During the manufacturing process, it is common to encounter issues such as boxes collapsing, which can be a major headache. However, there are ways to address the problem. One solution is to improve the cardboard material by enhancing its compressive strength and moisture resistance. This can significantly reduce the rate of box collapse and ensure better quality products. Additionally, some factories may need to focus on improving the adhesive strength of the carton gluing machine. This can involve increasing the density of starch paste to boost solid content, while reducing the amount of glue used to improve the hardness of paperboard. By taking these steps, manufacturers can effectively solve the issue of poor adhesion and produce high-performing cartons.
To avoid case collapse caused by poor adhesion of the case gluing machine, it is important to pay attention to certain factors during production and use. These include careful monitoring of the level of adhesive being used, ensuring that the proper temperature and humidity conditions are maintained, and using the right amount of pressure to properly seal the case. Additionally, it is important to regularly inspect the machine to ensure that it is functioning properly and that any necessary repairs or maintenance are carried out promptly. By taking these steps, you can minimize the risk of case collapse and achieve a high-quality finished product.
1. Control the use of base paper
To ensure the quality and durability of corrugated paper, it is essential to consider the sizing of the paper and the water absorption index of its base. A poor surface sizing can result in high water absorption, which can be particularly problematic in cold and damp storage environments. Moisture regain, softening, and reduced compressive strength may occur as a result. Therefore, it is important to carefully assess these factors and take appropriate measures to ensure the paper remains in good condition and maintains its structural integrity over time.
Maintain proper moisture levels during paperboard production to ensure quality results. It is important to regulate moisture content to prevent issues such as warping or degradation of the material. By controlling moisture levels, paperboard can maintain its structural integrity and overall performance.
To ensure the optimal hardness and edge pressure index of paperboard, it is important to maintain an appropriate moisture content. If the moisture content exceeds a certain level, the paperboard will become too soft and pliable, affecting its durability. During the processing stage, it is crucial to be mindful of the amount of glue applied on both the single-side and double-side machines. Over-application of glue can lead to deformations in the corrugated shape of the paperboard, which in turn impacts its overall strength and compressive properties. Therefore, it's essential to apply the right amount of glue to maintain the structural integrity of the paperboard.
It is important for cardboard to have a strong adhesive capability in order to ensure stability.
The strength of adhesion plays a critical role in determining the integrity of corrugated paper, lining paper, and face paper. Should the adhesion prove false during processing, the face paper and lining paper could become detached from the corrugated paper upon compression, leading to a linear decrease in compressive strength. It is therefore essential to ensure a reliable and durable adhesive bond throughout the manufacturing process to maintain the overall structural integrity of the paperboard.
It is important to maintain a moderate clearance pressure control during the production process.
The importance of maintaining appropriate gap pressure cannot be overstated when it comes to operating certain machines in the packaging industry. For instance, when using a box pasting machine, it is crucial to ensure that the gap pressure between the paste and the box is not too small. Similarly, on double-sided machines and die-cutting machines, the gap pressure applied to the sun wheel should be carefully controlled within a reasonable range. Failure to do so could lead to the deformation of the corrugated shape, ultimately compromising the compressive strength of the cardboard. Hence, it is essential to prioritize the proper management of gap pressures to guarantee optimal results in the production process.
To address the issue of surface waterproofing and moisture-proofing, one can employ the use of waterproof varnish and a water splashing agent. By applying these products, you can effectively solve the problem and protect the surface from water damage and moisture infiltration.
When it comes to printing on cardboard, it is crucial to maintain appropriate pressure levels throughout the process. Any excess pressure can result in the crushing of the corrugated type, which in turn leads to deformation of the corrugated material and affects the cardboard's compressive strength. Thus, it is important to keep a check on the printing pressure to ensure the quality and durability of the cardboard.
It should be noted that extended periods of storage can cause boxes to become softer, even in controlled environments with constant temperature and humidity levels. Therefore, it is important to consider the duration of storage when selecting the appropriate packaging materials for products.
The way in which boxes are stacked during storage can have a significant impact on their strength. Various stacking methods, such as cantilever stacking and staggered stacking, can weaken the corrugated boxes' compressive strength. Other methods, such as wolf tooth cross stacking and shelf-free stacking, can also have a negative effect. Therefore, it is essential to choose the right stacking technique to ensure the strength and durability of the boxes during storage.
Apart from the jolting and bouncing experienced during transit, manual handling and turnover times also contribute to the risk of boxes collapsing. It's essential to take every possible precaution to avoid these accidents and thereby reduce the likelihood of damaging our heavy-duty cardboard boxes. Keeping these factors in mind and taking the necessary steps towards preventing them will go a long way in ensuring the safety and stability of our products during transportation.
