What Is Polypropylene and Why Is It Used in Woven Poly Bulk Bags?

Agricultural businesses use bulk bags for dry goods because they are durable and flexible. Plus, bulk bags are an affordable way to store and transport goods. Often bulk bags are constructed of woven polypropylene material. Learn more about polypropylene and why it is used in woven poly bulk bags.

Key Takeaways

Polypropylene is a durable, versatile thermoplastic used in woven poly bulk bags.
It is resistant to water, mold, chemicals, and UV exposure, making it ideal for agricultural storage.
Polypropylene bulk bags are lightweight, flexible, and cost-effective.
Customization options allow businesses to enhance branding and improve functionality.
The material is eco-friendly, recyclable, and contributes to long-term sustainability.

What is Polypropylene?

The chemical designation for polypropylene is C3H6, which refers to a type of thermoplastic polymer resin. This plastic is used in various applications, including structure and fiber-type plastic uses. It is commonly used for household, industrial, and commercial purposes, including woven poly bulk bags for agriculture. The use of polypropylene dates back to the mid-1950s when it was first polymerized by chemists Karl Rehn and Giulio Natta.

Versatile and Durable

The global market for polypropylene is over 45 million tons. This plastic is versatile and durable, which is why it is used in so many applications around the world. Many products contain polypropylene including toys, carpets, stationery, speakers, laboratory equipment, reusable containers, automobile products, and agricultural bulk bags. Polypropylene is a popular choice because it has a high melting point so it works well for food containers used in ovens and microwaves. Plus, it can be customized, much like woven poly bulk bags.

Waterproof Bulk Packaging

Woven poly bulk bags are popular for dry goods. It is imperative to ensure dry items remain that way so they are safe to distribute and sell. And it is inevitable they will face weather and inclement weather conditions along the way. Fortunately, polypropylene does not absorb water.

No Mold

If one item gets moldy, everything around also develops mold. This can ruin an entire shipment of dry goods and become costly for agricultural businesses. Polypropylene does not mold. And it will not deteriorate due to bacteria or other elements, making it an ideal choice for bulk bags.

New Benefits of Polypropylene in Bulk Bags

Check out some of the benefits below:

Resistant to Chemicals and Contaminants

Polypropylene is highly resistant to chemicals, which helps protect the contents of bulk bags from contamination. This makes it ideal for agricultural, industrial, and food-related applications. The non-reactive nature of polypropylene ensures that stored products remain pure and unaffected by external elements.

UV Resistant for Outdoor Storage

Many agricultural businesses need to store bulk bags outdoors. Polypropylene can be treated with UV stabilizers to enhance its resistance to sunlight, reducing degradation from prolonged exposure. This feature helps maintain the strength and durability of bulk bags, ensuring long-term usability.

Eco-Friendly and Recyclable

Sustainability is a growing concern in the packaging industry. Fortunately, polypropylene is recyclable, reducing environmental impact. Many businesses are now reusing and repurposing bulk bags to minimize waste. Additionally, advancements in biodegradable polypropylene are being explored to make packaging even more eco-friendly.

Customization for Branding and Functionality

Beyond its structural advantages, polypropylene bulk bags can be customized with various coatings, colors, and printing options. Companies can add laminated layers for additional protection against moisture while branding elements such as logos, product details, and handling instructions can be printed directly onto the bags. This enhances brand recognition and improves efficiency in shipping and storage.

Cost-Effective Long-Term Solution

With rising costs in packaging materials, polypropylene remains a cost-effective choice. Its durability allows for multiple reuses, reducing the need for frequent replacements. Businesses benefit from lower packaging expenses while maintaining the safety and integrity of their stored goods.

Lightweight and Flexible

Polypropylene is sturdy and not likely to shatter. It is also a flexible material that can be turned into a fiber-like texture to create woven bulk bags. Because of the nature of the material, these bags are light and do not add extra weight to the load. Plus, they can be folded after use to take up little room in a storage area. And poly bulk bags can be reused, making them a solid investment.

Inexpensive Material

Agricultural companies face many challenges to remain profitable in the modern business world. Polypropylene is affordable, so the cost of bulk bags won’t break the bank. And that means these companies can be more profitable by reducing losses and spending less to keep their dry goods safe. In addition, it does not contain BPA, which is considered unsafe for food packaging. So this plastic is a viable choice for the bulk bags used to transport all types of dry food products including rice, beans, and dog food.

Printed Bulk Bags

Finally, woven poly bulk bags come in a variety of sizes and can be printed to indicate the contents of the bag. Or printed bulk bags may feature the name of the company and its contact info to act as a mobile advertisement. Everywhere the bulk bags go, people will see the name of the business.

