The importance of the thickness of the transparent vacuum packaging bag for food packaging 1. The thickness and uniformity of the food vacuum bag mainly depend on the thickness and uniformity of the single-layer film before the packaging bag is compounded, that is to say, the thickness of the single-layer film of the vacuum packaging bag is well controlled. Thickness quality is the condition for obtaining qualified food thickness quality; the thickness of vacuum bags on the market is 16 wires, 20 wires, 24 wires, 32 wires, etc. YLTpacking packaging can also be customized according to customer requirements! 2. The barrier property of vacuum food packaging film is closely related to the thickness of vacuum packaging bag film (usually proportional to the thickness), and the vacuum bag film with good uniformity can obtain uniform and stable barrier property. 3. The thickness uniformity of vacuum food packaging film directly affects the mechanical stretching function of the film. The vacuum bag film with good thickness uniformity can achieve better printing overprint accuracy and composite quality. 4. For the vacuum bag film with the same inner material, if the thickness is too high, the heat sealing temperature will be too high, and vice versa. That is to say, the composite vacuum bag film with uniform thickness can achieve uniform sealing quality and prevent partial heat sealing failure.
