For companies planning to invest in an A4 copy paper production line, the most common questions are: How many tons can be produced per month? What is the cost? What is the profit? This article uses the CHM-A4-2 double rotary knife A4 copy paper production line as an example to analyze capacity, cost, and profit for investor reference.
Note: The following calculations are based on standard operating conditions (70gsm copy paper, average speed 250 m/min, effective production 6.5 hours/day, 27.5 days/month). Actual figures vary with market factors such as base paper price, finished product selling price, electricity, and labor. Equipment purchase, transportation, and installation costs are not included. For actual investment, please refer to the CHM technical agreement and local market conditions.

I. Monthly Capacity Calculation
Basis:
Base paper GSM: 70gsm
Average running speed: 250 m/min
Effective production time: 6.5 hours/day (after deducting roll changes, material preparation, and downtime)
Production days per month: 27.5 days
Ream specification: 500 sheets/ream, ream height 45–55 mm
Capacity estimation:
Per minute: approx. 29.4 kg, approx. 13 reams
Per hour: 1,764 kg, approx. 780 reams
Per day: 11,466 kg, approx. 5,070 reams, approx. 633 boxes (based on 8 reams/box)
Per month: approx. 315 tons, approx. 139,425 reams, approx. 17,428 boxes
One standard A4-2 production line can meet a monthly output of 300–900 tons, depending on production shifts and operator proficiency.


II. Cost Structure
Based on a monthly output of 300 tons:
| Cost Item | Amount (RMB/month) | Notes |
|---|---|---|
| Labor | 18,000 | 2 operators, 1 assistant, 1 manager |
| Base paper | 1,740,000 | 300 tons × 5,800 RMB/ton |
| Wrapping paper | 40,900 | Approx. 0.28–0.30 RMB/sheet × 136,363 reams |
| Cartons | 56,200 | Approx. 3.3 RMB/box × 17,045 boxes |
| Hot melt adhesive | 8,400 | 42 RMB/kg, 1 kg for 1.5 tons |
| Other losses & waste paper recovery offset | approx. -10,000 | Waste paper recovery credit |
| Rent | 42,000 | Machine & space 100 m² + warehouse 1,000 m² + office 100 m² + turnover 200 m², at 30 RMB/m² |
| Electricity | 5,500 | 25 kW/h × 8 h × 27.5 days |
| Total Cost | approx. 1,920,000 | approx. RMB 1.92 million/month |
III. Profit Analysis
Based on 136,363 reams per month:
| Selling Price (RMB/ream) | Monthly Sales (10,000 RMB) | Monthly Gross Profit (10,000 RMB) |
|---|---|---|
| 16 (low domestic) | 218 | approx. 26 |
| 20 (mid-range) | 273 | approx. 81 |
| 23 (high domestic) | 314 | approx. 121 |
Note: The above gross profit does not deduct equipment depreciation, financial expenses, management expenses, etc. Actual net profit will be lower. However, it shows that the A4-2 production line has good profitability under normal operation.
IV. Ways to Increase Profit
Extend production hours: From single shift to double or triple shifts, capacity can be doubled.
Improve operator proficiency: Reduce roll change and adjustment time, increase effective production time.
Take on OEM processing: OEM processing fee is about 150–200 RMB/ton, adding extra income.
Build your own brand: Move from OEM processing to brand sales, increasing product added value.
Optimize base paper procurement: Base paper accounts for the largest cost; finding a stable, cost-effective supplier is crucial.
V. Investment Advice
The A4-2 production line is suitable for small and medium-sized investors entering the A4 copy paper production field. It has the following characteristics:
Relatively low investment threshold, covers about 1,000–2,000 m²
Only 2–3 operators required, controllable labor cost
Monthly output starts at 300 tons, meeting regional market demand
High equipment stability, low maintenance cost
Core factors affecting profit: Base paper purchase price and finished product selling price. Investors are advised to thoroughly research local base paper supply and finished paper sales channels before project initiation.
