the same time, sewing thread can provide good tensile strength, enhance the overall firmness of the raincoat, and is not easy to tear or break during use. In addition, sewing thread can also be used for decorative design, increasing the beauty of the raincoat through lines of different colors and styles. Raincoats with sewing seams are suitable for daily commuting and light outdoor activities, taking into account both practicality and fashion.

Welded seams use energy such as high-frequency radio waves or ultrasound to melt the EVA material at the seams to form a strong welded seam. The advantage of this treatment method is its high-strength connection and excellent waterproof performance. Welded seams are strong and durable, suitable for raincoats that require high-strength seams, such as those used in severe weather conditions. Welded seams can achieve pinhole-free and gap-free connections, providing top-level waterproof protection and ensuring that the wearer stays dry even in extreme weather. At the same time, no chemical adhesives are used in the welding process, which is harmless to the environment and the human body, making it an environmentally friendly seam treatment method.
