The packaging is usually divided into two categories: one is to promote market sales and the other is to facilitate loading, unloading, storage, storage, and transportation purposes, called industrial packaging. This article will focus on packaging made from polypropylene-pp woven bags. This article first describes the concept of polypropylene woven bags, then outlines its advantages and uses, and then analyzes the dynamics and demands of the polypropylene woven bag market, and finally draws conclusions.
What is a polypropylene woven bag?
Polypropylene (PP) is a thermoplastic resin made by polymerizing propylene. Polypropylene woven bags also include copolymers of propylene and a small amount of ethylene. Polypropylene is usually a translucent colorless solid, odorless and non-toxic. Due to the regular structure and high crystallization of polypropylene, its melting point is as high as 167 ° C. Its finished products can be steam-sterilized is its outstanding advantage. Its density is 0.90g / cm3, which is the lightest general-purpose plastic. Its strength, rigidity, and transparency are better than polyethylene.
Pacific Bags Australia has a wide range of sizes of woven polypropylene bags. These bags are an excellent solution for packing 30-50 KG of dry material. These pouches are made from a woven polypropylene fabric that is strong and resistant to punctures. PP woven sachets are available in laminated or non-laminated forms depending on the material. This material is a commonly used material, which is a translucent material in polypropylene woven bags. When using this material, it will not produce any poisonous effect, and it will not have any odor. We can process pp into plastic woven bags, which are widely used in the packaging industry. When processing this material, woven bag manufacturers need to burn it to its melting point, 167 degrees Celsius, so it will have strong heat resistance when it is used later. Steam will also be used for disinfection so that all products will not be damaged during use. It is worth mentioning that the products made from pp have a very small density, so the product is very lightweight and more convenient for us to use. Moreover, the plastic woven bag made of this material also has high strength and corrosion resistance, so as a popular packaging product now, it is not only lightweight and durable but also can be recycled after use; it is truly a popular packaging product.
Advantages of polypropylene woven bag
#1. Heat resistance of polypropylene woven bags:
The heat resistance of polypropylene is stronger than that of polyethylene. Generally, the melting point of polypropylene is about 40% -50% higher than that of polyethylene, about 160-170 ° C, so the product can be sterilized at a temperature above 100 ° C. It does not deform at 150 ° C under the condition of no external force. Similarly, in the field of ordinary packaging bags, polyethylene packaging bags are more suitable for use below 90 ° C, while polypropylene packaging bags can also be used at relatively higher temperatures.#2 Rigidity and tensile strength of polypropylene woven bags:
