Moisture control is an important part of using sodium sulfate filler masterbatch in PE blown film, plastic bags and other extrusion applications.When raw materials absorb excessive moisture, manufacturers may encounter bubbles, pinholes, rough film surfaces, unstable extrusion and inconsistent finished...
PE courier bags and poly mailers are widely used to package clothing, accessories, documents and e-commerce products. With increasing demand for delivery packaging, manufacturers must control raw-material costs while maintaining reliable sealing, puncture resistance and production stability.Sodium sulfate filler masterbatch...
Before purchasing sodium sulfate filler masterbatch in large quantities, plastic manufacturers should conduct a controlled production trial.A sample may appear suitable based on its colour and pellet shape, but its actual performance depends on the resin formulation, processing equipment, film...
Xinfeng Masterbatch is pleased to announce our upcoming participation in Plastex Uzbekistan 2026, the 16th International Exhibition on the Plastics and Polymers Industry.The exhibition will take place from September 22 to 24, 2026, at Uzexpocentre NEC in Tashkent, Uzbekistan. Customers,...
T-shirt bags—also called vest bags, carrier bags or shopping bags—are produced in large quantities and face strong price competition.Manufacturers need to control raw-material costs while maintaining stable film blowing, reliable bottom sealing and sufficient handle strength.Sodium sulfate filler masterbatch may...
LDPE, LLDPE and HDPE all belong to the polyethylene family, but they do not provide identical processing or finished-product properties.A sodium sulfate filler masterbatch that performs well in one PE formulation may require a different dosage or grade in another....
Sodium sulfate filler masterbatch can reduce the formulation cost per kilogram by replacing a controlled portion of plastic resin in suitable applications.However, adding an inorganic filler also changes the density of the formulation. If film thickness, molded-part dimensions and machine...
White spots, visible particles and rough surfaces are common concerns when a new filler masterbatch is introduced into plastic production.These defects may appear in PE blown film, plastic bags or PP injection-molded products. Although the filler masterbatch is often suspected...
Stable film extrusion does not always guarantee successful bag production.A PE film may appear smooth and run steadily on the blown-film machine but develop weak, brittle or inconsistent seals during bag making. This can happen after introducing sodium sulfate filler...
Plastic film and bag manufacturers commonly use two methods to reduce raw-material costs: increasing recycled polyethylene content or adding filler masterbatch.Both approaches may reduce the consumption of virgin resin, but they affect the formulation differently.Recycled PE is still polymer material...
