During the warm season, outdoor parcel lockers can pose a serious risk to the quality of your shipments. Direct sunlight and heated metal surfaces create an environment where the inside temperature of the locker can exceed +40 °C, even if the outdoor air temperature is only +20 °C. Just like in a car left in the sun, the temperature can rise rapidly – and the result may be irreversible damage to the contents of your parcel.
But heat is not the only issue. Rain and high humidity can also make outdoor lockers a poor environment for parcels such as paper goods, food, or electronics. Water vapor can seep into boxes, moisture can damage the packaging, and condensation may cause issues with devices or printed materials.
How Temperature and Humidity Affect Your Shipment
Many everyday products are sensitive to both heat and humidity. For example:
Cosmetics may change texture, lose their fragrance, or become ineffective;
Medications and supplements can become less effective or even harmful;
Food items may spoil or lose their taste;
Electronics, aerosols, and photo equipment can be damaged by heat or become unsafe in humid conditions;
Books and printed materials may get wet, warp, or lose their quality.
