The importance of vacuum packaging bag thickness control
Nov 29, 2018

       Some friends may not understand why different products use vacuum bags of different thicknesses. In fact, vacuum bag thickness control is very important. How important is it?

       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, that is to say, controlling the thickness quality of the single-layer film of the vacuum packaging bag is the premise of obtaining the quality of the qualified finished product.

       2 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), and the uniformity of the vacuum packaging bag film can obtain uniform and stable barrier properties.

       3 The thickness uniformity of the vacuum packaging bag directly affects the mechanical tensile properties of the film, and the vacuum packaging bag film with good thickness uniformity can obtain better printing overprinting precision and composite quality.

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