What is the Difference Between Micron and Gauge of Stretch Film?

When selecting a stretch film for packaging and shipping, you may notice that thickness is measured in either microns or gauge. Both terms describe the same characteristic—the film’s thickness—but they are used in different parts of the world. Micron is the standard unit in the metric system, commonly used internationally, while gauge is the preferred measurement in the United States. Understanding how these units compare and convert can help ensure you choose the right stretch film for your specific application.

Key Takeaways

Micron and gauge are both units of measurement used to determine the thickness of stretch film.
Micron is the standard international unit, while gauge is more commonly used in the U.S.
Thicker stretch films offer greater durability, but the right choice depends on your packaging needs.
Understanding these measurements ensures you select the best stretch film for your application.

Understanding Stretch Film Thickness Measurements

Stretch film plays a crucial role in securing products for storage and transportation. However, when selecting the right stretch film, you may come across two different thickness measurements: micron and gauge. While both measure the film’s thickness, they are used in different regions and industries, which can sometimes cause confusion.

By understanding the difference between these two units, businesses can make more informed purchasing decisions to ensure optimal load containment, cost-efficiency, and durability.

What is Micron in Stretch Film?

Micron (μm) is a unit of measurement in the metric system, widely used in Europe and other international markets. One micron is equivalent to one-thousandth of a millimeter (0.001 mm). Stretch films measured in microns typically range from 12 to 30 microns, with thicker films offering better puncture resistance and holding strength.

Here’s a general guide to micron-based stretch films:

12-17 microns – Light-duty applications, ideal for small or lightweight packages.
17-23 microns – Medium-duty applications, commonly used for standard pallet wrapping.
23-30 microns – Heavy-duty applications, providing extra durability for securing sharp or heavy loads.

What is Gauge in Stretch Film?

Gauge is a unit of measurement primarily used in the U.S. packaging industry. The term originates from a time when film thickness was measured using different tools and methods. One gauge equals 0.254 microns, meaning that the higher the gauge number, the thicker the film.

Here’s a common gauge-to-micron conversion:

40 gauge = 10 microns (light-duty)
60 gauge = 15 microns (light-duty)
80 gauge = 20 microns (medium-duty, standard industry use)
100 gauge = 25 microns (heavy-duty)
120 gauge = 30 microns (extra-heavy-duty)

Micron vs. Gauge: Which One Should You Use?

The choice between micron and gauge depends on your industry, location, and specific packaging needs. If you operate in the U.S., gauge is the more commonly recognized measurement, whereas international companies and manufacturers often rely on microns.

When selecting stretch film, consider the following factors:

Load Stability – Heavier or irregularly shaped loads require a thicker film, usually in the 23-30 micron or 100-120 gauge range.
Cost-Efficiency – Thicker films offer better durability, but a thinner film with higher stretch capacity can be more cost-effective for lighter applications.
Application Method – Hand stretch film is often available in lower gauge/micron thicknesses, while machine-applied films are typically thicker for enhanced performance.

Choosing the Right Stretch Film

Understanding the difference between micron and gauge ensures that you select the most effective stretch film for your packaging needs. Whether you’re wrapping pallets for shipping or securing products for storage, choosing the correct thickness helps improve load stability, minimize waste, and reduce overall costs.

Is BOPP Plastic Recyclable?

Is BOPP recyclable? Is BOPP biodegradable? Many people ask, “Is polypropylene eco-friendly?” BOPP plastic bags are environmentally friendly even though they are not biodegradable. They can be reused and recycled—they can be recycled many times over while still maintaining their value. Eliminating waste and recycling boosts revenue and decreases your company’s carbon footprint. This is why biaxially oriented polypropylene recycling is a massive benefit of using BOPP plastic bags.

The Environmental Working Group rates polypropylene as a low to moderate hazard. The dope-dyed method of printing bags does not require water and thus requires no wastewater disposal. This is a cost saver for your business and better for the environment.

BOPP Plastic is Cost-Effective

BOPP woven sacks are easy to obtain at a relatively low cost. Their integrity and strength keep your product safe and reduce loss due to seepage. Your product will have a longer shelf life as BOPP bags keep moisture out and protect from sun damage. BOPP plastics weigh less than paper bags as they use fewer layers. Weighing less means more affordable shipping costs. Using fewer layers than paper bags, BOPP options weigh less, saving weight and shipping costs.

How To Choose The Right Bag For Your Packaging Needs

Choosing the right bag for your packaging depends on your product and goals. BOPP bags are a great choice if you need strong, durable bags for heavy items. Think about your product’s weight, how it will be stored or shipped, and the type of branding you need. Matching the bag’s features to your needs ensures your packaging is functional and attractive.
