Some friends may not understand why different products to use different thickness of the vacuum bag. In fact, vacuum bag bag thickness control is very important. How important is it?
The thickness and thickness uniformity of the finished product mainly depends on the thickness and uniformity of the single layer film of the vacuum bag, that is to say, the thickness quality of the single layer film of the vacuum bag is the prerequisite for obtaining the finished product thickness quality.
The barrier properties of the vacuum packaging bags are closely related to the thickness of the vacuum packaging bags (generally in direct proportion to the thickness), and uniform vacuum bags can achieve uniform barrier properties.
Vacuum packaging film thickness uniformity directly affect the mechanical properties of the film tensile properties, good thickness uniformity of the vacuum bag film can get a better printing overlay accuracy and composite quality.
The same inner layer of composite vacuum packaging bag film, the thickness of the high heat sealing temperature is high, and vice versa. In other words, the uniform thickness of the composite vacuum packaging bags can get a uniform sealing quality, to avoid local heat sealing bad phenomenon.
