1. Core Dimensions for Selecting Stretch Film Machines for Small Factories‌

By 2025, the global market size for small and medium-sized stretch film making machine will reach 2.8 billion yuan, with an annual growth rate of 12.7%. For small factories with a production capacity of less than 5 tonnes per day, the selection should focus on three key dimensions:

Space Efficiency‌: The equipment footprint should be less than 15 square metres, and the height of column-type machines must be compatible with a 4-metre ceiling height in the factory.
Energy consumption control: Servo motor models can reduce energy consumption per ton of film by 35% compared to traditional equipment.
Raw material compatibility: LLDPE/PP co-extruded film requires a dual extrusion die head.
Challenges: When connecting to a stretch film rewinding machine, synchronisation accuracy errors must be controlled within ±0.5%, otherwise it may cause the film roll to become loose.

‌Technical Analysis of Mainstream Models in Categories II and III‌

1. Intelligent Servo Type: Wintech ‌

Core Advantages:
Synchronous motor energy consumption is only 1.8 kWh/kg of film, achieving a 42% energy savings compared to traditional models
Modular design supports switching film width (300-500 mm) within 5 minutes
Intelligent tension control reduces film breakage rate to 0.3 times per tonne (industry average: 1.2 times)

Suitable Scenarios:

Daily stable production capacity of 2–4 tonnes
Compatible with eco-friendly packaging production lines where recycled material ratio ≤30%
Price Range: £16,800–£19,800 (including IoT kit)

2. Economic Hydraulic Type: Huarui HR-F280

Cost control:

Base model price as low as RMB 65,000, occupying 8.2 square metres
Hydraulic system maintenance cost < RMB 30 per tonne of film

Technical limitations:

Film thickness uniformity deviation ±8% (servo model ±3%)
Roll change downtime ≥ 12 minutes

‌3. Modular production line: Xinda Integrated System

Expansion capability:

Reserved interface for cast film machine, supporting direct raw material supply
Can be equipped with a scrap material recovery module directly connected to a plastic granulator

Application scenarios:

Growing factories planning to expand to 8 tonnes/day production capacity
Flexible production requirements for multiple types of film products

III. Key parameter comparison and investment model

Machine type/brand	Drive method	Production capacity (kg/h)	Energy consumption per tonne	Film thickness accuracy	Roll change time	Price (ten thousand yuan)
Wintech	Servo motor	90-120	1.8 kWh	±3%	6 min	16.8-19.8
HuaRui HR-F280	Hydraulic	45-65	2.9 kWh	±8%	12 min	6.5–7.2
Indian Pune P55	Gear drive	30–40	3.5 kWh	±12%	18 min	3.8–4.5
Xinda XD-300	Hybrid	70-100	2.3kWh	±5%	8min	22-26

Return on Investment Calculation‌: Although Wintech models have a higher initial cost, based on an annual production of 800 tonnes:

Annual electricity cost savings: ‌￥88,000‌ [(2.9-1.8) kWh/kg × 800 tonnes × ￥1/kWh]
Reduced waste film losses: ‌￥36,000‌ (film breakage rate reduced by 0.9 times/tonne × 800 tonnes × ￥50/time)
‌Payback period of only 14 months‌

‌IV. Golden Rules for Selecting Small Factories‌

1. Production Capacity Matching Principle‌

Basic model‌: <1 ton/day, select a gear transmission model priced at 40,000-80,000 yuan
Advanced model‌: 1-3 tons/day, prioritise servo models
Expanded model‌: Reserve 30% production capacity to meet peak season demand

‌2. Efficiency Improvement and Cost Reduction Pathways‌

Recycled Material Application‌:

Install a melt filter to process recycled materials with up to 15% impurity content
Integrate with a plastic recycling pelletizer to achieve closed-loop utilisation of scrap material

Smart Maintenance‌:

A remote diagnostic system reduces downtime by 60%
Historical process parameter database to shorten new product commissioning cycles

‌3. Compliance Upgrade Strategy‌

VOC emissions must be ≤35 mg/m³ (new national standard by 2025)
Noise control ≤78 dB(A) to avoid noise complaints

‌5. In-depth analysis of Wintech's technological advantages‌

1. Energy-saving patented technology‌

Electromagnetic induction heating: Heating speed is 40% faster than resistance heating, with a thermal efficiency of 92%
Energy feedback system: Energy recovery rate during braking ≥35%

‌2. Intelligent production line coordination‌

Shared formula database with the cast film extrusion production line, reducing switchover time by 70%
Real-time adjustment of tension in the cling film rewinding machine, with film roll hardness deviation <5%
