Technical introduction of hot-melt adhesive coater

1. Overview

A skin film hot melt adhesive coating machine is a kind of equipment used to apply hot melt adhesive on skin film materials. This equipment is mainly used in the packaging industry to improve the adhesive performance of packaging materials and ensure that the packaging is firm and reliable. This article will introduce in detail the working principle, application fields, main functions and advantages of the skin film hot melt adhesive coating machine.

2. How it works

The working principle of the skin film hot melt adhesive coating machine mainly includes the following steps:

First of all, hot melt adhesives usually exist in solid form and need to be heated to the melting point by heating equipment to convert them to a liquid state before use. The coating machine is equipped with a heating system, which can accurately control the temperature to ensure that the hot melt adhesive melts evenly.

The melted hot melt adhesive is then evenly applied to the surface of the skin film through the applicator head. The design of the coating head and the accuracy of the control system determine the thickness and uniformity of the coating layer.

In addition, the coated skin film passes through the cooling zone, and the hot melt adhesive cures quickly during the cooling process to form a strong adhesive layer. The cooling zone is usually equipped with a cooling device to speed up the curing process of the hot melt adhesive.

Finally, after the coating is completed, the skin film is rolled into a roll through the winding device for subsequent use.

3. Applications

Skin film hot melt adhesive coating machine is widely used in the following fields:

Food packaging: It is used to package all kinds of food, such as meat, fruits, vegetables, etc., to ensure the sealing and freshness of the packaging.

Pharmaceutical packaging: In the packaging of pharmaceuticals and medical devices, the use of hot melt adhesive coating machines can improve the safety and tightness of the packaging.

Industrial product packaging: It is used for the packaging of industrial products such as electronic products and hardware tools to prevent damage during transportation.

4. Main Functions
