PET lunch box sandwich packaging box is a common plastic packaging product, widely used in food, cosmetics, electronic products and other industries. In order to ensure the quality of blister packaging products and extend their service life, correct storage is very important. Here are some guidelines on how to effectively store PET lunch boxes sandwich packaging boxes.

1.Temperature control

PET (polyethylene terephthalate) is sensitive to temperature fluctuations. It is best to store PET lunch boxes sandwich packaging boxes in a controlled environment away from extreme heat or cold. Exposure to high temperatures can cause packaging to warp or deform, while extreme cold can make the material brittle and prone to cracking, affecting its effectiveness.

2. Keep away from direct sunlight

Ultraviolet radiation from sunlight degrades PET over time, causing the material to discolor and weaken. Store PET lunch boxes sandwich packaging boxes in a dark or shaded area to minimize exposure to sunlight.

3. Moisture-proof and moisturizing

PET lunch boxes and sandwich packaging boxes are highly sensitive to moisture and tend to absorb moisture in humid environments, leading to problems such as deformation and mold. Therefore, when storing PET lunch boxes and sandwich packaging boxes, try to avoid contact with water or humid places. You can choose to use hygroscopic substances such as moisture-proof agents and desiccants and place them in storage boxes or bags to absorb moisture and moisturize.

4. Avoid stress

PET lunch boxes and sandwich packaging boxes are usually made of film and are easily deformed by external pressure. During storage, avoid placing other heavy objects on top of the blister packaging products to avoid deformation, damage, etc.

5. Avoid exposure to chemicals

PET lunch boxes and sandwich packaging boxes usually come into contact with cosmetics, food and other items, so contact with corrosive and harmful chemicals should be avoided during storage. This can prevent PET lunch boxes and sandwich packaging boxes from being corroded by chemicals, affecting their quality and safety.

6. Pay attention to fire prevention

PET lunch boxes and sandwich packaging boxes are plastic products that burn easily and release some toxic gases when exposed to open flames or high temperatures. Therefore, when storing PET lunch boxes and sandwich packaging boxes, avoid contact with open flames, stay away from fire sources, and try to maintain ventilation.

To sum up, the correct storage of PET lunch boxes and sandwich packaging boxes is crucial to maintaining their quality and extending their service life. By controlling the temperature of the storage environment, storing away from light, moisture-proof and moisturizing, avoiding heavy pressure, avoiding contact with chemicals and paying attention to fire prevention, etc., you can ensure the integrity and safe use of PET lunch boxes and sandwich packaging boxes.
