the importance of vacuum packing bag thickness control (1) products depends on thickness and thickness uniformity of the primary aluminum foil bag vacuum packing bag before the compound single-layer film thickness and uniformity, that is to say, manipulation of the good quality of vacuum bags the thickness of single layer film thickness of qualified products quality is achieved.
the importance of vacuum packing bag thickness control (2) the barrier property of vacuum packaging film is closely related to the thickness of the vacuum packaging film, Which is proportional to the thickness of contact) Uniformity, good vacuum packaging film can obtain homogenous good barrier property.
the importance of vacuum packing bag thickness control (3) vacuum packaging film thickness uniformity directly affects the mechanical drawing function of thin film, thickness uniformity good vacuum packaging film can achieve good printing overprint precision and quality of composite.
the importance of vacuum packing bag thickness control (4) as lining material of vacuum bag film, thickness on the high side began to heat sealing temperature is high, and vice versa. That is to say, the thickness of composite vacuum packaging film is uniform sealing quality can be achieved, prevent part of the heat sealing is undesirable.
