In the plastics industry, raw material costs are one of the factors that directly affect product prices and a company’s competitiveness. As the market becomes increasingly competitive, with more domestic and international manufacturers, finding ways to optimize raw materials, improve productivity, and control production costs has become an important priority for plastics manufacturers.
In addition to investing in machinery, technology, and process improvements, replacing part of virgin resin with alternative materials is also an effective approach. Among these solutions, filler masterbatch, also known as plastic filler or Taical, is widely used in various fields such as packaging, plastic films, pipes, household products, and many other plastic applications.
What is Filler Masterbatch/Taical?
Filler masterbatch, also known as plastic filler or Taical, is a material made from calcium carbonate (CaCO3), a polymer base, and suitable additives. It is used as a blending material with virgin resin before being processed into finished plastic products.
The primary purpose of filler is to replace part of the virgin resin, thereby reducing raw material costs. Depending on its composition and blending ratio, filler can also help modify certain properties of the polymer base, contributing to improved product characteristics and processability.
During the production of filler masterbatch, CaCO3 powder, the polymer base, and additives are blended and heated to form a homogeneous mixture. After cooling, the material is cut into small pellets and then blended with virgin resin at an appropriate ratio.
The resulting filler pellets can be used in various plastic processing technologies, including injection molding, film blowing, film casting, fiber spinning, and blow molding, to produce plastic products for everyday life and industrial applications.
The use of filler masterbatch not only helps manufacturers optimize raw material costs but also increases the value of CaCO3 mineral resources. In particular, Vietnam has relatively abundant limestone resources, creating favorable conditions for the development and use of this material in the plastics industry.
The proportion of filler and additives varies depending on the polymer base, such as PVC, PP, PE, or PC, as well as the specific requirements of the finished product.

Filler Helps Reduce Costs in Plastic Film and Packaging Production
Plastic films and packaging are among the product groups with high raw material consumption. Filler masterbatch can be used in various types of films, ranging from thin and thick films to packaging films, agricultural films, and textile packaging.
When blended with resin at an appropriate ratio, filler can help improve stiffness and strength while maintaining certain requirements for product color and transparency. More importantly, replacing part of the virgin resin helps reduce the amount of raw material required and, consequently, control production costs more effectively.
PE-based filler is also used in the production of various plastic bags and films. In addition to reducing the amount of virgin resin required, it can help produce films with characteristics such as:
- Good transparency, a glossy, soft, and flexible surface.
- Good water resistance.
- The ability to withstand relatively high temperatures for short periods, depending on the formulation and processing conditions.
In addition to filler, specialized additives can be used in the production of plastic bags and films to meet specific product requirements.
For example, EPI and D2W can be used at suitable ratios to support the degradation of plastic bags under certain conditions. Anti-blocking agents help prevent plastic film layers from sticking together, while UV stabilizers help reduce the effects of ultraviolet radiation, limiting aging and color fading.
Filler in the Production of Ceiling Panels, Window Frames, and Plastic Doors
Filler is used in various formulations for products made from rigid PVC, including ceiling panels, window frames, and plastic doors.
Adding filler masterbatch at an appropriate ratio can contribute to improving the stiffness and strength of the products. It can also help create a relatively smooth and glossy surface with uniform color, low dust adhesion, and easier cleaning during use.
Filler in PVC Pipe and Plastic Fitting Production
In the production of rigid PVC pipes and plastic fittings, filler is used to optimize the material formulation and control production costs.
When properly selected and blended at an appropriate ratio, filler can contribute to products with good stiffness, suitable pressure resistance, and a relatively glossy surface. Optimizing the material formulation can also help shorten processing time, increase productivity, and reduce costs.
PVC pipes are widely used in various applications, from agricultural irrigation and water supply and drainage systems to electrical conduit and construction projects.
PVC-Based Filler in Wire and Cable Production
When combined with PVC and suitable additives, filler can be used in the production of electrical wires and cables.
After being uniformly blended using specialized mixing equipment, the material is fed into an extruder to produce pellets. These pellets are then used to manufacture insulation layers or cable sheaths with different operating temperature requirements, such as 70°C, 90°C, or 105°C, depending on the specifications of each product.
After pelletizing, the material continues through further processing stages to produce electrical wires and cables with copper, aluminum, or other suitable conductive cores.

Filler Masterbatch in Molding, Injection Molding, and Other Plastic Products
In addition to the applications mentioned above, filler masterbatch is also used in various plastic processing methods such as blow molding and injection molding.
In blow molding, filler can be blended with the polymer base to produce bottles, containers, and other plastic packaging products. The appropriate material formulation helps control product weight and optimize production costs.
In injection molding, filler is used to manufacture a wide range of products, including components, parts, equipment, household products, and plastic components for the automotive industry.
The filler content should be adjusted based on the polymer base, mechanical requirements, appearance, and specific characteristics of each product to ensure effective processing.
The Trend Toward Using Plastic Compounds in Manufacturing
Along with the development of the plastics industry, methods of blending filler with other materials have also continued to improve. Instead of adding individual additives or fillers directly to the resin during production, many manufacturers are choosing to use technical plastic compounds, or compounds.
Compound pellets typically consist of a polymer base, filler masterbatch, additives, and modifiers blended at predetermined ratios. Since the components have already been relatively uniformly dispersed, the processing stage can be more convenient and stable.
Using compounds helps minimize uneven distribution of material components and supports greater consistency in finished products. In addition, pre-compounded materials can reduce material preparation steps at the factory, keep production equipment cleaner, and make operation more convenient.
Filler – A Solution to Help Businesses Improve Competitiveness
As raw material prices and competition in the plastics market continue to increase, filler masterbatch offers an effective approach to optimizing production formulations.
Replacing part of virgin resin with suitable filler can help businesses reduce raw material costs while supporting improvements in certain product properties and processing efficiency.
From packaging and plastic films to PVC pipes, household products, electrical cables, and injection-molded components, filler masterbatch can meet a wide range of manufacturing requirements. However, to achieve the best results, businesses need to select filler based on the polymer base, processing technology, blending ratio, and specific requirements of the finished product.
With its diverse applications and potential for cost optimization, filler masterbatch is becoming an important material solution that helps plastics manufacturers improve production efficiency and strengthen their competitiveness in the market.
