Reasonable paper physical indicators
Paper packaging enterprises want to make the physical indicators of the product qualified, we must first ensure that the physical indicators of the paper qualified. For example, a three-layer corrugated box (matching box) requires a compressive strength of 180kg/m2, a circumference of 1000mm, and a height of 300mm. If B corrugated base paper is used to produce, then the quantitative amount of corrugated base paper can not be less than 140g/m2, the corrugated height should not be less than 2.9mm, and the corrugated forming effect should be very good; If C-corrugated base paper is used to produce, then the quantitative quantity of the corrugated base paper can not be less than 130g/m2, and the corrugated height is 3.7 ~ 3.8mm. However, these data are in the corrugated base paper ring pressure index is higher (8.0N? m/g) if the ring pressure index of corrugated base paper is lower than 7.0N? m/g, then the quantitative C corrugated base paper can not be less than 150g/m2.
Paper selection skills
The cost control of paper is not arbitrary, but there are certain restrictions. Well controlled, you can effectively control the input of other costs; Improper and reasonable paper control is one of the key factors to control the cost of paper.
1. Meet customer requirements
The products produced by paper packaging enterprises must first meet the requirements of customers, which is the first element and the first premise, otherwise other aspects (such as cost minimization, profit maximization, etc.) can not be achieved.
2. Paper quality is moderate
The key to paper packaging enterprises is to minimize the cost of paper under the premise of ensuring product quality, that is, the physical indicators of the paper used are just enough to ensure the quality of the product (that is, to reach a critical point), so that there will be neither product quality problems nor waste paper. Once the physical index of the paper is below this critical point, the comprehensive cost of the product will not only not reduce, but increase. This is because when the physical index of the paper is lower than the critical point, the lower the physical index of the paper, the lower the pass rate of the product, and the higher the comprehensive cost of the product. This part of the cost is mainly caused by a series of losses caused by unqualified product quality, such as returns, rework, redo, order loss, etc.
3. Suitable for large-scale operation of high-speed automation equipment
With the continuous improvement of the degree of automation of paper packaging processing equipment, as well as the increasingly fierce market competition, some large and medium-sized paper packaging enterprises have introduced high-speed automation equipment, and these devices have strict requirements for the quality and grade of raw and auxiliary materials. Therefore, when choosing paper, it should be ensured that it is suitable for large-scale operations of high-speed automation equipment, so that the quality of semi-finished products of each process can be successfully reached, and the overall production efficiency of the product can be improved to a certain extent. Once a process operation is not smooth, the overall production efficiency of the product will decline, the cost of the product will rise, and the profit of the product will decline, this lever principle is immutable.
For paper packaging enterprises, product costs should be calculated on the basis of the actual comprehensive cost, rather than simply the price of a certain raw and auxiliary materials. The price of a certain raw and auxiliary material is only one side of the product cost, and the sum of other related costs brought by this cost is the real product cost, and the cost of paper is a good example. How to control the cost of products to a minimum is not simply to reduce the price of paper can be achieved.
I hope that through this article, we can help the industry to clarify their ideas, find a reasonable way to use paper, and find a way to save costs that is most suitable for them.
