Causes and Solutions for Carton Mold

Causes and Prevention Methods of Carton Mold
As an indispensable packaging material in daily life and the logistics industry, the quality stability of cartons directly affects the safe transportation and storage of products. However, in damp and warm environments, cartons are highly susceptible to mold, which not only affects their appearance but may also damage the goods inside. This article will explore the causes of carton mold from three aspects: carton material, environmental conditions, and microbial activity, along with preventive measures.

1. The Relationship Between Carton Material and Mold

Cartons are primarily made of cardboard, whose main components are plant fibers such as wood pulp, straw pulp, or recycled fibers. These natural fibers contain abundant nutrients like starch, hemicellulose, and lignin, which can easily become a "feast" for microorganisms under suitable conditions. Especially when adhesives or additives used in the cardboard contain organic substances such as sugars and proteins, the risk of microbial growth increases. Additionally, the surface roughness and porosity of the cardboard affect its moisture absorption and breathability, thereby influencing the likelihood of mold. Rough surfaces and high porosity make the cardboard more prone to absorbing moisture from the air, creating favorable conditions for mold growth.

2. The Mechanism of Microbial Activity

Carton mold is the result of the combined action of various molds. These molds spread through spores in the air. Once they encounter suitable environmental conditions, the spores germinate and develop hyphae, which then erode the fiber structure of the carton. During their growth, molds secrete various enzymes, such as cellulase and hemicellulose, which break down organic substances like cellulose in the carton, providing energy and nutrients for mold growth. At the same time, mold growth produces various metabolites, such as pigments and toxins, which not only affect the appearance and physical properties of the carton but may also contaminate the packaged goods, posing risks to human health.

3. Preventive Measures

To prevent carton mold, we can take the following measures:

1. Control environmental conditions: Keep warehouses or storage environments dry and well-ventilated. Use dehumidifiers, air conditioners, and other equipment to regulate temperature and humidity, ensuring environmental humidity remains below 65% RH and the temperature is within an appropriate range.

2. Use mold inhibitors: Add an appropriate amount of iheir66 mold inhibitor during the carton production process to inhibit mold growth. However, it is important to ensure that the chosen mold inhibitor meets environmental and safety requirements to avoid harm to the environment and human health.

3. Regular cleaning and sterilization: Regularly clean and sterilize warehouses and storage areas. Evenly spray iHeir-Spray mold and antibacterial agent into the air, especially in corners and damp, dark areas. Then, seal the area for 12-24 hours and arrange for employees to open windows and doors for ventilation 30 minutes in advance before entering the warehouse. When mopping the floor, add 5% iHeir-Spray mold and antibacterial agent to the mop water and mop once to eliminate any potential mold spores and sources of contamination.
