The modified atmosphere packaging produced by the modified atmosphere packaging machine fails to achieve a good shelf life. Is it penetration or leakage? You may have just spent tens of thousands of dollars developing a revolutionary one-dose new infant milk powder product for the infant and toddler

In order to extend the shelf life of food, new packaging technologies that are constantly developed, such as modified atmosphere packaging, anti-mold packaging, moisture-proof packaging, anti-fog packaging, anti-static packaging, selective breathable packaging, non-slip packaging, buffer packaging,

1. The secret behind fresh fish is of course keeping it cold - close to zero. But even if you manage to stay close to zero, the fish will still start to spoil. Bacteria in the flesh can change the color of the fish and start to taste bad. Oxygen is one of the enemies because some bacteria need oxyge

新鲜果蔬气调包装保鲜原理 新鲜果蔬用透气性塑料薄膜包装密封后，果蔬的呼吸活动消耗包装内空气中的O2并产生差不多等量的CO2，逐渐构成包装内与大气环境之间的气体浓度差。空气中的O2通过塑料薄膜渗透入包装补充消耗的O2，包装内的CO2则渗透出塑料薄膜扩散到空气中，开始时，包装薄膜内外的气体浓度差小，渗入包装内的O2不足以抵消消耗的，渗出的CO2小于产生的CO2。随着贮藏过程中包装内外气体浓度差增加，气体渗透的速度加快。当包装内O2消耗速度等于O2渗入速度，而CO2产生的速度等于渗出的速度时，包装内可能达到一个低02和低C02气调平衡浓度。如果包装内的气体平衡浓度使果蔬仅产生微弱的需氧呼吸而没有厌

Modified atmosphere packaging machines are typically two to three times larger than other forms of packaging, resulting in higher logistics and storage costs. However, if a mixture of nitrogen, oxygen and carbon dioxide is used to replace the air and stored at the correct temperature, it can reduce
