Introduction: The Woven Packaging Landscape in Indonesia
As an agriculture-driven economy, Indonesia relies heavily on its woven bag industry. PP woven bags are widely used to package rice, grains, fertilizers, and countless other agricultural commodities.
In this competitive market, manufacturers are under constant pressure to produce high-quality bags that withstand harsh conditions during transportation, handling, and storage – all while optimizing production costs.
This is the story of how one leading Indonesian manufacturer faced this challenge and overcame it with Mega Plast’s tailored solution.
Challenges: Weak Bag Strength – A Major Risk for Agricultural Products
Our partner in Indonesia was facing a critical issue: the tenacity of their PP woven bags decreased significantly after adding CaCO3 Filler Masterbatch from their existing supplier.

As a result:
- Finished bags had poor strength and tore easily under load
- They were unsuitable for packaging heavy agricultural products
- Product loss and damage affected customer trust and brand reputation
- Inconsistent quality between batches created production instability and difficulties in controlling output standards
They needed a solution that would not only solve the strength issue but also ensure stability and cost efficiency.
Solution: Superior Quality at Competitive Pricing from Mega Plast
Upon receiving the customer’s inquiry, Mega Plast’s technical team quickly analyzed the situation. With over 21 years of industry experience and deep expertise in PP woven bag applications, we identified the root cause: the formula and quality of the masterbatch they were using.
Mega Plast’s Comprehensive Solution
✅ Specialized Product:
We introduced CaCO3 Filler Masterbatch Grade W262, designed by our R&D experts to enhance the tenacity and durability of PP woven bag yarns.
✅ Advanced Technology:
W262 is produced on state-of-the-art manufacturing lines, ensuring excellent dispersion of calcium carbonate in the polymer matrix. This eliminates weak points along the yarn, resulting in uniform strength across the entire product.
✅ Consistent Quality:
We guarantee batch-to-batch consistency, resolving the variability issue they faced with their previous supplier.
✅ Competitive Pricing:
Most importantly, Mega Plast offered this superior solution at the same price as the low-quality product they had been using.
