The demand for corrugated cardboard is closely related to the production volume of various commodities and logistics and transportation. With the rapid development of e-commerce, the demand for corrugated cardboard has been directly driven. In addition, with the improvement of global environmental awareness, corrugated cardboard, as a recyclable material, has been favored by more and more consumers, and the market demand has shown a steady growth trend. In this article, we will explore the most critical parameters in the production of corrugated cardboard and explain why they are so important.
Why are key parameters so important in corrugated board production?
Key parameters in corrugated board production include: base paper quality, fluting shape, environment and gluing machine. The right combination of these factors ensures that the board is cost-effective and meets the packaging needs of the market. These parameters affect everything from stacking strength to flexibility and cost-effectiveness.
How the Choice of Raw Paper Affects the Final Product?
The quality requirements of base paper vary depending on the object, environment and function of its use. The performance indicators and quality requirements of base paper directly affect the quality of carton packaging products, mainly including the physical performance indicators, appearance quality and surface performance requirements of base paper.
Flute Geometry: The Role of Flute Size in Determining Strength and Performance
Corrugated geometric flutes include A-type flutes, B-type flutes, C-type flutes and E-type flutes, each of which has different advantages :
- type flutes Advantages: Suitable for packaging lighter items, with greater cushioning force.
- type flutes Advantages: Suitable for packaging heavier and harder items, mostly used for packaging canned and bottled items. In addition, there is a tendency to use the hard and unbreakable characteristics of B-type flutes to make complex-shaped combination boxes after punching.
- type flutes Advantages: The number of flutes per unit length and the flute height are between A-type flutes and B-type flutes. The performance is close to A-type flutes. In recent years, with the increase in storage and transportation costs, the smaller C-type flutes have attracted people’s attention and have now become the flute type adopted by European and American countries.
Adhesive Quality: Why the Right Glue Matters in the Production Process
Adhesive plays a vital role in corrugated board production, which directly affects the physical properties of the board and the quality of the final product. The following is the impact of adhesive on corrugated board production
Adhesive strength: The quality of the adhesive determines the adhesive strength of the corrugated board. If the adhesive strength is insufficient, it may cause the cardboard or face paper to easily separate from the corrugated paper, causing a series of quality problems, such as reduced board quality, substandard thickness, etc.
Environmental Factors: The Impact of Humidity, Temperature, and Other Factors on Cardboard Quality
The difference in ambient humidity can have a great impact on the performance of corrugated cardboard. For example, in the low humidity range (below 50%), the lower the relative humidity, the lower the puncture strength of the corrugated cardboard; in the high humidity range, the higher the ambient humidity, the lower the puncture strength. This is because paper fibers become brittle at low humidity, and become loose after absorbing moisture at high humidity, which reduces the strength; for another example, too much humidity can cause the paper to absorb moisture, thereby weakening the cardboard and making it easier to tear. On the other hand, an overly dry environment can make the paper brittle, leading to cracking and reduced flexibility.
Impact of these parameters on corrugated board strength
Each of these key parameters affects the strength of corrugated board in a different way. When one of these factors is affected (such as using low-quality paper or weak glue), the entire integrity of the board may be affected.
The geometry of the fluting determines the weight that the board can resist, as well as the overall stacking strength. Therefore, it is crucial to choose the right fluting profile for a specific use case.
How to ensure consistency in corrugated board production
Ensuring the consistency of these parameters is critical. By strictly monitoring the quality of raw materials, the application of adhesives, and the formation of corrugations, manufacturers can produce corrugated board that consistently meets the required strength standards. Of course, corrugated paper, carton and board testing is a very important testing task. It mainly tests the various properties of corrugated paper, cartons and paperboard to ensure product quality and improve production efficiency. This test can be carried out by a variety of means, such as pressure testing, abrasion testing, water resistance testing, tensile testing, etc.
Summary
In the production of corrugated board, parameters such as paper quality, corrugation shape and adhesive quality are crucial to the production quality of corrugated board. The above factors are interrelated and work together in the production process of corrugated board. In order to ensure product quality, these factors need to be fully controlled and managed to improve the quality of corrugated board production in the factory.
