The sudden advancement in the use of synthetic polymers in the past few years has paved the way for new and exciting materials to be discovered and used for different applications. An example of this would be polypropylene. This innovative material is especially useful for packaging. Here we will discuss everything you need to know about woven polypropylene bags and how they are made. Find out more information about how polypropylene bags are made, and their manufacturing process below.
Our bags can withhold weight from between five kilograms to two thousand kilograms. Trunel Bags is a leading supplier of tree bags. We also offer one ton copper ore transportation bags for sale as well as plastic sheeting.
This process starts with tape extrusion. This step is the first and most important one in creating a woven bag because it directly impacts the final quality of the bag.
The mixture is heated to a certain temperature for plasticization in the extrusion step, then pushed onto a flat sheet and cooled in a water tank. After the first cooling, the flat sheet is divided with a precision cutter. After splitting, the flat tape is heated, stretched, and cooled several times to achieve the required linear tensile strength.
Of course, we know that the most important step in this process is the weaving, after all that’s where the name of the product comes from.
When it comes to creating woven polypropylene, you need to take some strips of the material and weaving them together. Weaving polypropylene threads are usually done in two directions called the warp and weft. This weaving technique requires that the material be woven in a tight circular pattern. Once the threads have been woven, the bottom of the bag is sewn to prevent any items from falling out of the bag. This weaving method gives these bags their name, which makes these bags so strong and durable.
The popularity of polypropylene bags seems to be increasing, especially in the agricultural and food packaging industries. We see woven bags being used as a packing for fruits, vegetables, maize, and even rice.
Besides the fact that these bags are made from eco-friendly materials, there are so many other reasons why you should choose to use them.
