　　1. The thickness and thickness uniformity of the finished product mainly depend on the thickness and uniformity of the single-layer film before the vacuum packaging bag is compounded. That is to say, controlling the thickness and quality of the single-layer film of the vacuum packaging bag is the prerequisite for obtaining the qualified thickness and quality of the finished product.

　　2. For the composite vacuum packaging bag film with the same inner layer material, the higher the thickness is, the higher the initial heat sealing temperature is, and vice versa. That is to say, the composite vacuum packaging bag film with uniform thickness can obtain uniform sealing quality and avoid local poor heat sealing.

　　3. The barrier property of the vacuum packaging bag film is closely related to the thickness of the vacuum packaging bag film (generally proportional to the thickness). The vacuum packaging bag film with good uniformity can obtain uniform and stable barrier property.

　　4. The film thickness uniformity of the vacuum packaging bag directly affects the mechanical tensile properties of the film. The vacuum packaging bag film with good thickness uniformity can obtain better printing overprint accuracy and composite quality.

　　5. Most customers take square meters as delivery data, which can effectively control the processing cost of composite film.
