We are closer to the Mid-Autumn Festival. Now, a lot of moon cake manufacturers have begun to produce moon cake, ready for the arrival of the Mid-Autumn Festival. Moon cake requirements of the shelf life is relatively long, so generally are using high barrier packaging. Commonly used structures are KPA / CPP, KOP / CPP and so on.
Vacuum packaging of moon cakes, generally used to compare the larger size of the moon cake packaging. Why? Because the regular moon cake skin is relatively soft, which contains air, if the use of vacuum packaging, will lead to moon cake deformation, so the cakes rarely use vacuum packaging (compressed biscuits can, because it is dense); and moon cake manufacturers to do the pie, In general are relatively stiff, can withstand the pressure of vacuum packaging. And the use of vacuum packaging, can effectively reduce the volume of moon cake packaging to facilitate the follow-up packaging process, and the appearance of more beautiful.
Vacuum packaging of the moon cake, is generally used KPA / CPE composite structure. As we all know, PA / PE is a conventional vacuum bag composite structure, with excellent air insulation function. In addition to the enhanced coating of the individual barrier properties of the K-coating, this vacuum-type mooncake bag has this and its excellent packaging performance.
