Corrugated box design and its quality control

The corrugated carton is environmentally friendly materials for modern product packaging, it is an economic, practical packaging to protect products and to facilitate product storage, handling. Carton packaging production used widely within the packaging of products and outsourcing, cartons four sides printed in bright colors and eye-catching illustrations, enable the built-in products play a good publicity and promotional role, so we must pay attention to the rational corrugated box design and product quality control.

The rational design and adaptability of the corrugated box

How to design specifications of corrugated box, on the one hand, it relates the cost of the product packaging, on the other hand, it relates to the protective properties of the product. The specifications can be divided into three categories according to the consolidated size large box within 2000 mm, smaller than 2000mm but greater than 1000 mm are medium-sized box; smaller than 1000 mm is small box. If the corrugated box design is too large, it not only caused by the waste of materials, in the transport or handling process, the product are likely to cause damage to the goods. Conversely, if the carton size is too small, then, the product will not fit or squeeze too, so that the carton easy to crack, damage, would not achieve a better protective effect. It also consider the weight of the built-in products, if the specification is too large the weight of the loaded, it will cause handling difficulties. On the contrary, the weight specification is too small it installed, it will affect the efficiency of packaging and handling.

The relationship between the corrugated box structure and the compressive strength

The most important feature of the corrugated box is the good protection with the goods, while the overall compressive strength of the carton is a carton to protect the performance of the embodiment of the importance of the compressive strength of the carton is self-evident. The data analysis showed that the compressive strength and carton perimeter, height and the length width ratio has a certain relationship. The perimeter longer, the higher the compressive strength has, the cartons circumference and the compressive strength of conversion relations. The the corrugated box structural design affects the strength greatly.

The quality control of the corrugated box specification

Once the design specifications for corrugated box confirmed, it must be in accordance with the standard production to meet the requirements of users, but also in the daily production process there is no lack of specification deviation light situation affect the normal performance of the use and protection. It caused heavy batch scrap such as carton forming size once obviously too small to make the product fit or barely fitted under the destruction box, carton design and production. to fully take into account certain factors affect the quality control such as the caliper of the corrugated box, the binging, the lapping tongue, the moisture content, the die cut, the folding line and the climate. Those all factors should be take into account into quality control of the corrugated box specification.

Number of elements of the corrugated carton strength design

The strength of the corrugated box a direct impact on product packaging and protective properties, which will affect the performance of carton strength depends mainly on the base paper quality grade, base paper quantitative flute features structure, corrugated board thickness and moisture content.To improve the strength of the corrugated box, firstly it should select the quality grade and quantification of the base paper, secondly it is the rational structural design of cartons. thirdly according to the characteristics of the product. reasonably determine the corrugated board corrugation waveform, the number of layers and thickness; fourthly reasonably designed to ensure that the focus on the production process of corrugated cardboard forming the strength is the use of waste to the die-die-indentation of the production process. fifthly maintain the clarity of the folding line.

In summary, corrugated box design and quality control involved in all aspects as long as we correctly understand and grasp the factors affecting the carton strength. The reasonable control of the production process according to the product packaging characteristics of science, with special emphasis on product quality source of control the whole process of the production process from the production design to rigorous technical checks and control, not only can effectively reduce or avoid a variety of quality, the theme of opportunities, but better to mention the high production efficiency and product processing quality to meet the requirements of users.
