Corrugated cardboard is a multi-layer glued body, it is at least composed of a layer of corrugated core paper (commonly known as “pit sheet”, “corrugated paper”, “corrugated core paper”, “corrugated paper core”, “corrugated base paper”) and a layer It is composed of cardboard (also known as “boxboard paper” and “boxboard”), which has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: core paper and The characteristics of the cardboard and the structure of the carton itself.
Also known as corrugated cardboard, it is made of at least one layer of corrugated paper and one layer of cardboard paper (also called cardboard), which has good elasticity and extensibility. Mainly used in the manufacture of cartons, carton sandwiches and other packaging materials for fragile commodities. It is mainly made of earthen straw pulp and waste paper through beating to make raw paperboard similar to yellow paperboard, which is then mechanically processed and rolled into a corrugated shape, and then glued to the cardboard paper with adhesives such as sodium silicate on the surface.
The corrugated corrugated corrugated cardboard is like a connected arched door, arranged in a row and supporting each other to form a triangular structure. It has good mechanical strength, can withstand a certain pressure from the plane, and is elastic and cushioning. Good function; it can be made into cushions or containers of various shapes and sizes according to needs, which is simpler and faster than plastic cushioning materials; it is less affected by temperature, has good shading, and does not deteriorate by light, and is generally less affected by humidity. But it is not suitable for long-term use in a humid environment, which will affect its strength.
According to different combinations, corrugated cardboard can be divided into the following five types:
1. The cardboard composed of a layer of core paper and kraft card is called “corrugated cardboard”. Corrugated cardboard is generally only used for cushioning, spacing and wrapping irregularly shaped objects.
2. The cardboard composed of one layer of core paper and the upper and lower layers of kraft cards is called “single-pit cardboard”.
3. The two-layer core paper sandwiched in the three-layer kraft card is called “double-pit cardboard”. Double-pit cardboard can be composed of pit paper with different pit widths and different paper qualities, such as “B” pit paper with “C” pit paper.
4. The three-layer core paper sandwiched in the four-layer cowhide card is called “three-pit cardboard”.
5. Extra-strong double-body paperboard is developed from single-pit paperboard, and the middle layer of core paper is made of two thick core papers laminated together.
Made by corrugated cardboard, paper shelves (paper display racks) was popular in Europe and the United States in the early days. The beautifully printed paper shelves (paper display racks) have become very common in foreign countries and are widely used in food, daily chemicals, home appliances, electronics, clothing and other industries. Many packaging companies in Europe and the United States also recognize, in order to improve the technical level of the enterprise and the sales ability of the enterprise through the production of paper shelves (paper display racks). In Europe and America, the paper shelf (paper display shelf) is a very high value-added product, and it is used by many users and manufacturers.
Now some brand customers have used paper shelves (paper display racks) as regular promotional items in the system. Whether it is new product launches or holiday promotions, good results have been achieved, which can enhance the brand image in the store and create a festive atmosphere. Increasing sales is of great help.
