You’ve seen them as containers of fertilizers, animal feed, fruits, vegetables, produce, and many other products. Woven polypropylene bags, sometimes called PP bags, are versatile items. Because of their handiness and durability, they are often the best choice for practical functions.
If you’re pursuing certain projects, they make a fantastic choice. Polypropylene bags are great for a variety of purposes. They can be used for packaging and storage, or transporting and even sandbags for flood control.
But before making a decision, you would want to learn everything there is about woven polypropylene. Knowing the basics and know-how of this material can help you plan your project and save a great deal of money.
What Are Woven Polypropylene Bags?
Polypropylene bags are made of a tough, durable thermoplastic called polypropylene (PP). This material is often manufacturers’ preferred option for packaging products. It is highly tear-resistant and does well in extreme temperatures. Aside from daily necessities, PP is also used in the healthcare industry as tools and gear.
Woven PP bags are made of this material. Very thin strips of polypropylene are sewn tightly shut in two opposite directions, which is how woven PP bags are constructed. They adopt all the qualities of polypropylene.
That’s why PP sacks are often the best choices to store agricultural products such as soil, fertilizer, and produce. Their resistance to extreme conditions makes them appropriate even for difficult projects. This makes woven polypropylene a top choice for other industries that are demanding durable storage bags. Aside from its agricultural purposes, PP bags are also used in construction and transportation. They can even be placed in water-filled structures as sandbags to help regulate flooding and overflowing.
Aesthetics-wise, PP bags look practical and economical but are also customizable, which makes it a great bet for businesses who want to use them for branding and packaging at the same time.
Different Names Used for Woven Polypropylene Bags“Polypropylene” may not be the simplest word out there, but you can remember it in other ways. The next time you go to a supplier, you can use these easier words to remember:
- PP bags
- Woven poly bags
- Woven PP bags
- Poly sacks
- PP sacks
Make sure to not just shorten the name to “poly bags,” as this can be confused with polyethylene. While PP bags do count as poly bags, polyethylene is a different material altogether. If you must, add “woven” before the phrase.
You can also name what poly woven bags are used for: woven sacks, rice bags, sandbags, and the like. Of course, not all of these bags are made of the same material, so you should at least remember polypropylene’s short, easy nickname: PP.
Properties of Woven Polypropylene Bags
Woven PP sacks are a popular choice in many industries. The plastic itself is used in manufacturing, the medical industry, and even the military sector. Woven PP has remarkable qualities, widely utilized for its convenience. Here are the many qualities of polypropylene bags that make them stand out in terms of usability.
Durability and Resistance to Wear and Tear
When it comes to storing or transporting difficult items, such as sand or gravel, polypropylene is a great solution. As a matter of fact any item that is bulkier and requires tear-resistant containers such as produce, soil, and grovel would fare well in PP bags. PP bags are also great for agricultural storage as they provide protection against bugs and pests.
Because of this, woven polypropylene bags are far superior choices to paper bags or polyethylene bags. Woven PP bags can also withstand extreme temperatures. They stay intact in higher heat or colder conditions, unlike most types of plastics which easily melt or disintegrate.
One of the best things about woven polypropylene is that you can tailor them according to your needs. You can add a label, a logo, or even illustrations to your fabric. Designs can be printed through a machine, or if you’re dealing with less bulk, paint is the way to go.
This is especially helpful if you’re shipping out products from your business. Having customized, memorable packaging can help you grow your business organically.
Storing or shipping produce or anything that needs to keep its moisture? Woven PP bags would come in handy. The material is sewn not too loose enough to leak and not too tight to become inflexible, making it ideal for storage.
Woven poly bags are optimal for fruit and vegetable storage, as they help keep the produce fresh. These bags also hold soil and fertilizer well as they do not drain out softness and moisture.
While they can have strong substances as components, PP bags are non-toxic and considered eco-friendly. This is because they are reusable, which means you consume less waste. They are also the type of plastic that will not melt so quickly. And since they have high levels of fatigue resistance, they can be used many times and for many functions.
Because these bags can be laminated, you can wash off excess product or dirt without any trouble. This extra film layer can add more protection, allowing it to feel good as new despite multiple uses.
