Cartons for food packaging can be roughly divided into two categories: one is complete food packaging cartons that are nailed or pasted, and the form of food packaging cartons is butt joint. The other is to provide only plates that have undergone printing and die-cutting processes, which is called machine case in the industry.

1. Several actions to be completed in the process of food packaging with cartons are the key points. Pay attention to whether the cartons or plates for food packaging are smooth after being sent into the packaging line, and there should be no jam. Therefore, when packaging cartons for food packaging, we should go deep into the production line together with users, participate in debugging together, and immediately improve the design to solve problems if they are found.

2. In addition to the consistency of the determined size, the creasing of the food packaging carton is an important part. The automatic packaging line is completed by many mechanical devices and manipulators. If the creasing is not in place or the depth of the creasing is not enough, the food packaging carton cannot be formed or the forming is not in place, which will cause the failure of the packaging action and serious blockage and stop the line.

In particular, the food packaging carton is crimped at the flap, because the hot melt adhesive is generally used for bonding and molding in the automatic line packaging. If the crimping cannot meet the requirements of the automatic packaging line, the molding is not very good, and the molding is not in place, the bonding effect will be poor, and the production of loose packages will not pass the production line seriously.

To sum up, the manufacturer of food packaging cartons, color printing packaging cartons and corrugated packaging cartons will share relevant matters with you. More information about food packaging cartons, color printing packaging cartons and corrugated packaging cartons, please lock in Hansen for more details!

Especially the crimping at the flap of the carton used for food packaging, because the hot melt glue is usually used for bonding and forming in the automatic line packaging. If the crimping fails to meet the requirements of the automatic packaging line, the molding is not in place, resulting in poor bonding, and serious loose packages cannot pass the production line.

Nowadays, with the implementation of energy conservation and emission reduction and environmental protection policies, corrugated packaging cartons are used more and more widely.

However, it is precisely because of the wide and frequent use that the more deficiencies and deficiencies appear. So, what aspects of corrugated packaging carton need to be improved?

1、 Sizing degree:

In order to adapt to the high temperature and humid climate in the south and the needs of refrigerated packaging, corrugated packaging cartons should have a certain sizing degree;

2、 Wet strength:

In order to adapt to refrigerated packaging and keep a certain compressive strength of packaging carton under low temperature and humid environment, corrugated packaging carton should have a high wet strength;

3、 Folding resistance:

In the production process of cartons, craters, indentations and corners are required. When cartons are used, covers need to be rolled. In order to avoid cracks in the process of craters, corners and covers, corrugated packaging cartons need to have a certain degree of toughness and folding resistance.
