Shuangli Plastics Machinery 2026 Shanghai Adsale Exhibition: The Five-layer Co-extrusion Down-blowing Water Cooling Machine Ignited The Audience! The Same Model Is Now Open For Pre-order, And The Exhibition Price Will Continue To Be Available At The Xindu Industrial Park

I. Debut at Shanghai Adsale Exhibition: Five-layer Co-extrusion Blown Film Water-cooling Machine Becomes a "Star Exhibit"

As one of the most influential exhibitions in the global plastics and rubber industry, CHINAPLAS 2026 gathered over 4,000 exhibitors from more than 40 countries and regions. Although it was the first time for Shuangli Plastics Machinery to participate in the exhibition, it achieved a "good start" at its booth on 3F16, thanks to its solid technical foundation and cost-effective positioning.

At the booth, a five-layer co-extrusion down-blow water-cooled film blowing machine was continuously operating, demonstrating the entire process from raw material input to film forming on site. The audience could clearly see that after flowing out of the die head, the film was rapidly cooled by water, instantly forming a finished film roll with high transparency, high stiffness, and a strong surface gloss.

"The film blown by this machine is as transparent as glass!" exclaimed a boss of a flexible packaging factory from Zhejiang at the scene. On the first day of the exhibition, this booth attracted more than 200 professional visitors to stop and chat. The popularity continued for the next three days, with visitors even having to queue up for consultation at one point.

II. The startup demonstration captivated the audience: technical prowess captivated professional buyers

Why can the five-layer co-extrusion down-blow water-cooled film blowing machine become a "hot product"? The technical director of Shuangli Plastics Machinery gave a detailed explanation to the audience at the exhibition:

·Five-layer structure, comprehensive performance upgrade: Compared to traditional three-layer co-extrusion, the five-layer structure allows for optimized design of the barrier layer, adhesive layer, support layer, heat seal layer, and surface layer, enabling the film to achieve a qualitative leap in multiple indicators such as oxygen barrier, water vapor barrier, puncture resistance, heat seal strength, and surface glossiness.

·Down-blowing water cooling process, efficient and energy-saving: The forced circulation water cooling system is adopted, with a cooling efficiency that is over 30% higher than that of air cooling. The transparency and flatness of the film are significantly better than those of conventional models, while the unit energy consumption is reduced by about 20%.

Suitable for high-end packaging field: The five-layer co-extruded film produced by this machine is widely used in demanding scenarios such as frozen food packaging, vacuum packaging, medical sterilization packaging, and high-barrier industrial packaging, where stringent film performance requirements are imposed.

At the exhibition, Shuangli's technical staff also displayed comparative samples of films made with different formulas: under the same thickness, the impact resistance of the five-layer co-extruded film was about 35% higher than that of the three-layer film, and the oxygen transmission rate was reduced by nearly 50%. The data convinced many professional buyers.

III. The exhibition has not yet ended, but the prototype has already been ordered

On the third day of the exhibition, the head of a packaging materials enterprise from Jiangsu Province, after a detailed inspection of the equipment operation, inquiring about technical parameters, and comparing with multiple exhibitors, decided to sign up for the prototype on display on the spot.

"We have investigated five film blowing machine manufacturers, and Shuangli's five-layer down-blowing water-cooled machine meets our requirements in terms of stability, film surface effect, and cost-effectiveness the most," said the customer. "Moreover, the prototype has been running continuously for three days at the exhibition, and its performance has been very stable, which reassures us."

The sales manager of Shuangli Plastics Machinery revealed that during the exhibition, they received over 150 valid inquiries, among which more than 30 customers explicitly expressed their intention to purchase, covering East China, South China, Southwest China, and some Southeast Asian markets.

IV. Exhibition discounts continue: same model is available for pre-order, and factory inspection provides a more intuitive experience

In response to customer demands who were unable to place orders in time during the exhibition, Shuangli Plastics Machinery officially announces: the five-layer co-extrusion down-blow water-cooled film blowing machine of the same model, power, and specifications is now available for pre-order. Customers can directly visit Shuangli Plastics Machinery's factory located in the Xindu Town Industrial Park, Tongcheng, Anhui Province for on-site inspection and testing, and continue to enjoy the preferential purchase price of the prototype displayed at the exhibition.

This means that even if customers miss the Shanghai Yashi Exhibition, they can still acquire this "star model" at the same exhibition discounted price. The factory can showcase a five-layer co-extrusion blown film production line of different specifications on site, and provide a film testing service with supplied materials - customers can bring their own raw materials and start production of film samples on site to intuitively verify the equipment performance.

5. Why choose the five-layer co-extrusion down-blowing water cooling machine from Shuangli Plastics Machinery?

1. The core components, such as the die head and screw, which are independently developed, are all designed and manufactured by Shuangli. After 20 years of technological iteration, the precision of the flow channel and the uniformity of the composite are guaranteed.

2. Three-year extended warranty: Core components (die head, material rod) are provided with a three-year warranty, far exceeding the industry average, reflecting absolute confidence in our own quality.

3. Source factory, leading cost-effectiveness: Shuangli boasts its own factory premises and comprehensive processing capabilities. From turning, milling, planing, welding to complete machine assembly, all processes are carried out in-house, eliminating intermediaries. This ensures that our products are more competitively priced for equivalent configurations.

4. Improve after-sales system: Provide full lifecycle services including installation and debugging, operation training, remote diagnosis, on-site maintenance, etc., to ensure customers can start using the product without worries.

VI. Market response: Amidst the rise in raw material prices, the five-layer co-extrusion machine has become a powerful tool for "cost reduction and efficiency enhancement"

Since 2026, the prices of major plastic raw materials such as polyethylene (PE) have remained high, putting film production enterprises under significant cost pressure. At this time, the value of five-layer co-extrusion down-blowing water-cooled film blowing machines becomes even more prominent:

·Optimizing the formula through a five-layer structure: Expensive functional materials (such as EVOH barrier layer and metallocene toughening layer) can be concentrated on key thin layers, while low-cost fillers can be used for the core layer, effectively reducing raw material costs while ensuring film performance.

·Reduced lamination processes: Traditional high-barrier films often require dry lamination to bond different functional films together, which involves multiple processes, high losses, and high costs. The five-layer co-extrusion molding process eliminates the lamination step, reducing the overall cost by 15%-25%. Many customers who inquired at the exhibition site said, "Raw materials have risen sharply, and we urgently need equipment that can 'save material without compromising quality.' Shuangli's five-layer machine is just what we need."

VII. From "cost-effective" to "high-quality", the brand evolution journey of Shuangli Plastics Machinery

Looking back at the development trajectory of Shuangli Plastics Machinery: starting from the local Tongcheng Plastics Machinery Exhibition, to national exhibitions in Zhengzhou, Chengdu, Wenzhou, and so on, and then to this year's first
