Agricultural blown film machines play a crucial role in modern farming technology, providing versatile solutions for various agricultural applications. From mulching and greenhouse covering to silage wrapping, these specialized machines ensure efficient and cost-effective agricultural film production tailored to the needs of the agricultural sector. In this comprehensive blog, we will explore the key features, materials, working principles, benefits, advancements, and tips for choosing the right agricultural blown film machine.

Blown Film Extrusion Lines are the powerhouses behind various thin plastic films used in packaging, agriculture, construction, and more. Understanding their parts is crucial for optimal production, consistent quality, and efficient troubleshooting. Let's explore the 12 key components involved in this fascinating process.

With the continuous development and technological advancement of the packaging industry, film manufacturing processes are also constantly evolving to cope with the increasingfunctional and environmentally friendly demands for flexiblepackaging materials in the downstream market.

Explore LDPE film production through the sophisticated features of LDPE Blown Film Extrusion Machines. Specifically designed for thin plastic films and bags, these machines transform LDPE resin into a blown tube, which is stretched, cooled, and refined through precision slitting and winding. LDPE resin, known for unmatched flexibility, strength, and moisture barrier properties, takes center stage in manufacturing plastic bags and packaging films, outshining alternatives like HDPE and LLDPE. LDPE films set a new standard with enhanced clarity and gloss, revolutionizing plastic film production.

In the race to stay ultra-competitive in today's dynamic food industry marketplace, it is important to invest in the right technology that marries functionality, durability, and quality. Enter the 5/7/9-layer blown film extrusion lines — the epitome of cutting-edge technology in the world of film packaging, particularly suited for accommodating a wide range of food packaging applications with their superior barrier properties, strength, and printability.

We have a machine with two sets of extrusion parts and a three-layer co-extrusion die. The surface layer shares one extruder, which we call Layer A, and the other extruder is on the middle layer, which we call Layer B. Therefore, the blown film structure is a three-layer co-extruded film of A, B, and A layers.

The blown film machine is suitable for producing various kinds of high-end packaging films with sound barrier properties, freshness retention, moisture retention, freeze resistance, oxygen resistance, and oil resistance. It can be used for the light and heaving packaging of fresh fruits, meat products, pickles, milk, liquid beverages, and medicine.

In order to meet customers’ special requirements for the production process and co-extrude multi-functional plastic films that combine the properties of various materials (such as breathability, waterproofness, insulation, toughness, etc.), we have developed the multi-layer co-extrusion plastic blown film machine after years of research and practical development. Its purpose is to give play to the advantages of different materials and avoid the shortcomings of a single material or a single-layer blown film machine. PLASTAR is committed to providing customers with market-competitive blown film machines.
