Corrugated box production cost reduction solution II

Third, reduce the cost of corrugated cartons production measures

Reasonable selection of base paper with good quality and low basis weight, “Lightweight puffing, high strength of core paper”; perfect self-inspection means, strengthen self-protection, and control process quality; strengthen technical transformation, tap potential and reduce consumption, make cardboard Use more than 95% of the string to reduce the overall production cost by 7%; eliminate inefficient production processes and equipment, increase production efficiency; strengthen management, reduce costs, increase the ratio of production value to efficiency, and pay attention to the utilization rate of paper and scheduling; introduction; And adopt CAM, CAD system, comprehensively improve product quality, packaging system and display functions, and more flexible packaging products, provide more specialized packaging solutions.

1. Different packaging forms (such as trays, plastic containers, corrugated boxes, strapping, heat-shrinkable films, microwatts, etc.) compare the costs. If heat-shrinkable film packaging, an Ixl2 package can reduce the cost of 1.50 yuan. Calculated with a beer (beverage) factory with an annual output of 100,000 tons, if one-third of products are packaged in heat-shrinkable film, it will save 6.4 million yuan a year (Note: This method is only applicable to transportation distances. 300-500 km). Another example is the diversification of thin corrugated (micro-corrugated cardboard) applications, which are inexpensive. With the same demand, the cost can be reduced by about 30%, and the firmness, flatness and beauty can not be matched by any paper plate; it has better printing performance; it can save the original paper.
About 30%. Because in the production operation process, 3, 5, and 7-layer corrugated cardboard can be produced synchronously and have compatibility, which can save energy and reduce costs for enterprises.

2. Comparing the cost of different printing methods, using flexo printing and pre-printing can reduce the cost by about 10%.

3. The plastic film is changed to a varnish, and the white latex is a starch blend or an eco-friendly chemical glue. The modified nail box is a sticky box, which is environmentally friendly and reduces costs.

4. Reuse of cardboard waste. Convert waste into carton attachments or gaskets.

5. Solve the problem of board warpage, adjust the preheater and preheat roll (paperboard bending caused the production rate to decrease; starch paste, steam and power consumption increase; printing and slotting register accuracy is reduced, resulting in a substantial increase in waste Loss of profits due to solve the problem of paperboard breakage.

6. Strengthen the research on the packaged goods and extend the most effective packaging time.

7. Improve overprint accuracy (high quality printing).

8.5 carton boxes are overpacked, and most of the carton boxes meet the needs of the third floor. The user's packaging cost is therefore reduced by 30% (eg, the United States' 3-carton boxes account for 60-70% of the total corrugated boxes).

9. Using paste automatic control system, essentially solving the problem of production and use of paste in corrugated board production. The waste paperboard was greatly reduced, the average speed was increased by 15%, and the starch consumption was reduced by 20%. The paste viscosity error is controlled within ±2 seconds, and the paste is degenerated to waste zero.

10. The acquisition cost is lower than the new plant and the new customer base, which has the potential of synergies, can meet the requirements of the raw material supply chain, increase profits for the company, and achieve low-cost expansion.

11. Digital management: From production to re-sale to a model of “re-sale after production” is the current direction of efforts to increase the return on investment of printing and packaging companies. If you use a computer management system, save Q (material use, control of paste volume, and temperature control, etc., with little investment, but save at least 3 to 5% less than manual operation. For example, if you change the accuracy of the paper change. , good can be controlled at about 1m, bad error up to 20-30m.

Fourth, corrugated board production line to achieve high quality, high efficiency, low consumption measures

1. Improved quality, reduced paper consumption.

(1) Adjust the pneumatic system of single-sided machines (no high and low pressures will occur);

(2) Instead of a pressure roller, a belt roller can use 90-100g/m2 gram of core paper and liner paper;

(3) proper corrugating;

(4) to properly control the amount of paste before compounding; the ideal bonding state is that the width of the corrugation between the dome and the panel is 1-1.5 mm;

(5) Use a thin knife to make sure that the trim will not break

(6) With the pressure release mechanism, no cardboard chipping will occur at the feed and discharge.

The above improvement measures will increase the flat compressive strength of the board and the compressive strength of the carton by 10-20%, which can save about 10-15% of the basis weight of the core paper and the liner paper. (to be continued)
