Xinfeng Begins Customer Follow-Up After Plastex Uzbekistan 2026

Xinfeng has completed its participation in Plastex Uzbekistan 2026, held from September 22 to 24 at Uzexpocentre NEC in Tashkent.
We sincerely thank the plastics manufacturers, distributors and industry professionals who communicated with our team during the exhibition.
Our next step is to continue these conversations through product recommendations, sample preparation and application-specific production trials.
The official event was the 16th International Exhibition on the Plastics and Polymers Industry. According to the organiser, the exhibition brought together 255 companies from countries including China, Uzbekistan, Germany, India, Italy, South Korea, Türkiye and the United Arab Emirates.

Introducing Xinfeng’s Masterbatch Solutions
At Plastex Uzbekistan 2026, Xinfeng focused on functional additives for plastic-processing manufacturers.
Our primary product is sodium sulfate filler masterbatch, which can be tested in selected PE blown-film and PP injection-moulding applications.
Potential applications include:
T-shirt bags
Shopping bags
Garbage bags
Courier and mailing bags
General packaging film
Selected PP household products
Plastic hangers
Storage containers
General injection-moulded parts
The purpose of using filler masterbatch is generally to reduce resin consumption and improve production economics while maintaining acceptable processing and finished-product performance.
Because every factory uses different raw materials and equipment, the product must be evaluated under actual production conditions.
From Exhibition Discussion to Production Trial
An exhibition meeting is only the beginning of technical cooperation.
To recommend an appropriate masterbatch grade, our team needs to understand the customer’s complete application.
Useful information includes:
Main resin type
Virgin and recycled material ratio
Finished-product application
Film thickness or product wall thickness
Current additive formulation
Required transparency
Colour requirements
Production equipment
Current processing problems
Target cost reduction
Based on this information, Xinfeng can prepare a more relevant sample and suggest a conservative starting dosage for production testing.
Support for PE Blown-Film Manufacturers
For PE blown-film applications, the evaluation should cover more than film appearance.
Important trial indicators include:
Pellet dispersion
Film-bubble stability
Extruder pressure
Production output
Film thickness
Transparency
White spots
Tensile strength
Tear resistance
Heat-sealing strength
For finished plastic bags, handle strength, bottom sealing and realistic load performance should also be checked.
The highest possible addition ratio is not necessarily the most economical. Excessive filler may increase rejected film or reduce bag performance, offsetting the savings in resin cost.
Support for PP Injection Moulding
For selected PP injection-moulding products, customers should evaluate:
Material feeding
Plasticisation
Mould filling
Surface appearance
Colour consistency
Product shrinkage
Warpage
Impact strength
Cycle time
Rejection rate
Products with thin walls, long flow paths, hinges or load-bearing structures require particularly careful testing.
The carrier resin of the masterbatch must also be compatible with the PP formulation.
Moisture and Storage Management
Storage and material handling are important topics when using filler masterbatch.
Material bags should remain sealed and be stored in a clean, dry environment. Opened packaging should be resealed promptly.
If moisture is present, PE film production may experience:
Bubbles
Pinholes
Rough surfaces
Unstable film bubbles
Irregular extrusion pressure
Customers should check every material in the formulation, including recycled resin, colour masterbatch and other additives, before identifying the source of a moisture problem.
Samples for Customer Evaluation
After the exhibition, Xinfeng is available to arrange samples for suitable customers and applications.
A controlled trial should begin with a conservative dosage. The addition level can then be increased gradually while the manufacturer records processing and product-quality results.
Each trial should include:
The original formulation as a control.
Accurate weighing and mixing.
Stable machine settings.
Production observations.
Finished-product testing.
Total cost calculation.
Samples retained for comparison.
This approach helps manufacturers identify a practical balance between cost reduction and product performance.
Calculating Real Manufacturing Savings
The real value of a filler masterbatch should be calculated from the cost per acceptable finished product.
The evaluation should include:
Resin savings
Masterbatch cost
Product weight
Production speed
Energy consumption
Rejection rate
Machine-cleaning frequency
Printing and sealing waste
Customer-quality requirements
A stable formulation with fewer rejected products may be more economical than a formulation using a higher filler percentage.
Cooperation with Central Asian Customers
Plastex Uzbekistan provided an opportunity for plastics-industry companies from Uzbekistan and surrounding markets to communicate directly with raw-material, equipment and technology suppliers.
Following the exhibition, Xinfeng will continue developing relationships with manufacturers and distributors in Central Asia.
We welcome enquiries from companies producing:
PE film and plastic bags
Courier packaging
Household plastic products
PP injection-moulded products
Colour and functional masterbatch
Recycled plastic products
Distributors interested in introducing Xinfeng products to their local markets are also welcome to contact us.
Thank You for Meeting Xinfeng
We appreciate everyone who took the time to learn about Xinfeng and discuss plastic-processing applications with our team during Plastex Uzbekistan 2026.
Customers who requested technical information or samples are encouraged to continue the conversation by sending their formulation and product requirements.
Even if you were unable to meet us at the exhibition, you can still contact Xinfeng for product information, sample evaluation and technical communication.
