Open-melt masterbatch: Highly efficient, smooth and anti-sticking. A must-have functional masterbatch for plastic film processing!
During the blow molding and bag-making processes of plastic films, problems such as membrane adhesion, difficulty in layer separation, and difficult opening and closing are common issues that affect the user experience and processing efficiency of the products. The opening masterbatch is specially designed for various polyolefin film products. It selects high-quality smooth opening additives, compatible carrier resins, and functional auxiliary materials for scientific blending. It undergoes precise mixing and high-temperature granulation processes for processing and forming. The masterbatch particles are uniform, have good melt dispersion, and have good compatibility with various film substrates. It does not affect the basic toughness and transparency of the film. It is an important functional auxiliary material for improving the opening performance and optimizing the processing feel in film production.
The core function of the opening masterbatch is to effectively reduce the adhesion force on the surface of the film during bonding, preventing adhesion and sticking phenomena during film winding, storage, and stacking of finished products. This enables the film products to open and close smoothly, making subsequent operations such as bag making, cutting, and packaging more convenient. The addition ratio is reasonable, and there is no need to significantly adjust the original production formula. It has strong machine adaptability, with a uniform plasticization process, and will not cause precipitation, accumulation, or frosting on the surface. It does not affect the printing and composite performance of the film, ensuring the film has a transparent and clean appearance without spots or impurity flaws.
The product has excellent high-temperature resistance and is suitable for high-temperature blow molding processing of films. During the production process, it maintains stable properties and is not prone to decomposition or deterioration, thus not affecting the tensile strength and overall toughness of the film. After being added, the surface smoothness of the film is moderate, with a fine texture and no stickiness. It is not prone to problems such as loss of opening effect or film surface discoloration and deterioration over a long period of storage. Its weather resistance is outstanding. The formula complies with environmental protection standards, has no irritating odor, does not contain harmful substances, and is suitable for various compliance production standards for food packaging, daily use packaging, and industrial protective films.
Suitable for packaging films for express delivery, food preservation films, daily-use plastic bags, agricultural films and various processed plastic films. Compatible with conventional blown film production equipment. Easy to change materials and clean. Smooth production connection. Relying on stable opening effect, good processing adaptability and long-lasting usage performance, the opening masterbatch effectively improves the yield rate of film production, simplifies subsequent processing procedures, optimizes the user experience of the finished products, and enhances the quality and efficiency of film production.
