In recent years, octagonal sealing packaging bags have gained great popularity in the market, especially in the field of nut packaging. However, this type of packaging bag has a relatively high cost. To ensure the effectiveness and economic benefits of its use, the following provides professional explanations on the selection and maintenance points.
I. Key Points for Purchase
Printing Quality
Check if there are any unexpected additional colors in the color superimposition area and assess the degree of pattern restoration. The higher the level of realism, the better. At the same time, carefully examine whether there are printing defects such as wire drawing, foggy printing, blocked printing, or missed printing.
2. Material Hygiene and Safety
A qualified octagonal sealing packaging bag should have no unpleasant odor. Such an odor usually indicates that the material may not meet hygiene standards and could even affect the packaging function.
3. Sealing Strength and Durability
A high-quality packaging bag should have high mechanical strength and be resistant to being torn by human hands. If the heat-sealed area can be uniformly torn from the middle of the seal, it indicates that the heat sealing process is defective and is prone to causing package breakage during production and distribution; if the tearing occurs at the edge of the seal, it indicates good heat sealing quality.
4. Appearance and Form
The packaging bag should have good stiffness and flatness, with smooth and neat cut edges without frayed edges, to ensure stability during subsequent processing and usage.
II. Maintenance Suggestions
1.Storage Environment
The packaging bags should be stored in a dry and well-ventilated place to prevent moisture absorption or chemical deterioration, ensuring that their performance remains unaffected.
2. Temperature Control
Although some packaging materials have certain heat and cold resistance properties, it is still recommended to avoid extreme temperature conditions to prevent changes in material performance.
3. Store in a dark place
Ultraviolet rays can accelerate the aging of packaging materials. Therefore, when storing, it should be kept away from direct sunlight to extend its service life.
By implementing the above professional selection and maintenance measures, the usage efficiency and economic performance of the octagonal sealing packaging bags can be effectively enhanced.
