The weaving process of PP Zipper woven bag

The weaving process of PP Zipper woven bag is a crucial link in its manufacturing process, which directly affects the overall quality, strength and durability of the bag.
Raw material preparation:
The first step in manufacturing PP Zipper woven bags is to prepare polypropylene (PP) raw materials. Polypropylene is a high molecular polymer whose granular material will be melted and formed into woven filaments during the bag making process. The selection and quality of these raw materials are directly related to the final performance of the bag.
Extrusion molding:
In the extrusion molding stage, polypropylene pellets are fed into the extruder, where they are melted into liquid polypropylene under conditions of high temperature and pressure. Molten polypropylene is pushed through the extruder's screw and into a nozzle, where it forms filaments. These filaments will become the raw material for subsequent weaving.
Stretching and cooling:
After extrusion, the filament is stretched through a stretching mechanism to increase its length and pulling force. Then, the stretched filaments are quickly cooled through a cooling device to solidify them into a tough filament-like material.
Knitting machine knitting:
The knitting machine is the core equipment in the manufacturing of PP Zipper woven bags. On a knitting machine, the extruded, stretched and cooled filaments are cross-woven into a flat fabric. The weaving density and weaving method in this process directly affect the strength and durability of the bag. Generally speaking, a tighter weave will increase the load-bearing capacity of the bag.
Warp and weft stretching:
After weaving is complete, the fabric may need to be stretched in the warp and weft directions. This step is accomplished using a stretching machine designed to adjust the size and shape of the bag to ensure it meets specific design requirements. This also helps further improve the strength and stability of the bag.
Winding and cutting:
After weaving is completed, the fabric is sent to the winding machine and wound into rolls. Next, it is cut by a cutting machine according to the desired bag size. This step not only ensures the consistency of the bag, but also prepares it for the next step in the bag making process.

Performance and functions of PP Zipper woven bag

PP Zipper woven bag is an advanced product widely used in the packaging industry, and its performance and functionality have been widely recognized.
Strength and wear resistance:
PP Zipper woven bag is made of polypropylene (PP) material and made through precise weaving process, so it has excellent strength and wear resistance. This enables the bag to withstand greater weight and maintain durability in different environmental conditions, making it suitable for a variety of heavy-duty and wear-resistant packaging needs.
Tear resistance:
Due to the selection of polypropylene material and the superiority of the weaving process, PP Zipper woven bag exhibits excellent tear resistance. This means that the bag is less likely to tear during transportation and use, effectively protecting packaged items from damage.
Waterproof and moisture-proof:
Polypropylene itself has good waterproof properties, and the woven structure of PP Zipper woven bag further improves its waterproof and moisture-proof properties. This allows the bag to effectively protect packaged items in humid or rainy environments, ensuring they remain dry and of high quality.
Breathability:
The weaving process gives the PP Zipper woven bag good air permeability, which helps the packaged items stay fresh in the package. Breathability also plays an important role in ventilation during storage and transportation of certain products, such as produce.
Convenient zipper design:
PP Zipper woven bag is equipped with a convenient zipper design, making it easier to open and close the bag. This allows users to easily access packaged items, improving packaging convenience, especially in scenarios that require frequent opening and closing.
Multifunctional application:
Due to its superior performance and functionality, PP Zipper woven bags are widely used in the food industry, chemical industry, agriculture and other fields. It is suitable for different types of commodity packaging, including grain, fertilizers, chemical products, etc., providing reliable packaging solutions for various industries.
