Liyang Paper Printing Talking about Corrugated Paper Box

At the near two years. the popular corrugated paper box is mailer shipping box, some one call Ecommerce box or postal box. They can be design well and beautiful for gift packaging, strong paper suit for shipping at the same time.

According to use classification

Packaging corrugated cardboard

The so-called classification according to the structure is similar to the classification based on the use of several sheets of core paper and facial paper.

First, single-sided corrugated cardboard

Single-sided corrugated cardboard As shown in the above diagram, there is a face paper on one side of the corrugated core paper. The name is defined according to the number of sheets used. The single-faced corrugated paperboard is not directly used to make a corrugated box, but rolled into a paperboard. Cylindrical or cut to a certain size, used as a buffer material and a fixing material.

Second, double-sided corrugated cardboard (three-layer corrugated cardboard) commonly known as single corrugated double-sided corrugated cardboard as shown in the corrugated paper on both sides of the surface of the paper and made.楞 type can use A, B, C, E which can be. At present, the most used cardboard boxes in the world are double-sided corrugated cardboard.

Third, double-watt double-sided corrugated cardboard (five-layer corrugated cardboard) commonly known as double corrugated
Double-Watt double-faced corrugated cardboard is made using two layers of corrugated cardboard plus a piece of paper, ie, a piece of single-sided corrugated cardboard and a piece of double-sided corrugated cardboard. In terms of structure, it can use a variety of 楞 type combinations, so its performance is also different. Because of its normal double-faced corrugated board, its performance in all aspects is stronger than that of double-sided corrugated board (three-layer corrugated board), especially its vertical compressive strength, which is obviously improved by double-core corrugated cardboard ( Corrugated cardboard boxes made of five-layer corrugated cardboard are used in the packaging of fragile items, heavy items, and long-term preserved items (such as fresh vegetables, fruits, etc., which contain a lot of moisture).

Four or three-watt double-faced corrugated cardboard (seven-layer corrugated board) commonly known as three-watt corrugated board

The three-core double-sided (seven-layer) corrugated cardboard is made of three-layer corrugated cardboard, ie, a two-tile double-faced corrugated cardboard is attached to a single-faced corrugated paper. Similar to double-tile double-sided (three-layer) corrugated paper, various combinations of A, B, C, and E can be used. Structurally, this type of corrugated paperboard using a combination of three types of corrugated board is stronger than a double-watted double-sided (three-layer) corrugated board made of a combination of two types of corrugated board. Therefore, such a three-watt double-sided corrugated board is used. Corrugated cartons made of cardboard are mostly used for packing heavy items in place of wooden boxes in the past, and such cartons are not limited to being used alone, and are often combined with wooden trays and pallets. The combination of the two is fixed with a steel belt or a special box nail.

Corrugated Boxes Product Types There are a large variety of corrugated cartons, which can be roughly divided into three categories according to their structure:
Slotted cartons (02 type)

The slotted carton is the most basic type of box in the transport package and it is also the most widely used type of carton. It consists of a piece or pieces of processed corrugated board, which is a combination of stapled or bonded cartons. Its bottom and top flaps (upper and lower flaps) form the bottom and the lid. Such cartons can be folded and laid flat during transportation and storage, and have the advantages of small size, convenient use, sealed and dustproof, and clean interior and exterior.

Fitting carton (03 type)

The nested carton consists of one or more pieces of processed corrugated cardboard. The feature is that the box and the lid are separated, and the sleeves are used when they are used. The advantages of this kind of carton are that it is convenient for packing and sealing, and it is not easy to fall off after the goods are loaded. The overall strength of the carton is higher than that of the slotted carton. The disadvantage is that the sleeve is of a large volume after being synthesized, and transportation and storage are inconvenient.

Folding carton (04 type)

Folding carton, also known as a special-shaped carton, is usually composed of a piece of corrugated cardboard, which is folded to form the low, side, and lid of the carton without being stapled and glued.

Corrugated box accessories

In order to protect the goods from being damaged during transportation, according to the characteristics and requirements of different products, it is necessary to design a reasonable structure of accessories to protect the goods. The most basic carton attachments are the following:

A. Baffle: For packaging of fragile and fragile items for bottles, separate each item in the box to prevent shaking and collision.

B. Lining: Lining is basically made of three, one is a full liner, used for layered stacking for multiple layers inside the box. The second type is the bridge lining plate, which is used to cover the gap in the carton. The third type is liners. In order to improve the compressive strength of the carton and protect the goods, the liner is surrounded on all four sides of the carton.

C. Liner: According to different shapes and weak parts of the merchandise, a variety of liners are designed to fix the merchandise to ensure that the merchandise will not move in the process of transportation, but also has a buffering effect.

The advantages of corrugated carton

Corrugated carton is a paper packaging container made of corrugated cardboard. It has a lot of advantages:

1, light weight, good structural performance. The corrugated structure within it is similar to an arched structure, which can play a role in anti-shock and shock absorption, and has good mechanical properties.

2. There are many good protection functions for packaged goods. For example, moisture-proof, heat-dissipating, easy-to-handle, etc

3, low transportation costs, and easy to achieve the mechanization and automation of packaging and transportation.

4. The change of specifications and dimensions is easy to implement and can quickly adapt to the packaging of various types of articles.

5, sealing, strapping are convenient, easy to automate operations.

6, can adapt to various types of carton decoration printing, can be a good solution to product protection and promotion issues.

7. The waste bin is easy to recycle and meet the environmental protection requirements.

8, can be combined with various coverings or moisture-proof materials, and greatly expand its scope of use.
