Do plastic packaging bags have a shelf life?

        ●  What is the shelf life of plastic packaging bags?

            ○  The shelf life of plastic packaging bags refers to the period during which various performance indicators (such as mechanical properties, barrier properties, hygiene properties, etc.) of the packaging bags can meet the requirements for use under certain conditions. Generally speaking, the shelf life of plastic packaging bags is 2-3 years. Beyond the shelf life, the performance of the packaging bag may decrease, and even damage, aging, and other phenomena may occur, affecting the effectiveness of use.

        ●  Factors affecting the shelf life of plastic packaging bags

            ○  Raw materials: The quality of plastic packaging bags directly affects their shelf life. Packaging bags made from high-quality raw materials have a relatively long shelf life; On the contrary, it is shorter.

            ○  Production process: The production process also has a significant impact on the shelf life of plastic packaging bags. By adopting advanced production processes and equipment, the stability of packaging bags can be improved and the shelf life can be extended.

            ○  Storage conditions: The storage conditions of plastic packaging bags have a significant impact on their shelf life. The storage environment should be kept dry and ventilated, avoiding direct sunlight and high temperatures to prevent aging of the packaging bags.

            ○  Usage frequency: The higher the usage frequency of plastic packaging bags, the faster their loss rate and the corresponding shortened shelf life.

            ○  Handling and loading/unloading: Improper handling during the handling and loading/unloading process may cause damage to the packaging bags, affecting their service life.

        ●  How to determine if a plastic packaging bag has expired?

            ○  Observe the appearance: Expired plastic packaging bags may have cracks, deformations, discoloration, and other phenomena on the surface.

            ○  Check performance: Observe whether the mechanical properties of the packaging bag have decreased through simple stretching and compression tests.

            ○  Smell: If the packaging bag has an odor, it may be caused by aging of the raw materials, indicating that it has expired.

        ●  How to extend the shelf life of plastic packaging bags?

            ○  Choose high-quality raw materials: When purchasing plastic packaging bags, choose reputable manufacturers to ensure the quality of raw materials.

            ○  Proper storage: Follow the above storage conditions to avoid premature aging of packaging bags.

            ○  Reduce usage frequency: Reduce the usage frequency of packaging bags appropriately to extend their service life.

            ○  Pay attention to handling and loading/unloading: During the handling and loading/unloading process, handle with care to prevent damage to the packaging bags.
