Blown Film Machine Essential for Flexible Packaging

For soft packaging manufacturers facing challenges in various aspects, the answer to "why blown film machines are essential" isn't some profound theory—it ultimately lies in the irreplaceable role blown film machines play in shaping film performance, improving production efficiency, and controlling costs. ChaoXin has dedicated itself for years to perfecting this core equipment, making it a growth engine applicable to various production scenarios. In fact, blown film machines are the cornerstone of soft packaging production. They transform polymer resins into seamless, high-strength films through biaxial stretching—without this step, there would be no food packaging, medical packaging, e-commerce courier bags, and so on. Therefore, for buyers, choosing the right blown film machine is not just about purchasing a piece of equipment; it's crucial for ensuring consistent product quality and maintaining a competitive edge in the market.

According to the "Global and China Soft Packaging Industry Deep Analysis Report 2025," the global soft packaging market is expected to exceed $350 billion by 2025, maintaining a stable annual growth rate of approximately 4.5%. Food and beverages account for 54% of the application share, and medical soft packaging has an annual growth rate of up to 11.3%—these two areas have extremely strict requirements for film barrier properties, toughness, and safety, which in turn increases the demands on blown film machines. Taking fresh food packaging as an example, high barrier performance is essential. Films produced by ordinary blown film machines usually cannot meet the requirements for shelf life. However, ChaoXin's multi-layer co-extrusion blown film machines can customize the film structure according to the preservation needs of different food items. The intermediate barrier layer effectively blocks oxygen and water vapor, extending the shelf life of fresh food by one or even two times. It is this targeted solution that helps buyers stand out in a competitive market.

From a production perspective, buyers consistently face two major pain points: how to meet production needs and how to control overall costs. I remember discussing this with a medium-sized packaging factory in Jiangxi. They previously used standard blown film machines, but often encountered problems such as uneven film thickness when producing construction packaging films—resulting in a scrap rate as high as 15%. After switching to a customized blown film machine from ChaoXin, everything changed. ChaoXin's engineers adjusted the screw length-to-diameter ratio and mold runner design based on the high-filler-content raw materials they used, and added a dual-outlet air ring to improve cooling uniformity. The result? The defect rate plummeted to 3%, and daily output increased by 40%. That's the value of customization.

ChaoXin's customization capabilities cover almost all mainstream flexible packaging application scenarios. For SMEs just entering the shopping bag industry, ChaoXin's mini blown film machine is an economical choice. It supports film widths from 200mm to 800mm, is easy to operate, and has low energy consumption. Multiple colors and specifications can be switched with just one button – ideal for small-batch, multi-variety production needs. For large manufacturers exporting to European and American markets, ChaoXin's five-layer co-extrusion blown film machine is a powerful tool for meeting environmental standards. It can produce easily recyclable single-material films using biodegradable materials and is CE and SGS certified, helping them successfully overcome international trade environmental barriers. Even for special scenarios such as processing high-proportion recycled materials, ChaoXin can customize wear-resistant screws and barrel components to address equipment wear caused by impurities in recycled materials.

Today, functional requirements account for 38% of the flexible packaging industry – and this is constantly growing. The era of general-purpose blown film machines is long gone. What buyers truly need is equipment that "understands their production scenarios." ChaoXin's approach is to integrate pre-sales needs assessment, in-sales process customization, and after-sales technical support into a complete service, addressing this pain point. When buyers request "production of 0.01mm thick food packaging film" or "24-hour continuous production of wide-width stretch film," ChaoXin's team begins building a tailor-made solution. This in-depth, production-detail-oriented customization service is ChaoXin's strength. This is why blown film machines can truly become the core driving force of flexible packaging production.
