With the development of the global packaging industry and logistics industry, the requirements for the quality of packaging cartons are getting higher and higher, especially for the long-distance transportation of the packaging box. The printing effect is poor due to the uneven warpage of the cardboard, the moisture absorption is soft and the product is caused by the glue opening. Cases such as damages or scraps, returns, claims, etc. occur from time to time. It can be seen that the quality of the packaging carton is critical to the packaging logistics industry. So, what are the materials for the packaging carton?

The carton is commonly used in three layers and five layers. The layers are divided into inner paper, corrugated paper, core paper, and facial tissue. There are teaboard paper, kraft paper, and corrugated paper for core paper. The color and feel of various papers are different. Different papers (colors, feels) produced by different manufacturers are also different. The following is an introduction to the various base paper materials for small-sized carton packaging:

1. Teaboard paper: The color of the teaboard paper is grayish and rough, and the teaboard paper with the old material is added. The fiber composition is less and the quality is normal. The teaboard paper is the paper in the middle of the carton corrugated, which is very soft. Because of the poor quality, teaboard paper prices are also the cheapest.

2. Cardboard paper:

(1) Kraft paperboard (Mika, Russia). Features: long fiber, heavy sizing, high physical strength, rough cardboard; pure wood pulp or a small amount of OCC. Abbreviation: Imported cattle card. Imported paper prices can be expensive and difficult to order.

(2) Imitation kraft paperboard. Features: 15-25% wood pulp on the surface, the rest is OCC; the fiber is shorter and the strength is worse than the cattle cardboard. The paper surface is flat, different degrees of sizing (water absorption of 30-55g/m2), surface dyeing treatment. Abbreviation: domestic cattle card.

(3) White cardboard. White-faced cow bottom, the surface is bleached with wood pulp, and the rest is natural or dyed wood pulp. (Russian white, Swedish white card, Finnish white card); white paper (surface bleached wood pulp, the rest is deinked or non-deinked waste paper); coated white paper (white on white, gray on white, etc.).

(4) Recycled paper. All are made up of OCC, but different from corrugated paper. The surface is 11# or more of the AOCC noodles and is dyed). The market is generally referred to as C-class cardboard, partially referred to as T-paper.

3, corrugated base paper: corrugated paper is a multi-layered adhesive, it is composed of at least one layer of wavy core paper sandwich and a layer of cardboard. It has a high mechanical strength and can withstand collisions and falls during handling.

Since the corrugated carton package has the functions of strong protection of the contents, easy identification, easy handling, easy unpacking, and exquisite printing, it has become one of the fastest growing product packaging forms in recent years. Recently, affected by the Sino-US trade war, the US card has increased tariffs. It is difficult to set such a paper now, and there will be more domestic cattle cards. Various products exported to the United States have increased tariffs, reduced exports, and reduced demand for packaging. The paper produced by each paperboard factory is different and the price is different, so you should listen to the opinions of the carton factory professionals.
