Maintenance and Care of Plastic Bottom-Sealed Bags

　　Plastic Bottom-seamed pocket Its advantages and performance are becoming increasingly well known. At the same time as plastic woven bags are produced and consumed on a large scale, it is also important to understand the precautions for their simple maintenance and proper storage. So how can we, to a certain extent, slow down the aging of plastic sewn-bottom bags and thereby extend their service life? Next, let’s examine the monitoring of the anti-aging performance of plastic sewn-bottom bags.

　　Test the aging performance of seam-sealed bottom pockets.

　　Plastic sewn-bottom bags primarily include polypropylene bags and polyethylene bags, and are currently widely used as packaging materials for express parcels, fertilizers, cement, rice, chemical products, and other goods. The aging resistance of plastic sewn-bottom bags can be evaluated through accelerated laboratory aging tests and outdoor weathering exposure tests.

　　In artificial aging tests, plastic seam-bottom bags are exposed to simultaneous or alternating influences of light, oxygen, heat, and humidity while being placed in the testing equipment. Under these conditions, the principal environmental parameters tend to remain relatively stable, thereby ensuring good reproducibility of the obtained data.

　　So, flood control Bottom-seamed pocket What precautions should be taken when using it?

　　The production of flood-control bottom-seam bags involves the use of certain composite materials and manufacturing techniques, resulting in convenient and relatively stable performance. However, under specific adverse conditions, even minor carelessness can lead to product damage. During storage and transportation, packaged products should be kept out of direct sunlight as much as possible, since prolonged exposure can reduce the tensile strength of the woven bag itself. Currently, the structural integrity of flood-control bottom-seam bags and similar products on the market has improved significantly. Despite these substantial quality enhancements, users must still exercise due caution and take appropriate protective measures during operation.

　　In addition, the precautions we take during use should also extend to the concept of environmental protection. After using sealed-bottom packaging bags, in order to prevent discarded bags from taking up unnecessary space, we should properly dispose of them. We can either hand them over to specialized waste-recycling companies or allow them to biodegrade naturally in an appropriate manner. However, in some areas, certain practices are still widely employed: burning these materials to facilitate production, which can cause considerable harm to the environment as a whole.

　　 Bottom-seamed pocket The fading that occurs during use can be analyzed from the following aspects: 1) inadequate surface corona treatment; 2) excessively high temperature and relative humidity in the printing workshop; and 3) significant differences between the ink system’s solubility-related hydrogen-bonding forces and those of the woven-bag substrate. Due to these factors, printing on bottom-seamed bags is often suboptimal, leading to ink fading. During the production of bottom-seamed bags, it is essential to control the relative humidity in the workshop as much as possible, while ensuring it does not fall too low. When relative humidity drops below 40%, static electricity is more likely to occur.

　　During the production of bottom-sealed bags, relative humidity in the workshop should be controlled as much as possible, but not allowed to drop too low. When it falls below 40%, static electricity is likely to occur. Corresponding adjustments must be made to factors such as bag geometry, temperature, humidity, and ink selection.
