When it comes to securing goods for transport or storage, PE packing film is an industry standard. But with various types of films and the complex machinery used to produce them, knowing exactly what your production line needs can be a challenge. Whether you are a packaging manufacturer looking to upgrade your equipment or a logistics manager sourcing materials, understanding the nuances of Polyethylene (PE) film technology is crucial for efficiency and cost-control.
This guide answers the most pressing questions about PE packing film and the advanced machinery required to produce it, highlighting industry-leading solutions from experts like Guangdong Xinhuida Machinery Technology Group Co.,Ltd.
Polyethylene (PE) packing film is a thin, plastic material used primarily for wrapping products to keep them secure and protected. It is renowned for its elasticity, allowing it to stretch and cling tightly around items, making it ideal for palletizing goods.
The material is essential because it offers superior protection against dust, moisture, and tamper attempts. Its versatility allows it to be used in various industries, from food and beverage to construction and industrial logistics. The primary benefit lies in its ability to stabilize heavy loads during transport, preventing damage and reducing product loss.
There are different variations of PE film, including:
Stretch Film: Highly elastic, used for wrapping pallets.
Cling Film: Thinner, often used for food packaging (like PE cling film).
Silage Film: UV-protected, used in agriculture to wrap bales.

A PE packing film machine creates film through a process called cast extrusion or blown extrusion. In the context of high-speed industrial production, cast film extrusion is widely preferred for its speed and clarity.
Here is the general workflow of a cast stretch film machine:
Feeding: Plastic granules (LLDPE, LDPE, etc.) are fed into the machine's hopper.
Melting and Extrusion: The granules are heated and melted inside an extruder screw, then forced through a flat die.
Cooling: The molten plastic forms a thin sheet that is immediately cooled on a chill roll (casting).
Thickness Control: Sensors ensure the film maintains a uniform thickness (e.g., 8 to 50 microns).
Winding: The finished film is wound onto rolls (jumbo rolls or hand rolls).
Advanced machines, such as those manufactured by Guangdong Xinhuida Machinery Technology Group Co.,Ltd., incorporate automatic features like paper core loading, air shaft inflation, and finished roll unloading to maximize output (up to 18T/day on specific models).
When selecting a machine, specifications dictate your production capacity. Below is a comparison of different machine capacities based on standard industry models.
Feature | 1000mm High-Speed Line | 1500mm Automatic Extruder | 2000mm High-Speed Co-extrusion |
|---|---|---|---|
Film Width | 1000mm | 1500mm | 2000mm |
Typical Output | Medium Volume | High Volume | Ultra-High Volume |
Film Layers | Typically 3-layer | 3 to 5-layer | 3 to 5-layer (or more) |
Roll Application | Hand & Machine Use | Hand, Machine & Jumbo Rolls | Jumbo & Industrial Rolls |
Ideal For | SME Manufacturers | Large Scale Converters | High-Capacity Industrial Plants |
Note: Specific outputs vary by model. For example, XHD models like the XHD-55/80/55-1250 are optimized for 1000mm width, while the XHD-80/120/80-2400 handles massive 2000mm outputs.
The choice largely depends on your target market and production volume goals.
1000mm Machines: These are excellent entry-level or mid-tier machines. They are perfect for producing standard hand-wrap rolls (2-5kg) and smaller machine-wrap rolls. If you are supplying local businesses or smaller logistics centers, this width is versatile and cost-effective.
1500mm Machines: This size offers a "sweet spot" for many manufacturers. A machine like the Automatic 1500mm Cast Jumbo Roll Stretch Film Machine can produce jumbo rolls (50kg) efficiently. It is robust enough to serve export markets where high-volume consistency is required.
2000mm Machines: These are heavy-duty beasts designed for maximum efficiency. If your facility needs to churn out 18+ tons per day or requires wide agricultural films (like silage film), a 2000mm co-extrusion line is necessary. These machines often feature 5-layer co-extrusion for superior film properties (puncture resistance and stretchability).

While the extrusion machine creates the film, the plastic film rewinder is critical for converting huge "jumbo rolls" into smaller, usable products.
A 50kg jumbo roll cannot be used by a warehouse worker wrapping a pallet by hand. The rewinder takes that massive roll and rewinds it into smaller, lighter rolls (e.g., 500 meters or 2kg rolls) that are sold to end-users.
Benefits of a high-quality rewinder:
Speed: Machines like the XHD-500-A operate at speeds up to 1200m/min.
Quality Control: It ensures the tension is correct so the final roll looks professional and unwinds smoothly.
Flexibility: Some machines, like slitter-rewinders, can cut a wide roll into several narrower rolls simultaneously.
Feature | Automatic Rewinder | Slitter & Rewinder |
|---|---|---|
Primary Function | Rewinding jumbo rolls to hand rolls | Cutting wide rolls into narrow strips |
Speed | Very High (approx. 1200m/min) | High |
Typical Use | Mass production of standard rolls | Custom sizes (e.g., narrow banding film) |
Example Model | XHD-500-A | XHD-500-S |
Founded in 2006, Guangdong Xinhuida Machinery Technology Group Co.,Ltd. has established itself as a major manufacturer in the intelligent equipment industry. With over 20 years of experience, they specialize in cast stretch film machines and related equipment.
Their reputation is built on innovation and scale:
Experience: They have manufactured over 8,000 sets of stretch film machines.
Global Reach: Their machinery is exported to over 100 countries.
R&D: They hold 100+ patents and maintain CE and ISO9001:2015 certifications.
Facility: Operations are based in a modern 60,000 SQM factory in Dongguan City, Guangdong.
Xinhuida distinguishes itself not just by selling machines, but by offering complete solutions—from granulation (recycling waste plastic) to extrusion and rewinding.
Yes, but it requires specific machinery designed for dual capability. Standard stretch film machines are optimized for thin packing films. However, agricultural silage film requires different properties, specifically UV protection and higher puncture resistance to protect crops outdoors.
Innovations like the Dual-Function Stretch & Silage Film Extrusion Line allow manufacturers to toggle between these production modes. This versatility is a massive advantage for manufacturers looking to serve both the logistics (packing) and agricultural sectors without investing in two separate production lines.
In the competitive world of plastic film production, labor costs and downtime are profit killers. Automation addresses both.
Reduced Labor: Automatic paper core loading and roll unloading mean one operator can manage multiple lines.
Consistency: Automated thickness control reduces material waste. Using less plastic to achieve the same strength saves money on raw materials (LLDPE).
Safety: Automated machinery reduces manual handling of heavy rolls, lowering the risk of workplace injuries.
Speed: Automatic roll changing happens without stopping the line, ensuring continuous 24/7 production.

The future lies in sustainability and efficiency. The market is moving toward thinner films that offer the same strength (down-gauging) to reduce plastic usage.
To achieve this, manufacturers need high-precision machinery capable of multi-layer co-extrusion. Machines that can integrate recycled materials (via units like the PE Granulator) back into the production line are also becoming essential as the world moves toward a circular economy.
Whether you need a high-speed rewinder or a heavy-duty 2000mm extrusion line, partnering with an experienced manufacturer like Guangdong Xinhuida Machinery Technology Group Co.,Ltd. ensures you have the technology to stay competitive in this evolving market.
