Yes, a standard PE foam net machine is inherently designed to produce both tubular nets and sleeve nets, and in fact these two formats are essentially the same product at different stages of the same extrusion process. Understanding how a PE foam net machine achieves this dual capability is important for operators who want to maximize production flexibility without purchasing separate equipment.
At its core, a PE foam net machine extrudes molten LDPE mixed with a foaming agent through a specially designed annular die. The die creates a continuous tubular foam mesh that emerges as a hollow cylinder. This raw tubular output is the foundation for both end products. If the operator simply cuts the continuous tube into fixed lengths and seals one end, the result is a sleeve net - an open-ended pouch that slips over fruit like apples, pears, or citrus. If both ends remain open and the tube is wound onto a roll, it functions as a continuous tubular net that customers cut to their desired length.
The key component enabling this flexibility is the die head and sizing system of the PE foam net machine. By adjusting the die gap, air pressure inside the bubble, and the cooling ring airflow, the same machine can produce tubular nets ranging from 30 mm to over 200 mm in diameter. For sleeve nets, a servo-driven rotary cutter and a hot-sealing station are added downstream. The cutter chops the tube to preset lengths, and the sealer welds one end shut, creating the familiar fruit sleeve. Many modern PE foam net machine models come with a programmable controller that stores recipes for both formats, allowing operators to switch between tubular roll production and sleeve production in minutes.
Material consumption and throughput differ slightly between the two modes. When producing continuous tubular nets for winding, the PE foam net machine runs at maximum linear speed because there is no intermittent cutting and sealing cycle. For sleeve nets, the machine must pause briefly during each cut-and-seal operation, reducing overall output by roughly 10–15%. However, the value-added sleeve product commands a higher market price, offsetting the slower speed.
It is worth noting that some entry-level PE foam net machine models may lack the integrated cutter and sealer required for finished sleeves. In such cases, the machine still produces tubular netting, but the operator must perform cutting and sealing manually or on a separate post-processing line. Therefore, when purchasing a PE foam net machine, buyers should specify whether they need the fully automatic sleeve-making option or plan to handle finishing offline.
Maintenance considerations also vary. Tubular roll production puts continuous stress on the winder and tension control system, while sleeve production increases wear on the cutter blade and sealing jaws. Regular inspection of these components ensures the PE foam net machine maintains consistent quality across both formats.
In conclusion, a properly equipped PE foam net machine supports both tubular and sleeve nets with minimal modification. The same extrusion line, die head, and cooling system serve both purposes; only the downstream handling differs. This dual capability makes the PE foam net machine a versatile investment for fruit packaging operations that need to supply multiple net formats to different customers.
