Difficulties: a vacuum in the vacuum packaging technology of flexible packaging on the barrier property of packaging material requirements, than the average 10000 times lu: su composite material of high barrier property, such a high barrier property by common composite materials and composite technology is difficult to meet the requirements.

Generally need to use very thick aluminum foil, and USES 4 to 7 layers of structure of composite materials, integrated application of various composite technology.
Flexible packaging of vacuum packaging technology difficult point 2: composite lining heat sealing materials of choice.
Vacuum packaging technology difficulties of three of flexible packaging: packaging design more difficult.
Flexible packaging vacuum bags  of the technical difficulties of four: vacuum packaging materials determine the quality of the cycle is long.
If you want to order the vacuum bags, aluminum foil bags, anti-static bags, compound bags, packaging bags, please contact contact LRPACK.
