There are different kinds of packaging and transportation in the world, and corrugated boxes stand out because of its light weight and versatility, which makes it easier to transport and sell products.
Today's corrugated boxes occupy an important position in the sales of the product market. Its brand-new image comes from an unflattering “paper trunkâ€. Please take a look at the multiple functions of the corrugated box:
The style, shape and design of the carton make the product package lively and also make the product more efficient in terms of shipping and storage. Exaggerated patterns, pleasing colors and unique shapes can all attract attention, so as to achieve the effect of speeding sales. Carton printing on the content, size, quantity, use instructions and handling instructions and other information, can make your product intact and quickly arrived at the destination.
Corrugated paper products can use recycled resources and are also suitable for reconstructing corrugated cartons. Wood cartons are made of wood fibres. Wood fibres can be decomposed by natural action; wood will not be depleted under planned planting and harvesting. Most of the discarded corrugated cartons can be recycled to create new paper materials, which is a great contribution to environmental protection.
What is corrugated cardboard?
Corrugated cardboard is a multi-layered adhesive body consisting of at least one layer of corrugated core paper sandwich (commonly known as "knock sheet" or "corrugated paper") and a layer of cardboard (commonly known as "psoriasis"). It has high mechanical strength and can withstand collisions and falls during handling.
The actual performance of a corrugated box depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.
Corrugated board classification According to different combinations, corrugated board can be divided into the following five types:
1) The paperboard consisting of a layer of core paper and psoriasis is called "Galpa Cardboard". The corrugated cardboard is generally used only for cushions, spaces and irregularly shaped objects.
2) The cardboard consisting of a layer of core paper and two layers of psoriasis is called "single-hole cardboard".
3) Two-layer core paper is divided into three layers of psoriasis called "dual pit cardboard". Double pit cardboard can be composed of pit papers with different pit widths and different paper qualities, such as "B" pit paper with "C" pit paper.
4) Three-layer core paper is divided into four layers of psoriasis called "three-hole cardboard".
5) Extremely strong cardboard is developed from single-deck cardboard. The middle layer of core paper consists of two thick core papers stacked on top of each other.
Fortunately, today we have been able to produce many different combinations of corrugated board with different qualities and strengths to meet the changing needs of the market.
The type of pit pattern:
The corrugated board can be further subdivided according to the size of the pit pattern on the core paper, ie its height and the number of pits per unit length. There are four kinds of paper core pits. The following table shows the paperboard produced by Mitsubishi and Langston pit machines.
... The carton caused by the thicker "A" pit has a better top and bottom crushing strength than "B" and "C" but is thinner in comparison with "A" and "B" pits. The "B" pit pattern has superior anti-pressure properties. The "A" and "C" pits are used in the manufacture of cartons that are under pressure and packaged and require padding. The "B" pit pattern is suitable for carton manufacturing where capacity and space are important and stacking strength is less important.
The "E" pit has the highest compressive resistance, but its shock absorbing ability is slightly inferior. It is mainly used on offset (color printing) corrugated boxes that carry heavy objects. The larger the hole diameter of the core paper material corrugated board, the stronger its rigidity. The toughness of the board is derived from the core paper layer without the need for hard fillers. This will reduce the weight of the board and its cost. Core paper can be caused by semi-chemical pulp, which provides the best paper strength, and recycled paper stock. The latter, because of its low manufacturing cost, is happy to be adopted by Hong Kong manufacturers. Although the paper strength is not as good as the former, it can be improved by adding paper grade starch to paper mills.
The pit pattern holds a certain space in the corrugated paper, and its role is also very important. It can withstand flat pressure, lateral pressure and other irregular pressures. (To be continued)
