Pros and Cons of Plastic Bottom-Sealed Bags

　　 Bottom-seamed pocket It is a common filling product in both industrial and agricultural applications, and further specialized applications of plastic-seamed bottom bags are even more extensive. Plastic-seamed bottom bags mainly include polypropylene bags and polyethylene bags. Based on the sewing method, they can be classified into seamed-bottom bags and seamed-edge bags. Currently, they are widely used as packaging materials for fertilizers, chemical products, and other goods. So why are plastic-seamed bottom bags so widely used? The following section will provide a detailed explanation.

　　Plastic-sealed bottom bags have gained widespread acceptance primarily due to the following advantages:

　　1. Can be used as packaging bags for agricultural products.

　　Due to product availability and pricing considerations, 6 billion sewn-bottom bags are used annually for cement packaging, accounting for more than 85% of bulk cement packaging. With the development and increasing application of flexible intermediate bulk containers (FIBCs), plastic sewn-bottom bag FIBCs have become widely employed in the maritime and land transportation sectors for packaging industrial and agricultural products. In agricultural product packaging, plastic sewn-bottom bags are extensively utilized for seafood packaging, poultry feed packaging, agricultural mulch materials, and shade, windbreak, and hail-protection shelters for crop cultivation. A commonly used product is the woven feed bag.

　　2. Can be used as food packaging bags.

　　Rice, flour, and other food products are gradually being packaged in woven bags. Common Bottom-seamed pocket Available: rice woven bags, flour woven bags, corn woven bags, and other types of woven bags.

　　3. For tourism and transportation.

　　Temporary tents, umbrellas, various types of travel bags, and other similar items. In the tourism industry, plastic-woven fabrics are commonly used. Various tarpaulins are widely employed as covering materials for transportation and storage—replacing cotton tarpaulins—which are prone to mold and heavy in weight; plastic-woven fabrics are also extensively utilized for fencing and netting in construction. Common examples include logistics bags, logistics packaging bags, freight bags, and freight packaging bags.

　　In addition, plastic geotextile-lined bags are indispensable in flood control and disaster relief efforts, as well as in the construction of embankments and riverbanks.

　　In addition to plastic-seamed-bottom bags, paper-plastic composite bags—also known as three-in-one composite paper bags—are small bulk containers primarily designed for manual handling or mechanized transport. They are particularly convenient for transporting small volumes of powdered and granular materials using forklifts, and boast high strength, excellent water resistance, an attractive and elegant appearance, and easy loading and unloading. As such, they are among the most popular and practical packaging materials available today.

　　Plastic composite bags typically feature a white or yellow kraft paper outer layer and a plastic-sealed bottom. The PP plastic pellets melt under high temperature and pressure, bonding the kraft paper to the plastic woven fabric; an inner liner bag can also be added. This paper-plastic composite construction effectively creates a gusseted bottom at the seam, offering excellent strength as well as water- and moisture-proof properties.

　　That concludes the discussion on plastics. Bottom-seamed pocket An overview of the advantages and disadvantages is provided here, with the hope that this information will be helpful to all.
