Stacking bag break, sealing site leakage

  Stacking bag breakmeans that the food packaging should be able to withstand a certain stackingforce during transportation and storage, otherwise the food packaging will bebroken. Sealing crack generally refers to lax sealing, packaging opening, bottlemouth seepage, bottle mouth leakage, and plastic bottle mouth bursting. Packagingof substandard quality will cause the above issues:

1) Inferior physicaland mechanical properties - such as packaging materials are weak to punctures;or tearing and piercing during the storage, transportation and selling. If thedamages were not discovered in time, the food would be exposed to a largeamount of oxygen which may lead to oxidation and deterioration. If the packagingmaterial is the weak to low temperature, when it is subject to coldenvironment, the original physical and mechanical properties will be diminished,and brittle rupture may occur.
2) Poor sealing strengthat the sealing site – when the heat sealing strength of the flexible packagingmaterial is too large, the package is easy to crack at the bottom of the sealingsite; when the heat sealing strength is too low, it will cause the sealing tocrack; if the torque of the bottle cap is not appropriate, and the bottle mouthis likely to leak.
