The Importance of Vacuum Bag Thickness Control

1. The thickness of the finished product and thickness uniformity mainly depends on the vacuum bag composite before the thickness and uniformity of the single-layer film, that is to say, control the thickness quality of the vacuum bag single-layer film is the prerequisite for obtaining qualified finished product thickness quality.

2. The same inner material of the composite vacuum bag film, high thickness then the starting heat seal temperature is high, and vice versa. In other words, the thickness of the composite vacuum bag film can obtain a uniform sealing quality, to avoid local heat sealing undesirable phenomenon.

3. Vacuum bag film barrier and vacuum bag film thickness is closely related (generally proportional to thickness), uniform vacuum bag film can obtain a uniform and stable barrier.

4. Vacuum bag film thickness uniformity directly affects the mechanical stretching performance of the film, thickness uniformity of the vacuum bag film can obtain better printing overprinting accuracy and composite quality.

5. Most customers are based on square meters as delivery data, can effectively control the processing costs of composite film.

Vacuum bag thickness control is very important, need manufacturers to strictly control.
