What are the storage conditions for BOPP thermal synthetic paper?

The storage conditions of BOPP thermal synthetic paper are crucial to maintaining its performance and quality. Here are some key storage conditions:

1. Temperature and humidity control

Temperature: When storing BOPP thermosensitive synthetic paper, the ambient temperature should be controlled within the appropriate range. In general, 23±2 ° C is an ideal storage temperature. Avoid exposing the paper to too high or too low a temperature environment to prevent unnecessary chemical reactions in the heat-sensitive coating, affecting the printing effect or the durability of the paper.

Humidity: Humidity control is also important. It is recommended to store the paper at a relative humidity of RH60-70% (or RH65±5%) to avoid moisture. The humid environment may cause the thermal paper to fade, become sticky or deform, thus affecting its use effect.

2. Lighting and avoiding light

Light: BOPP thermal synthetic paper should be stored in a light environment, avoid direct sunlight or strong light exposure. Prolonged exposure to sunlight accelerates the chemical reaction of the heat-sensitive coating, causing the paper to fade or deteriorate.

Packaging: The use of packaging materials with the function of avoiding light, such as black or dark plastic bags, cartons, etc., can effectively protect the paper from the influence of light. At the same time, ensure that the packaging is well sealed to prevent moisture intrusion.

3. Physical protection

Stacking method: For rolled BOPP thermal synthetic paper, it should be stacked vertically to avoid paper deformation under pressure. Flat sheets of thermal paper should be stored flat to avoid folding or bending.

Height and load bearing: Control the height of each board of paper to avoid excessive pressure on the bottom paper. At the same time, ensure that the paper storage area can withstand the weight of the paper to prevent paper damage due to insufficient bearing capacity.

4. Chemical protection

Avoid chemical contamination: BOPP thermal synthetic paper should be stored away from chemicals and pollution sources. These substances may react with the heat-sensitive coating, causing the paper to degrade or become unusable.

5. Other precautions

Regular inspection: Check the stored BOPP thermal synthetic paper regularly to ensure that the paper is free from moisture, fading, deformation, etc.

First in, first out: Follow the principle of using paper first in, first out to ensure that the paper is fully utilized during its validity period.

In summary, the storage conditions of BOPP thermal synthetic paper include appropriate temperature and humidity control, light and light protection, physical protection and chemical protection. Following these storage conditions can effectively extend the shelf life and service life of the paper.
